BUILDING AUTOMATION SYSTEMS (BAS)
Building Automation is the automatic centralized control of a building's heating, ventilation and air
conditioning, lighting and other systems through a Building Management System or Building Automation System
(BAS). The objectives of building automation are improved occupant comfort, efficient operation of building
systems, and reduction in energy consumption and operating costs.
A BMS consists of software and hardware; the
software program, usually configured in a
hierarchical manner, can be proprietary, using such
protocols as C-bus, Profibus, and so on, recently,
however, new vendors are producing BMSs that
integrate using Internet protocols and open
standards such as Device Net, SOAP, XML,
BACnet, Lon Works and Modbus.
BUILDING AUTOMATION SYSTEM (BAS):

Intelligent architecture refers to built forms whose integrated systems are capable of anticipating and responding
to phenomena, whether internal or external, that affect the performance of the building and its occupants.
Intelligent architecture relates to three distinct areas of concern:
1 intelligent design;
2 appropriate use of intelligent technology;
3 intelligent use and maintenance of buildings.
requires that the building design responds to
humanistic, cultural and contextual issues; that it
exhibits simultaneous concern for economic,
political and global issues; and that it produces an
artificial enclosure which exists in harmony with
INTELLIGENT BUILDING PYRAMID.
What is Building Automation in HVAC systems ?
Provide heating, cooling, ventilation, air filtration, and
humidity control to building spaces
Respond to varying ambient environmental conditions to
maintain building occupant comfort
Often have complex sequences of operation
Typically highest energy consumer in building
Modern building control systems had their roots in
controlling HVAC systems
WHAT IS THE NEED OF BAS ?
Keeps the building climate within a specified range.
Provides lighting based on an occupancy schedule.
Monitors system performance and device failures.
Provides malfunction alarms (via email and/or text
notifications) to building engineering/maintenance staff.
Reduces building energy and maintenance costs when
compared to a non-controlled building.
WHAT IS CONTROLLED ?
Generally, building automation begins with control of
mechanical, electrical, and plumbing (MEP) systems.
For instance, the heating, ventilation, and air-conditioning
(HVAC) system is almost always controlled, including
control of its various pieces of equipment such as :
Air Handling Units (AHUs)
Roof-top Units (RTUs)
Fan Coil Units (FCUs)
Heat Pump Units (HPUs)
Variable Air Volume boxes (VAVs)
The advantages of all- air systems are as
• separation of mechanical areas and major
equipment from occupants;
• possibility of using outdoor air for cooling
• flexibility to outdoor and occupancy changes;
The disadvantages of all- air systems are:
• they require close cooperation between
architectural, system and structural designers
to ensure accessible terminal devices.
CONTrOL AND OpTIMIzATION Of AIr-CONDITIONING SYSTEMS
TYPICAL CONTROL LOOPS OF THE AIR- CONDITIONING PROCESS
1. Typical air- side systems
The types of air- side air- conditioning systems include all- air systems, air water systems, and all- water
systems. Constant air- volume systems and variable air- volume systems are two major categories of all- air
systems concerned with air flow control. Regarding ductwork design, these systems can be further divided into
single- duct systems and dual- duct systems.
2. Cascade control
Cascade control can be used when there are several
measurement signals and one control variable. It is particularly
useful when there are significant dynamics between the control
variable and the process variable. Cascade control can be
categorized into two kinds. One is called basic cascade control,
built up by nesting the control loops The other is called
reconfigured cascade control, which is tailored for specific
3. Sequential split- range control
It is used when there is one measured variable and several
control variables. Systems of this type are common in air-
conditioning control such as when heating and cooling are
provided simultaneously. One physical device is used for
heating and another for cooling.
4. Two- position control and on/off control
Most building processes are controlled by continuous
modulating control. However, there are still many processes
controlled using two- position control primarily due to the low
cost of the control actuation devices. Fan- coil units and room
air- conditioning units often employ a two- position control The
difference between the ‘on’ and ‘off’ points of the thermostat is
called the control differential. The difference between the high
temperature and low temperature in the room is called the
5. Temperature controls
Temperature control is the most fundamental function of air-
conditioning systems. Temperature control is often done by a
temperature controller called A thermostat which is set to the
desired temperature value or set- point. The temperature
deviation, or offset, from the set- point causes a control signal to
be sent to the controlled device.
6. Humidity control
Humidity control in a conditioned space is either for thermal comfort or Industrial processes, which is done by controlling the
amount of water Vapors present in the air in the space. When relative humidity at the desired Temperature set- point is too
high, dehumidification is required to reduce the Amount of water vapor in the air for humidity control. Similarly, when relative
Humidity at the desired temperature set-point is too low, humidification Is required to increase the amount of water vapor in
the air for humidity Control. Commonly used dehumidification methods include:
• Surface dehumidification on cooling coils simultaneous with sensible Cooling;
• Chilled water spray dehumidification with direct contact;
• Direct dehumidification with desiccant- based dehumidifiers.
• Commonly used Humidification methods include: water spray humidification and steam Spray humidification.
7. Static pressure control
In a variable air volume system, the supply air volume delivered varies with the building load. It is necessary to provide some
means of fan capacity modulation and static pressure control in the duct system. Static pressure control will prevent excessive
noise generation and energy loss as the variable air volume system reduces the demand of air volume. Damper throttling can
offer a low cost method of controlling air flow rate.
There are four typical types of fans with variable capacity usually used in
1 variable- speed centrifugal fan;
2 axial fan with variable pitch angle;
3 fan with variable inlet vanes;
4 fan with variable outlet vanes.
Control of CAV systems
The air- handling unit is one of the most important components in HVAC systems. The processed air can provide heating or
cooling, adjust the humidity and refresh the air for each conditioned zone. The control system must be able to optimize the
temperature, humidity and fresh air ratio in the supply air to provide comfortable air with minimum energy consumption.
The components of the air- handler include
heat exchanger coils,
The system and its control which is a single- duct heating and
cooling air- handling system with a return air fan and a supply air
fan. The system is hot water or steam heating and chilled water
cooling. It also uses an economizer control cycle to control an
outdoor air (O.A.) damper. Usually outdoor air, return air (R.A.) and
exhaust air (E.A.) dampers are interlocked. Generally, supply air
leaving the cooling coil after surface dehumidification is often near
a saturated condition and can meet indoor humidity requirements in
cooling seasons. Therefore, no special measure is needed to control
supply air humidity in cooling seasons.
Control of VAV systems
Variable air volume systems represent one major type of HVAC system in use today. VAV systems are the results of
developments of fans, motor drivers, air diffusers and control in response to global energy crises. VAV systems are divided into
single- duct systems and dual- duct systems. In single- duct VAV systems, the supply air temperature is controlled to be
constant or is reset by optimized supervisory control while the supply air volume changes to satisfy the cooling load. As the
volume of the supply air to the zones through the terminal units (VAV boxes) changes, the air volume delivered by the fan must
also be adjusted. The control methods employ mainly motor- actuated variable inlet vanes on the fan, variable- speed fan and
variable pitch angle.
Control of VAV air- handling units
Outdoor air ventilation control and optimization
Demand- controlled ventilation
Economizer control and its performance
Economizer control can be employed to save energy when it is
beneficial to do so. In the cold season, economizer control can
be employed to keep a minimum supply of fresh air. When
temperature increases, cooling is required. Meanwhile, if the
temperature (or enthalpy) is lower than that of return air,
economizer control can be used to regulate the fresh air damper
to introduce fresh air to maintain the supply air temperature at
This packaged HVAC system has an economizer.
Demand- controlled ventilation
Outdoor ventilation airflow is one of the key factors affecting air quality in air- conditioned indoor spaces.
DCV is one of the alternative strategies to achieve acceptable indoor air quality with minimum energy consumption.
Current ASHRAE standard 62–2004 requires that the minimum design outdoor ventilation air flow rate should be based on
the occupancy of the space and the area of the space. Measuring directly the actual concentration of pollutants in indoor air is
ideally the best means of controlling indoor air quality. However, it is hard to find one sensor that is able to accurately sense
all the major pollutants at the same time. Even for typical pollutants such as volatile organic compounds (vocs), it is hard to
find an accurate and reliable sensor that is reasonably simple and sufficiently low cost to allow it to be used in online control
applications. Occupancy sensors are widely used in the control of lighting systems.
FEATURES OF AUTOMATION IN HVAC:-
1. Direct digital controls (ddc) let you control your building via the
internet. That means you can take control of your building's system
from practically anywhere in the world.
2. Its controls require fewer personnel to monitor and maintain the
systems. Even if you have a large facility, automated alerts can tell
your personnel when a problem arises. Your system can also use
colored graphs to make it easier for one person to manage.
3. Instead of replacing expensive hardware, most direct digital control
upgrades only need new software.
4. Digital controls offer better accuracy than pneumatic designs. With
better accuracy, you can maintain comfortable temperature levels
throughout a building without losing efficiency.
5. Ddc can improve indoor air quality with demand-based
6. Much easier to change equipment run schedules.
DEVICE , COMPONENT AND APPLICATIONS IN AUTOMATION IN HVAC: -
• Remote controlled automated hvac:-
• The ir (infrared) technology are used in all automated or remote control devices.
• Hvac automation control can run from your ipad, mobile telephone device, stand-alone controller equipment, or
computer whose connection to the hvac units rely on infrared (ir) electronic control technology.
• Technicians can integrate home automation program into the smartphone and mobile phone remote control that works
from a distance.
SENSOR BASED HVAC:-
Thermostats and other types of smart thermostats give you greater control over when your ac is on. These thermostats allow
you to adjust the temperature settings as needed from different locations, so you can raise or lower them when you’re not at
home. For example, you can leave your ac off while you’re at work and turn the thermostat down to get your ac running while
you’re driving home. You can program these thermostats to go on and off at certain times or let them determine when your
home needs cooling by detecting whether or not you’re around.
SMART AIR CONDITIONER IN MARKET USING SMART TECHNOLOGIES:-
1. Ubiquitous sensor network for smart cooling:-
• Developments in the field of electronics, have made the usage of variegated sensors cinch for heavy electrical appliances.
Most of the top ac brands use assorted mix of sensors and sensor technologies to impart smart cooling. Hitachi uses
revolutionary isee technology which comes in the new hitachi models (e.G kashikoi series). These models come with an
intelligent image sensor technology ensure that the users inside the room get an equal attention for an equal cooling
comfort while minimizing the wastage of cooling. The image sensor detects number of people in the room, their location,
their activity etc. And then cools accordingly to ensure maximum cooling comfort
Temperature monitoring and security:- gadgets such as sentri are useful for more than one purpose. These gadgets are able
to monitor the temperature inside your home when you’re away, so you know whether or not your ac should be on. They also
act as a remote security system that allows you to check on your home throughout the day with the help of a built-in camera.
This means you can save money on cooling your home while also making sure everything is safe and sound when you’re not
It also recognizes the shape and size of the room and then regulates its swing angle with a special smart swing
feature in a bid to optimize cooling. Another important feature is it also recognizes human absence in the room
for a specified time and switches the ac off automatically to avoid cooling wastage. Taking cues from hitachi, even
the new daikin acs come with a smart human sensor that detects human presence (and their count) to optimally
cool the room
App control of acs using the smartphone:-
With the growth of smartphone, flurry of apps, millennials want an app for everything; even for controlling
their ac. The ac manufacturers have fulfilled this demand by developing a smart dedicated app to control the ac.
Here too hitachi leads the pack with wifi connect technology which additionally comes with wifi
direct functionality. The user simply needs to download the dedicated hitachi app and pair it with a router. Once
the connection is established, the user can control and monitor their ac from any part of the room. The best part
is, even if router or wifi network is not present, one can still connect the smartphone (even the tablet) with the ac
using wifi direct feature.
Humidity control using auto humid control and dry mode:-
Summer season makes the ac overwork and with the monsoon to follow, ordinary acs could fail to control the
humidity or even result in water leakage. During the rainy season, conventional air conditioners not only consume
more energy but also make the room uncomfortably cold. This may lead to health ailments like sneezing, common
cold or even headache. Most of the new ac models from reputed brands like lg, voltas, bluestar, carrier etc comes
with a dehumidification or dry mode to keep the humidity under control.
LIGHTING CONrOL & ELECTrICAL SYSTEM
A lighting control system is an intelligent
network based lighting control solution that
incorporates communication between various
system inputs and outputs related to lighting
control with the use of one or more central
computing devices. Lighting control systems
are widely used on both indoor and outdoor
lighting of commercial, industrial, and
Lighting control systems are employed to
maximize the energy savings from the
lighting system, satisfy building codes, or
comply with green building and energy
conservation programs. Lighting control
systems are often referred to under the term
In a building, lighting contributes 20-60% of the total consumption of electrical energy usage. To turn on and
off the lamp with the switch manually sometimes people forget to turn it off when leaving the room. This
resulted in the inefficiency of energy and cost, where the lamps work not based on need.
A good lighting design includes a good controls design. Lighting controls play a critical role in lighting
systems, enabling users manually or automatically to:
Turn the lights ON and OFF using a switch;
Adjust light output up and down using a dimmer.
This basic functionality can be used to generate these benefits for the lighting owner:
Flexibility to satisfy user visual needs;
Automation to reduce energy costs and improve sustainability.
In recent years, lighting controls have evolved two additional capabilities:
Adjust light source color, including shade of white light;
Generate data via measuring and/or monitoring.
By adjusting the intensity of one or more layers of
lighting in a space, lighting controls can:
Change space appearance;
Facilitate different functions of the space;
Alter atmosphere and mood;
Increase user satisfaction by providing users the
ability to control their lighting.
By reducing lighting ON time, intensity or zoning, lighting controls
reduce both demand and energy consumption. According to a study,
popular lighting control strategies produce 24-38% average lighting
energy savings, which reduces building operating costs.
Because of strong energy savings, the majority of state commercial
building energy codes require a wide range of controls in new
construction. In existing construction, the controllability of LED lighting
results in an ideal pairing with controls, combining to minimize energy
Various apps and software support implementation of lighting control systems. The most robust software is available for
centralized intelligent networked lighting control systems. Residing on a server or in the Cloud, the software may provide many
functions, such as:
1) Discover Control Points (Devices, Etc.)
2) Assign Control Points To Zones
3) Program Sequences Of Operation For Zones
4) Calibrate Sensors
5) Monitor Control Points And Issue Service Alerts/Alarms
6) Record And Display Energy Use And Other Recorded Data
7) Back Up Data And Event Logs And Create Users/Access Levels
Lighting controls may be categorized as:
3. Standalone sensors/switches
4. Switching or dimming
GENErAL TYpES Of LIGHTING CONTrOLS
Centralized intelligent networked control systems provide
programmable lighting control for entire floors, buildings
or campuses. They may be an extended-feature option of a
room-based control solution or packaged as a
Examples - Relay or Dimming Panels
• Centrally located equipment –
• ease of maintenance
• Straight forward maintenance
• Takes up valuable space in electrical rooms
• Long control wiring runs back to panel
• Less flexibility
Switching or Dimming
• Less space taken in electrical rooms
• Less/shorter wiring requirements
• More flexibility – keeping control in the space it is needed
• Equipment located throughout the building ceiling space, closets, etc
• Newer technology – programming often required for small changes
• Requires costly processor to network distributed equipment
AUTOMATION IN CENTRALIZED AND DISTRIBUTED LIGHTING SYSTEM
• In this design, instead of your high voltage wiring being run to a standard switch or dimmer, is pulled back to a
centralized location in the home. From there it is run directly into your electrical panel and then into something
called a ‘dimmer pack’ within an automation enclosure.
• With all of the lighting loads now handled by the dimmer pack, you eliminate multiple switches in each room and
replace them with a single keypad (or more depending on how many entry points there are into the room) that
communicates to this dimmer pack instead.
• This keypad will be labeled for the various lighting ‘scenes’ for the room – a kids bedroom may only have ‘On’ and
‘Off’ while a Family Room may have additional scenes for ‘Watch TV’, ‘Reading’, ‘Entertain’ that will
automatically adjust the lighting of the room to pre-programmed scenes.
COMPONENTS AND DEVICES :
1. CONTROL KEYPADS - Custom designed lighting scenes
are easily controlled from a variety of keypad styles,

1. GREEN LIGHT POWER PACK (GLPP) - It delivers affordable room lighting
control with essential features for reducing energy usage .Additionally, the GLPP can
be connected to a central control system, enabling it to become an integral part of the
building energy management system.
2. LUMINAIRE CONTROLLERS : The power controller is a relay-based device that
provides ON/OFF switching and (in the majority of LED systems) circuitry enabling 0-
10VDC (and/or potentially DALI) full-range dimming. In a wireless system, the
controller features an embedded wireless receiver that accepts radio control signals
within range. It then acts upon those signals within its set rules.

3. PHOTOELECTRIC SENSOR :
A photoelectric sensor, is an equipment
used to discover the distance, absence, or
presence of an object by using
a light transmitter, often infrared, and
a photoelectric receiver. They are largely
used in industrial manufacturing.

3. STAND ALONE CONTROLS
Standalone controls are control devices designed to provide autonomous operation of a lighting load, which may
be a luminaire or luminaires installed on a switch leg. They typically install on the AC power line and directly
control the load.
Examples: toggle switches, occupancy sensors, timer switches, dimmers, light sensors and hotel keycard
Occupancy sensors, daylight sensors, local dimmers & switches.
AUTOMATION IN STANDALONE LIGHTING SYSTEM
COMPONENTS AND DEVICES :
1. STANDALONE EMBEDDED SENSORS
Standalone occupancy and light sensors may be
mounted in or attached to luminaires for autonomous
luminaire control. Typically, sensors are specified via
the luminaire manufacturer and installed at the
factory. However, they may be specified from a
control manufacturer for relatively simple field
attachment. The controls may offer options such as
dimming or switching to a lower light level during
vacancy instead of turning OFF. If the luminaires dim
instead of shut OFF, additional scheduling control
may be needed to provide energy code-compliant
The major advantage of a lighting control system over stand-
alone lighting controls is the ability to control individual lights
or groups of lights from a single user interface device.
STANDALONE EMBEDDED SENSORS
FAWS, the switch allows you to adjust the luminaires wattage and light output in the field
using ten preset positions. Optional Field Adjustable Wattage Selector (FAWS) switch can be
operated even while earing Lineman’s gloves, providing tactile, audible and visual switch
• Helps keeping a lower luminaire variety in inventory by been able to adjust luminaire to
desired wattage at the onsite installation
• Provide flexibility for onsite last second adjustment vs photometry
• Include an auxiliary position option for future control system retro-fit
OccuSwitch wall switch and low voltage occupancy sensors automatically turn lights off
when a work space is unoccupied, saving energy and creating a more sustainable work
environment. The ceiling mounted sensor communicates with a network of wall switches
and dimmers. Using a combination of ultrasonic and passive infrared (PIR) technology,
the sensor recognizes room occupancy or vacancy for maximum performance and energy

SITEWISE AREA LIGHTING
Types of Lighting Controls
Light dimmers do exactly what their name states, they dim light.
These switches allow for more control than just on and off. With
the ability to decrease brightness, dimmers reduce wattage and
output, which saves energy and lowers cost.
Pros: Reduces energy consumption, allows for control over
Cons: Can potentially reduce a light bulb’s efficiency
2.Motion Sensor Lighting
Motion sensor lighting controls turn off and on by the detection
of movement. They can be installed indoors, but are particularly
useful in outdoor locations to light up areas at night. They, too,
are energy efficient by eliminating accidentally leaving the
lights on completely. Plus, no one wastes any time trying to find
the light switch in a dark room. Sensor lighting controls use
body heat and wavelengths so they’re extremely reliable, as
Pros: Energy efficient, easy to use, saves time.
Cons: Little control, unwanted shutoff if motion isn’t detected,
don’t work well with certain bulbs.
Lighting timer controls are programmable light switches.
They can be set so that lights are turned on only during a
certain period of time. They are helpful in regulating energy
consumption also but just make scheduling easier for your
home or building. There are two types of timer lighting
controls, manual and in-wall programmable digital timers.
Pros: Increase energy efficiency, good for scheduling.
Cons: Aren’t great to use outdoors because of seasonal
changes, may require particular bulbs and lamps.
• INTELLIGENT LIGHTING CONTROL SYSTEMS include multiple technical solutions and features that automatically
regulate different parameters for lighting, such as the intensity and the colour temperature of the light.
• These are formed by Active Dimming, Light Colour Temperature, and RGB Control Systems that guarantee the cost-
effectiveness , reliability and pleasant interior lighting with a range of moods.
ACTIVE DIMMING SYSTEM
The control unit for the Active Dimming is an Intelligent
Lighting Control System that uses sensors to adjust the interior
lighting o based on exterior light conditions. The control unit
can be set for minimal lighting requirements, in which case the
desired lighting level is obtained by the optimal use of the
lights, that is, with minimal energy consumption. This
significantly reduces the lifecycle costs of lighting.
LIGHT COLOUR TEMPERATURE CONTROL
This Intelligent Lighting Control System improves comfort level by adjusting the
colour temperature of the interior light. The different tones of the light have a
significant biological impact on human activities and feelings. On a hot summer day, a
cool white light creates a sense of cooler atmosphere, while a warm white light creates
a feeling of warmth.
These are small electronic eyes that detect infrared waves—heat waves that
radiate from moving objects. ... The motion sensing light stays on anywhere
from 1 to 20 minutes, depending on how you preset the timer. Then
the detector automatically shuts the light off unless it continues to
There are many motion detector and motion sensor light styles to choose
Three common types are:
Motion activated flood light
The different tones of RGB-LED lights can
achieve striking effects, or they can change the
atmosphere of the illumination as needed. In
an RGB-LED Intelligent Lighting Control
System, components emitting red, green, and
blue light are all in one LED. The brightness
of the components can be adjusted separately,
making it possible to create nearly all color
TYPES OF LIGHTING:
Also known as background or
ambient lighting creates a soft glow
that gently illuminates an area without
causing glare. Light fixtures such as
upward facing wall lights can be
effective at creating ambient lighting.
ACCENT LIGHTING OR
This type of lighting is used to provide
texture and focus to general lighting,
and can draw attention to items on
display such as artwork, while
shadowing other areas.
Accent lighting might be provided by
table lamps landscape lighting, and so
EMERGENCY LIGHTING OR SAFETY LIGHTING.
Emergency lighting is installed to provide lighting in
the event of mains power failure and provides
sufficient illumination to allow occupants of
a building to evacuate safely. Types of emergency
lighting include; emergency exit signs, recessed
fluorescent lights, powerful halogen emergency
spotlights for larger spaces,
emergency ceiling lights and downlights, and so on.
Security lighting is generally used to illuminate
an area where there is a concern for security. This may be
turned on throughout the hours of darkness, to give
visibility of an insecure area, or it may be turned on
temporarily, for example when a person arrives at
a property, sometimes activated by a linked detector
LIGHTING FOR CIRCADIAN RHYTHMS
Circadian rhythms are physical, mental, and behavioral changes that
follow a daily cycle.
A combination of bright light during the day and darkness at night helps
maintain the daily cycle of waking and sleep. Circadian lighting varies
in cooler and intensity during the day. The aim is to improve alertness
during working hours using bright light, but to switch to lower
brightness, warmer colored light before it is time to relax.

turn on the flow of water when it detects movement in the sink,
and turn off once your hands have been removed.
• WCs account for nearly 30 percent of
an average home’s indoor water
consumption. Older toilets use as much
as 6 gallons per flush. But the newer,
EPA Water Sense-certified toilets use
just 1.28 to 1.6 gallons of water per
flush. Dual-flush toilets use even less

WATEr CONSErvATION TECHNOLOGIES AND STrATEGIES
Water efficiency is the planned management of water to prevent waste, overuse, and exploitation of the resource. Effective
water efficiency planning seeks to "do more with less" without sacrificing comfort or performance.
WATER CONSERVATION STRATEGIES
There are a number of strategies that can be employed to reduce the amount of water consumed at a facility. In general terms,
these methods include:
System optimization (i.e., efficient water systems design, leak detection, and repair);
Water conservation measures; and
Water reuse/recycling systems.
Water-efficient plumbing fixtures (ultra low-flow toilets and urinals, waterless urinals, low-flow and sensored sinks, low-
flow showerheads, and water-efficient dishwashers and washing machines)
Irrigation and landscaping measures (water-efficient irrigation systems, irrigation control systems, low-flow sprinkler
heads, water-efficient scheduling practices, and Xeriscape)
Water recycling or reuse measures (Grey water and process recycling systems), and
Methods to reduce water use in HVAC systems.
1. PUBLIC INFORMATION AND EDUCATION
The following bullets summarize some of the
activities that can be incorporated into a public
information and education program:
Establish hot line or other reporting mechanisms
to report leaks and waste;
Place signs on new equipment on how to use;
Initiate a suggestion or incentive program;
BEST MANAGEMENT PRACTICES
Distribute flyers and pamphlets to increase awareness
of the facility's water management plan and educate
inhabitants on wise water use practices; and
Develop a display on water management highlighting
the practices in use at the facility (i.e., Xeriscape, ULF
toilets, water reuse, etc.) and its resultant savings and
benefits and place in a highly visible area of the
2. DISTRIBUTION SYSTEM AUDITS, LEAK DETECTION, AND REPAIR
Performance of a water distribution system audit is not limited to existing, aged buildings. Water system leaks can occur in
new construction from improper installation of piping and fixtures, or impacts to piping systems during the construction
process. Water system leaks that are not repaired immediately can damage building structures, since even a small leak can
result in the loss of large quantities of water over time. With un-metered service, leaks go undetected; water is wasted; and
there is no accountability and therefore, no incentive to save.
3. WATER-EFFICIENT LANDSCAPING
Landscaping water usage can easily account for 20% or more of facility water
consumption, and is a key area to target for water use savings. There are three major
components to designing a water-efficient landscape for a new facility:
1) reduce the amount of turf and other irrigated areas
2) ensure water-efficient design of irrigation systems,
specify native or climate appropriate landscape materials (Xeriscape). Reducing the amount of turf grass and overall
irrigated areas will reduce water consumption and associated costs, and will result in time and dollar savings from mowing,
fertilizing, waste removal, and maintenance.
Remaining landscape areas that require irrigation should utilize water-efficient irrigation systems (low-flow sprinkler heads,
efficient system design and layout, and optimized irrigation schedules and controls) to minimize water use and maximize
plant health. Utilizing Xeriscape strategies whenever practicable will save on water, fertilizer, pruning, maintenance, labour,
and overall costs.
4. TOILETS AND URINALS
Toilet and urinal flushing typically account for nearly one-third of a building's total water consumption, and
this end-use is one of the simplest and lowest cost areas to target for significant water and sewer savings.
ULF urinal products are typically offered in four categories: 1) symphonics jet, 2) washout and washdown, 3)
blowout, and 4) waterless,
Waterless urinals have gained widespread acceptance, as they are made of a urine-repellent surface; have no
flush handles or moving parts; and virtually require no water.
Additional savings in the area of toilets and urinals can be achieved by utilizing non-potable water for flushing,
or utilizing composting or incinerator toilets where sewer service is not available.
5. SHOWERHEADS AND FAUCETS
Federal legislation passed in 1992 (EPAct) requires that all U.S. plumbing manufacturers and importers meet or beat the
following water-efficiency standards for new fixtures: showerheads—2.5 gallons per minute; and faucets—2.5 gallons per
Newer models and features of these low-flow showerheads include:
1) atomizers that deliver water in small but abundant droplets that cover larger surface areas,
2) pulsators that vary spray patterns with pauses between spurts or through pulsating between strong flow and light mist, and
3) aerators which mix water droplets with air to cover the desired surface area.
4) Low-flow faucets also employ the use of aeration technology, as well as sensors, to achieve water savings at equivalent
comfort levels to older, more consumptive fixtures.
Examples of newer low-flow faucet technologies include:
1. metered valve faucets that deliver a preset amount of water and then automatically shut off (the federal standard for this
fixture type is 0.25 gallons per cycle);
2. self-closing faucets that are spring-loaded to shut off the faucet a few seconds after the user turns it on, and
3. ultrasonic and infrared sensor faucets that automatically activate the faucet when hands are detected beneath it, and
automatically shuts off the water when the hands are removed.
6. COOLING TOWER MANAGEMENT
Cooling towers assist in regulating indoor air temperature of a building by either rejecting heat from air-conditioning systems
or by cooling hot equipment, and require vast amounts of water to perform these functions. To replace this lost water more
make-up water must be added. To displace the use of potable water used in cooling towers, sometimes water used for other
purposes within a facility can be recycled and reused as make-up water with little or no pre-treatment, including:
water used in a once-through cooling system,
pre-treated effluent from other processes, provided that any chemicals used are compatible with the cooling tower system,
high-quality municipal wastewater effluent or recycled water (where available).
Additional measures that improve the efficient utilization of water in cooling towers include:
Installing a side stream filtration system composed of a rapid sand filter or high-efficiency cartridge filter to cleanse the
water. These systems draw water from the sump, filter out sediment, and return the filtered water to the tower, enabling the
system to operate more efficiently with less water and chemicals.
Installing covers to block sunlight penetration and inhibit algae growth
Installing automated chemical feed systems on large cooling tower systems (over 100 tons). These systems minimize water
and chemical use while optimizing control against scale, corrosion, and biological growth.
7. SINGLE-PASS COOLING EQUIPMENT
Single-pass, or "once-through", cooling equipment circulates water one time through a piece of equipment to cool it, then the
water is discharged (often to the sewer line).
Single pass cooling equipment is often specified for such end-uses as: CAT scanners, degreasers, hydraulic equipment,
condensers, air compressors, welding machines, vacuum pumps, ice machines, x-ray equipment and air conditioners.
Using water for only one cycle and then discharging it results in significant waste, and this process can be avoided in many
instances. Strategies to reduce waste from single-pass cooling include:
specifying multi-pass, closed loop, or air-cooled equipment options (note that some equipment types may not function
properly if other than single-pass is specified, be sure to check with equipment manufacturer first) to arrive at the most
water- and energy-efficient cooling system,
specify an automatic shut-off valve to the cooling system to eliminate usage
when equipment is not running (to be used only on equipment where indoor air
quality is not a concern), and
find alternative uses for single-pass effluent such as landscaping, boiler or
cooling tower make-up water, toilet flushing, etc. (ensure that effluent does not
contain any waste stream such grease or chemical agents).
8. BOILERS AND STEAM SYSTEMS
Boilers and steam generators are used in large heating systems, institutional kitchens, and in facilities that require large
amounts of processed steam. Many of these systems use large amounts of water to make hot water and/or steam that is then
subject to losses from leaks and "blow-down".
Strategies to achieve water and cost savings from boiler and steam systems are highly site specific, but may include:
9. MISCELLANEOUS HIGH WATER-USING PROCESSES
Numerous site-specific processes requiring high water use are found within federal facilities. These processes and/or end uses
include kitchens and food processing, vehicle washing stations, laboratory uses, cleaning/laundry facilities, fish hatcheries,
treasury production, and more. Each of these end uses and their application within federal facilities presents site-specific
opportunities and challenges for reducing water usage. For new facility design, each high water-using process should be
identified and estimated usage quantified—and then reviewed and analysed for potential energy and water savings measures.
Some processes may require outside expert assistance to identify the most applicable and beneficial water savings options.
properly sizing boiler and steam units (and possibly downsizing units by reducing facility
heat and steam requirements—and thus reducing makeup water requirements),
specifying the most life-cycle cost-effective system option, and not just the lowest first cost
installing a small summer boiler or distributed system for reheat or dehumidification
requirements instead of inefficiently running a large boiler at part load, and
considering alternative technologies such as heat pumps for small loads.
10. WATER REUSE AND RECYCLING
The use of non-potable water resources is often more cost-effective if applicable end-uses are identified early on in the
building design process. There are four general strategies that can be employed for utilizing reused or recycled water.
1. On-site water reuse or recycling: this process relies on reusing water from the same purpose at the same location, and
usually involves minimal treatment or filtration to make it acceptable for its intended reuse. Examples include rinse water
that is filtered from car washing and laundry uses and then used in the next wash cycle.
2. Reclaimed/treated water: this non-potable water resource is developed by treating used water to wastewater treatment
standards and then redistributed for on-site use. This strategy can be costly, but may still be cost-effective due to offsets of
potable water purchases and sewerage costs. Non-potable water meeting wastewater treatment standards can be used for
end uses such as landscape irrigation, decorative fountains, cooling tower makeup water, toilet flushing, fire sprinkler
systems, and other on-site industrial processes.
3. Grey water: this resource is derived from water captured from uses such as showers, baths, sinks, and laundries
(excluding diaper washing and food processing) and then filtered to remove solids. Grey water may be used to serve such
end uses as landscape irrigation (preferably subsurface) and toilet flushing.
4. Water catchment systems: this resource includes non-potable water captured from rainwater sources or from rivers,
lakes, ponds, and wells that have not been treated to meet potable standards. Rooftop rainwater collection systems are
becoming increasingly popular, and the captured water can be stored in architecturally aesthetic cisterns. End uses that can
be served by this resource include landscape irrigation, single pass cooling, and toilet flushing.

waiting for the temperature to change.
• This clean water can then be used in the kitchen or outdoors.
• Using defrost water from refrigerator.
• Saving water from air conditioner
• Consider investing in weather-based irrigation controllers that
adjust to real weather conditions and provide water only when
• Replace older mist-style sprinkler heads with today’s newer,
and more efficient, rotator sprinkler heads, which shoot jets of
waters at a slow rate to increase penetration and eliminate drift.
• This application rate allows up to 30% less water use when
compared to traditional sprays

Elevator is a type of vertical transport equipment that efficiently moves people or goods between floors (levels, decks) of a
building, vessel or other structures. Elevators are generally powered by electric motors that either drive traction cables or
counterweight systems like a hoist, or pump hydraulic fluid to raise a cylindrical piston like a jack.
