Green Buildings are buildings with increased
efficiency in the use of ;
• Energy
• Water
• Materials
while reducing the impact of construction or operational activities on
human health and the environment through better siting, design,
construction, operation, maintenance, renovation and demolition.
4. IMPACT OF CONSTRUCTION AND THE BUILT
ENVIROMENT
Around half of all non-renewable resources mankind consumes are used in construction,
making it one of the least sustainable industries in the world. – WILLMOT DIXON

KEY FINDINGS : GLOBAL TRENDS
Increased adoption of greener business
practices by facility managers and real
estate consultants.
Globalization is reinforcing and accelerating
sustainable property developments and
operating trends.
Major corporate clients are seeking greener
facilities in a bid to attract and retain
workers, differentiate their product ,
improve their image to consumers and
satisfy stakeholders .
Greener business practices are being
driven by increasingly prescriptive
government regulations.
12. THE GREEN EVOLUTION : NIGERIA
Energy Supply ; Very low .An average of 40million litres of
petrol/diesel per day is used in Nigeria for private generation
of electricity.
Transportation ; Poor state of infrastructure and lack of
impactful investments hence a lack of efficient transportation
systems
Waste Management ; Environmentally sustainable waste
disposal is still very low in most states in Nigeria with the
exception of Lagos state which has a fully implemented
waste management strategy.
Design and Building Innovation ; The government is yet to
introduce policies and champion the implementation of green
buildings in Nigeria. Private sector buy in still low.
Information: There is relatively little information about Green
building technology and materials in Nigeria.
13. FACTORS INHIBITING THE DEVELOPMENT OF GREEN
BUILDINGS IN NIGERIA
Lack of institutions to formulate policies and set guide lines.
Lack of information about green products and high performance
building systems
Human resource and client knowledge
Low level expertise
Low level of awareness with regard to sustainability issues
15. GREEN BUILDING RATING SYSTEMS
The definition of a “green” building is often in the eye of the beholder.
Rating or certifying a green building helps to remove that subjectivity.
Several rating systems have evolved over the years. The most popular ones
include :
BEREEAM (Building research establishment’s environment
Assessment Method)
CASBEE (Comprehensive assessment system for building
environmental efficiency)
SBTool (Sustainable building tool)
Green Globes
LEED (Leadership in energy and environmental design)
16. GREEN BUILDINGS CERTIFICATION : LEED
The LEED Green Building Rating Systems are voluntary,
consensus-based, and market-driven.

20. SUSTAINABLE SITES
SUSTAINABLE SITES
Issues
The built environment has
tremendous impact on
natural resources and the
Immediate environment.
These issues relate to
Hardscape, Lamdscape,
exterior building management
21. SITES: SUSTAINABLE FM PARACTICES
• Minimise the use of fossil fuel driven equipment for
the management of building landscape. Use of battery
driven/electric driven low noise equipment for cleaning
pavements, mowing, lawns, clean walkways and the
likes.
• The use of biodegradable/low impact chemicals used
for cleaning of building facades, low VOC paints.
• Diversion of landscape waste from waste stream by
composting to act as storm water control.
• Minimizing the use of chemical fertilizers
• Planting sustainable landscape
23. • Installation of meters to monitor the level
of water consumption within the building
and site
• Installation of flow restrictors or reduced
flow aerators on Faucets /showers.
• Replacement of portable/treated water
usage with captured rain water for
irrigation and washing of vehicles.
• Practice water efficient landscaping :
Drip Irrigation, Xericulture.
WATER EFFICIENCY : SUSTAINABLE FM PRACTICES
24. ENERGY AND ATMOSPHERE
24
ISSUES:
Building consume a lot of energy.
Generating electricity from fossil fuels
such as diesel, natural gas and petrol,
negatively affects the environment.
Green buildings address the issues in two
ways.
First, they reduce the amount of energy
required to operate a building, and
Second, they use more benign forms of
energy.
The release of chlorofluorocarbons
(CFCs) from Air Conditioning and
refrigeration equipment destroys ozone
molecules .
25. • Conduct energy surveys and audits for building,
identify areas responsible for over 10% energy
consumption and put in place plan to reduce
energy consumptions in those areas
• Conducting systems commissioning ,retro
commissioning and Ongoing commisioning
(Maximum 24 Months commisioning cycle)
• Right size major equipments / Plants (HVAC,
Generators etc)
• Exploring onsite/offsite renewable energy
(Solar, Wind etc)
• Building Automation Systems
• Phase out the use of CFCs in Air conditioning
system (Montreal Protocol phase out of CFC
2010)
ENERGY AND ATMOSPHERE: SUSTAINABLE FM
PRACTICES
26. INDOOR ENVIRONMENTAL QUALITY
26
ISSUES:
We spend over 75% of out time
indoors , and the quality of the
indoor environment therefore has
a significant influence on well-
being, productivity and quality of
life.
U.S. Environmental Protection
Agency (the EPA) reports indoor
air pollution as a top
environmental risk to public
health.
27. Maintain adequate ventilation ; Minimum 10cubic ft (0.3 cu.m) of outdoor
ventilation per person . All AHU must be tested regularly to ensure
standards are met.
Environmental Tobacco Smoke : Prohibit smoking in the building by
instituting an ETS policy. Create designated smoking areas outside the
building away from ventilation system and away from concentrations of
building occupants or pedestrian traffic.
If it is not feasible to prohibit smoking indoors, design designated
smoking areas that isolate and control ETS from entering other areas
of the building. A separate ventilation system must be installed and
tested to ensure that the smoking areasare isolated from nonsmoking
portions of the building, and a negative pressure (compared with
surrounding spaces) must be maintained in these areas.
Green cleaning practices: Purchase sustainable cleaning and hard floor
and carpet care products . Purchase cleaning equipment meeting the
sustainability criteria . Develop guidelines addressing the safe handling and
storage of cleaning chemicals . Staffing and training of maintenance
personnel
Implementation of integrated pest management
INDOOR ENVIRONMENTAL QUALITY: SUSTAINABLE
FM PRACTICES
28. MATERIALS AND RESOURCES
ISSUES:
Building operations generate a
large amount of waste on a daily
basis
There is a need to reduce the
environmental impact of materials
brought into the project building
and the minimization of landfill
and incinerator disposal for
materials taken out of the
building.
29. Sustainable purchasing : Source reduction, waste
prevention, and reuse practices will help reduce
consumption of virgin materials and mitigate the
negative environmental impacts of materials use.
Reduced amount of mercury brought into the
building through lamps : Mercury causes serious
ecological and human health problems when
released to the environment through human
activities. Low mecury, High Output (Lumens),
Longer Life
Reduce, Reuse, Recycle
MATERIALS AND RESOURCES: GREEN PRACTICES

CONCLUSION
The concept embodies the entire life cycle of a building.
Not an assemblage of “environmental” components or a piecemeal modification of an already-designed, standard building.
These approaches not only add to the building’s cost, but also produce marginal resource savings at best.
Considers a holistic approach.
Capture synergies across systems through integrative design and construction
Should be considered as early as schematic designs
Consider Green Building Systems and Green Building
The issue
Triple bottom line is also often used to refer to the concept of sustainability.
PEOPLE (social capital):All the costs and benefits to the people who design, construct, live in, work in, and constitute the local community and are influenced, directly or indirectly, by a project
PROFIT (economic capital): All the economic costs and benefits of a project for all the stakeholders (not just the project owner)
PLANET (natural capital): All the costs and benefits of a project on the natural environment, locally and globally
BEREEAM(Building Research Establishment’s Environmental Assessment Method) has a long track record in the United Kingdom however it is difficult to obtain current information about the system as it is not publicly available for purchase and can be purchased only through licensed assessors.
CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) Japan is a relatively new system developed for the Japanese market that is available in English. It is structured to award high assessments to superior buildings. It is simple to use and suits issues that affect Japan and Asia.
Green Globes™ Canada and US was adapted from Green Globes Canada in 2004. This is a developing tool that addresses major renovation, tenant build-out, operations and maintenance applications.
LEED( Leadership in Energy and Environmental Design) is currently the dominant system in the United States market and is being adapted to multiple markets worldwide
When reservoir water levels get lower and ground water tables drop, water supplies, human health, and the environment are put at serious risk.
Gardens, landscapes, etc. that require a small amount of water
Drip irrigation, also known as trickle irrigation or micro irrigation or localized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant.
Generating electricity from fossil fuels such as diesel, natural gas and petrol, negatively affects the environment. at each step of production
and use, beginning with extraction and transportation, followed by refining and distribution, and
ending with consumption.
The release of chlorofluorocarbons (CFCs) from Air Conditioning and refrigeration equipment destroys ozone molecules .
in the stratosphere through a catalytic process and harms the planet’s natural shield for incoming
ultraviolet radiation. CFCs in the stratosphere also absorb infrared radiation and create chlorine,
a potent greenhouse gas. Banning the use of CFCs in refrigerants slows the depletion of the ozone
layer and mitigates climate change.
The designated smoking
areas must be clearly defined: An entire space, such as a restaurant, cannot be defined as a smoking
area. A separate ventilation system must be installed and tested to ensure that the smoking areas
are isolated from nonsmoking portions of the building, and a negative pressure (compared with
surrounding spaces) must be maintained in these areas. Following the testing procedures outlined
According to the Whole Building Design Guide, over a 30-year period initial building costs typically account for only two percent of the total, while operations and maintenance costs equal six percent
