2. The House
This house located in _________ is a very energy efficient home,
able to accommodate a family of four. With 10 rooms and
energy efficient appliances included
This house is designed to have no air conditioning built in it
Since it utilizes venetian blinds instead. These blinds keep air
Flowing in and out of it, and when it gets to cold, air circulation
Can be managed by closing or opening the blinds.
3. Energy Efficient
appliances list
The Haiku Big Ass Fan ( B-A-F) model K3150-S1 is a large energy
efficient air circulator that operates at an amazing15W.Compared
to the leading general house fan that uses 70 watts. It is placed at
the center of the house for maximum air circulation, resulting in a
much cooler and manageable air space for the whole family.
This fan should be used during the hotter times in the day from 12
PM to 6 PM.
This energy efficient house has 10 LED lights with one in each
room. Operating at 0.0077 Kilo Watts per hour each, it’s
brightness is enough to illuminate the rooms during the night
time without using the normal 0.07 kilo watts per hour that a
normal light bulb does. This light bulb is used four hours a day
between 6 PM to 10 PM.
The Samsung WF461 doubles as both a Washer and a
Dryer. This energy efficient appliance enables the user to
steam dry and wash their clothes with both warm and cold
water at a low wattage usage of 250 compared to the
normal 800 watts used by the leading washer and the
other 600 watts for the dryer. Although you probably wont
use it everyday, this appliance is available for use every
day from 7PM to 8PM
4. The Magnavox 22ME601B/F7 is an energy efficient LED TV.
The family can enjoy the quality HD TV experience by using only
0.0154 kilowatts per hour compared to the wasteful 0.45 kilowatts
per hour that a regular TV uses. This TV is available for use 6 hours
a day from 2 PM to 10 PM.
The PlayStation 3 is a versatile item since it doubles as
a gaming system , and a Blu Ray DVD player for .21
Kilo Watts per hour, Instead of buying a separate DVD
player that will take up an extra 60 watts of energy.
This item is available for use for one hour a day from
7PM to 8PM.
The Zeo Sleep Manager is an energy efficient alarm clock
that keeps time and wakes the whole family up for only 6
watts compared to the usual 14 watts
That a usual alarm clock uses for the amount of noise the
Zeo Sleep Manager generates. This alarm clock is on 24
hours a day so the family will have a clock to watch time
for them.
5. This General Electric refrigerator model works
for 16 hours with an amazing energy usage of
52 watts, compared to the usual 320 watts that
a regular refrigerator has. This refrigerator is on
from 4Am to 10 PM everyday.
The Roswell 1500 induction stove is a very energy
efficient stove that can heat up a liter of water in
less than three minutes using only its 3rd setting. This
model features 11 energy settings but is best used
with setting 5 or lower. It works with Magnetism , so it
will only heat metals, this works as a safety system
for children, just in case they touch the stove, they
wont get burned from the heat.
The Mandalay wind water heater is an energy efficient
600 watt water heater that is able to heat 20 gallons of
water in one hour. This water heater is separate from the
water container. Which will also be provided with a size for
20 gallons of water. The water heater Is on 1 hour a day
from 5AM to 6AM
6. The Panasonic KX-
TGA101S Digital Cordless
Handset is an energy star
product that calls and
receives for 2.5 watts. The
system is on 24 hours a
day in order for the family
to not get any missed
calls.
7. The Safeguards
Timer switches are a relatively simple and inexpensive solution to the
problem of forgetting to turn an appliance off. At a time when
everyone is looking for ways to go green, timer switches are an excellent
example of green automation. Timer switches are simple in concept;
after a certain time period has elapsed the light turns off. How often do
you go to the basement and forget to turn the light out when you come
back upstairs? A better question: How often do your children do that? A
timer switch automatically turns off its load after a preset time. The
amount of time depends on the switch and its options. Some switches
have one preset time (15 minutes is common) while others allow you to
set the delay before the timer shuts down.
While timer switches are relatively common and available from a variety
of manufacturers, ones that work with a home automation system are
harder to find. Perhaps the only widely available automation timer
product is the INSTEON SwitchLinc Timer from Smarthome.
Each appliance in our energy efficient house is equipped with these.
These devices are pre-set so that your appliances will never stay on
longer than they should.
8. How the Solar Panel Works
Solar panels work by converting the photons (particles of
light) that the sun emits into electrons of direct current (DC)
electricity. These electrons flow out of the panel into an
inverter and other electrical safety devices. The inverter then
transfers the DC power into alternating current (AC)
power, that powers the devices we plug into the walls of our
homes. When you have extra power that is not used right
when you get it from the solar panels it will be stored for a
day that is not so sunny.
9. AC/DC currents
Electricity is a type of energy that involves movement of
electrons along conductors, such as a wire, in either one or
two directions. When the electrons are flowing in one
direction only it is called a direct current or DC, and when it
is flowing in two directions it is called alternating current or
AC. DC is produced by batteries and electrical power grids
that provide electricity to homes and other building create
AC.
10. Voltage, and how it is affected
by AC/DC currents
Voltage, otherwise known as electrical potential
difference or electric tension is the difference in
electric potential energy per unit charge between
two points. Voltage is equal to the work which would
have to be done, per unit charge, against a static
electric field to move the charge between two
points. Voltage may represent lost or stored energy
or a source of energy.
Voltage is affected by the type of current a person is
using. in DC the voltage produced is one and doesn't
travel very far before it begins to lose energy. In AC
the voltage produced can be raised or lowered in
strength by another mechanism called a transformer.
11. Electric circuits and the differences between
series and parallel
Electrical circuits are paths in which electrons from a voltage or current source
follow. Electrical currents flow in closed paths called electrical circuits.
Electrical circuits can be either parallel or series circuits. some of the difference
between series and parallel circuits are that the voltage drop at each
component (the amount of volts the device receives) are the same in series
but usually different in parallel, the is a slight rise in current for the parallel, and
the equations for finding the current and voltage drops in each component is
different.
12. Circuit Breakers
A circuit breaker is an automatic safety
switch that is designed to protect the
electrical circuit from damage caused
by overload, overheating, and short
circuit. Circuit breakers work by
detecting a fault or problem in the
circuit that can cause damage and
then opening the circuit to stop the flow
of energy.
13. Electric System Limitations
In the house, you will be able to have a maximum amount of 2400 watts
of appliances on at any given time before the circuit breakers flip and
shut off the power.
Every day you will only be able to use about 3k watts per day and 90k
watts every 30 days.
Going over 30k watts per 30 days will result in no electricity, until the next
30 days
Kw = measurement of power
Kwh =measurement of energy
Watts = unit of power or rate of energy use
Energy : Energy is a measure of how much fuel is used by
something over a specific period of time.
Power : Power is the rate at which energy is generated or used.
