Energy efficient home

  1. 1. Energy Efficient Home
  2. 2. The HouseThis house located in _________ is a very energy efficient home,able to accommodate a family of four. With 10 rooms andenergy efficient appliances includedThis house is designed to have no air conditioning built in itSince it utilizes venetian blinds instead. These blinds keep airFlowing in and out of it, and when it gets to cold, air circulationCan be managed by closing or opening the blinds.
  3. 3. Energy Efficientappliances 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. 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 asa gaming system , and a Blu Ray DVD player for .21Kilo Watts per hour, Instead of buying a separate DVDplayer that will take up an extra 60 watts of energy.This item is available for use for one hour a day from7PM 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. 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 energyefficient stove that can heat up a liter of water inless than three minutes using only its 3rd setting. Thismodel features 11 energy settings but is best usedwith setting 5 or lower. It works with Magnetism , so itwill only heat metals, this works as a safety systemfor children, just in case they touch the stove, theywont 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. 6. The Panasonic KX-TGA101S Digital CordlessHandset is an energy starproduct that calls andreceives for 2.5 watts. Thesystem is on 24 hours aday in order for the familyto not get any missedcalls.
  7. 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. 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. 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. 10. Voltage, and how it is affectedby 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 doesnt 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. 11. Electric circuits and the differences between series and parallelElectrical circuits are paths in which electrons from a voltage or current sourcefollow. Electrical currents flow in closed paths called electrical circuits.Electrical circuits can be either parallel or series circuits. some of the differencebetween series and parallel circuits are that the voltage drop at eachcomponent (the amount of volts the device receives) are the same in seriesbut usually different in parallel, the is a slight rise in current for the parallel, andthe equations for finding the current and voltage drops in each component isdifferent.
  12. 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. 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.
