Sustainability & public policy Survey report on water and energy use in home or apartment. Report the household water Use (gal. per day) for total water use, outer door use and indoor use. There is a comparison, but they all use 80-100 liters of water a day. It is any wonder that most of the water is a rock of water and it gets into the water. So we began to see the water table and the water today, like water. Most of the local governments now have water, hospitals and water, which threaten every minute for every minute. In some areas, Georgia's Atlanta has no home. In fact, I put two new clothes and I get $ 100 to one. Yes, they use water. For your kitchen and bathroom, if you look directly to the head, you will see something like "1.0 GPM", which means a bush. More than 1.0 water per day.

Total need of water per person is 150 Gallons per day. So total use of water for 6 people is 150*6=900 Gallon per day.

Report your Hot water Use (gal) per day. How many thermos of natural gas per year are required? What is estimate cost? The sum of the hot water needed 20 percent of the water used in the house. The hot water company is 900 gallons per day = 20/100 180 * 8.33 gallons of water weighs pounds. If you want to increase the incoming water to 140 F at 60 ° C and 80 ° C, which is an increase, if necessary cold water liter and 667 x 8.33 = 80 BTU, with an efficiency of 100%. A typical water heater tank is only 59% efficient. It takes 667

59% = 1131 BTU in hot water around a

gallon of gas. A 1 BTU is Thermo 100,000. A BTU is a BTU thermos 1131 thermos 0.00001 0.0113. They required a 0.0113 thermos to about a gallon of cold water, or 0.0113 x 2.04 = 180. Coolers to heat a year, 2:04 = 365 * 742 Thermos. For $ 1.20 / $ 1.20 = $ 742 x thermometer takes 890 heat for the year .Report the Greenhouse gas Emission /carbon footprint (lbs. CO2 equip per year) how many acres of forest are required to absorb your carbon foot print. The carbon dioxide per thermos is 21.1 lbs. so the total co emits 742*21.1 =15656lbs

Table 1 Average CO2 emitted from different fuel. 2

A single tree can absorb CO2 at a rate of 48 lb. per year. So the total no trees to absorbed CO2 is 350 tree approximately which required 7 acres of land. Compare your values against the national efficient home and national average. Our house use is the produced 159.8 kwh. so it becomes in B categories which according to efficient home that required between 125-200 kw/h energy per year. The national average of house consuming is 800kwh per year for heating water. Review and suggestion and summary section of this module. Passive residential buildings save up to 90% heat and cooling associated with a standard building flag and are 75% more common than building construction. When oil is turned, non-residential buildings usually use 1.5 liters per square meter per year compared to low-power buildings. In warmer seasons, buildings have harder energy savings to make heating warmer. Housing properties are also assessed as appropriate. They are very easy to use, for example heat sources, such as buildings or heat, to use internal energy sources within the building. Windows keeps winter and is kept in summer with good, well-wrapped equipment and cover of mainly walled walls, tiles and slabs. The ventilation system always provides good air quality for new unused air. This is a low blood pressure and low blood guarantee. There is an efficient heat pump to allow the air to recover.
