6. 13 Conservation
Conservation & Energy Efficiency Conservation: Find and implement ways to use less energy Energy efficiency: Do same work for less amount of energy
Governmental Conservation Measures 1. Improve/increase public transportation 2. Tax use of oil, electricity, and natural gas 3. Offer rebates/tax credits for retrofitting
Tiered Rate System: Customers pay a low rate for the first increment and pay more as use goes up
Peak Demand: Certain times of the day or year when prices are higher Systems must be prepared for the maximum demand or brownouts can occur
Energy Star math You are buying an air conditioner. The Energy Star brand is $300 and the standard is $200. They have the same cooling capacity, but the Energy Star costs 5 cents/hour less to run. If you run it 12 hours a day, how long does it take to recover the cost? 5 cents/hr x 12 hr/day = $0. 60/day in savings $100/$0. 60/day = 167 days
Now you want to buy a nice flatscreen. Electricity costs $0. 15/k. Wh. You watch 4 hours a day. (This is too much TV) 1. The non-Energy Star model uses 0. 5 k. W. How much will it cost you per year to run this model? $0. 15/k. Wh x 0. 5 k. W x 4 hr/day x 365 days/year $109. 50
2. If the Energy Star model uses 40% of the amount of electricity, how much money will you save over 5 years if you buy that model? $109. 5/yr x 5 years = $547. 50 x. 4 = $219 $547. 50 - $219 = $328. 50
Sustainable Design 1. Passive Solar Design: uses solar radiation to maintain indoor temperature Overhang • South-facing • Double-paned --Allows a building to retain heat or cold in the walls and floor
2. Recycled building materials
3. Green Roofs
