  1. Energy Efficiency and Conservation By: Rochelle Tam and Izamar Capellan

  2. New York City Problems in Energy efficiency and conservation • Peak loads = strain on energy grid. • Electricity is drained while appliances are off. • Old infrastructure • Dependence on coal • Polluting power plants responsible for 80% of our global-warming emissions and 40% of all locally generated air pollution. • Old power plants use 30-60% more fuel than newer power plants. • Increase in population= increase in energy demands

  3. Research project: Background • New Yorkers spend collectively $13.4 billion on the energy that lights our buildings and powers our electronic devices. • It is responsible for roughly 80% of our global-warming emissions and more than 40% of all locally generated air pollution. • Increase production cell phones, laptops and other electronic devices have increased energy consumption.

  4. Research Project • Research Question: -HSES would be able to save money and electricity by unplugging all non-essential electronics that are plugged and draining unused electricity. • Hypothesis: - HSES will decrease its overall energy usage and save money if appliances where unplugged at night because they are not draining energy. . Many of the electronics have no off button and is on constant standby so by unplugging the appliances we would be able to eliminate the use of standby energy consumption

  5. Significance

  6. Methods : Study Site • located at 444West 56th street NY, NY 10019. • Estimated population of 1551 (1416 students, 120-140 staff and facility). • total of 214,075 sq ft area. • In the last 12 months (March 2010-March2011), HSES used 3,381,500 kHz. Using the average price of electricity (19 cents per KWH) that translates to $642,485 spent on electricity and 2,113,437.5 lbs CO2 emitted.

  7. Methods: Data Collection • Data was collected for each room had access to. We entered the classrooms and look for appliances that are plugged in and measure them using a volt meter. This data was imputed in an excel chart.

  8. Methods: Data Analysis • Input data into Excel • Calculate how much energy these appliances use with a voltage meter • Determine amount of money these appliances use up • Determine amount of CO2 emitted

  9. Results: Cost per Floor

  10. Results : Lbs of CO2 per floor

  11. Results: Cost per Appliance

  12. Results: Kilowatts per year

  13. Results: Lbs of CO2 per Appliance

  14. Discussion • We discovered that the limited amount of appliances that we tested can cost the school $1,710.95 a year. • A total of 14,407.96 lbs of CO2 is emitted per year by these appliances. • All of the appliances were tested on April 21st during spring break. • We lacked access to most offices in the school which includes the second floor guidance suite, some third floor offices and the library • The TVs in HSES are not energy stars and is outdated • By informing the community about how much energy can be saved, the result will be up to the community to switch habits to save energy.
