  11. 11. Creating a New Energy Reality …invest in energy and education… “To finally spark the creation of a clean energy economy, we will double the production of alternative energy in the next three years. We will modernize more than 75% of federal buildings and improve the energy efficiency of two million American homes, saving consumers and taxpayers billions on our energy bills. In the process, we will put Americans to work in new jobs that pay well and can’t be outsourced – jobs building solar panels and wind turbines; constructing fuel-efficient cars and buildings; and developing the new energy technologies that will lead to even more jobs, more savings, and a cleaner, safer planet in the bargain. …..That means updating the way we get our electricity by starting to build a new smart grid that will save us money, protect our power sources from blackout or attack, and deliver clean, alternative forms of energy to every corner of our nation.” President Obama – January 8th, 2009 Copyright: Garforth International llc
  12. 12. Total US Energy Use Coal Homes Buildings Gas 38.7% Commercial Domestic Oil Industry Uranium Industry 33.25% Renewable Transport Transportation 27.79% Import Oil Buildings largest energy consumer Copyright: Garforth International llc Source: US DoE EIA

State Law call for 20% reduction by 2014 Copyright: Garforth International llc
  17. 17. LCCC Energy Use 2007 Benchmark - Austrian and Ohio Colleges  LCCC Total Energy Index  375 kWhe/m2/year  79% higher than Austria average Lorain County CC Electricity Heat  Terra Community College  285 kWhe/m2/year  24% less than LCCC Average  Lakeland Community College  377 kWhe/m2/year  1% higher than LCCC  Owens Community College  438 kWhe/m2/year  17% higher than LCCC Energy Efficiency Potential Copyright: Garforth International llc
  18. 18. Evaluating energy needs Eight Buildings Modeled in Detail Copyright: Garforth International llc
  19. 19. Establish Baseline Example – University Center Seasonal Patterns End Uses Needs Energy Spot anomalies e.g. high plug loads Indexes Develop Energy End-Use Profiles Copyright: Garforth International llc
  20. 20. Typical Efficiency Measures Examples from multiple buildings  Upgrade roof insulation to at least R25  Eliminate thermal shorts in roof structure and window sills  Selectively replace windows  Install occupancy sensors  Implement daylighting control in atrium, corridors, classrooms, labs…  Realign and repair doors to reduce infiltration  Selectively add vestibules to high usage doors  Reduce plug load with staff/student awareness program  Manage heating, cooling and lighting according to scheduled needs Behavioral and Investment Based Copyright: Garforth International llc
  21. 21. Building Efficiency Many Opportunities Identified  Building operation  Heat and cool areas only when needed  Pre-condition areas according to weather  Night and low-occupancy set back of thermostats  Only light occupied areas  Utilize daylighting wherever feasible  Manage exterior lighting for real usage patterns  Reducing miscellaneous electrical loads  Building Structure  Roof insulation  Reduction of thermal bridges  Selective window replacements  Reduce unwanted air infiltration Improved control and metering is a Must Copyright: Garforth International llc
