4. The Sustainability Institute South Carolina South Carolina’s energy consumption is among the highest in the U.S. – South Carolina ranks 17th in per capita energy consumption. – 33 states are less wasteful than us! South Carolina has low energy prices! Electricity costs are: –Residential: 1.41 ¢ lower than the national average. –Commercial:1.6 ¢ lower than the national average. –Industrial: 1.2 ¢ lower than the national average. –Two new nuclear reactors could come online in South Carolina by 2016

9. T12’s, T8’s, & T5’s Oh My! – Efficacy: Efficiency in Lumens per watt ratio. Compact Florescent LED Lighting Bulbs Bulb TypeEfficacy T12 Tube60 T8 Tube80-100 T5 Tube70-104.2

10. The Sustainability Institute Ballasts Magnetic – Lower Cost – Warm the bulb to start Hybrid – Warm Bulb, then disconnect – Save approximately 9W per fixture Electronic – More Costly – Quieter, Brighter, No flicker – Save 15W per fixture – 15% more efficient

11. The Sustainability Institute Daylighting Ambient Office Lighting can consume Great amounts of energy. – XXkW per 9-hr Workday per fixture – XXkW per 24-hr period per fixture The Goal of daylighting is to reduce the need for artificial light. Blinds Light Shelves Tubular Skylights Hybrid Solar Lighting

12. The Sustainability Institute Sensors Daylight Sensors – Deactivate lighting automatically when enough daylight is available. Occupancy Sensors – Offices, Restrooms, Conference rooms, Break rooms – Infrared, Ultrasonic,Hybrid Timers – Programmed “ON” Period

13. The Sustainability Institute Ambient Vs. Task Lighting A quality lighting scheme should provide the right amount of light for the task. – Use daylighting strategies to reduce need for artificial light. – Direct light to walls and ceilings to reduce glair. – Use task lighting at workstations.

14. The Sustainability Institute Heating & Cooling – Learn to recognize comfort issues. – Infiltration/Leakage – Insulation – Ductwork – Balancing and re- commissioning

15. The Sustainability Institute The Trifecta of Building Science Envelope Leakage Duct Leakage Insulation

16. The Sustainability Institute Blower Door The blower door is a calibrated fan that measures air leakage. For every CFM leaving the house it must be replaced with an equal amount. Air Leakage Diagnostics

17. The Sustainability Institute Horror Stories Non-Profit Organization in North Charleston – Attic Access pathways – Spit Level Attic Non-Profit Organization in Charleston – Ductwork Problems – Indoor Air Quality Issues

18. The Sustainability Institute Retrocommissioning & Balancing Commissioning- The process of optimizing systems so they perform as designed. Balancing- The process of optimizing Air flow through ductwork to achieve comfort.
