Net Zero Energy
• Make as much or more energy as the building uses over the course of one year
• Solar and Geothermal as primary energy generators
• Factors are: Building envelope, Glass, Lighting, Shading,
IT load, Hours of use
• Energy Use Intensity (EUI ) as metric

Very Difficult, but achievable!
New CPL EUI Target

Looking at EUIs
• Well Insulated, Non-drafty Building Envelope• Smart Use of Glass (good daylight, limit heat gain)• Energy Efficient Lighting (LED)• Daylight Dimming & Motion Sensing Controls• Every Efficient HVAC (geothermal, Water based Systems)• Buy-in from Occupants ( Un-plug at night, open and close
windows and shades)• Get Creative! (sewer system connected heat pumps? Using
water for thermal mass? Double walled sun room spaces?)
How would we get there?
