4 Conventional Design Practice Practices of Inefficiency Insufficient Insulation HVAC Systems oversized Ductwork too narrow Control System incorrectly sequenced Wrong Windows installed Exterior shading not considered Fans, pumps, compressors are fixed speed IAQ poorly managed Appliances vent hot air into building Incandescent and halogen bulbs still installed No occupancy/daylight sensors No real time monitoring

5 Best Practices for Net Zero Design Check List for Energy Efficiency 1. PV for net metering credit 2. Thermostat in every room 3. Variable speed fans, pumps and compressors 4. Modulating boilers 5. Tankless water heating 6. Geothermal heating & cooling 7. Low E Windows 8. Dimmable LED lighting with sensors 9. R40 Insulation minimum 10. Monitoring 5
