1. Minneapolis Climate http://www.eia.doe.gov/emeu/recs/climate_zone.html Warm humid summer Freezing winter + Snow Windy fall and spring High Humidity (southern part of MN)

3. High humidity Medium rainfall (as compared to other parts of the US)

4. Moderate summer + cool transition + very cold winter Dry bulb temp on x-axis and humidity on y-axis

5. Minneapolis climate vs Comfort Zone

6. Multiple strategies Evaluate which green strategies would work best..

7. SUMMER: Near comfort zone only certain days in summer Thermal mass effect + Natural ventilation are effective strategies (Thermal mass helpful for both winter and summer) Evaluate which green strategies would work best

8. WINTER: Passive solar works for certain parts of winter (+ thermal mass) Active heating system has to be used Using neighbor building, earth shelter can be other passive strategies Active heating – geothermal can be used to save energy Evaluate which green strategies would work best..

9. Passive Solar + Thermal mass Optimum position of building mass

10. Wind primarily from southeast and northwest- natural ventilation should be dsgned for these directions (Synonymous with passive solar orientation) http://climate.umn.edu/wind/kmsp.htm Zoning requirement: wind turbine for 4-storey house and up.
