1 Green and LEED Construction Foothill College Summer 2009


3 Overview What is green building? What is LEED? Why are buildings important? What is the built environment? How can green building and LEED help?

4 LEED & Green Building LEED building Green building New construction Remodeling Commissioning

5 What is Green Building? Lower impact construction Recycled construction material Siting / integration with environment Natural ventilation / heating / cooling Lower energy / water use / costs Green Point Rated USGBC – US Green Building Council

6 Green Construction

7 What is LEED? Leadership in Energy and Environmental Design – a point rated building system Design for low energy and water use Natural ventilation and lighting LEED (title 24) Silver, Gold, Platinum Next step to net zero energy buildings

8 LEED Platinum Buildings

9 Why are LEED/ Green Buildings Important? Buildings use 40% to 50% of all energy –60% of all domestic electricity => buildings Produce 40 to 50% of greenhouse gases Energy efficiency (design/retrofitting) can save 40 to 50% of total energy use Would free up 25% of electricity use 25% saved electricity could power an Electric Vehicle (EV) fleet – no petroleum!

10 Residential / Commercial

11 Elements of Green Building

12 Site planning and design Community Indoor air quality Energy Materials Waste Water Commissioning Elements of Green Building


14 Green Construction Jobs Demolition / site preparation Carpentry Structural PV installation Retrofitting Caulking / glazing

15 The Built Environment Campus Sustainability Planning Network

16 What is the Built Environment? Existing construction Older buildings 90 million residences Human construction Anthropogenic Metabolism

17 Net Zero Energy Buildings Use = production Grid tied PV energy system DC/AC inverter Net metering

18 Net Zero Residential Rooftop solar Battery storage Solar/thermal water heating Geothermal heating/cooling solutions Water collection

19 Energy Saving Lighting HVAC Heating Appliances Onsite PV Ducting

20 Natural Daylighting


22 Water Saving Fixtures Toilets Showers Irrigation Gray water Water collection


24 Siting and Integration

25 Healthier Living Natural daylight Odor free carpets Low VOC paint Natural materials Open architecture Natural settings

26 Retrofitting / Remodeling Retrofitting Remodeling Insulation Windows Doors

27 Reuse of Materials Demolition Dismantled buildings Containers Steel and glass Carpets

28 Natural Ventilation

29 Integrated Energy

30 Low Impact Construction Site integration Prefab / recycled materials Local / reused materials Safer chemicals

31 New Architecture Sunset Breeze -

32 How Much Energy Saved? 25 to 40% electricity 25 to 40% natural gas 50% water Petroleum (construction) Petroleum (land use) LEED silver / Title 24


34 Passive Energy Production Onsite solar (PV) Run of river hydro Geothermal / earth convection / circulation Integrated wind Stored energy (RP)

35 Future of Buildings
