Green and LEED Construction
Foothill College
Summer 2009
Overview
• What is green building?
• What is LEED?
• Why are buildings important?
• What is ‘the built environment’?
• How can green building and LEED help?
LEED & Green Building
• LEED building
• Green building
• New construction
• Remodeling
• Commissioning
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
Green Construction
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
LEED Platinum Buildings
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!
Residential / Commercial

The Built Environment
Campus Sustainability Planning Network
What is the Built Environment?
• Existing construction
• Older buildings
• 90 million residences
• Human construction
• ‘Anthropogenic Metabolism’
http://en.wikipedia.org/wiki/Built_environment
Net Zero Energy Buildings
• Use = production
• Grid tied PV energy system
• DC/AC inverter
• ‘Net metering’
Net Zero Residential

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

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