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’

Net Zero Energy Buildings

• Use = production

• Grid tied PV energy system

• DC/AC inverter

• ‘Net metering’

• 50% water

• Petroleum (construction)

• Petroleum (land use)

• LEED silver / Title 24
