What is Green Building?What is Green Building?
A coordinated and performance-basedapproach to building design, construction and operation to:§ Reduce energy consumption§ Reduce water use§ Improve interior air quality§ Use more sustainable resources§ Reduce construction waste
2
Why Green Building?Why Green Building?
§ Energy use in buildings (electricity, heating & cooking) is responsible for 34% of local greenhouse gas emissions§ Indoor air quality is typically 3-10x worse
than outdoor air§ Construction debris accounts for 12-25%
of waste going to landfills
Why Green Building?Why Green Building?
20% gain in energy efficiency of existing
buildings
Removing ½ of all cars from the road=

Why Green Building?Why Green Building?
Investments in energy efficiency are far cheaper than any new source of renewable power or expanding fossil fuel power plants
Why Green Building?Why Green Building?
Green building, if done wisely, can increase initial construction costs 1-6%, but…§ The payback period from energy savings
is typically 3-7 years (and generates positive cash flow for the remaining life of the building) - $200 in annual energy savings ≈$40,000 over the life of a building§ Green commercial buildings have a
higher lease rate and sales price

Why Green Building?Why Green Building?
Green building, if done wisely, can increase initial construction costs 1-6%, but…
§ Rental rates for LEED buildings are 6% higher
§ Selling prices for LEED buildings are 16% higher
Why Green Building?Why Green Building?
Green building, if done wisely, can increase initial construction costs 1-6%, but…§ Tenants in commercial buildings are
demanding green building§ Studies have demonstrated 16% higher
worker productivity in green buildings

Benefits of using Green Point Rated and LEED rating systems:§ Consistency with other jurisdictions § Regulations developed & frequently updated
with extensive building industry involvement§ Provide many options/choices for applicants§ Excellent educational materials§ Good quality control systems (building audits)§ Large number of trained designers and raters
