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


20% gain in energy efficiency of existing

buildings

Removing ½ of all cars from the road=

3


Investments in energy efficiency are far cheaper than any new source of renewable power or expanding fossil fuel power plants


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

4


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


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

History of Green Building in San Rafael


§ Adopted green building requirements in 2007 for new construction onlyBUT 80% OF CONSTRUCTION WORK IN SAN RAFAEL IS REMODELLING§ Several buildings built or retrofitted to

green standards without City requirements



San Rafael Corporate Center: LEED Gold

Incremental construction cost: 1%

6



Northgate Mall: LEED Gold



Marin County Wellness Center: LEED Gold

Incremental construction cost: 6%

7



§ 2009 City Council adopted the San Rafael Climate Change Action Plan

§ Calls for adoption of green building regulations which apply to remodeling

How was the Green Building Ordinance created?


§ City elected to lead a collaborative process with all other Marin jurisdictions to develop a Model Green Building Ordinance

GREENBUILDING,ENERGYRETROFIT &SOLARTRANSFORMATION

§ Appointed a Task Force with representatives from each City Council or Planning Commission to provide policy direction

8



§ And a Technical Advisory Committee to recommend regulations GREEN

BUILDING,ENERGYRETROFIT &SOLARTRANSFORMATION

§ Marin Builders Association§ Marin Association of Realtors§ 2 Building Officials§ Architects§ Contractors§ Energy efficiency/green building auditors§ Energy consultants§ Marin Energy Authority§ PG&E§ Strategic Energy Innovations§ MMWD§ Marin Conservation League



§ Two agencies have adopted the BERST Model Ordinance (San Rafael & Marin County)§ Another is in hearings (San

Anselmo)

GREENBUILDING,ENERGYRETROFIT &SOLARTRANSFORMATION

What does the Green Building Ordinance require?


§ For standardization, use of two existing green building rating systems:

Residential Non-Residential



For standardization, use of two existing green building rating systems:

Residential Non-Residential

10



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



What about the new Cal Green state building code?§ Effective 1/1/11 unless alternate regulations

adopted locally § Does not apply to remodeling§ Mandatory measures are fairly minimal§ Enforcement would be through city inspectors§ Green Point Rated checklists being modified

to incorporate mandated Cal Green measures
