Town Of Los Altos Hills July 17, 2008
Staff Report to the Planning Commission
RE: AMENDMENT TO TITLE 8, BUILDING REGULATIONS OF THE LOS ALTOS
HILLS MUNICIPAL CODE TO ADD A NEW CHAPTER 8-1.3, GREEN
BUILDING REGULATIONS
FROM: Debbie Pedro, AICP, Planning Director'
RECOMMENDATION: That the Planning Commission
Forward a recommendation that the City Council adopt the draft ordinance amending
Title 8, Building Regulations of the Los Altos Hills Municipal Code to add Chapter 8-1.3,
Green Building Regulations.
BACKGROUND
On May 22, 2008, the City Council directed staff to prepare a Green Building Ordinance
prescribing mandatory compliance with GreenPoint Rated and LEED guidelines for
construction of all new public facilities and new residences.
Green design and construction practices result in buildings that are generally less costly to
maintain, healthier for people and the environment, consume fewer natural resources, and
generate less waste than conventional building. Direct financial benefits of green
buildings come from lower energy and water bills. Other benefits of green buildings
include improved indoor air quality, protection of natural resources and the mitigation of
climate change. Additional information on green building can be found in the May 22,
2008 staff report to the City Council. (Attachment 3)
DISCUSSION
General Plan Consistency
The proposed ordinance is consistent with the Los Altos Hills General Plan goals,
policies and programs regarding protection of energy, water and other natural resources.
The following policies and programs in the Land Use Element address the Town's green
building goals.
Policy 2.8 Promote the use of green building methods and practices in the
planning, design, construction, renovation, operations, and
demolition of buildings. (Land Use Element, LU -9)
Program 2.8 Consider developing a green building ordinance for site development
and building applications. (Land Use Element, LU -10)

Green Building Requirements for Additions and Remodels
In May 2008, Council directed staff to study the possibility of including major remodels
and additions in the Green Building Ordinance. Build It Green (BIG), the nonprofit
organization that developed the GreenPoint Rated New Homes program, has recently
introduced a rating program for existing homes and remodels. In June 2008, staff
attended a two-day training on BIG's Existing Homes Rating program to evaluate
whether it is suitable to implement as a mandatory requirement for remodels and
additions in Los Altos Hills.
Since BIG's Existing Homes Rating program is still in its infancy and has not been
widely tested, it is recommended that the Town encourage voluntary participation for
remodels and additions at this time and evaluate adopting the Existing Homes Rating
guidelines again in the future.
Environmental Initiatives Committee Review
On March 17, 2008, Planning and Building staff presented a preliminary proposal of the
Green Building Ordinance to the Environmental Initiatives Committee. Several
developers building new homes in Los Altos Hills also attended the meeting and noted
that the proposal is reasonable. Some are already working towards GreenPoint
certification in their projects because green building is an added value and provides a
competitive advantage in their businesses.
Subsequent meetings with .members of the Environmental Initiatives Committee were
held on June 9 and June 30, 2008 and their comments and suggestions have been
incorporated into the draft ordinance. The following outlines key elements of the
proposed ordinance:
Applicability
The ordinance will apply to the construction of new residences and new Town -owned
public facilities over 1,000 sq. ft..
Standards for Compliance
This section sets forth the process, thresholds, and verification requirements for
applicable projects.

the California Environmental Quality Act (" CEQA') pursuant to Section 15308 of the
CEQA Guidelines because it is an action taken by a regulatory agency for the protection
of the environment.

TOWN OF LOS ALTOS FULS May 22, 2008
Staff Report to the City Council
SUBJECT: CONSIDERATION OF A PROPOSED AMENDMENT TO THE
MUNICIPAL CODE TO INCLUDE GREEN BUILDING
REGULATIONS
FROM: Debbie Pedro, Planning Director
APPROVED: Carl Cahill, City Manager
RECOMMENDATION: That the City Council:
Review and discuss the proposed green building regulations and direct staff to:
1. Prepare a green building ordinance prescribing mandatory compliance with
GreenPoint Rated and LEED guidelines with incentives; OR
2. Prepare a green building ordinance prescribing voluntary compliance with GreenPoint
Rated and LEED guidelines with incentives.
BACKGROUND
What is Green Building?
Green building is an integrated, whole -system approach to design and construction that
significantly reduce or eliminate the negative impacts of buildings on the environment
and occupants. Green building principles include:
• Energy Efficiency - Siting a building to take advantage of the sun and land
features for natural heating, cooling, and daylighting; Installing solar panels and
energy efficient appliances to reduce energy consumption.
• Water Efficiency - Landscaping with native, drought -resistant plants and water -
efficient practices.
• Conservation of Natural Resources - Reducing and recycling construction and
demolition waste; Incorporating durable, salvaged, recycled and sustainably
harvested materials in building construction.
• Health/Indoor Air Quality - Building quality, durable structures that is well
insulated and ventilated; Using paint and floor finishes that do not contain
formaldehyde or other harmful chemicals which can offgas and contribute to
indoor air pollution.
Staff Report to the City Council
May 22, 2008

Why Green Building?
Green design and construction practices result in buildings that are generally less costly to
maintain, healthier for people and the environment, consume fewer natural resources, and
generate less waste than conventional building.
Financial Savings
Green building makes a home more energy efficient, resulting in lower utility bills.
Proper orientation of a home can take advantage of the sun's radiant energy to provide
free natural heat in the winter while avoiding too much sun in the summer. In addition,
proper insulation, efficient windows, appliances, lighting, and water efficient landscaping
will reduce energy and water consumption and lower the operation and maintenance costs
of a building. According to a study released by California's Sustainable Building Task
Force, energy savings alone exceed the average increased cost associated with the initial
investment required to the design and construction of a green building. (The Costs and
Financial Benefits of Green Building, Attachment 3)
Environmental Benefits
Green building practices reduce greenhouse gas emissions and other pollutants associated
with building and energy required for heating and cooling. In addition, using recycled or
engineered wood products help preserve natural resources and reduce the environmental
impacts of producing new building materials through conservation.
Health and Comfort
Better insulation and proper ventilation of a home contributes to a comfortable
environment while using less energy. With tighter construction of the exterior envelope,
adequate ventilation is essential to allow excess moisture to escape and reduce the
potential for mold growth and buildup of allergens inside a building. Also, green
building products and materials can help reduce sources of indoor air pollution. For
example, the use of low VOC (Volatile Organic Compound) paint and formaldehyde free
kitchen cabinets will eliminate off -gassing and help improve indoor air quality.
Green Building Regulations in Los Alto Hills
In the past few yews, the Town has adopted various policies and ordinances that
encourages green building:
1. Deconstruction Permit Policy (Reso. 88-07, 11/8/07). Fee waiver and fast tracked
permits for deconstruction instead of demolition of buildings.
2. Development Area Policy (Policy Amendment, 10/11/07). Development area
credit for semi -permeable materials.
3. Free Solar Permits (Reso. 1-06,1/12/06)
4. Solar Ordinances (Ord. 446, 5/11/06, Ord. 500, 7/13/06). Development area
exemption for ground mounted solar installation and development area bonus for
roof mounted solar installation.
Staff Report to the City Council
May 22, 2008
Page 3 of 5
Because green building is most effective when designed and constructed as an integrated
system, it is proposed that the Town adopt a comprehensive set of green building
standards that addresses all aspects of green building. In November 2007, the Santa
Clara County Cities Association (SCCCA) recommended that local governments adopt
consistent green building policies throughout the county by using U.S. Green Building
Council's Leadership in Energy and Environmental Design (LEED) rating system and Build
It Green's GreenPoint Rated system as the official standards for their jurisdictions.
The US Green Building Council (USGBC) developed LEED program as a nationally
recognized rating system for new and existing buildings. Different levels of LEED
certification (Certified, Silver, Gold and Platinum) me awarded based on the total credits
earned. LEED is most commonly used for commercial, industrial, and multi -family
residential development projects.
Build It Green (BIG) is a professional non-profit membership organization whose goal is
to promote healthy and resource -efficient buildings. The GreenPoint program is designed
specifically for residential construction in California. It is consistent and compatible with
the California building and energy codes, and other third -party rating programs such as
Energy Star and LEED. The Northern California Home Builders Association has recently
endorsed the GreenPoint Rating program as the regional standard for green building.
According to BIG, 16 Bay Area cities and counties so far have adopted mandatory or
voluntary green building policies based on the GreenPoint program.

Mandatory vs. Voluntary
GreenPoint Rating and LEED certification provide uniform guidelines widely used by
other cities and counties in the Bay Area. Mandatory compliance guarantees project
certification and strengthens the Town's commitment to environmental protection. In
addition, the Northern California Homebuilders Association supports mandatory green
building guidelines based on GreenPoint Rating system because it is comprehensive, user
friendly, and attainable.
On the other hand, a voluntary program will give builders more flexibility during the
planning and construction stages of the project and a voluntary program could be used as
the first step to introducing a comprehensive set of green building regulations in Los
Altos Hills.
Proposed Ordinance
Staff recommends that through the adoption of a building code amendment, the Council
consider requiring new public facilities and new residences to achieve LEED certification
and GreenPoint Rating certification respectively.
A. New Public Facilities -Construction of all new Town -owned facilities and buildings
over 1,000 sq. ft. in size shall meet or exceed LEED® certification.
B. New Residences -Construction of all new residences shall achieve a minimum of fifty
(50) points based on the GreenPoint Rated checklist. (Maximum points possible: 266)
If adopted, the proposed ordinance will affect approximately 25 projects or approximately
5% of the total number of building permits issued each year. Between 2003-2007, the
Town.issued an average of 20-30 new residences per year.

Rewards and Incentives
To encourage compliance with green building regulations, the following incentives are
proposed:
ti• Expedited Permit Processing
For projects GreenPoint rated at 75 points or higher, the project would qualify for
expedite building plan review. Plan check comments on the first round of building
permit applications will be provided within five days of permit submittal.
•S Guaranteed building inspections
For projects GreenPoint rated at 100 points or higher, the project would qualify for
guaranteed building inspections within two working days of a request for inspection.
S• Recognition by the City Council
For projects GreenPoint rated at 150 points or higher, the homeowner would be awarded
a customized plaque recognizing the special achievement.
Environmental Initiatives Committee Review
On March 17, 2008, Planning and Building staff met with the Environmental Initiatives
Committee and presented the preliminary proposal of a Green Building Ordinance using
the GreenPoint Rated program.
Several developers building new homes in Los Altos Hills were also invited to the
meeting. The builders said the proposal is reasonable and some are already working
towards GreenPoint certification in their projects because green building is an added
value and provides a competitive advantage. The Committee also indicated their support
of this effort and staff is continuing to work with the Committee on the proposed
ordinance and incentives. (Attachment 4)
Conclusion
At this time, staff is seeking feedback and direction from the Council on the proposed
Green Building Ordinance, The Council could decide to pursue mandatory requirements
with incentives. Alternatively, the Council can choose to adopt the GreenPoint Rated and
LEED guidelines as a voluntary program and include incentives to encourage compliance.
