Learning Objectives:

The following points are identified as Learning Objectives for CES Credit, and are th i th t ill b d i t d ’ t ti among the issues that will be covered in today’s presentation.



The members will be introduced to the new CAL-Green sustainable standards that will take effect throughout California on January 1, 2011



The members will learn the format of the new code



The members will review the way they can identify which part of the code will apply to residential projects versus non-residential



The members will learn about the enforcement of the “Minimum Mandatory Standards” throughout California as well as the potential local additional “Tier 1” and “Tier 2” standards in various communities

Why do we need a “Green Code”

R i lik LEED d G P i h

 Rating systems like LEED and Green-Point have

been around for years, so why does California need CALGreen? CALGreen?



Voluntary rating systems do not apply to all new projects, and all jurisdictions do not require such programs. C lif i i th d t t ti ll d



California recognizes the need to systematically reduce non-sustainable building construction practices, and use

• bjective.



Greenhouse gas emissions, energy use, and potable water consumption need to be reduced.

Code vs. Rating System

 A “Code” establishes a minimum standard that has

been deemed desirable for an entire community. Every individual subject to the code must meet the Every individual subject to the code must meet the established standards in order to pass.

 Codes can be “prescriptive based” “performance  Codes can be prescriptive-based , performance-

based”, or both.

 Prescriptive requirements ensure that desirable goals  Prescriptive requirements ensure that desirable goals

are always met, while performance standards allow flexibility in meeting over-all objectives. y g j

Code vs. Rating System

 A “Rating System” is intended to allow a

relative comparison between similar products.

 Rating systems generally award “points” or

“credits” in a manner that will allow a relative ranking of achievement.

 Rating systems can be successful tools in  Rating systems can be successful tools in

fostering competitions among motivated participants. participants.

Purpose



The primar p rpose of CALGreen is to impro e p blic



The primary purpose of CALGreen is to improve public health, safety and general welfare by enhancing the design and construction of buildings through the use of building concepts having a reduced negative impact or positive concepts having a reduced negative impact, or positive environmental impact and encouraging sustainable construction practices in the following categories:



Planning and design. g g



Energy efficiency.



Water efficiency and conservation.



Material conservation and resource efficiency.



Environmental quality.



It is not the intent that CALGreen substitute or be identified as meeting the certification requirements of any green b ildi building program.

Systematic & Comprehensive y p Adoption of CALGreen

 O i i

ll d t d i A t 2009

 Originally adopted in August 2009



No additional mandatory standards beyond existing code requirements.



All other provisions were 100% voluntary.



Considered the first step towards a comprehensive code.

 “CALGreen” adopted on January 12, 2010 

Applicability to all facilities January 1, 2011



Local Adoption



Most local j risdictions that do not ha e an e isting ell



Most local jurisdictions that do not have an existing, well- established green building program appear to be “leaning” toward a basic adoption of the CALGreen minimum mandatory standards mandatory standards.



As CALGreen raises the awareness of sustainable construction benefits throughout the state, designers, builders, and code enforcement officials will gradually become more and code enforcement officials will gradually become more competent and comfortable applying the new standards.



Local jurisdictions that have effective existing programs in place will be able to maintain their higher standards, while p g , the rest of California gradually “catches up”.



As California continues to enhance CALGreen through its systematic & comprehensive 3-year code adoption process, y p y p p , all of California will move in a convergent direction toward an increasingly more sustainable code.

Local Adoption

 California Health and Safety Code 17958 & 18938



Local adoption within 180-days of publication. M d th d if bl j tifi d th b i f



May amend the code if reasonably justified on the basis of a local geologic, topographic, or climatic condition.



Local amendment may not be less protective than the y p minimum state standard.



Justifications for local amendment must be filed with the C lif i B ildi S d d C i i i California Building Standards Commission prior to enforcement.

Code Adoption Timeline

Effective Date

 On January 1, 2011, CALGreen will take effect.  If local amendments are adopted, such amendments

ill k ff h i id d l l will take effect at the same time, provided local adoption is completed sufficiently prior to the effective date effective date.

 If local adoption is delayed, any specific local

amendments may not be legally enforced until local amendments may not be legally enforced until local adoption is completed and the amendments & justifications are filed with the CBSC. j

Who Will Enforce CALGreen?

 CALGreen will be enforced for private

development by local Building Departments.

 CALGreen will be enforced for state-facilities

by the appropriate state agencies.

 Hospitals – OSHPD  Public Schools – DSA  Mixed Authority – combination of state agency

and municipal agency involvement p g y



California has a continuous 3-year code development process which results in ever-improving minimum standards p g



CALGreen construction standards will gradually be absorbed/incorporated into other parts of Title-24, thereby resulting in “greener” building codes
