California Greening: State's New Green Building Codes Have Some Crying Foul

'An Example of the Law of Unintended Consequences'

By Amy Westervelt

Jan 20, 2010

California last week became the first state to integrate green building practices, largely based on the U.S. Green Building Council’s Leadership in Efficiency and Environmental Design (LEED) standards, into its statewide building codes.

It was a big, Governator-style move, but while the USGBC officially supports , and most in the green building world see it as a net-positive step, not everyone is thrilled about it. In fact many architects, engineers and city planners that fully support the integration of green building practices in the building code are concerned about the challenges involved in implementing and enforcing that code — and those are the building professionals who are advocates of green building in the first place.

“I think we’re living through an example of the law of unintended consequences here,” says Bill Worthen, a member of the American Institute of Architects.

Worthen helped draft San Francisco’s municipal green building standards and was involved in the three public hearings held as the state standards were drafted.

“The intent of LEED was to transform the market, and it was targeting the top 25% of buildings in the construction market," he said. "What has happened is the USGBC has grown into an enormous organization, and it has done a great job of framing the discussion on sustainability in construction — so much so that it has made state governments, ASHRAE, and everyone else all want to draft their own green building standards, and they all borrow from LEED.”

That would seem to be a good thing, or at least not a bad one, but in fact it is causing problems.

Competing Codes, Lack of Flexibility

Whereas in and in most existing municipal green building codes there is flexibility built in so that architects and developers can decide what works best on their project and find the most cost-effective way to achieve the level of sustainability they want, the state codes make these things mandatory and, according to Worthen, “no one understands what that means.”

To wit, what if the local planning commission requires green front lawns, but the building codes require reduction in water use — which rules win out? Similarly, if the building codes mandate, say, the use of storm-water catchment, but it doesn’t make sense at a particular location, it might not actually be the most eco-friendly construction choice. And, Worthen points out, if a designer is doing something really creative, such as a structured wetland, and it’s something that isn’t covered by the codes, what happens then?

Another concern about the CalGreen system is that it’s not just one set of codes.

There’s the initial, mandatory baseline code, but then the state is introducing two tiers that municipalities can adopt if they want to go above and beyond. The cities that adopt the higher tier will be more expensive to build in than the cities that adopt just the baseline code. In cities like , where green building codes are already in place, the municipal codes will trump the state codes, provided they are equally or more rigorous.

There are concerns within the building industry about the potential confusion caused by having first the variations on the state code (mandatory, Tier One and Tier Two), and then the different local building codes. And how does it all interact with LEED?

“LEED and building codes are always complementary, and this just helps integrate green building practices further into the code,” says Jason Hartke, vice president of national policy for USGBC. He notes that the organization has a history of supporting improvements to building code minimums, and that its multiple California chapters were involved in the development of the Calgreen standards.

“We were worried at first that state codes would prevent localities from going beyond what the state has put in place, but we helped drive some changes early on that eliminated that problem."

Impact on Green Construction

CAL Green

It is good to see California taking such an initiative to strengthen environmental standards in the state. Hopefully CAL Green and LEED will be able to work together, since a greener America is the ultimate goal. Thanks for the article.

Where the rubber meets the road - unhappy consumers...

Speaking from an Electricians standpoint - there is nothing that makes a building owner more unhappy than me having to tell them that the state has made design choices in lighting and controls in their home. All of the many other green ticket items in the home they are building or remodeling hardly get noticed or acknowledged unless there is significant cost involved. No one seems to care about the recycled blue jeans used as insulation, or the reclaimed framing - but lighting gets noticed...

California's Title-24 Part 6 is clearly written by manufactures boosting sales of their highest priced products by legal mandate... While there are a few 'out's' available from high efficacy lighting - which varies by price and subsequently quality - many of those 'out's' are not available to all economic classes. This leaves the middle class in California starved for lighting that does not cause seizures - or just painful to look at... While the excessively rich get the highest quality cutting edge lighting - while it still may not be completely pleasant to read by, one could still brag about their energy savings... But the middle class is waiting for the inspector to leave to start the 're-remodel' to get rid of their cheapest available - but still expensive CFL's and vacancy sensors.

Dare I say it - I'm not looking forward to the future of educating Architects, Designers and home-owners about what I have to force down their throats...

Costs vs. savings

It's hard to educate people that they will be saving more money in the long run with these new technologies. Not just for themselves, but saving the state money as well -- their tax dollars are diverted to deal with public health effects and the ever-increasing costs of fossil fuel power generation instead of other critical areas like education and public safety.

People always complain about building code changes, even when it's for earthquake-resistance and building safety: the changes were intangible and utterly intrusive until that day when suddenly people were directly affected, and saw the consequences.

Education is key -- once people understand the actual benefits (instead of the spin), they are much more amenable to these changes.

Broad Support for CALGREEN

Last week, the California Building Standards Commission effectively “mainstreamed” green building provisions into the body of our state building codes, making California the first state in the nation to do so.

With regards to the issue of "third-party verification", the Building Standards Commission and the Department of Housing & Community Development simply went with standard operating procedure used over the past 30+ years by putting the local building department in charge of plan check and inspection of green building provisions; just as they are for structural, seismic, fire safety, disabled accessibility and energy efficiency provisions in the code. If a local jurisdiction is inclined to “farm-out” some (or all) of its administrative authority to one or more private sector entities, they have that authority. For decades, many local jurisdictions have been going to private sector entities for help in plan checking and inspecting state and local code provisions. All the BSC did last week was to refrain from encroaching on this local authority.

Broad Support for CALGREEN

This story does not mention that there is extremely broad support for these codes. More than 20 professional organizations from AIA to all major real estate groups to the organization representing local building officials, are officially on record supporting what California adopted.

Confusion is created for design and construction professionals when a patchwork of local standards based on private programs are overlaid on the base codes and CALGREEN will increase sustainability while minimizing confusion.

I am not sure why the minimum building code - CALGREEN - and LEED are seen as competing. They should work in conjunction with one another to further increase the minimum level of sustainability in our state for all new buildings, while facilitating the envelope to continue to be pushed with private standards and the top 25%.

It will be tough, but most people believe our industry it up to the task!
