Why LEED Mandates Do Not Add Up

On Wednesday, we discussed the LEED 25 percent rule: the LEED rating system was only intended to apply to the top 25 percent of buildings.

It is important to remember this premise when considering what is happening in the green building industry today. Many cities are mandating LEED certification for public and private buildings. For example, in Washington D.C., all new construction of private buildings greater than 50,000 square feet will have to be LEED certified after January 1, 2012.

As cities, states and federal agencies are mandating LEED certification, you simultaneously have the USGBC "raising the bar" for green buildings by bi-annually updating the LEED rating system to include even more stringent requirements for certification. The USGBC's goal is not for every building in the country to be LEED certified. Instead, the USGBC wants "to bring in even greener and greener buildings."

You see the problem there. I know you do. But I will say it anyways.

Mandates require 100 percent compliance.

The USGBC is designing a system that only the leading 25 percent of buildings can comply with, at least in terms of certification.

Those two numbers do not add up.

Congress Drills Down Green Building Regulation

You may remember that in previous posts, GBLU warned that September was going to be a big month for green building regulations in Washington D.C. It was anticipated that the D.C. City Council would vote on new green building codes on September 16 but the codes were tabled to allow for more feedback from affected parties. But there was still significant green building regulations voted on yesterday in D.C.

Late Monday night, H.R. 6899, the Comprehensive American Energy Security and Consumer Protection Act, was passed by the House of Representatives by a vote of 236-189. The big story will be that an energy bill was passed that permits more oil drilling off U.S. Coasts. But as expected, the legislation also included green building mandates. 

 

Among these mandates is Title IV – Greater Energy Efficiency in Building Codes. This section requires the Secretary to update the national model building energy codes and standards at least every three years to achieve specific overall energy savings, compared to the 2006 IECC for residential building and ASHRAE Standard 90.1-2004From prior discussions, you may remember ASHRAE 90.1-2004 is the energy standard used by the USGBC’s LEED rating system

 

But GBI’s Green Globes rating system also found its way into the legislation. Under Title VI – Green Resources for Energy Efficient Neighborhoods, the legislation described requirements for both residential and non-residential projects seeking HUD assistance. Among these requirements, to qualify for HUD assistance projects can comply with one of numerous green building standards:

 

1)      The national Green Communities criteria checklist

2)      The gold certification level for the LEED for New Construction rating system, the LEED for Homes rating system, or the LEED for Core and Shell rating system

3)      GBI’s Green Globes assessment and rating system; or

4)      The National Green Building Standard

 

It seems peculiar that this legislation would require LEED gold certification but not include a similar requirement for Green Globes. Like the LEED rating system, Green Globes awards “globes” for each level of certification. The equivalent of LEED gold certification would be achieving three globes through Green Globes. 

 

Word on Capitol Hill is that the Senate is likely to adopt a different version of energy legislation so it is unclear whether green building mandates will be included in the Senate’s version.   

Green Building an Election Issue?

One factor that has significantly increased demand for green building is government regulation that requires green building strategies. So far, GBLU has focused green building initiatives at the city level. While there has been some federal green building legislation, GBLU anticipated major federal green building legislation would emerge from Congress in 2009.  It now looks like federal green building mandates could be voted on before the 2008 presidential election ever occurs. 

As Congress returns to Capitol Hill today from the two parties’ conventions, one of the primary issues on the table is energy policy and offshore drilling.  A recent Greenwire article detailed how Democrats intend to offer a piece of legislation that includes energy-efficiency standards for buildings in order to counter the congressional Republicans demand for offshore drilling:

Top House Democrats say that shortly after Congress reconvenes, they will put on the floor a piece of legislation that will include an expansion of offshore drilling but also a renewable electricity mandate, energy-efficiency standards for buildings and oil industry tax provisions.

Under the USGBC’s LEED rating system, projects must satisfy a minimum energy performance by complying with provisions in ASHRAE 90.1-2004. The Democrats’ legislation could require compliance with ASHRAE 90.1-2004, or a similar standard, like the EPA’s Target Finder.  

 

GBLU was on Capitol Hill on Friday to discuss what additional Federal green building legislation might look like. The consensus was that Federal green building legislation would most likely come in the form of mandates for specific green building components. For example, Federal legislation could mandate the use of Energy Star compliant appliances. The list of possible green building mandates is long: insulation, certified wood and pervious paving are just a few. 

 

If you think of other potential green building mandates, please submit a comment below. GBLU would like to put together a list and discuss what each mandate could look like.
