Green Building Law Blog : Green Building Lawyer & Attorney : Shari Shapiro: Calliope Communications, LLC

At the National Association of Home Builders' Green Conference in Dallas this weekend, conversation turned to retrofitting buildings.  There was universal acknowledgement among the homebuilders I spoke to that building new homes was going to be dwarfed by retrofitting and renovating existing dwellings for the next decade.   

There has been a lot of discussion about upgrading building codes to incorporate green standards.  ICC is working on a commercial green code, and ASHRAE recently released a new draft of standard 189, also for commercial green buildings.  NAHB developed an ANSI/ICC standard for residential green building, NAHB Green.     

The problem? Many building codes do not apply to residential renovations. In Pennsylvania, the Uniform Construction Code does not apply to: 

(8) Alterations to residential buildings which do not make structural changes or changes to means of egress, except as required by ordinances in effect under sections 303(b)(1) or 503 of the act (35 P. S. § § 7210.303(b)(1) and 7210.503). Under this subsection, a structural change does not include a minor framing change needed to replace existing windows or doors.
 
(9) Repairs to residential buildings, except as required by ordinances in effect under sections 303(b)(1) and 503 of the act.

So, even if the building codes are upgraded to be "green," many home renovations will not need to comply, thus leaving behind a big chunk of existing building stock.

One possible solution is to apply the standard new construction building code to all projects.  New York has recently announced its intention to do this with respect to its Energy Code.   Opponents argue that forcing every small house renovation to comply with the components of the comprehensive building code would be unnecessarily costly and burdernsome.

The other is to develop an existing building code, alongside the building code for new construction, that applies specifically to retrofits.  The ICC already has an existing building code, and it could be used as a base for creating appropriate green requirements for even small renovations.  The key is keeping the requirements simple and focused on key green priorities which can be addressed in even the smallest kitchen renovation--construction waste management, energy efficiency, water conservation, indoor air quality, and materials reuse.

The International Code Council, the non-profit organization which develops and maintains the International Building Code, announced on Earth Day that they were creating a new "green" commercial building code which would be in line with the ICC's other building code products. 

ICC codes are "consensus" based codes, so the process for developing the code involves:

• Convening a select drafting committee
• Inviting public comment on the initial draft
• Placing the final draft into the ICC code development process

This code may address the common criticism of LEED and other green building standards that they are not designed to be incorporated into building codes, and that they are not specific enough to be used as legal platforms. 

ICC is not the first organization to attempt to create a building-code friendly standard for green.  ASHRAE convened a committee to develop Standard 189.1 several years ago 

Proposed Standard 189, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, will provide minimum requirements for the design of sustainable buildings to balance environmental responsibility, resource efficiency, occupant comfort and well-being, and community sensitivity. Using USGBC’s LEED Green Building Rating System, which addresses the top 25% of building practice, as a key resource, Standard 189P will provide a baseline that will drive green building into mainstream building practices.

Standard 189P will be an ANSI-accredited standard that can be incorporated into building code. It is intended that the standard will eventually become a prerequisite under LEED.
 

After releasing a draft standard in 2007, the ASHRAE dissolved the original committee in late 2008, and reconstituted it at the beginning of 2009.  There was a great deal of scuttle that the committee was dissolved because major builders, manufacturers and developers did not have enough of a say in the development of the standard. 

It will be interesting to see if ICC will be more successful that ASHRAE in developing a commercial green building code, and whether that code will, in fact, be green.  ICC developed a residential green standard with the National Association of Home Builders, and the criticism of the NAHB Green standard is that the requirements are not as stringent as LEED for Homes.  We shall see if the ICC green commercial standard will incorporate the same green requirements as LEED-NC. 

Finally, even creating an ICC green code will not solve the issue expressed by code officials that there is a lack of expertise and training in green construction.  In fact, if the ICC code is developed and adopted in municipalities and states across the country, a much greater investment will be required in training, education and expertise to ensure that the codes are implemented and enforced properly.
