Green Building is Now the Law in Dallas
Dallas has now accepted the first building permit applications under its green building ordinance. Dallas is one of the first major cities in the nation to implement comprehensive mandatory green building standards for both all new residential and commercial construction.
By Resolution 08-1070 adopted unanimously on April 9, 2008 Phase 1 of the law was effective in 2009 and Phase 2 (originally to be effective October 1, 2011) was fully implemented October 1, 2013.
All new projects must either: meet the minimum requirements of the Dallas Green Construction Code or be LEED certifiable or be Green Built Texas certifiable or be certifiable under an equivalent green building standard. Projects need only be "certifiable" and not LEED certified nor Green Built Texas certified.
Expedited review is available for projects that are at a minimum Dallas Green Construction Code compliant, LEED Silver certifiable or ASHRAE 189.1-2011 certifiable.
Projects must reduce water usage by 20%. LEED projects may achieve 1 point under the Water Use Reduction (20% Reduction) Credit or projects may use 20% less water than the baseline under the Plumbing Code.
Single family residential may also meet the minimum requirements of ICC 700. Lots must be designed so that at least 70% of the built environment is permeable. Projects must utilize drip irrigation for all "bedding areas" of landscaping.
Significantly, as one of the optional compliance paths a project may comply with the Dallas Green Construction Code, which is an enactment of the International Green Construction Code with local amendments. Many have noted Dallas deleted Chapter 6 of the IgCC, the energy conservation provision, and elected instead to keep existing energy code requirements. Also deleted are the chapters for commissioning and causing the code to apply to alterations of existing buildings.
Dallas also accepts approved third party plan review and inspection for its green building program.
The successful implementation of green building standards in Dallas has been widely heralded across the environmental industrial complex, including on the USGBC website. Although there are some minor rumblings that LEED certifiable versus actually submitting a project for LEED certification violates the terms of usage of the USGBC rating system.
