Montgomery County Green Building Requirements

IGCC Logo

Montgomery County, Maryland recently passed new green building requirements, including adoption of the 2012 International Green Construction Code.  Montgomery County was one of the first jurisdictions in the country to enact a green building law in late 2007. Now, county officials have repealed the original law and replaced it with Executive Regulation 21-15 that will likely reduce requirements for many new buildings.

New Requirements

There are some pretty big changes brought about by the new law, which took effect on December 27, 2017 and includes a six month grace period for projects already under design. New projects permitted after June 27, 2018 will need to comply with the following:

  • Projects 5,000 gross square feet and larger must comply, lowered from 10,000 gsf.
  • Buildings must meet the 2012 International Green Construction Code (IgCC), replacing the requirement that buildings must meet LEED Certified criteria.
  • Residential projects under five stories must use ICC-700/NGBS at the Silver Energy Performance Level.
  • R-2 and R-4 portions of Mixed-Use buildings may comply with ICC-700/NGBS and the non-residential portion shall comply with the IgCC or the entire building may comply with IgCC or ASHRAE 189.1
  • R-1, non-residential and R-1/Mixed-Use projects may select IgCC, ASHRAE 189.1 or LEED Silver with eight points or more under the Whole Building Energy Simulation path.
  • All buildings using the IgCC compliance pathway must achieve a Zero Energy Performance Index (zEPI) score of 50 or lower.

Why the Whole Building Approach Matters

At Steven Winter Associates, Inc., we support the whole building approach to design and construction by doing our best to ensure that projects meet sustainability, energy efficiency, and accessibility requirements, among other design strategies and goals. From our perspective, accessibility compliance is a key factor in determining whether a project is truly sustainable and efficient.

The Whole Building Approach to Design (from the Whole Building Design Guide, “Design Objectives”)

As an example, I was recently contacted by a New York City-based housing developer. They received a letter from an attorney stating that three of their recently constructed projects in New York City were “tested” and found to be noncompliant with the accessible design and construction requirements of the Fair Housing Amendments Act and the New York City Building Code. SWA toured the buildings and confirmed that the allegations were in fact true. We identified issues such as excessive cross slopes along the concrete entrance walk, the presence of steps between dwelling units and their associated terraces, the lack of properly sized kitchens and bathrooms, the lack of compliant clear width provided by all user passage doors, etc. It quickly became apparent to us and to the developer that the cost of the remediation required to bring the projects into full compliance would be astronomical.

Don’t Be Scared of LEED v4

Written by Marina Dimitriadis, Sustainability Consultant

LEED v4 Changes and Updates

leedv4picleedarticleghostpicWe all knew the time was creeping up on us when LEED v2009, known as LEED v3,would no longer be an option. There are plenty of Halloween ghouls about, but LEED v4 shouldn’t give you a scare! We have a few key resources to help you understand the new rating systems and ensure a smooth transition.

LEED v3 Sunset and Registration Dates

All projects that wish to pursue LEED v3 must register  by October 31, 2016. Additionally, LEED v3 projects must certify by June 30, 2021. Projects that register now under LEED v3 can always transition to LEED v4 at no cost, but you can’t switch back to v3 after 10/31/16.

Unique Certification Options with National Green Building Standard™ (NGBS)

SWA_NGBS

If you’re unfamiliar with Home Innovation Research Labs’ National Green Building Standard™ (NGBS), the program is designed primarily to rate the performance of single-family homes or multifamily properties in six important categories: Site Design, Resource Efficiency, Water Efficiency, Energy Efficiency, Indoor Environmental Quality, and Building Operation & Maintenance. So how does NGBS differentiate itself from other green building rating systems? NGBS goes beyond the norm by offering certification paths for new land development and remodeling projects. Let’s take a closer look at these unique verification options. Read more
