Gunbarrel apartment complex achieves LEED silver certification

BOULDER — Apex 5510, a 231-unit apartment complex in the Gunbarrel community of Boulder, has received a LEED silver certification from the U.S. Green Building Council.

“Sustainability is a focal point for our company, and we know that it is a priority for many of the people who live and work in Boulder County,” said Brad Blash, co-founder and managing partner of Crossbeam Concierge, which partnered with Trammell Crow Residential on the development.

The LEED rating system takes into account sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.

Apex 5510 met a list of requirements including:

• Low flow fixtures, reducing occupant water use;

• 30 percent energy reduction;

• Sealed combustion equipment and mechanical ventilation to improve indoor air quality;

• Eco-sensitive landscaping including drought-tolerant plants, zoned irrigation for water conservation and a limited amount of turf;

• HERS rating of at least 70 for each dwelling unit. HERS is an acronym for home energy rating system. The index is industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting, testing and calculating a home’s energy performance.

The complex is also smoke-free and complies with Boulder’s Green Points Program.
