Meeting the CALGreen LID Requirement in Dense Urban Areas
Melrose Triangle Building, West Hollywood, CA
Architect: Bijan and Associates, and Gensler
ENERlite Consulting provided CALGreen certification consultation for the Melrose Triangle Building. This project implements creative solutions to meet the CALGreen requirement for LID (Low Impact Development) stormwater pollution prevention in a dense urban area.
Melrose Triangle Building consists of a new 5-story above-grade core & shell and a mixed-use building of approximately 351,000 square feet including three levels of underground parking. It includes approximately 245,000 square feet of Class A office space, approximately 60,000 square feet of retail and restaurants, and an 80-unit multifamily residential building including affordable low-income units.
74% of the ground floor area is composed of impervious surfaces. The stormwater management system includes a cistern, pump, biofiltration planter box, and detention tank.
The LID Design consists of Green/Live Roofs and a singular LID Biofiltration Planter Box to treat the project’s stormwater. Excess stormwater runoff beyond the absorption capacity of the Green Roofs accumulates in an underground Cistern tank. Then, it is pumped to the biofiltration planter box for treatment and drained into the detention tank.
