Health, air quality, daylight and views were key components of the design.
Minimum indoor air quality performance
The systems were designed to meet the required outdoor flow rates of ASHRAE Standard 62.1-2010. The spaces are ventilated by a base-building AHU. VAV boxes serve each zone in the project space. Each zone is sub-zoned with VAV diffusers with minimum ventilation set-points.
The project used the LEED budget calculation method to achieve 75% compliance with the CDPH SM V1.1-2010, Section 8 guideline for all products, including furniture.
Indoor air quality assessment
Both a flush-out and air testing (see report here) were performed to ensure exceptional indoor air quality. The air-testing report shows that concentrations of formaldehyde, particulates (PM10 or PM 2.5, as applicable), ozone (as applicable), total volatile organic compounds (TVOC), target chemicals from CDPH Standard Method v1.1, and carbon monoxide (CO) are within the LEED limits.
78% of the regularly occupied space has access to quality views.
