INDOOR ENVIRONMENTAL QUALITY
(LEED NCv2.2: 12 out of 15 possible points documented)
Indoor environmental quality has a direct correlation with occupant health, comfort, and productivity. NHS staff members working in the building and people attending classes in the large demonstration room benefit directly. Innovative approaches modeled by the Lab can be used at other small commercial facilities, and tours are conducted frequently to inspire others to build top-quality facilities.

• Carbon dioxide sensors are located in various spaces to automatically modulate outside fresh air as needed, based on interior carbon dioxide levels (a direct indicator of human occupancy), to minimize the energy required to condition ventilation air.
• The HVAC system allows for occupants to open windows, shut down mechanical equipment, and utilize natural ventilation for comfort and health. The HVAC system identifies when the outdoor environmental conditions are good and alerts occupants that they can open windows by illuminating a green light.
