Be aware of all requirements for interior lights so that fixtures do not direct their maximum candela through windows to the outdoors. Identify locations where fixtures might have a direct line of sight to a window or other opening. The lighting designer should either eliminate those fixtures from the design, provide shades to prevent the maximum candela from shining outdoors, or include controls to turn off all non-emergency lighting after hours.

All occupied spaces in naturally ventilated buildings require the installation of at least one CO2 sensor. The number of CO2 sensors depends on the project’s design and should be calculated by the mechanical engineer. Projects can use one CO2 sensor for multiple spaces only if the project is ventilated by an approved “engineered natural ventilation system” according to ASHRAE 62.1-2004 requirements and if it does not require occupant intervention.

CO2 sensors can 1) measure the indoor concentrations of CO2 and compare them against ASHRAE 62.1-2004 limits or, 2) measure the indoor concentrations of CO2 and compare them against outdoor CO2 concentrations. If you choose the second option, you will nee

Outdoor air can contain contaminants that lead to unhealthy working or living conditions. You may need to assess the quality of the local outdoor air before bringing it indoors. HHigh efficiency MERV filters (13 or higher) are one solution to treating poor-quality outdoor air before supplying it to the indoors. This can be part of a strategy for achieving EQc5: Indoor Chemical and Pollutant Source Control.
