Best Practices

Keep HVAC&R equipment cut sheets on file in the case that there is an urgent problem with the refrigerant in the equipment so that the refrigerant can be handled or replaced properly. 

Specify high-quality equipment with a dependably long lifespan. That way leakage is minimized at those times that carry the greatest risks; when the equipment is being installed or decommissioned. (For information about the service life of different types of HVAC equipment, see the 2007 ASHRAE Applications Handbook—HVAC Applications. See Resources.)

If HCFCs are being used, find out which type, understand the implications of using that refrigerant over the long term and if using more environmentally benign alternatives is possible.

Educate the occupants to properly use their controls and to turn them off during hours when the building is unoccupied or the space is not being used. 

Although not required for credit compliance, developing a plan to monitor the performance of lighting control systems is recommended. This may include occupant survey feedback (EAc5), ongoing monitoring (EAc3), and a schedule for regular testing of components.

Although not required for credit compliance, developing a plan to monitor the performance of lighting control systems is recommended. This may include occupant survey feedback (IEQc7.2), ongoing monitoring (EAc5), and a schedule for regular testing of components. 

Calibrate occupancy sensors and other lighting control systems (if included) after the installation of all office equipment and furnishings. Installing office equipment and furnishings after calibrating the lighting control systems could cause poor system performance.

Develop LEED documentation concurrently with or immediately following 100% Construction Documents.

Ideally, when specifying task or ambient lighting, lighting position should be adjustable and have multiple light levels. However, the credit can be satisfied with lights that simply turn on and off.

Examine project space allocation to evaluate whether there are any areas that present a challenge for meeting the requirements, or space programming that makes lighting controls inappropriate for the space.
