TECHNICAL BULLETINS

At Gasser Bush Associates, we can assist lighting specifiers with obtaining technical information for products, energy codes and applications.  An increased need for lighting technical information exists due to Michigan's adpotion of the ASHRAE 90.1-1999 building energy code and increased interest in LEED products.

LEED

LEED (Leadership in Energy and Environmental Design) is a system for evaluating buildings that are sustainably designed and constructed, better known as “green” buildings. The LEED rating system was developed and is administered by the USGBC (U.S. Green Building Council).

LEED quantifies the sustainable design process by providing quantifiable and measurable guidelines in five different categories.  Each category has prerequisites and opportunities to accumulate points.  A minimum number of points must be achieved for a building to be LEED Certified.  Additional points may be earned to achieve LEED Silver, Gold and Platinum ratings.  Following are categories where lighting can assist with achieving LEED credits.

Potential Point Contributions
Refer to latest LEED Reference Guide for specific requirements, submittals and strategies.
 

Sustainable Sites
Credit 8: Light Pollution Reduction, 1 Point
Intent: Eliminate light trespass from the building and site, improve night sky access and reduce development impact on nocturnal environments

Energy & Atmosphere
Prerequisite 1: Fundamental Building Systems Commissioning
Intent: Verify and ensure that fundamental building elements and systems are designed, installed and calibrated to operate as intended.

Prerequisite 2: Minimum Energy Performance
Intent: Establish the minimum level of energy efficiency for the base buidlign and systems.

Credit 1: Optimize Energy Performance, 1-10 Points
Intent: Achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associate with excessive energy use.

Credit 1: Additional Commissioning
Intent: Verify and ensure that entire is designed, constructed and calibrated to operate as intended.

Indoor Environmental Quality
Credit 6.1: Controllability of Systems for Perimeter Spaces, 1 Point
Credit 6.2: Controllability of Systems for non-perimeter spaces, 1 Point
Intent: Provide a high level of thermal, ventilation and lighting system control by individual occupants or specific groups in multi-occupant spaces to promote the productivity, comfort and well-being of building occupants

Daylighting control is not a specific LEED Credit, however, we have the products and specialists to assist in developing controls/switching/dimming for daylight harvesting and control to further maximize energy savings.
