Energy and Atmosphere P3 – Fundamental Refrigerant Management (prerequisite)
Intent: Reduce ozone depletion. Implementation: New Building: Zero use of CFC-based refrigerants in HVAC systems Existing Building: Consider replacement or “phase-out” program for HVAC units and fire systems with CFCs. CFC production stopped in 1995 and was phased out 5 years after that. Existing mechanical systems connected to existing chilled water systems have to be […]
Indoor Environmental Air Quality 3.2 – Construction IAQ Management Plan – Before Occupancy
Intent: Reduce IAQ problems associated with Construction/Renovation process Help to sustain comfort and well-being of construction workers and building occupants Implementation: Develop and implement an Indoor Air Quality (IAQ) Management Plan for pre-occupancy phase Option 1: FLUSH-OUT after construction but before occupancy 14,000 cf of O/A (outside air) per sf of floor area maintain 60 […]
Sustainable Sites 3 – Brownfield Redevelopment
Tidbit: this credit happens to be one of the most expensive to implement. Thusly there are many government incentives / tax breaks to help.Intention: Rehabilitate damaged sites (environmentally contaminated sites) Reduce pressure on undeveloped land Implementation: Rebuild on a contaminated site as documented by ASTM E1903-07 or local codes. Brownfield definition by the EPA. CERCLA […]
Sustainable Sites P1 – Construction Activity Pollution Prevention (prerequisite)
This is a prerequisite credit. Prerequisite credits are mandatory credits that MUST be accomplished for a building to become LEED certified. There are 7 overall prerequisites in the New Construction version 2.2 LEED-AP reference guide which is the exam version this study guide covers. Construction Activity Pollution Prevention is the first. Intention: During construction, there […]
