Intent

To reduce energy consumption associated with the heating and cooling system.

Requirements

Design and install HVAC equipment that is more efficient than the equipment required by the ENERGY STAR for Homes, version 3, prescriptive pathway. Points are awarded according to Table 1.

Any piping designed as part of a heat pump system to carry water that is well above (or below) the thermostatic temperature settings in the home must have R-4 or better insulation. Refrigerant piping must be insulated to R-6 or better on the air-conditioning mode suction line or the heat-pump mode discharge line.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
