GB7: Alternative Thermal Production

(5-11 points)

Purpose

Produce hot water in an efficient manner.

Criteria

Produce a percentage of projected annual output of the central heating and cooling plant through solar or combined heat and power sources.

The strategy must provide a community-wide system. Any systems localized to individual homes/units will be awarded through the appropriate EarthCraft building program (ECH or ECMF).

50% of the combined heat and power output can be considered for this calculation.

100% of a solar thermal system can be considered for this calculation.

Percentage of Projected Annual Central Heat/Cooling Plant Output provided by Alternative Sources	Points
5%	5
10%	7
15%	9
20%	11

Projects may earn a maximum of 20 points from the District Heating/Cooling, Renewable Electric Generation and Alternative Thermal Production credits.

Verification 

• Narrative describing the type of system to be installed and the units/buildings expected to be served. 
• Calculation of the expected total annual output of the central heating and cooling plan in BTUs. 
• Calculation of the total annual output percentage that will be provided by solar or combined heat and power.
• Utility installation plans and construction documents detailing the district energy plan and sources of alternative energy. 
• Calculation of actual total annual output of the plant in BTUs and percentage provided by solar or combined heat and power.
