Case Study: Christchurch Civic Centre Tri-generation Project Summary, NZ

Christchurch Tri-generation Project Summary, Entec, 2010 - Tri-generation refers to the conversion of one energy input (in this case, landfill gas with a methane content of between 50-60%) into three energy outputs; electricity, heat and cooling. The heat recovered from the gas engine’s jacket water and exhaust gas streams is to be used for both heating of the building and to power an absorption chiller for air conditioning. Fuel gas for the project is being piped from the 90 hectare Burwood Land-fill which operated between 1984 and 2005 on the north-eastern outskirts of the city.
