The project I am working on is a mixed-use (mostly residential) neighborhood. There will be solar PV on every home as well as ground source heat pumps. The client and achitects are aiming for net-zero. They seem very confident that all exemplary performance points dealing with energy will be achieved.
However, they also plan on having a district heating and cooling system. The on-site renewables and ground source pumps will acount for much of the energy and heat needed. Where does this leave the points for GIBc12? The credit language states that district heating and cooling must account for 80% of the project's annual heating and cooling. If the majority of that is already accounted for through other measures, and it is not necessary that the district heating and cooling system supply 80%, does that mean that the credits are rendered unachievable?
Thanks in advance!
