Annex Building – This new building will have the best

opportunity to achieve energy and water efficiencies. In

fact, we recommend that we strive for a net zero building,

meaning that the building will produce as much energy

and collect as much water as it will use.

The envelope will be critical in this goal. Whatever the

building design becomes, the skin will need to be highly

energy efficient.

The same with HVAC. We recommend exploring using a

geothermal well system to provide heating and cooling

energy for this new building. This would be coupled with a

water source heat pump system or a VRF system to heat

and cool the building.

All plumbing fixtures and faucets would be very low flow

and water saving. The debate continues on waterless

urinals, but we believe a one-pint flush urinal is a good

solution. The roof should be designed to be able to collect

rainwater and store it for re-use in the building. It would

need special filtering and treatment to be able to use for

drinking water, so that may be a compromise in this goal.
