Additionally, the Guild & Commons building is a Net Zero Energy building, using no power at all from the grid. Solar panels turn sunlight into electricity, a living roof insulates the building and supports pollinators, the lights are all efficient LEDs, and the building is fossil fuel-free.
地源热泵系统 The Guild & Commons uses a geoexchange system to provide both hot and cold water for the building. This pioneering technology absorbs and utilizes heat stored naturally in groundwater. There are twenty‐nine 490-foot‐deep wells on site. Water used to drive the system is recirculated through these wells. Through a very complex heat exchanger, the heat is extracted from the water to provide domestic hot water and hydronic heating through the floors, and also in unique ceiling tile. In a reversal process, cold water is produced to run through the hydronic system to cool the rooms when needed. The geoexchange system is much more efficient than a traditional water heater or HVAC system.
The Guild & Commons includes a sophisticated irrigation system that uses plants to filter reclaimed greywater from the kitchen sinks to water the surrounding gardens, as well as a rainwater catchment system.
