Staengl Engineering has provided MEP design services and energy modeling and analysis on several NetZero Energy residential projects for clients who wish to remain confidential. These projects included high-performance super-insulated building envelopes, the design and integration of solar PV arrays, advanced low-friction variable-speed geothermal systems, energy recovery systems, solar hot water systems with integrated heat recovery, and radiant heating.
These project designs include harvesting water for use on-site. One project collects and treats and re-uses black water for site irrigation. Another project incorporates a fuel cell to heat domestic hot water.
