Fresh Air is filtered through the Zehnder fresh air ventilation system and distributed for interior health, all the while incorporating heat recovery from the exiting air. Experience a draft-free and radiantly-comfortable environment, in your own home! We are breaking thermal bridges, adding extreme air-tightness, and providing unmatched interior comfort.
Our Envelope Specialties allow for a reduced heater altogether, and a NET-ZERO result with less than half the normal PV system! MainStream has over 10 years practice in Passive House Green Building. Passive House is the easiest path to calculating and specifying off-grid, Zero Net Energy buildings of all shapes and sizes.

Integrated Design, Envelope Optimization and Specs, Passive House Certification and Feasibility Studies, & QA during Construction. Before a project ever obtains funding, there is an intense period of time where usually the Owner or Investors start visioning the purpose and solution the building will present.
Ventilation Consulting
Report
This means makeup air needs to be added to keep the bad stuff (Radon, Garage VOCs, dust, Attic insulation Particulates etc.) out of the building when using a clothes drier, a bathroom fan or range hood. Replacing the bathroom fans with our ERV systems can save up to 90% of the heat leaving your building!
Net-Zero & Passive Energy Models
Report
Passivhaus, aka Passive House in America, is a science based standard and energy model that balances passive solar, super insulation, air tightness, fresh air and heat/energy recovery, and the thermodynamic performance of a building to reduce typical building heat loads by 90%.
This target helps rating systems such as LEED, Living Building Challenge, NAHB Green, Energy Star, DOE Challenge Home and nearly every rating system hit net zero energy targets with real-time loss calculations.You'll know step by step what costs the most in the form of energy loss to a given building assembly.
