Proof of Concept Passivista-COMPLETED
MainStream and owners Ken & Harlene recently completed one of Colorado's first Passive House residential buildings in December, 2012. The Passivista showcases many of the founding Passivhaus and green building principles while demonstrating feasibility and materials selection. Passivista is 3,600 sqft of true passive-house-ness with a cost at $97/sqft, and one of the tightest buildings at .23ACH50

Submit your plan sets in-time for spring build 2014
MainStream is looking for a few 'special' projects to build next spring. Sumbit your plan sets for review and gain first-hand how small changes can have big effects in the performance of your next home, multi-family or church. This includes remodels and special projects.

Welcome to MainStream

It all started with an intense infatuation with natural building methodologies and real estate investing. The thought that a person could build sustainably with nature and experience freedom off any grid, superior indoor environmental quality (IEQ), and extreme comfort. We then learned the science and methodology of Passivhaus, which challenged every building principle we thought we knew. Our sights are now set on helping others accomplish their visions where architecture meets science to produce extreme performance, comfort, and health.

In 2010 we were fortunate to have energy-conscience clients, and the Passivista was created! We tried all the products available on this proof of concept home, and are now Distributors for those hard-to-find solutions we've truly come to believe in, including our new Rocky Mountain Window. We are now working to complete our second residential passive house project in Colorado, the Traveler's Rest, soon to be on tour.

MainStream adds to the sustainable design, management, and build process by providing the energy target, which far exceeds most rating systems energy reduction goals.  Capturing energy loss is one of the easiest ‘low hanging fruits’ of green building as it is not technology-based or mechanically dependent. Loss-less design requires team energy, craftmanship, and a shared vision. We accomplish loss-less design with a tool box of constructible solutions and calculated identifiers to help assist owners, property managers, architects, builders, and investors to create cozy livable spaces for healthy humans.  By livable we mean quiet and peaceful, natural lighting in all rooms and constant fresh air. There are no drafts in our buildings or sensible convection currents. We're talking ventilation that REALLY works in the kitchen and bathrooms, and balanced comfort that is attracting thousands of new home owners, builders, and municipalities to instigate the Passive House high-performance building standard.
