The Delta T-90 team believes that high performance,
solar powered dwellings should be accessible to all and that good
design isn’t a function of cost. The Delta T-90 House is widely accessible as a
locally factory built solution for New England’s unique environmental and economic
challenges. Elegant detailing, high quality insulation,
streamlined mechanical systems, and an open floor plan enhance the way of life
of a household. The Delta T-90 house works.
“It works to maintain an interior temperature of 70 degrees when the exterior
temperature is negative 20, a 90-degree temperature difference.
It works…without compromising efficiency or livability.
We made THE solar-powered home that’s affordable for households earning 20%
less than the average Vermont median income. This is accessible.
This is here. This is now.
The open floor plan of the kitchen and living room is bright and spacious.
The Delta T-90 House maximizes the cost-per-square-foot value by
eliminating the mechanical room. By maximizing the building envelope,
systems are simplified to enhance the lifestyle of the occupants.
The skylight brightens the utility space. The extreme thickness of the wall section
we designed, 16 inches from inside to outside, differs from traditional stick-built
homes to confront the growing environmental and economic balance we need
in our homes. Dense packed cellulose and mineral wool insulation provides
the Delta T-90 House with a wall R-Value of 50.6.
The interior lighting and spatial qualities of the home create a comfortable
environment for a family to dwell in both public and private spaces.
High ceilings allow a compact and efficient design to become grand and
spacious. The thoughtful window placement fills the
living spaces with natural light and creates a connection to the outdoors.
The custom shading systems minimize direct heat gain in the summer months
while allowing natural lighting to the interior. The building integrated solar array provides
the house with enough energy to meet its annual needs assuming a conservation
based lifestyle. The thin-film amorphous photovoltaic array, lying flat on
the roof, eliminates the ‘solar hardware’ from the visual presence of the
house. The occupants will enjoy zero utility costs from heating, cooling, and household
electricity thanks to energy produced by the solar array.
This high-performance home models the future of affordable, energy efficient
living in Vermont.
