A Path To Net Zero

Designing and building net zero homes is Rountree Architect's passion. The short film titled: “A Path to Net Zero”  features a home they had the privilege to work on in Westport.  


The film was made by my Mr. Rountree's son, Ben Rountree, who is a cinematographer, under a grant from the Connecticut Architectural Foundation, with partial sponsorship from UniLux (windows) and Mitsubishi (heat pumps). 


Buildings produce 40% of the greenhouse gases that cause global warming. This film makes a powerful statement for the need for net-zero homes in light of the recent catastrophic climate events.  


They recently entered the film in an AIA Film competition and it was selected as one of the finalists.

The scientific community is clear that the effects of man-made CO2 emissions on the environment are creating havoc around the world.  Because buildings account for 40% of the CO2 emissions, architects have a responsibility to change the way they are built to reduce or eliminate their "carbon footprint". 


Rountree Architects is steadfastly committed to change the way buildings are designed and to mitigate their negative impacts.It is now possible and economically feasible to create buildings that are “Net-Zero” in terms of their energy use. Net-Zero buildings are able to generate all the energy they use with on-site solar PV systems.  Net Zero homes are healthy homes. They have excellent indoor air quality and are resistant to mold growth. Net-Zero buildings have a positive impact on the environment, and are now more economically feasible than ever before.
