Anthony Aebi

Anthony Aebi, Netzero HomesAnthony Aebi, his mission has been to build the most energy efficient and resilient homes to last for generations. Since 2007, soon after building his first Zero Energy Home (ZEH), he has been committed to only build any new home to the same standard. Moreover, every home was designed and constructed to meet and exceed an array of voluntary standards including EPA ENERGY STAR, Indoor airPLUS and the USGBC LEED for Homes standards, including the DOE standards, Builders Challenge, Challenge Home and most recently, Zero Energy Ready Homes.

Anthony has been a pioneer in building Zero Energy Homes not just because he was one of the first builders internationally to construct a ZEH in a cold climate in the Hudson Valley area -upstate NY, but because he had the vision that “every” home build in the world should be designed and constructed to Zero Energy performance standards. To that end, Anthony committed himself into building Zero Energy Communities consisting of several residential developments.

Anthony is constantly pushing the envelope in improving his home designs and construction practices. All of his newly constructed homes are built utilizing ICF wall systems, triple pane fenestration, ground source heat pumps, heat recovery ventilation, energy efficient lighting and appliances coupled with rooftop solar photovoltaic systems.

Anthony makes the case that these homes are an economic and environmental solution. As an investment in our future, our communities, all nations and to the world’s future.
