Additional goals for the home included “seamless integration into its historic setting, meeting Not So Big House principles because of the site’s modest footprint, and minimizing energy used by the home to lighten its carbon footprint.”

ZED’s holistic approach to design was a natural fit for meeting the project’s health goals since allergies and chemical sensitivities can be impacted by materials selected during the process of designing, building and furnishing a home. ZED worked together with Aedi Construction and K Tharp Design to select materials that do not emit irritating gases.

ZED designed a radiant heating system for the living areas on the first level, while the bedrooms on the second level received hot water radiators. To complement the hydronic heating, an energy recovery ventilator with HEPA filteration provides a constant supply of fresh outdoor air.
