In Progress: Cork Insulation at this Providence Net Positive Home

A new net positive, all-electric home is being constructed in Providence's East side, utilizing cork insulation as a component of its airtight enclosure. Cork insulation will help keep the home cool during summer and retain heat during winter, reducing energy consumption and contributing to exceptional indoor air quality.

About Cork Insulation. Cork is a 100% natural and renewable material, made by carefully harvesting the bark of a cork oak tree, an ancient tradition that doesn’t damage the tree. These trees can live between 150 and 250 years and are harvested every nine years - moreover cork tree harvesting actually improves the tree’s health over its lifespan!

Cork is then dried and expanded into cork board through a steam-heat process, requiring no added chemicals or binders during its production. In fact, all byproduct and waste is returned to the production process, making cork insulation incredibly sustainable. The result is a finished product with a negative carbon footprint.

Project Background. This project was conceived as a full time residence for an author who desired open concept living, outdoor connections, and enough bedrooms to accommodate her mature children with their own future families. A music room and craft studio allow the homeowner to explore her artistic pursuits, while an electric cooktop and built-in car charging station make carbon free living accessible.

Location. The residence is located in the Blackstone neighborhood, in the northeast corner of Providence's East Side. The land parcel consists of 18,700 SF of mature grounds and trees, privacy from the road, and a south facing backyard. Several of the client's relatives moved into the neighborhood, creating a sort of urban family compound. Large areas for gathering were therefore a priority, as were open-concept spaces for cooking, dining and entertaining.

  • Indoor and outdoor living spaces

ZED's Net Positive Farmhouse featured in Houzz Earth Day Tour

Popular online architecture and interior design website, Houzz’s tour of seven low-carbon, energy-efficient homes in celebration of Earth Day 2019 features ZeroEnergy Design’s Net Positive Farmhouse in Lincoln, Massachusetts.

With plenty of functional and flexible family-friendly spaces to live, work, play and entertain, a guest suite on the first floor for comfortable aging-in-place, planned rainwater catchment, high-efficiency appliances, root cellar, and edible plantings, this modern home proves that families do not have to compromise on style, space or comfort to live in a healthy, energy-efficient home.

A super-tight building envelope and a well-designed mechanical system ensure that this all-electric home uses 70% less energy than comparable code-built homes, while photovoltaic panels on the roof produce more energy than needed, making it net positive.

ZED and Thoughtforms Corporation designed and built this home in collaboration. The LEED Platinum project won a Sustainable Design Award from the Boston Society of Architects at the 8th annual BSA Design Awards Gala in January 2019. It previously won a Gold PRISM award for Best Net Zero/Passive House and Best Energy-Smart Home from Fine Homebuilding magazine.
