In this video by the USGBC, former Director of Structural Resources for the Trustees of Reservations, Jim Younger, describes the sustainability philosophy used at the Center for Agriculture and the Environment at Appleton Farms. Both the farmhouse and the west wing on the property underwent a thorough renovation and deep energy retrofit to achieve the client’s desire for net zero carbon energy performance.

ZeroEnergy Design provided energy consulting and mechanical design services for this project.


Greenport Passive House - New Passive House Consulting & Mechanical Design Project

ZeroEnergy Design is excited to present a new Passive House Consulting and Mechanical Design case study - the Greenport Passive House in Greenport, New York.

Designed by the Turett Collaborative, the architect’s decisions regarding the home’s orientation and upside-down layout maximize natural light and passive solar gain in the upper level living-areas. ZED then assisted with consulting for the Passive House-aligned airtight building envelope, continuous insulation, meticulous air sealing, triple-glazed windows, and high-efficiency HVAC and hot water systems - all of which work together to ensure exceptional energy performance, improved indoor air quality, and first-rate comfort for the occupants.

Read the full case study below.


Renovated Paul Rudolph House in Dwell, Energy by ZED

A Paul Rudolph House in Cambridge, Massachusetts, is featured in Dwell magazine after Ruhl Studio Architects renovated the much-loved mid-century home to accommodate the needs of the new homeowners and greatly improve the energy efficiency. As a consultant to Ruhl Studio Architects, ZeroEnergy Design provided energy consulting and mechanical design for the project. The envelope updates and new HVAC system help ensure increased thermal comfort, healthy indoor air, and a smaller operational carbon footprint for the home.


ZED's Jordan Goldman to Present at Fine Homebuilding Summit

In addition to providing a valuable forum for networking and exchange of ideas, the summit will also feature several insightful presentations from industry experts, including ZeroEnergy Design’s Jordan Goldman.

Jordan leads the mechanical design practice at ZED. He is a Certified Passive House Consultant, LEED Accredited Professional, and HERS Rater, and specializes in building envelope strategies, building science design, and mechanical system design, specification, and sizing for enhanced energy performance.

Jordan’s session at the Fine Homebuilding Summit will focus on HVAC for High-Performance Houses.

WHERE: Southbridge Hotel and Convention Center, Southbridge, MA
WHEN: October 2-4, 2019

Preregistration for the summit is currently open. We hope to see you there!


Greenport Passive House featured in Inhabitat

Popular green architecture and home design website, Inhabitat, just published an article on the Greenport Passive House, designed and built by architect Wayne Turett of The Turett Collaborative. ZeroEnergy Design’s Jordan Goldman provided Passive House Consulting and Mechanical Design for this project.

The airtight dwelling was created in alignment with the Passive House standard, which focuses on the building envelope and passive solar gain to achieve exceptionally low energy consumption and operational carbon footprint. In addition to the airtight building envelope and continuous insulation, the all-electric home features a ducted air source heat pump for heating and cooling and an energy recovery ventilation system for fresh, filtered indoor air.


Historic Multifamily Project Case Released

ZeroEnergy Design is proud to present a new case study for the firm’s mechanical design services, the Troy Historic Multifamily Project in the Central Troy Historic District of downtown Troy, NY.

While historic preservation and net zero performance might not seem like a natural fit, this project proves that it is possible to achieve high performance and energy efficiency in older masonry structures without sacrificing the architectural features.

The original Victorian-era structures consisted of two three-story walk-ups in vacant and heavily deteriorated condition. ZED’s responsibilities included specifying and designing efficient HVAC systems that would provide year-round thermal comfort along with a constant supply of fresh air, all with minimal impact on the building’s fabric and historic aesthetics.

Overall, the building achieved a 90% reduction in energy consumption compared to before the renovation.

The project was the result of collaboration between Second Arrow LLC, Neil Pelone Architecture, ZeroEnergy Design, RDH Building Science, LTRW Architecture & Preservation, Ethos Homes LLC, and Active Solar Development.
