Concord Green Home Featured in Houzz

ZED’s classically beautiful, healthy, and ecofriendly Concord Green Home was just featured in a Houzz editorial article on ‘sustainable homes created by design professionals for themselves’.

The residence was created for interior designer Lisa Tharp who wanted a home that not only blended in seamlessly with the traditional New England architecture in the Concord, Massachusetts, neighborhood, but also offered the highest indoor air quality and a low carbon footprint. Multi-functional living spaces such as the first-floor home office that could also serve as an ADA-compliant master suite or the alcove off the second-floor master bedroom that could work equally well as a secondary office space or a walk-in closet ensured that the home met the needs of the family and would also appeal to future homeowners.

The home won the EcoHome Design Award in 2011 and has been previously featured in Fine HomeBuilding and Design New England magazines.

ZeroEnergy Design Submits 2018 Data for AIA 2030

2018_AIA-2030 Data.jpg

ZeroEnergy Design recently submitted project data for 2018 to the AIA 2030 Design Data Exchange, reporting an impressive 92.6% reduction in pEUI savings across its architectural portfolio. Last year, ZED reported an 88.7% reduction and was one of the only 10 firms nationwide that achieved the AIA 2030 goal of 70% pEUI savings across their entire design portfolio.

The AIA 2030 Commitment program supports the AIA 2030 challenge, which calls for all new buildings, developments, and major renovations to be carbon-neutral by the year 2030, and offers architects a way to publicly show their dedication and track their progress.

Since 2010, architectural firms in the Commitment have been tracking and evaluating the performance of their design projects over each calendar year. The data, collected via the 2030 Design Data Exchange (DDx), includes the type of building, area, baseline energy performance, and predicted energy performance. In 2017, 2030 Commitment participants saved 17.8 million metric tons of CO2, which is equivalent to the carbon that would be sequestered by 21 million acres of forest.

ZED’s continued commitment to sustainable design and energy efficiency is reflected in its excellent year over year performance. This is the ninth consecutive year the firm has achieved the targeted 70% carbon reduction.

The 2018 Summary is expected to be released during the summer of 2019. In the interim, the 2017 report is available.


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.


New Case: Modern Oceanfront 'Forever Home'

ZeroEnergy Design is pleased to release a case study in exceptional green modern architecture and mechanical design: the Dartmouth Oceanfront Residence in South Dartmouth, Massachusetts.

Nestling within a coastal New England setting, this modern home takes advantage of the site’s natural topography and stunning ocean views - providing the homeowners with the perfect home to entertain in style, showcase their love for art, and enjoy comfortable low-carbon living.

A super-tight building envelope, carefully-designed HVAC systems, and concealed exterior shades lower energy consumption and ensure year round thermal comfort, while a photovoltaic system on the roof generates almost enough energy to offset the home’s energy consumption. Covered outdoor spaces, charging ports for electric cars, and accessibility features add to this ‘forever home’ that will allow the owners to comfortably age in place.

The project won a PRISM Gold Award for Best Single Family Home at the 2018 Annual PRISM Awards Gala.


Treehugger Story on Chicago Passive House Performance During Polar Vortex

Top sustainability website, Treehugger, recently published a story on how the Ellis Passive House in Illinois, Chicago, performed flawlessly during the polar vortex event of 2019, maintaining consistent indoor temperatures of >71 F with minimal increase in kWh demand, thereby proving the inherent resilience of the Passive House standard. Mike Conners of Kenwood Construction Services, the builder on the project, had earlier published a detailed report on the resilience and efficiency exhibited by the Ellis Passive House in the face of the extreme weather conditions.

The Ellis Passive House was originally constructed in the 1890s. It underwent a thorough renovation for modern, green living with ZeroEnergy Design acting as the Certified Passive House Consultant and mechanical designer for the project. It is the first PHI Certified Passive House in Illinois and exemplifies the possibilities of passive house retrofits for older residential masonry buildings in urban settings.


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.
