There are several key differentiators between our new Unity Homes and other standard homes built to code on the market, including the design, adaptability, Open-Built processes, off-site construction and prefabricated building. But anyone can SAY their homes are better. We’re backing it up with actual building science.
Recently Bensonwood Assistant Project Manager and Energy Analyst, Rheannon DeMond, who studied Architecture and Building Science in college, produced a Building Shell and Energy Consumption Comparison based on a Unity Home plan compared to other shells that can be found in the industry.
You can read the full two-page report here but to sum it up: Unity Homes outperform several of what the industry considers to be well-built, high performing homes – in a number of heat and energy categories. And keep in mind this is a standard Unity Home.
The Building Shell and Energy Comparison uses the Varm 113 Building Shell, and compares it to the Average New England Home, 2003 IECC Home, 2009 IECC home, 2012 IECC Home and an Advanced Thermal package.
The Baseline Unity Home consumes less energy than all other code building shells modeled, and only uses fractions more than the Advanced Thermal Package that has been used to achieve Passive House Standards in the New England area. The Energy Comparison confirms the benefits of heating with an Air Source Heat Pump, which results in an estimated 50% reduction in Annual Heating Costs. Lastly it reveals the predicted payback period for Solar Electric Systems over a thirty year period, while emphasizing the importance of a solid thermal envelope and air tight building shell.
To produce the Energy Comparison, Rheannon created a complete Energy Model of the Baseline Varm 113 home if it was situated in Portland, ME. After she obtained all of the performance numbers for that Building Shell, she used the same building footprint and location to model different versions of the International Energy Code Shell Specifications. Once she had modeled the performance numbers for all of the building shells she graphed the information to show how a Baseline Unity Home compares to the rest of the industry.
The numbers are impressive, and we continue to adapt and improve the design and performance of these homes. We’re on a mission with Unity Homes. Join us – sign up to receive Unity and Bensonwood news.
