Building heating represents a substantial cost for most homes, municipal, and commercial buildings in Stow. Heating with fossil fuels can also be a source of unhealthy indoor air pollutants as well as a major source of greenhouse gas (GHG) emissions. In fact, a greenhouse gas inventory of Stow showed using fuel oil, natural gas, or propane for building heating and hot water is responsible for over 40% of total town GHG emissions.
Buildings in Stow, including homes and municipal buildings are making steady progress in reducing heating costs and GHG emissions through energy efficiency measures such as insulation and air sealing and by retrofitting some or all of the building heating requirements to use electric heat pumps. However, large new housing developments are planned for Stow over the next several years and it is important that this new construction not add to our townwide GHG emissions.
As a result of the state’s 2021 climate legislation, a new building energy code was introduced called the Specialized Energy Code. The goal of the Specialized Energy Code is to ensure energy efficient new construction and help achieve the state’s greenhouse gas emissions limits. The Code is opt-in and Stow was the 16th community in the state to adopt it at the spring town meeting in 2023. The Code went into effect in Stow in January 2024. As of the start of 2025, there are 55 communities which have adopted the Code. For Stow, the Specialized Code is part of the town’s overall energy and climate goals as described in the Stow Climate Action Plan and adopted by the Select Board.
While the use of fossil fuels such as fuel oil, natural gas, or propane, is not prohibited for new construction under the Specialized Code, it is discouraged through a number of provisions. These provisions are intended to ensure the building is energy efficient, offsets the GHG emissions of a new building using fossil fuels, and prepares the building for the future removal of fossil fuel appliances. The impact is to increase construction costs as compared to all-electric construction. The builder is also disqualified from receiving incentives from our utility available for all-electric new construction.
Stow is particularly well suited for fossil fuel free new construction having both among lowest cost and cleanest electricity in the state. Not only will all-electric new construction benefit the builder, it will also benefit the homeowner, and the town as a whole. The estimated savings for heating a new all-electric home as compared to a propane heated home is about $1,000 per year. And for the town, the greenhouse gas reduction is about 5,000 pounds of CO2 per year.
Going forward, new constructions statewide will not use fossil fuels. There are ten communities that have banned the use of fossil fuels for new construction. Prospective home buyers will expect new homes to be fossil fuel free to avoid the future cost of retrofitting to all-electric.
Stow strongly encourages developers to build all-electric new housing.
