  • Wall insulation (R-0 to R-13 cellulose)

  • Attic insulation (R-0 to R-42 closed-cell foam)

  • SANCO2 heat pump hot water heater (uses CO2 as the heat pump refrigerant)

  • Incandescent bulbs to LEDs and inefficient appliances to Energy Star-rated appliances.

​

John and Kelley purchased their 1880 2,000 square foot home in 2011. Over the past 12 years they have been renovating the former 2-family rental property to improve the home’s energy performance, comfort, and overall livability. In 2011, the home had no insulation in the walls or attic, old leaky single-pane windows, 2 inefficient oil boilers, incandescent lights, and many air leaks in the building shell. Through the various energy renovations, the home’s carbon footprint has been reduced from 23 tons of CO2 per year to about 4 tons per year. Their goal is to further reduce the home’s carbon emissions to net zero by installing an air source heat pump system to replace the existing gas boiler, and an induction-top stove to replace the existing gas stove. Once the home is all-electric, with no combustion appliances, 100% of the electricity used will be carbon-free, a combination of the on-site solar generation and the MMLD Green Energy program. â€‹
