This remodel made the house more energy efficient, as well. By replacing all the old windows with composite frame windows with a much lower U-value, upgrading insulation to meet today’s code standards, converting the old space heating to ductless mini-splits, upgrading the water heater to a high-efficiency gas tankless, and air-sealing the house, they were able to make the house nearly 30% more energy efficient than a new code-built house. Beyond the impressive energy efficiency measures, they also replaced the old wood-burning fireplace with a direct vent gas fireplace to keep some of the old charm while improving indoor air quality.
Many of the design choices were made with sustainability and indoor air quality in mind. The new house has no carpet to trap allergens in the home and the prefinished flooring is FloorScore certified. The millwork is solid wood to minimize off-gassing. If, however, there is some formaldehyde off-gassing, the AirRenew drywall will clean the air by absorbing it!
