|Health and Indoor Air Quality
With a specific focus on indoor air quality, this home employs a new ventilation and air filtration system, helping to make it a safe and comfortable environment for its occupants. The state-of-the-art fresh air system includes a Zehnder 350 HRV, Zehnder ComfoPost inline heating/cooling coil, and HEPA air filtration system. This system allows for fresh, filtered air to enter the home throughout the day and to be increased when needed, such as when the kitchen hood fan is drawing smoke out of the kitchen during cooking. This fresh air system maintains high indoor air quality by reducing particulates in the air, even when the outdoor air quality is particularly poor, such as during a summer forest fire.
Built with passive and active solar needs in mind, this two-story house faces south. Triple-paned Vinvltek windows on the south side provide passive heating and natural light within the home. White interior paint also helps provide significant daylighting and reduces energy demand from the home’s LED lighting.
The home also employs a 12.87kW photovoltaic system, producing enough power to make the home net positive and power an electric vehicle. With a shell system constructed from 6.5” SIPs walls, 10.25” SIPs roof, 4” foam under the slab-on-grade, ICF form slab-edge stemwalls, and U 0.18 average triple pane windows, this house has a tight envelope, helping to reduce energy consumption.
The three-bedroom, two bath house is meant to allow the occupants to age in place. The first floor has a kitchen, main living space, a bedroom and bathroom, and ADA-compliant doorways.
Overall, this home is a comfortable, clean, net positive building, allowing the homeowners to be happy, healthy, and confident in the knowledge that their home is serving their needs, meets a high standard of excellence, and is protecting the environment in the process.
