Saint Paul, MN

Picture
Client Needs:
  • Family members require high indoor air quality and comfort to manage health issues.
  • Owners purchased an existing home to be remodeled to meet family needs.
  • Dated home lay-out doesn’t meet current and future family needs.
The Solution:
  • Passive House quality homes provide supreme indoor air quality, high comfort, are extremely durable and healthy homes.
  • Most wood frame homes are ready made for retrofitting to Passive House quality.
  • Simply remove existing dated roof and wall finishes, windows and doors.
  • Add a continuous air/vapor/moisture barrier and thick insulation layer over the existing home exterior within supplemental wood framing. Install Passive House quality windows and doors.
  • Continuously supply exterior fresh air, remove interior stale moist air, scavenge waste energy with a recovery ventilator, then HEPA filter supply air distributed to primary living areas. 
The Result:
  • The family lives very comfortably in sunlight washed rooms with high indoor air quality.
  • Living spaces flexibly fill existing client needs and are adapatable for future goals from growing children to aging-in-place and back.
  • The semi-open kitchen connects to the open living and dining areas which connect directly to the southern outdoor deck cooking, dining and living area.
  • The flexible library/office doubles as a  guest bedroom and future master bedroom.
  • The kitchen, laundry, master bath, children’s bathroom and water heater stack tightly over each other, minimizing piping cost, water usage and hot water heating energy.
  • The all electric home is solar-ready. Solar panels to be added later to partially offset electricity usage.
