Energy efficiency begins with green design.

green home design plan

We are committed to innovative design that makes life better for our homeowners. We design to save energy, save money and provide a better living environment. Green homes can be both beautiful and comfortable.

Every project is unique and has factors that will influence the design. Smart design is critical at the outset in achieving energy efficiency. Please contact us to learn more about our design services.

Included in our homes

  • We buy our ventilation systems from Fantek.
  • Our solar hydronic radiant heating systems use components from Caleffi and Viessmann.
  • Our homes walls and roofs have R-values up to 70. Our air tightness numbers are to Passivhaus standards of 0.6 ACH 50. Our best air tightness is 0.19 ACH 50.
  • We also use low VOC paints and products for good health for all who are involved.
