High-performance building.

Beyond the checklist.

Sustainability requires durability, field execution, and measurable operating value. As a leader in green construction services, Domus has delivered some of the most ambitious projects in the region, including Paseo Verde, the first LEED ND Platinum project in the U.S. We understand the rigorous detailing required for energy-efficient building construction, regardless of the certification you're pursuing.


  • Certified TradesWe employ Certified Passive House Tradespeople who understand the science behind the assembly.

  • Mock-UpsWe build and pressure-test full-scale window and wall mock-ups before mass installation begins.

  • SequencingWe carefully schedule trades to ensure air barriers are installed, inspected, and protected before they're covered.

  • Air Tightness TestingWe conduct preliminary blower door tests early in construction to catch leaks while they're still accessible.

Performance is in the details.

High-performance buildings fail or succeed in the field. A single gap in insulation or a torn air barrier can compromise the entire system..

Practicing what we preach.

We apply the same high-performance standards to our own home. When Domus relocated, we viewed the renovation as an opportunity to demonstrate the value of sustainable systems. Our headquarters serves as a living laboratory for the technologies we install for our clients.

  • Solar Energy: We use two distinct solar grids: one that feeds back into the electrical utility and a second array that charges battery backups for our emergency lighting systems.
  • Water Conservation: A grey water system captures rainwater from our roof, repurposing it for landscape irrigation and restroom fixtures.
  • Envelope & Efficiency: We reduced our load requirements through spray foam insulation, highly insulated windows, and strategic skylights that maximize natural daylight.
  • Smart Controls: All lighting and plumbing fixtures are high-efficiency and use occupancy sensors to eliminate waste when spaces are empty.

Balancing cost and compliance.

Balancing cost and compliance.

Many owners fear that sustainable construction means blown budgets. We help you navigate the "green premium" by identifying the most cost-effective strategies to meet your goals.

  • ROI: We prioritize upgrades that lower long-term operating costs (insulation, air sealing) over purely aesthetic green features.
  • Incentives: We assist in documenting compliance for utility rebates and tax credits.
  • Durability: High-performance envelopes reduce the risk of mold and moisture damage, protecting your asset value.
