Our auditing process consists of:
-
A complete inspection of the house and envelope
-
Tests for insulation, air leakage, and ventilation to find problem areas and leaks
-
Evaluation of HVAC systems and appliances
-
Recommendations for the best course of action to remedy any issues

Passive House
Passive building is a set of design principles for attaining a rigorous level of energy efficiency while also creating comfortable indoor living spaces.
Passive house designed buildings follow 5 building-science principles:
​1. Continuous insulation throughout the entire envelope without thermal bridging
​
2. Airtightness to prevent infiltration of outside air and loss of conditioned air
​
3. High-performance windows and doors.
​
4. Balanced heat and moisture-recovery ventilation
​
5. Minimal space conditioning
