Certified Build homes are grounded in the science-based approach of BSI-145: Zero Energy Ready Homes by Dr. Joseph Lstiburek, Building Science Corporation and Building Science 101 & 201 Build Show Network: Matt Reisinger, Steve Baczek, Brent Hull. This research guides all building assemblies and control strategies for Water, Air, Thermal, and Vapor management in Climate Zone 5, using the 5-10-20-40-60 rule:

• R-5+ windows

• R-10+ under-slab insulation

• R-20+ basement walls

• R-40+ above-grade walls

• R-60+ roofs

Certified Build HVAC systems are engineered by Dr. Allison Bailes team at Energy Vanguard:

• Manual J – Load calculation

• Manual S – Equipment sizing

• Manual D – Duct layout

• Manual T – Airflow distribution

• Ventilation ASHRAE 62.2 – Residential ventilation standards

• ERV System (Zehnder or Lifebreath) for balanced fresh air

• MERV 13 to 16 filtration, with upgrade options to HEPA or UV-C

• Stand-alone whole-house dehumidifier (Santa Fe or similar)

• Fresh air ducted directly to living areas ran through ERV

• Smart IAQ sensors monitor VOCs, CO₂, and humidity
