12 CORE Principles for Healthy Building Design
CORE Principle 04
Climate Control, Ventilation & Indoor Air Quality
Healthy indoor air requires much more than adding an air purifier.
HVAC, ventilation, filtration, humidity, exhaust, pressure relationships, source control, and the building enclosure must function together.
SENERGY360 helps establish indoor air quality objectives and works with the mechanical engineer and HVAC contractor to coordinate those requirements with the home.

SENERGY360 helps guide:
- Heating and cooling load calculations
- Proper HVAC sizing
- Duct design and distribution
- ERV/HRV and controlled fresh-air ventilation
- High-efficiency filtration
- Kitchen exhaust and makeup air
- Bathroom and laundry exhaust
- Humidity and dehumidification
- Condensate management
- Building pressure relationships
- Attached-garage pollutant control
- IAQ monitoring
- Airflow and ventilation commissioning
Indoor monitoring may include:
- PM2.5
- CO₂
- VOC trends
- Relative humidity
- Temperature
- Carbon monoxide
Healthy air is designed—it is not created by a single filter or air purifier.
One of 12: Climate Control, Ventilation & Indoor Air Quality
Every principle is stronger when the other eleven are in the room.
SENERGY360 coordinates all twelve from early design through final verification.
