Working on Ventilation in Humid Climates w/ HAVEN
Kevin Hart from HAVEN returns to the podcast to talk about ventilation in humid climates and some best practices for working on systems that focus on the V in HVAC. HAVEN focuses on IAQ management with the use of software technology.
HAVEN started off with its central air monitor, and the company then developed a central air controller to help customers make their homes healthier. Fresh-air ventilation is one IAQ, but humid climates make it tricky to bring that air in; dumping “fresh” air into the structure without taking extra precautions can lead to high indoor humidity and even microbial growth.
ERVs, HRVs, and ventilating dehumidifiers are some traditional ventilation strategies for various climates; exhaust ventilation is also quite common but can pull hot, humid air through the building envelope. HAVEN is creating a more templated approach to ventilation; HAVEN uses whole-home in-duct monitoring and local weather data to get ideas of the conditions inside and outside the home to tailor fresh-air ventilation to each individual system’s needs.
HAVEN has partnered with several ventilating dehumidifier manufacturers, including Santa Fe and AprilAire; many of these manufacturers also use filtration to control the quality of incoming fresh air.
Kevin and Bryan also discuss:
- HAVEN’s journey during the COVID-19 pandemic
- Chemical interactions in our homes (VOCs and CO2)
- Exfiltration and infiltration
- The problem with industry standards and regulations
- Appropriate climates for ERVs, HRVs, and ventilating dehumidifiers
- Using dew point to control indoor and outdoor parameters
- Energy savings with HAVEN’s technology
- Does a house need to “breathe?”
- HAVEN app
