Meeting developing code requirements to reduce carbon emissions while creating environments with better IAQ will challenge and impact conventional building HVAC system designs.

Passive radiant heating and cooling system designs exploit the properties of all heat transfer modalities for enhanced system efficiency and healthier built environments. 

Increasing the amount of outside air to the occupied space and increasing ventilation air change rates are effective solutions for reducing concentrations of contaminants and the risk of infection.

The technologies to reduce pathogenic infections exists — so why aren’t we using them?

In our previous article, “Debunking Myths of Active Chilled Beams: What You Thought You Knew – But Were Wrong, Part 1,” engineers from SmithGroup and Dadanco, along with senior sales engineers from Varitec

Chilled beams offer building owners greater energy efficiency, reduced building first cost, reduced day-two maintenance, and improved indoor air quality.
