The Science of ComfortTM
Since its opening in 1988, Chinook Regional Hospital in Lethbridge, AB, has provided high-quality patient-centered care for the residents of southwestern Alberta. It offers a full range of healthcare services for the region, including a 24/7 emergency department, intensive care unit and extensive outpatient services. According to Alberta Health Services, more than 10,800 surgeries are performed at the hospital every year.

What actually happens when you press the “up” button on the thermostat? What makes the air “hot”? Moving heat in and out of buildings is more complex than simply heating and cooling the outdoor air. While outdoor air is typically preconditioned before becoming primary system air, there is often a need for further cooling or reheating for thermal comfort purposes.

Healthcare-associated infections remain a persistent challenge, with the Centers for Disease Control and Prevention (CDC) estimating that 1 in 31 US patients acquired at least one infection during care in 2024. This reality underscores the critical role of environmental control – particularly room pressurization – in safeguarding both patients and healthcare staff.

As the architecture and construction industries pivot toward energy efficiency and renewability, two innovations are reshaping how we think about building performance and occupant well-being: mass timber construction and underfloor air distribution (UFAD) systems. These technologies work in harmony to create environmentally responsible spaces that are both comfortable to be in and stunning to look at.
