Designers, owners and operators are all faced with a myriad of decisions on how best to achieve their building design and operational goals. Complex and often conflicting objectives can make even the simplest decisions appear challenging. Take, for example, thermal comfort. According to the Department of Energy, adjusting temperature set points by just one degree for an eight-hour workday can save commercial building owners 3% in energy costs. This equates to thousands of dollars in savings each year. Clearly, the least costly alternative is to not heat or cool a building.
