Most people have worked in an office with poorly regulated temperature, where it seems that whatever the weather is outside, its the same inside. The office also probably had terrible fluorescent lighting, a severe lack of windows, and the ability to waft the terrible smelling tuna someone brought as their lunch throughout the building. These buildings were all designed to cram as many people into a building as possible without regard for how the office environment would turn out. For some design professionals, this does not make sense which is why they are turning towards WELL Building certification.
