Why Modern Offices Keep the Thermostat Too Cold

Step into a modern office building in July. You might need a heavy sweater. Outside, the temperature reaches thirty degrees. Inside, the air conditioning runs at twenty. Workers shiver at their desks, wearing wool cardigans while summer sun beats against the glass. This contrast feels bizarre. Why do office managers keep thermostats so low?

The answer begins with a surprisingly old formula. In the 1960s, scientists created a standard to measure thermal comfort. They based this formula on the metabolic rate of a resting forty-year-old man weighing seventy kilograms wearing a traditional three-piece suit. This profile represented the typical office worker of the mid-twentieth century.

Workforce demographics changed completely over the following decades. Millions of women entered corporate offices. Today, office populations include diverse ages and body types. Yet facility managers still rely on that sixty-year-old male standard. Research shows that men and women often have different metabolic rates. Women generally produce less internal body heat than men. A temperature comfortable for a man in a heavy suit often leaves a woman in lighter clothing feeling freezing.

Another factor is clothing norms. Men's business attire traditionally involves multiple layers: undershirts, dress shirts, jackets, and trousers. Women's summer office clothing often features lighter fabrics and fewer layers. When the thermostat is set for the heavier male uniform, female employees freeze.

Building design also plays a role. Modern skyscrapers feature sealed glass facades. They trap solar heat effectively. To prevent the core of the building from becoming an oven, powerful centralized cooling systems run constantly. Facility managers often set temperatures low to satisfy the warmest zones, usually areas near sunny windows or crowded conference rooms. Workers sitting near central vents suffer the consequences.

Some companies try to compromise. They encourage flexible dress codes or provide communal blankets. However, changing the central thermostat remains difficult because of building regulations and complaints from employees who run warm.

Next time you reach for your office sweater, remember you are wearing clothing suited for a mid-century businessman.
