Office workers across the United States are experiencing uncomfortable cold temperatures at their desks, a problem that stems from both building design choices and how cooling systems operate. Property managers typically set thermostats to the low 70s Fahrenheit during summer months, but actual comfort varies dramatically depending on proximity to air conditioning vents, building orientation, and system efficiency.
The root cause involves the ASHRAE 55 thermal comfort standard, which uses equations based on metabolic rates and clothing insulation to calculate optimal temperatures. These calculations assume an average metabolic rate of 100 watts per person. The standard also factors in air velocity and mean radiant temperature from windows and walls. Buildings designed around this single baseline create winners and losers across floorplates.
Several structural factors amplify the problem. Buildings with exterior glass walls experience higher radiant cooling from air conditioning units positioned to blast directly at workstations. Older HVAC systems lack zone controls, forcing uniform temperatures across entire floors despite variable occupancy and sun exposure. Corner offices facing west absorb afternoon solar heat, while interior spaces near AC ducts become frigid. Many commercial real estate properties operate on decades-old systems that were never designed for modern open-plan office layouts or hybrid work schedules.
The cost of retrofitting aging HVAC infrastructure deters action. Upgrading to smart, zone-based systems that adjust temperature by area requires capital expenditures many property owners avoid. Meanwhile, occupants layer clothing or use space heaters, creating secondary inefficiencies and energy waste.
Remote work has worsened the issue. Buildings designed for full occupancy now run cooling systems at partial capacity, creating dead zones and uneven temperature distribution. Facility managers lack granular data on actual office utilization, so they maintain broad cooling patterns for spaces that sit mostly empty.
The problem compounds during peak summer months when demand for air conditioning spikes. Building owners face pressure to reduce energy consumption while maintaining tenant satisfaction. Some have implemented occupancy sensors and variable air volume systems, but adoption remains limited across the commercial real estate sector.
Investors in commercial real estate should watch operational efficiency metrics closely. Building productivity directly correlates with tenant retention and lease renewals. Properties failing to address thermal comfort issues risk higher vacancy rates and reduced valuations.
