Reduce summer HVAC expenses and keep employees happy
Ask the Expert: Q: Our upper floors in our building are difficult to keep at a comfortable temperature when the weather gets above 80 degrees F. How can we keep our employees more comfortable in the upcoming summer?A: On a warm sunny summer day, your roof surface temperature can reach in excess of 130 degrees F. This heat can easily transfer to the interior of your building making it difficult for your air conditioning equipment to keep up.Most buildings have roof top mounted HVAC systems that take in the surrounding outside air, which is super-heated due to the hot roof surface. The system then conditions this very hot air to a lower temperature to control the temperature in the interior of the building. Because of this your HVAC equipment works harder, costs you more money, and can experience difficulties in maintaining the desired temperature on all floors.
An energy efficient reflective roofing system can keep your building cooler and save you significant money in cooling costs. Protective roof coatings are highly reflective (85%) and can keep the surface temperature of your roof within five degrees of ambient air temperature resulting in a cooler roof surface and a more efficient HVAC system, as well as reducing bleed-through of heat to your upper floor. Combining highly reflective roof coatings with insulating sprayed polyurethane foam can double your savings by making your building cooler in the summer and warmer in the winter.
