It’s the time of year when thermostats and energy bills go up. When it comes to heat loss in buildings and offices, the most common culprit is windows. In many commercial buildings, a large portion of the surface is often windows, where heat loss can become a major issue with a huge impact on demand and cost.
When it is warmer inside than out and a building’s envelope isn’t properly sealed, heat loss will occur. This heat transfer will occur through any openings in the building–HVAC vents, outlets, roofs and especially windows.
With the rising cost of electricity and fuel, extreme heat and cold can have a significant impact on energy demand and costs. HVAC upgrades are one potential solution, but are costly and don’t solve the real issue–the windows. Energy replacement windows are another option and while they do reduce demand, it can be a long time before there is a ROI on the investment in replacement windows; using large amounts of capital for small returns can easily burn through money that can allocated to other projects or investments in a business.
A solution to this is supplemental windows, which are interior windows that install behind existing windows. At a fraction of the cost of replacement windows or HVAC upgrades, systems like those in the Thermolite Window Systems can provide immediate ROI and energy cost savings.
