It is only fitting that we talk about heat as we approach the summer months and brace for what could be a sweltering and sweaty summer. It is important to address heat gain, something we have already touched on, and several other factors relating to heat in the summer. Our window manufacturing glossary term for the day is in keeping with this very idea. Heating degree day is our term, and we’re sticking to it! A heating degree day is essentially a term used by those in the heating and cooling industries to describe the climate conditions of different regions and areas and how those conditions relate to the amount of energy required to heat or cool a building. The concept works from a base temperature of 65 degrees Fahrenheit. A heating degree day is basically a day in which the temperature falls above or below the baseline. For example, a temperature of 50 degrees Fahrenheit would be considered a 15 heating degree day day. The language gets a little messy, but the concept is simple. The hotter or colder it gets, the greater the measure of heating degree day.
This concept is very useful when looking at what kind of windows are appropriate in different regions across the country. A common misconception is that you can take a one size fits all approach to outfitting a house with windows. Unfortunately, climate must play a significant role in the decision process if the proper window is going to be found. Fortunately, however, there are a lot of resources to help determine best fit. Terms like heating degree day can help identify regional specifics that are important to be aware of before purchasing windows. There are also a lot of knowledgeable people in the window manufacturing industry who can help ease the decision making process and identify the strong points and weak points of any given window.
