Home Cooling


Indicator: Home cooling needs (in Cooling Degree Days)

What is happening?

Some New Brunswickers use energy to cool their homes during hot periods. Cooling Degree Days (CDD, which indicate how hot or cool a summer is) have been calculated using air temperature information for five communities in New Brunswick: Charlo, Fredericton, Miramichi, Moncton, and Saint John. Saint John has the coolest summers and typically has about 30 CDD; Charlo and Moncton have about 80-120 CDD; while Miramichi and Fredericton have about 140-180 CDD. Across New Brunswick, warmer temperatures are increasing our desire to cool our buildings during the summer months.


Why is it important?

Warm temperatures affect our energy use, public health, and ecosystems. During hot periods, some New Brunswickers use electrical fans and air conditioners to cool their homes. Warm temperatures affect public health in many ways, including impacts associated with food, air, water, infectious diseases, and extreme events such as heat waves. 


What is predicted to happen?

Average temperatures in New Brunswick are expected to continue to increase, and summer temperatures are expected to become even hotter. More New Brunswickers will likely look to cool their homes more during the summer months.
