Deep energy retrofit

A deep energy retrofit is a process that makes older buildings more energy efficient. Buildings can use a lot of energy to heat, cool, and light them. By doing a deep energy retrofit, people can save money by using less energy, while also making their buildings more comfortable in the summer and winter.

To do a deep energy retrofit, people should first find out how their building is using energy. This can be done with a special tool that measures how much energy your building is using. Once you know how much energy your building is using you can look for ways to make it more efficient.

For example, you'll probably need to insulate your walls, roof, windows, and floors more. This stops cold air from coming in during winter and hot air from coming in during summer. Also putting in new, energy efficient heating and cooling systems (like air conditioners, furnaces, and air source heat pumps) can help save energy. You should also try changing your light bulbs to LED lights, which use less energy.

Finally, saving energy is important, but so is saving water. You can do this by adding low-flow faucets, showerheads, and toilets.

By doing all of these things, you can save energy and money on your energy bills, while making your building more comfortable.
