- Energy efficiency is one area that scientists are focusing on to decrease the worlds overall energy use
- Energy efficiency in buildings is one of the top priorities in energy conservation
- There are many different ways that we can make an older building more energy efficient
- Simple ways to improve a building’s efficiency
- Insulate and Plug Leaks
- Use energy-efficient windows
- Stop other heating and cooling losses
- Heat living and working spaces more efficiently
- Heat water more efficiently
- Use energy efficient appliances and lighting
- Cut off electrical devices when not using them
Auditing Energy Efficiency
- In order to determine if a building is energy efficient or not, we use an energy audit.
- Professional companies will take exact measurements and specific details about how energy efficient a building is
- We will conduct a simpler, more qualitative analysis of both the school and your home
- We will be looking at the following criteria for energy efficiency:
- Light bulbs
- Room temperature and heating
- Room dynamics
- Appliance Use
- Fluorescent bulbs are much more energy efficient than incandescent bulbs.
- Fluorescent bulbs cost more, but save money in the long run
- A simple way to improve the energy efficiency of a building is to switch all light bulbs to fluorescent bulbs
Windows and Doors
- If you feel/detect air moving underneath or between windows and doors than heat is also being lost or gained through those cracks.
- Drafty windows and doors are considered inefficient and energy wasting
- Intense sunlight needs to be blocked from entering rooms during summer months and allowed to enter during winter months
- This helps lower the dependency on heating and cooling by electrical devices
Room temperature and heating
- The temperature that a room is maintained at tells a lot about the energy efficiency of that room
- Room temperature is on average 22°C. A room is colder/warming than that is wasting heat energy (either through loss or by over heating/cooling)
- Having the ability to control the amount of heat (or air conditioned air) that is entering a room helps to improve efficiency.
- A room that is under automatic heating control is energy inefficient, because its temperature cannot be adjusted to reflect the weather outside
- Obstructions to heating vents block air from circulating (and heating the room) requiring more energy to be put in to regulate the room temperature
- Carpeting and floor covers make a room more energy efficient by conserving heat
- The higher the ceiling is in a room, the more energy is lost trying to heat the room all the way to the top. Hot air rises so a room is in fact heated from top to bottom
- Computers require a large amount of energy
- Turning them off when they are not in use is a big energy saving practice
- New appliances have been modified to save on energy. Older appliances tend to require large amounts of energy and waste a lot of it
- Newer appliances all have blue “efficiency” stickers which indicate how much energy they save
