Adjusting Heating and Cooling
Heating and cooling air in a building through heaters, radiators and air conditioning units requires a tremendous amount of electricity to accomplish. Unless this electricity is generated through environmentally-friendly means such as wind or solar, it will likely have been produced through burning fossil fuels which causes pollution and damages the environment. Raising and lowering the temperature of a room can therefore have serious consequences for the environment and the health, safety and wellbeing of all living creatures. When taken at a global level, this heating and cooling can have dramatic effects on the planet as a whole because of the cumulative effects of the pollution created through this electricity demand.
One thing to keep in mind then is the intended occupancy and activities that are shortly to take place in the room, as this can have massive effects upon the temperature levels and subsequently the amount of heating or cooling that will then be necessary to bring the temperature back to a comfortable level. Forward planning and forethought can play a big part in this achievement. For example, consider a village hall which is heated to a consistent level but knows that shortly it will host a keep-fit session which will fill the room with lots of people who are exercising and so producing a lot of body heat. In this scenario, there is no point in heating the room to normal levels when pretty soon after starting the room will be far too hot and windows will need to be opened to let hot air out or maybe even air conditioning units to be activated. Not only will previously heated air be let out of the windows, but previously heated air may even then need to be cooled down by the air conditioning units! This is a horrible waste of energy which will contribute to pollution levels.
With a bit of forethought and forward planning, the heating level will be greatly reduced or even switched off completely beforehand in anticipation of the keep-fit event. Whilst is may be a bit cold and chilly initially, it will soon heat up when exercising commences and will not require previously heated air to be expelled.
