To properly regulate the climate in a school building, it is necessary for the building to have a combination of air conditioning and central heating. Option B, ceiling fans, may provide some circulation, but they are not sufficient on their own to maintain a consistent temperature. Option C, solar powered heating, may be a more environmentally friendly choice, but it may not be able to provide adequate heating for the entire building. Option D, natural ventilation, may be useful in some cases, but it is not a reliable method for controlling the temperature and can be affected by outside weather conditions. Therefore, the most effective and reliable option is to have both air conditioning and central heating installed in the school building.
