Identify the requirements
When choosing an indoor climate solution, it is helpful to determine the demand for heating and cooling. It may, for instance, be made by using ESBO simulation software. Once the demand has been established, a solution may be selected and scaled to match the identified requirements.
The Kyoto Pyramid is helpful in determining the sequence of the various measures needed to achieve a good building energy performance. The most energy-efficient method to control temperature is to construct buildings where the demand for heating or cooling does not arise. This is the base of the Kyoto Pyramid. Potential adjustments may be to fit extra insulation and premium glazing in the premises as well as providing the building with a demand controlled sunscreening which can prevent heat loss in winter and excessive heating in summer. Roof eaves which provide shade in summer when the sun is high, but let in light in winter when the sun is low may be seen as another way of demand controlled sunscreening.
