The invention provides a method for controlling the climate of an environment, e.g. a house, which exchanges thermal energy with an ambient space. Energy is supplied to the environment e.g. by radiators, floor heating, electrical heating fans etc. According to the method, a numerically expressed comfort criteria, and a numerically expressed weight of importance of compliance with the comfort criterion are defined. Subsequently, a supply of a specific amount of energy is considered, and with respect to that amount, a numerical expression of a degree of compliance with the comfort criterion, and a numerical expression of costs related to the supply of that amount of energy are provided.
