Abstract
The methods of dynamic optimization are applied to develop control strategies for a passive solar heated residence. The residence has an electric heater imbedded in a concrete floor so that off-peak electricity can be used to supplement the solar heating. Several optimal control strategies which depend on some form of weather prediction are presented including one which will minimize the energy cost. The barious strategies are compared using simulations of the residence thermal performance. The effects of errors in weather prediction are bounded by comparing simulations using perfect weather prediction and a tomorrow will be the same as today prediction.
