Opportunities and limitations of building precooling.

Author(s) : KEENEY K. R., BRAUN J. E.

Summary

Conventional building cooling strategies largely ignore the thermal capacitance of the structure. Previous simulations and experiments have shown that significant operating savings can be realized when control strategies are used that precool the mass of the building. A detailed simulation tool has been developed to study building precooling. Numerical optimization was used to find the control strategy that minimized daily cooling costs. With some simplifications it is possible to consider the daily cooling cost as a function of precooling to be generated. These results show how building precooling is limited by economic or comfort considerations.
