SIMULATION FOR FA?ADE OPTIONS AND IMPACT ON HVAC SYSTEM DESIGN

摘要

This paper presents a simulation study employed for the optimization of the building envelope for a new university building located in Montreal (latitude 450N). The study involved simulation of fa?ade design options, taking into account maximization of daylight, reduction in electricity consumption for lighting and optimal control of solar gains. Combinations of motorized shading devices in conjunction with controllable electric lighting systems are investigated in detail. Transient simulations also considered the impact of motorized shading and light dimming on HVAC system sizing and energy consumption for heating/cooling. The resulting energy savings and thermal comfort using an optimum design strategy are discussed.
