Hybrid Ventilation

In Canada both residential and commercial buildings often require intensive ventilation and air-conditioning to maintain occupant’s thermal comfort and indoor air quality during the operational hours in cooling season. One way to reduce the cooling load consumption is utilizing mixed-mode cooling approach for space conditioning through natural ventilation. This paper presents the potential of control strategies for motorized window opening schedules to reduce the cooling load for a library building that was designed to be net-zero in terms of annual energy consumption (Canada’s first institutional net-zero energy building in Varennes (near Montreal), Québec, Canada). Even though the building is located in cold climate zone, the performance study shows that the building is cooling dominated i.e., it has more cooling load than heating load. To achieve net-zero energy building status, the potential of mixed-mode cooling approach (natural ventilation combined with mechanical ventilation) during the cooling season needs to be investigated. Preliminary simulation results show that the mixed-mode cooling could achieve 10 to 20% energy savings based on hybrid ventilation (HV) with fixed schedules, whereas 65% savings based on HV with variable schedules. This paper also shows 47% reduction of cooling load could be achieved by applying shading control strategies over without shading control strategies.

Natural Wind

Hybrid ventilation is a two-mode system, including mechanical and natural ventilation, which can be used in large space to exhaust excessive heat while minimize energy consumption. One mathematical model is developed to calculate indoor vertical temperature distribution by the hybrid ventilation. Here, the mathematical model is proposed to illustrate the running operation of the hybrid ventilation, especially the control strategies of the natural ventilation in this paper. An experimental and theoretical investigation of natural ventilation in the hybrid system in an atrium building has been conducted. A simplified approach for calculating critical outer temperature and a mathematical model of the natural ventilation in the hybrid system are both proposed in this paper. We have restricted our attention to the natural wind within the upper zone of the large space, in which the effects of the outer air temperature, indoor heat, the natural air rate, and the inlet location of the natural wind are discussed by the mathematical model and experimental data.
