“…To make a full use of hybrid ventilation, field measurement and numerical simulation are often used to study the performance of hybrid ventilation system in buildings. Brohus et al 16 evaluated hybrid ventilation performance in a four-storey office building in the outskirts of the town of Struer, Denmark, by measuring temperatures, CO 2 levels and energy consumptions. Turner and Awbi 17 investigated the thermal performance of hybrid ventilation system and assessed its potential to reduce cooling load through the experiments in a room.…”

Hybrid ventilation is an effective approach to reduce cooling energy consumption by combining natural and mechanical ventilation. Previous studies of full-scale whole-building measurements of high-rise hybrid ventilation are quite limited due to the complexities of buildings and variable ambient conditions. As a result, validated and accurate whole-building simulations of hybrid ventilation often cannot be found in the literature. This paper reports a series of full-scale measurements of hybrid ventilation in a 17-storey high-rise building and associated whole-building simulations by 15-zone detailed and a 5-zone simplified multizone models. The paper is one of the first studies of using multizone models and real-world full-scale data and sharing key operational and performance experience and case studies of high-rise hybrid ventilation. Both the test data and the validated simulation models can be used for the comparison and validation of simulation models. The 5-zone simplified model developed from this study was able to model such a complex high-rise building by only a few zones, making possible the on-line model predictive control of a high-rise building. This was illustrated in this paper by an example of optimizing the uniformity of the hybrid ventilation on different floors by modifying inlet areas.

“…The increase in the impact of climate change on the environment has resulted in the development of hybrid ventilation strategies to provide sustainable indoor climate solutions at the expense of minimum energy use [154], [155]. These hybrid ventilation techniques involve the integration of passive or natural ventilation with mechanical ventilation systems.…”
