Application of advanced glazing to high-rise residential buildings in Hong Kong

The energy saving that can be achieved by applying advanced glazing to a typical high-rise residential building in Hong Kong was evaluated using the simulation software EnergyPlus. It was found that application of low-e glazing would lead to a reduction in cooling electricity use by up to 4.2%. The saving due to application of low-e reversible glazing would be up to 1.9%; double-clear glazing up to 3.7%; and clear plus low-e glazing up to 6.6%. The achievable saving would depend on orientation of building wings, and type and location of rooms. The analysis suggests that for the high-rise public housing blocks in Hong Kong, the use of expensive advanced glazing would not be economically viable from the point of view of saving in cooling energy cost.

Impact of control rules on the efficiency of shading devices and free cooling for office buildings

To develop low-energy architecture, designers need knowledge about passive cooling techniques and shading devices. This paper focuses on the impact of management strategies for external mobile shadings and cooling by natural ventilation. Various control rules are simulated for both techniques. Resulting energy demand and comfort conditions are discussed. For shadings, strategies based on both internal temperature and solar irradiation set points are shown to be more efficient than strategies based on solar irradiation or internal temperature alone. For natural ventilation, strategies limiting the flow rate when outside temperature exceeds internal temperature are found to have no major impact on comfort conditions for the Belgian weather. A flow rate limitation when external temperature drops is found to be efficient to save energy. Objectives of this paper are to show that management choices have a real impact on energy and comfort criteria and to help designers to choose the adequate management rules for their projects.

On the efficiency of night ventilation techniques applied to residential buildings

Climatic change and heat island effect in combination with the non-proper design of buildings have increased substantially the cooling load of buildings. Night ventilation appears to be one of the more promising passive cooling techniques. Many important theoretical and experimental studies have been performed however the existing information is presented in a segmented way. The present paper analyses energy data from two hundred fourteen air conditioned residential buildings using night ventilation techniques. The specific absolute energy contribution of night ventilation has been calculated. The relation of the cooling demand of the buildings with the specific contribution of night ventilation has been investigated. It is found that the higher the cooling demand of the building, the higher the potential contribution of night ventilation under specific boundary conditions. The role of air flow rate is investigated as well. It is found that the global utilisability of the energy stored during the night increases as a function of the air flow rate and the tilt of the regression line between the energy contribution and the air flow rate increases significantly with the air flow rate applied, although the energy contribution per unit of air flow is decreasing. The whole analysis contributes towards a better understanding and evaluation of the expected energy contribution of night cooling techniques.
