Tall building design and sustainable urbanism: London as a crucible
Published in Derek Clements-Croome, Intelligent Buildings, 2013
Heron Tower exemplifies the positive scope to meet these objectives. Its critical starting point – appropriate building orientation and the protective south core that shields the office floors from solar gain – are integral to the overall design. Daylight admitted to the floor plates reduces reliance on artificial light, and the building skin facilitates natural ventilation. The interactive façade is triple glazed – with a single-glazed outer pane, double-glazed inner pane and cavity mounted blind for shading. The low iron glass provides high transparency to afford excellent light and views, reduce energy use, and enhance user experience by contributing to spatial quality and the sense of connection to the external realm.

There are a number of ways by which the performance of the basic flat-plate collectors can be improved. One way is to enhance optical efficiency by treatment of the glass cover thereby reducing reflection and enhancing performance. As much as a 4% increase has been reported (Anderson 1977). Low-iron glass can also reduce solar absorption losses by a few percent.

Flat Plate Collectors(FPC) are stationary collectors and consist of glazing cover, absorber plate, insulation layer, heat transfer fluid tubes and other auxiliaries. Glazing may be single or multiple. Low iron glass is considered a good glazing material due to its high transmissivity of short wave radiation (around in a range of 0.85–0.87) (Khoukhi and Maruyama 2005). The thermal and optical properties of FPC were studied and found that the overall performance of FPC was increased by 5.6% at 50°C due to the addition of Teflon film as a second glazing material (Hellstrom et al. 2003). An optimisation analysis of energy and exergy for FPC was done by Farahat, Sarhaddi, and Exergetic (2009), and they found that the exergy efficiency of FPC depends on the incident sunlight flux, optical efficiency, ambient temperature and wind speed.
