| Summary: | Smart materials are predicted to ‘revolutionise’ the A/E/C industry. They are supposed to enable a building to change colour, shape, size and opacity. However, past research shows that smart materials are still not used very often in engineering applications to their full potential. In this publication we advocate that materials should not be only chosen for simple properties such as visual, physical and insulating characteristics, but for capabilities such as being able to save/generate energy, store information, and to react to stimuli from their local environment. Therefore, this paper will research into the addition of SolaVeil to a window, its physical configuration and the possibility to model and analyse it through Building Performance simulation (BPS). This material is primarily designed to eliminate glare and redirect light. As a result it can reduce energy use caused by air conditioning and artificial lighting systems. This paper researches into the behaviour of SolaVeil in a computer simulation using two different case studies. The first will compare how changing the width but maintaining the reflective area affects illuminance distribution, and the second will determine which physical properties of SolaVeil are most effective. Finally, conclusions are drawn based on the case studies and it is shown that smaller width light shelves are the most suitable for an anti glare product. It is also determined that for SolaVeil to minimise glare in a room without compromising illuminance levels, it should have a light shelf angle of 40 degrees, cover between 40-60% of a window and its strips should be spaced 5mm. |
