“…In zero-energy buildings, the energy produced is stored either as chemical energy in batteries or as thermal energy [1]. However, in a net-zero energy building (NZEB), the renewable energy generated is connected to a two-way grid [2]. The surplus energy generated flows to the grid and when little or no energy is generated, energy flows from the grid into the building.…”

“…It, therefore, provides a chance for energy reduction and carbon emission reduction [4]. Lighting, heating, cooling and ventilation are the major contributors to energy use in buildings, and they hold prospects for energy savings [2]. There are two broad ways of reducing a building's energy consumption -through active or passive means [6].…”

Net-zero energy buildings are buildings that consume less energy than other similar buildings, producing as much energy as it uses or more, from a renewable energy source. Buildings are, without a doubt, one of the key contributors to energy-related emissions. It is important to design buildings that need less energy. Using DesignBuilder, this research explores the potential for net-zero energy in an artificially ventilated single-family dwelling unit in Kuala Lumpur Subang, Malaysia. To achieve net-zero energy five steps are taken; step one involves determining the most energy-efficient glazing, step two involves investigating the most energy-efficient wall material, the next step considers the best window-to-wall ratio, the fourth includes the use of external shading devices and the final step introduces the use of roof installed solar panels. One of the key findings was that shading either through external shading devices or through more efficient glazing reduced the overall energy use and that as the energy needed for cooling reduced as a result of shading the energy needed for lighting slightly increased. The research also revealed that the energy consumption reduced as the wall insulation increased and that bricks/block walls were more energy-efficient than wooden walls without insulation. During the third phase of the research, findings revealed that the energy efficiency of the walls and the windows were the determining factor for which window-to-wall ratio was best. In all, net-zero energy was achieved by reducing the energy consumption by 73.4% and by generating more energy than the building consumes from photovoltaic cells.

This paper proposes an energy efficient solar control film window fixed in glazing system for homes and office buildings. Traditional methods use the films that have less impact on solar radiation. The solar films have the ability to control the radiations and maintain the room temperatures with less energy consumption for cooling. Tiruchirapalli district of tamilnadu state is accompanied by hot climate with heavy heating all through the year. This paper presents an analysis of the solar control film window system fixed in glazing system on a normal and clear window glass in an occupant in Tiruchirapalli (TN). Hence implementing a solar film window in an occupant in tiruchirapalli shows a reduction in the heat obtained by solar radiation with comfortable room temperature and less energy consumption. Furthermore this approach was carried out to control the radiation levels on thermal and effective performance of physically ventilated houses and buildings. Keywords: solar control film window, solar radiation, glazing system, energy consumption, glass coating. I. INTRODUCTIONA solar control film window system works on the principle of minimizing the radiation level of the solar energy that enters through the windows in a home as well as office buildings by gradually increasing the properties of the glazing system either by the method of reflection or absorption. The windows with the neat coatings and the proper films replicate the energy back to the environment and provide additional cooling to the buildings. The solar films are based on the properties of optical with glass technology. These films are mainly developed by means of thin plastic substances that are applied to the inner part of the glass windows. These films will also reduce the effect of visible, infrared and ultra-violet rays since it consists of tints and colours with flat and visible mirror like film. These films are mere identical like the normal glasses. These control films will block the infrared emission of the light more than the normal visible light thereby increasing the cooling temperature of the buildings by providing high visible light transmissions. Some films will absorb the transmitted energy and others will reflect the radiated energy back to the clear environment. Solar films consist of both liquid and plastic applied films. Solar films can be applied by cleaning the window glass and applied the plastic or liquid coating in the cleaned windows. If the solar films are fixed in a professional manner then it will function over a long duration especially between 10-20 years. It is also difficult to differentiate the coated glass with the non-coated one. Improper installation of solar films will leads to peel off or bubbles on the applied coating and also laminating failures will occur. The term solar heat gain coefficient is used to measure the performance of the solar control of the window. The solar energy that is absorbed in the window is normally transferred to the outer surface either by conduction, convection and radiatio...
