throw this harvested daylight into the room below. This collected sunlight is spread evenly throughout the room by the diffusers. There is more natural lighting because the light shelves, positioned outside the windows of this office, reflect sunlight deep into the room. The high performance solar systems generate about 207,000 kWh of electricity a year which is enough electricity in a year to power 45 four-room HDB flats. This energy is used to run the building’s artificial lights, office equipments and air-conditioning. The solar chimneys are also provided which are specially developed for the tropical climate, made of metal that absorb solar radiation, are placed on the top of the roof or up high in a non air-conditioned room, suck out warm air from the room. Through convection, cool air then rushes into the room. The displacement cooling technique is utilized in which cool air is supplied from the floor level at low velocity and warm air rises towards the ceiling where it is extracted. The temperature of the top floor of the building is reduced by shading the roof from sun with the rooftop gardens. Plants are planted vertically on the walls of the building which shade the walls (Living walls) from the sun and lower indoor temperature (Figure 8). Another section of the ZEB, ‘Office of the Future’ is an actual working office where personalized ventilation system delivers fresh air directly to each occupant’s desk through pipes attached to the desk. The Sophisticated Building Management System automatically controls the various systems in the building to balance comfort and energy efficiency. The facility of automatic light level adjustment is being provided in this office using sensors which measure the light intensity within the office space. When light levels are sufficiently provided by natural light, the artificial light is switched off. The presence of occupants is detected by sensors and the cooling required is supplied accordingly. Figure 8. Different Building Technologies used in ZEB at BCA Academy, Singapore. Thus the ZEB at BCA Academy has a very important role to play in accelerating the greening of Singapore’s built environment. The building demonstrates how an existing building can be retrofitted with green building technologies to achieve energy efficiency and sustainability in the tropical climatic condition. The building is also a test-bedding centre for exciting new
innovations in green building technology before they are promoted for adoption by the building industry. These concepts of ZEB can easily be adopted in the study area to get the similar upbeat results in the field of cost effective, energy efficient building construction as the climatic conditions are similar in both the areas. 5 Result and conclusion To achieve the collective objectives of energy security and environmental protection, ‘zeroenergy building’ should be considered and designed. Due to lack of energy, most of the people are forced to live without lighting and air conditioning facilities in India. The practice of ZEBs, will not only save about 9680.46 billion kWh energy per year in 2030 but also able to fulfil the energy requirements of each and every household (Table 5). The energy efficiency and sustainability in the buildings can be achieved, through incorporating green building technologies in the new buildings, as well as retrofitting existing buildings into ZEBs. Thus, the study concluded with plausible recommendations for constructing costeffective and energy efficient zero-energy buildings in the study area. It is anticipated that, if the proposed model is implemented successfully in the study area, it will ensure sustainable development definitely. References 1. BEE, 2007. Annual Report 2006-07.
