ABSTRACT
Proper integration of all passive strategies as it regards sustainability will be a giant stride to optimizing energy usage in building with absolute mechanical dependant. Passive Design regards the particular way to construct a building using the natural movement of heat and air, passive solar gain and cooling in order to maintain a good internal comfort. Usage of passive strategies in the building sector enhances sustainability measures predominantly through mitigating building’s negative environmental impacts besides optimizing its energy performance. Building a passive home takes careful planning, which includes the introduction of five Basic principles: Orientation, Overhangs and shadings, Insulation, Double or triple glazing, Thermal mass, Through the use of passive solutions it is possible to mitigate, or at least reduce, the use of mechanical systems and the energy demand by a measurable percentage as well as the CO2 emissions. The aim of this paper is to avoid solar radiation, promote ventilation from the prevailing wind and ensure daylight into the building. This journal however demonstrates the importance of an alternative usage of energy in buildings as it regards the sustainable building through careful analysis of related journals, articles, and books. The study is useful for various resource persons involved in construction activities who wishes to imbibe all strategies for the achieving an eco-friendly building.
Obsolescence is commonly regarded as the beginning of the end-of-life phase of buildings. Sources about the life cycle of buildings show a variety of terms. The building and development trade commonly refers to the development cycle, consisting of the development phase, including the design and the construction phase, and the usage phase, consisting of the actual use and the reuse or end-of-life phase (de Jonge and Arkesteijn, 2008). Sources regarding the life span, building pathology and mortality of buildings more often refer to the physical life or real life, being the period of physical existence, including the usage and end-of-life phase. This is in line with most national building stock statistics that in general only state withdrawal from the residential stock, in some countries subdivided by withdrawal by demolition and/or disaster, merging with other buildings and loss of function (Dol and Haffner, 2010).
