Economical societal approach to sustainability for domestic sector in mitigating electricity consumption.

The unmatched construction increase happened in last decade and the domestic construction from late 80s can be labelled as inefficient energy units. Building sector consumes energy more than 54 % and residential sector around 24 % in north region. The rising cost of per unit energy is huge concern especially the cooling loads. The inefficient houses are raising the peak demand becomes a challenge to meet the demand versus generation. This issue must be addressed at micro level. The major energy loss happened through windows (being the crucial component of building services) and more heat inside the building than other components such as wall, roof etc. This paper investigates the possible reasons and gaps that why residential sector is not susceptible towards sustainable windows to lower their electricity bills. The research carried in two phases and questionnaire is framed to gather the data for analysis with aid of experts and literature reviews. It is concluded that awareness of occupant plays a pivotal role in advancement of sustainable windows besides other crucial factors such as orientation, make, glazing type etc. The collective efforts of architect, engineer, vendors and occupant can bridge the gap to reduce energy consumption. The initial cost of sustainable windows can be offset with savings and aid of government policies. [ABSTRACT FROM AUTHOR]
