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]

The roads are the dominant mode of transportation in India today. India has dubious distinction of nation with about 8-10% towards road death which is nearly one lakh every year. Pavement surface quality is a primefactor which enhances the serviceability of a road. Pavement surface quality is spoken in unevenness and assessed in terms of the automobile wheels movements and suspension arrangement along with the drivers' understanding of speed and acceleration. Though, notwithstanding the rapid high-tech advancement of high-speed roughness checking apparatus, it should not be ignored that highway pavements are constructed for the drivers, who have ever been keenly aware of the relative degrees of ease or distress felt in traveling. Mostly, travellers believe in three basic things from the pavement surface; even trip, sufficient resistance to slipping, and enough power to shift the traffic to the following section of the highway configuration. Hence their insight on road surface quality should also be considered. In this case study an attempt has been made to maintain the roads by monitoring the roughness of road surface whether they exist in good, average or poor condition at specific reach of Chandigarh city in India.

Generally new constructions go on remote areas to develop where there are no means of transport, medical facilities, first aids, security by the contractors in sufficient numbers and a huge number of helpless, low paid laborers reside there on spot of construction. So these construction sites are very much vulnerable to the terrorists‟ attacks. Recently number of terrorists‟ attacks on constructions in progress and existing both drew the researchers and designers attention. In this research 18 Indian construction organizations were surveyed and it was investigated that most of the companies were performing well in overall safety measures needing little improvement to reach to the excellence but in terrorism management before, during or after completion of the project leaving a few construction companies rest were lagging behind as revealed by considerable R2 value (0.754) with trending linear equation of which positive vertical intercept (0.6931) showing only first three companies taking care and negative slope (-0.0462) of line shows terror management failing in most of the companies surveyed. This research will not only enrich the construction project management domain but will be an alarm to governments and for safety of constructions before, during or after completion of projects also.

Confusions in different land conditions in normally delicate Quartzite rock regions represent various issues for architects and organizers to go through for development exercises particularly the development of Hydro Power Plants. This paper clarifies that how the complete geotechnical examination program attempted at the site guides in battling the topographical varieties and intricacies to guarantee the achievement of solidification grouting performed at Power Tunnels viz. Head Race Tunnels, Tail Race Tunnels. The information about the presence of discontinuities like flaws, deficiencies, gaps, number of weak zones, exceptionally changing topographical conditions with over trouble of thick vegetative cushion which presents danger to development exercises in delicate quartzite rock mass should be surveyed prior to undertaking the Consolidation Grouting activity. Solidification Grouting under high tension is normally led to make up for shortfalls in rocks and to combine the stone mass around the fringe of passages so the delicate stone mass around the passages should act as a solid construction and become impermeable. The porousness tests are then led to dissect and survey the productivity of combination grouting. This paper uncovers how the different geographical tests embraced at site not just assistance the designers and organizers in keeping up with noteworthy improvement in porousness esteems in delicate quartzite rock mass around the head race burrows yet additionally help in setting aside cash, labor and material.

Energy consumption has become the challenge especially in developing countries such as India and China. In recent times, increasing fears about the environmental impressions of energy consumption and global warming has exaggerated this concern. The building sector is consuming one-fourth of the share at state level power consumption in Punjab where the procurement of coal even becomes the challenge and thermal plants needs to be stopped leading to almost blackout in the state. This paper examines the energy saving conformations leading to reduction in energy management of the building. To achieve this, a residential building is modeled in Design builder software and simulation is carried with Energy Plus integrated tool. In this paper, simulation were carried out with variety of double glass formations with infill material such as argon and air in gap of 12 mm. Full year simulation was performed for the composite climate. Simulation results indicated the considerable reduction in solar gains by 28.28% and cooling load by 27.08%. Further, initial assessment was carried out by calculating approximately the cost of double glass unit and payback period for different window formations. It is recommended to use the double glass unit empanelled window formation which has the potential to reduce the electricity bill considerably. The initial cost is approximately 2.12 times more than traditional window which be offset by the savings over energy consumption. [ABSTRACT FROM AUTHOR]

Due to number of parameters effect with varied variety in energy of the building, it is difficult to judge about the effect of different energy efficacy approaches without simulation implements. The study focus on the annual energy consumption of an residential building simulated in Design Builder software utilizing efficient double glazing window formation with respect to traditional window. The building is in composite climate and window to wall ratio kept is 50%. The authorization of simulation results through electricity records with simulation error in the range of 1.39% - 6.89 %. Two promising strategies are proposed to management for reduction in the energy consumption, first, replacement of traditional glass with low-e double glazed unit having argon gas and secondly by double glazed window formation having air as infill material. The simulations results showed the benefit reap out of these strategies are 36.1 % and 25.04% respectively. Further, economic assessment showed that the payback period for first and second strategy is 1.43 years and 1.73 years respectively. [ABSTRACT FROM AUTHOR]
