Design and prototype of a partial window replacement to improve the energy efficiency of 90-year-old MIT buildings
… levels. The single panes of glass allow too much heat transfer and solar heat gain. In addition, the steel framework has warped due to oxidation and decay of the glazing compound, resulting in air and water infiltration. This thesis explored a feasible solution of a partial window replacement that …

The effects of building envelope parameters on energy performance for high-rise buildings in central Saudi Arabia
… use air conditioning extensively to overcome the heat and achieve thermal comfort. This research analyzed building envelope variables in an existing building in Riyadh, Saudi Arabia, and measured the effect on energy consumption and cooling loads based on ASHRAE 90.1-2019 and LEED guidelines. The …
