Includes bibliographical references (p. 24).
The existing windows of the 90-year-old buildings on the main MIT campus are not energy efficient and compromise comfort 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 would not compromise the historical significance of the existing windows. The design and prototype demonstrated the replacement's functionality and preservation of aesthetic quality. The analysis showed an expected decrease in energy consumption of more than 70% and cost savings of nearly $2 million a year. The analysis also showed that comfort levels are higher throughout the year.

<Abstract>The existing windows of the 90-year-old buildings on the main MIT campus are not energy efficient and compromise comfort 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 would not compromise the historical significance of the existing windows. The design and prototype demonstrated the replacement's functionality and preservation of aesthetic quality. The analysis showed an expected decrease in energy consumption of more than 70% and cost savings of nearly $2 million a year. The analysis also showed that comfort levels are higher throughout the year.</Abstract>
