IS 139 Bronx

Originally constructed in 1957, Intermediate School 139 in the Bronx suffered from water infiltration for a number of years due to failure of the brick unit masonry and the curtainwall. We provided a necessary face-lift for this historic example of a 1950s modern school building. The key feature is the 24,000 square feet of high-performance curtainwall.

An extensive energy analysis was performed to determine how long-term energy cost savings could be achieved. A high-performance aluminum curtain wall system and insulated glass replaced the original single glazed system. We incorporated louvered bris-soleil at the south-facing curtain wall fa├žade in order to reduce the amount of glazing area exposed to solar radiation during the summer months and optimizing performance. A difference of 11.5 kBtu/sf a year in sun shading versus no sun shading resulted from this louver system. A conservation of 318,158,310 Btu a year was calculated; this amounts to a savings of 7,521 gallons of fuel a year.
