1973 The 1973 auditorium addition has several primary construction components that comprise the building’s exterior envelope; this includes roof, walls, floor, and glazing. Each of these constructions are appropriate to the time they were constructed, but do not meet current construction standards or code requirements. Exterior upgrades are recommended for multiple parts of the 1973 building that would remain. The roof is metal deck over steel roof framing with 2” of insulation. Additional insulation should be added to create a minimum R30 roof. Roof insulation should be continuous up and over the cap connecting to the wall.
The walls are typical standard weight CMU with 1” exterior insulation and a brick veneer rainscreen. Additional insulation should be added to meet a minimum R20 wall composite. Existing glazing systems are aluminum storefront with 1” insulated glass. The existing system should be looked at on a case by case basis for moisture infiltration, both through the system and into the IGUS ‘s. If moisture or fogging is discovered, replacement is recommended. Ideally all glazing systems should be curtainwall or thermally broken for superior drainage and thermal performance. Glazing should meet the minimum SHGC,
