This RDH Technical Bulletin covers the thermal improvements, improved airtightness, and measured energy savings that resulted from upgrading windows in two 1970s vintage residential concrete towers.
As energy costs for existing buildings continue to increase, solutions are needed to manage costs and energy consumption. Energy upgrades are sometimes implemented to reduce energy costs in high-consumption buildings. This bulletin explores RDH's findings when energy upgrades were implemented in the two adjoining towers of a high-rise multi-unit residential building.
