Whether truly historic or simply old, each legacy building presents unique challenges and opportunities for repair, preservation, and adaptive re-use. Understanding the design standards from when it was built, and changes that have occurred during its long service life are essential to charting a sustainable path forward. Conservation and re-use is an inherently sustainable practice; embodied energy in existing buildings limits the environmental impact of procuring new materials, and thoughtful application of contemporary building science principles can substantially improve performance and greatly reduce operational energy demands.
Avoiding undesirable side effects is also critical; modern interventions can go awry without a thorough understanding of existing building envelope performance. CTLGroup’s deep understanding of historic and modern construction materials, our state-of-the-art in-house laboratory and analytical capabilities, and history of in-situ assessment and monitoring form the basis for the development of practical solutions to complex engineering challenges that preserve the architecture of the historic cityscape.
