Which construction period typically describes tighter building envelopes?

The construction period that typically describes tighter building envelopes is post-1970. During this era, there was a growing awareness of energy efficiency in building design. As energy codes were introduced and updated, builders began to incorporate more insulation, more effective sealing techniques, and energy-efficient materials. This led to the construction of tighter building envelopes, which help in reducing energy loss and improving overall building performance.

Building practices evolved considerably after the 1970s in response to the energy crises, which prompted architects and builders to consider how air leaks and thermal performance could be minimized. The result was a significant shift towards creating structures that were more energy-efficient and better insulated. As a result, understanding this trend is crucial for those involved in commercial drying and restoration because working with tighter building envelopes impacts moisture management and drying strategies.
