Tight envelopes require heavier insulation and sealants as well as energy-efficient windows, but the costs are offset by the money saved on heating and cooling. Unless you live in a perfectly comfortable climate, a tighter envelope is typically a safer bet for contractors. The building can, however, become drafty, and the temperature will be more difficult to regulate. This reduces or eliminates the need for mechanical ventilation, saving money on utilities for the building's tenant, according to Echo Tape. Loose building envelopes allow for more natural airflow, and therefore higher indoor air quality. The looseness or tightness of an envelope is determined by the materials used to construct it. Tight building envelopes restrict airflow to and through its underlying structure, while a loose envelope allows for a freer flow. There are two types of building envelopes: loose and tight.
