AIR AND VAPOUR-TIGHT OSB FOR TIMBER-FRAME BUILDINGS

摘要

Passivhaus is a low-energy performance standard that can be applied to many building types, from homes and care homes to schools, hotels and supermarkets. It is intended to reduce the energy demand for space heating and cooling, while creating excellent indoor comfort levels. This is primarily achieved by adopting a "fabric first" approach to the design, with very high levels of airtightness, increased levels of insulation and reduced thermal bridging, and the use of mechanical ventilation with heat recovery.
