Abstract

sues of building science, which are related to thermal performance of building envelopes. Five years ago, the Journal if Thermal Insulation added the phrase &dquo;building envelope&dquo; to stress the role of thermal insulation in the construction system. Despite the name change, this Journal remained the leading publication in the field of thermal insulation, reporting scientific advances and technical developments. The expansion of the scope helped to consolidate the vision and improve the Journal’s profile. The construction industry undergoes slow but continuous change. Stress is placed on quantifying performance of the whole building system, rather than on that of individual products and components. Objective-based codes and performance-oriented standards are more commonly used. A cost benefit analysis replaces many of the prescriptive recommendations. In this situation, one may argue that expanding the scope of the Journal to:
