EBOSS and the BIM Acceleration Committee are pleased to announce the findings of the sixth year of the BIM Benchmark Survey. 

This month we look at 'airtight' vs 'breathable' building. Is it possible to achieve both within the same build? 

The use of energy-efficient glass delivers a more comfortable building interior and helps reduce energy costs across the service life of the building. 

With the growing acceptance that we must be much more clever with our use of the world’s non-renewable resources, we are well past the time when we can rely on long-standing assumptions, short-term thinking, and Green-wash. Objective assessments are urgently needed.
