[12] Improving energy efficiency can affect fire safety

During the past 10 years, energy efficiency in buildings was widely promoted by authorities at various levels. This was done without much consideration regarding technical installations (e.g. electricity). It was certainly not a good approach to just increase the thickness of wall insulation without at least a control of the technical installations. This tweet from 2010 was visionary because fire safety is now strongly integrated in the 2018 edition of the Energy Performance of Buildings Directive.
