The retrofit of historical facades of the building stock has
grown in importance due to energy efficiency
considerations in the building sector. Along other recent
new construction technologies, aerogel-based plaster
systems with high thermal insulation have been
developed in the past few years by the AEC-industry.
Although still rather expensive, these systems offer
opportunities to insulate highly-articulated historical
facades in compliance with the principles of heritage
protection.
This contribution analyses the effect of the application of
such aerogel-based plasters on historical building facades
in terms of thermal bridges. Thermal bridges are
considered to be of high importance for both the overall
building´s energy performance and the quality assurance
in terms of healthy indoor environment. The latter
includes aspects of interior surface temperatures,
condensation risk, and mould growth. Typical
construction details of historical building facades were
selected based on relevant literature. These details were
analysed and evaluated with the help of a numeric
thermal bridge simulation tool. A set of scenarios
including original state and different retrofit measures
were applied to these details and their effect was
evaluated in view of thermal bridge calculation. This
contribution includes - along with basic information
about the aerogel-plaster systems and related
background - description of the methodology and a
discussion of the results.
