Thermal Bridging in Building Envelopes
For existing buildings , retrofitting with additional insulation, thermal breaks, or high-performance materials can help alleviate the identified thermal bridges. Thermal bridging is a significant challenge in building envelopes that can compromise energy efficiency, increase costs, and affect the occupant comfort of a building .
Thermal bridging consequences worsen as other building envelope components become more insulated [6], [7]. Building envelopes commonly suffer from thermal bridging due to changes in building geometry, such as extended balcony boards, slab edges, and interfaces between building assemblies.
Thermal bridging in buildings
The increasingly stringent energy and emission targets have made thermal bridging a critical consideration for building construction. Thermal bridging is excessive, localized heat flow through discontinuities in the insulation layer, such as at window and door assemblies, building envelope junctions, or balconies, that significantly increases space-heating and cooling demand, depresses ...
Based on published literatures, various types of building thermal bridges are discussed in this paper, including the most effective solutions to diminish their impacts.
Thermal bridging assessment improves building envelope design by reducing heat loss, preventing condensation, and supporting accurate energy modelling.
In determining the thermal performance of the building envelope that includes thermal bridging , a basic distinction must be made between two types of opaque building components, clear field assemblies and interface details, examples of which are shown in Figures 1 and 2 respectively.
