Our vastly experienced and knowledgeable Energy Consultants can provide PSI-Value Calculations for thermal junctions for residential and commercial projects.
Calculated PSI-Values can be used to help SAP or SBEM Calculations comply with Building Regulations. They can also reduce build costs by removing the need for more costly compliance options.
Psi-Value Calculations are a desk-based exercise that utilise specialist thermal modelling software to determine a building’s overall heat loss at a junction or thermal bridge. There are two types of thermal bridges in buildings: repeating and non-repeating. Repeating thermal bridges, such as timber studs bridging insulation, are accounted for in U-value calculations. Non-repeating thermal bridges occur at junctions between building elements, also known as thermal junctions. These areas often experience significantly higher heat transfer than the surrounding materials and are assessed using Psi-Values.
Psi-Values are used to calculate a building’s overall heat loss at junctions, also known as non-repeating thermal bridges.
Unlike U-Value Calculations, which determine heat loss through thermal elements such as floors, walls, and roofs, Psi-Value Calculations assess heat loss at the areas between these elements. These thermal bridges often result in significantly higher heat transfer than the surrounding materials.
Common examples of thermal junctions or thermal bridges include:
– Window lintels, jambs, and sills
– Door jambs
– Roof-to-wall junctions
– Wall-to-floor junctions
– Building corners
