Condensation Risk Analysis

Bespoke Condensation Risk Modelling & Analysis

We can provide condensation risk analysis to BR443 for both Surface and Interstitial condensation. These are usually required where their is a perceived risk based on the proposed construction specification.

Risks are usual associated where breaks in the continuity of insulation (cold spots / thermal bridges) occur, complex material relationships, poor detailing and specialist sheet and rainscreen cladding systems.

What is Surface Condensation?

Surface condensation usually occurs when insulation is reduced or lacking in part of a building fabric element such as a wall, floor or roof. This cold spot within the construction can allow for the rapid change in temperature of usually a highly conductive material such as a steel beam which come into contact with warm air. This leads to the production of moisture vapour condensing which forms as water droplets known as condensation on a cold surface.

 

Common areas include:-

  • Steel framed buildings

  • Timber framed buildings

  • Warm roofs

  • Flat roofs

  • Basements walls

What is Interstitial Condensation?

Interstitial condensation usually occurs when water vapour builds up in a building fabric element usually via design has no prevention or ability to self evaporate. This leads to the production of moisture vapour condensing which forms as water droplets known as condensation on a cold surface.

 

Common areas include:-

  • Steel framed buildings

  • Timber framed buildings

  • Warm roofs

  • Flat roofs

  • Basements walls

 

Don't forget! Use our New Build Pack service to save money and hassle by combining your SAP, EPC, Air Permeability Testing, Extract Ventilation Testing, Water Efficiency Calculation and Acoustic Testing (if applicable) all together.

New Commercial Buildings

We can provide EPC's for new commercial buildings in accordance with Part L2a of the building regulations which require all new commercial buildings to provide the building control officer with a copy of an energy performance certificate EPC prepared by an “non-domestic energy assessor” (NDEA) prior to building control completion and final sign off.

 

The EPC is generated by using the SBEM Calculation, if you have used BEAT Solutions to prepare your SBEM calculation, this will enable a quick production of your EPC as we already have most of the information ready and to hand.
