![]() ![]() Results of the condensation risk analysis are available as summary or in more detailed form. Printouts with Diagrams and Graphical Illustrations The interior climate is defined by choosing any one of five predefined humidity classes, which describe the building’s normal use:īuildDesk U performs monthly calculations of the moisture build-up or evaporation within constructions, with results being displayed in a user-friendly manner. You also can also input your own climate data for any other location. All you need to do is click on the location nearest to your project. ![]() The BuildDesk climate database contains exterior climate data, certified by the Met Office, from more than 60 locations across the United Kingdom and the Republic of Ireland. Changes to the design in the U-value calculation automatically update the condensation risk analysis so that the effect of any modifications can be seen immediately Exterior Climate Data Certified by the Met Office If a potential risk is indicated the design can be reconsidered and if necessary modified to minimise the risk. Use the software to simply check your U-value calculations for condensation risk. The BuildDesk U software performs Condensation Risk Analysis according to the BS5250 and BS EN ISO 13788 standards and assesses the risk of both surface and interstitial condensation occurring for different constructions. Recent health scares from ‘toxic mould’ growth in buildings have also highlighted the dangers that may be caused if condensation persists. Condensation can give rise to a range of problems from surface staining of internal finishes to long term degradation of the structure. With increasing levels of insulation, the use of impermeable cladding materials and new methods of construction, can often come increased risk of condensation in buildings. Extensive database.īuildDesk > Software > BuildDesk U > Condensation risk Condensation Risk Analysis Tool Easy-to-use and graphically oriented for the fast assessment of building elements. The calculations used to determine the CRF rating are based on the procedures outlined in AAMA 1503-09, Voluntary Test Method for Thermal Transmittance and Condensation Resistance of Windows, Doors and Glazed Wall Sections, an FGIA standard.Includes Condensation Risk Analysis (CRA) and heat capacity calculation for assessing thermal mass. Rate and amount of water vapor released to interior.Water vapor pressure and temperature outdoors.Water vapor pressure and temperature indoors. ![]() Location of surrounding buildings and type of surrounding terrain.Positive exterior wind pressure or negative pressure within the building which may increase infiltration of cold air.Depth of reveal (recess at stool, jambs, and head).For cavity walls, location of thermal barrier in the product with respect to the wall cavity. ![]() Type of wall construction and material(s) used therein.Conditions which may affect interior surface temperatures include (but are not necessarily limited to) the following: Thermal conductivity of surrounding building construction, interior/exterior trim, humidification control, and the method of heat distribution on the interior plane of the assembly will impact its overall performance. Condensation in the field can be a result of many variables. wall sections versus operating windows or versus fixed glazing). Some interpretative allowances may need to be made in comparing products of dissimilar type or configuration (e.g. It will provide a comparative rating of similar products of the same configuration and permit the determination of the conditions beyond which an objectionable amount of condensation may occur. While not an absolute value, the CRF is a rating number obtained under specified test conditions to allow a relative comparison of the condensation performance of the product. The CRF Tool is intended to provide general guidance on suggesting a minimum Condensation Resistance Factor ( CRF) based on a project-specific set of environmental conditions. ![]()
