|Information on building components|
In the section 'building components', nine different types of building components have been compiled (external wall, internal wall, compartment wall, …). These which are further sub-divided into 42 basic design types (external wall with or without ventilation, external wall with or without dry-lining,…). Variations of these designs can be created by modifying for example the thickness or the type of insulation material.
For each building component and its variations, the performance parameters thermal, acoustic and fire as well as ecological drivers are provided. Each component variation can be downloaded in pdf format and might be suitable for submission to building authorities to demonstrate compliance. All these quoted performance levels have been determined either by testing, calculations or means of assessment by accredited testing institutes.
The published datasheets will be reviewed on regular basis to ensure that the information provided is current and correct.
A facility for detailed searching is available. Building components can be searched using different criteria, for example by selecting a construction method (solid wood construction or timber frame construction, with or without ventilation,…) or a performance parameter, such as thermal, acoustic or fire (REI30, U>0,20 W/m²K, ...). If the identification code of a particular building component (e.g. awrhhi04a-00) is known, then it can be entered directly into the search field on the starting page.
The datasheet of the building component provided in pdf format contains the following information:
Building component designation
Explanation please see nomenclature
Whilst variations of the basic design have been considered in detailing, performance assessment and so forth, the 3D depiction of the component always shows the basic design build-up (reference design –00).
2D-view with legend
Whilst variations of the basic design have been considered in detailing, performance assessment and so forth, the 2D-view of the component always shows the basic design build-up (reference – 00).
Evaluation of thermal, acoustic, fire performance requirements and ecological drivers.
The datasheets provide information on the following parameters:
Detailed information on building materials– configuration of layers
The information provided on building materials such as density, thermal conductivity, specific heat capacity etc. have been quoted from «The catalogue of the thermal performance of building materials and components«, (Austrian Standards Institute, 2001) and, where relevant and available, product standards. Information regarding the water vapour resistance factor µ, originates from «Determination of parameters concerning thermal, acoustic, fire performance as well as ecological drivers for wood and wood-based composites«, (Association of the Austrian Wood Industry, 2002) and for some products have been extracted from test certificates. Information on the Euroclasses of reaction to fire performance have been quoted according to the decisions of the European Commission. The dynamic stiffness s’ and the air flow resistivity r were determined by TGM Institute of technology for thermal and acoustic performance.
Detailed information on the evaluation of ecological drivers
The software ECOSOFT was used to evaluate ecological drivers of the various timber construction elements featured in the database. ECOSOFT is a software tool for the calculation of environmental indicators in accordance with CML 2001 of building designs and construction works based on the IBO database for building materials. ECOSOFT is based on the MS Office application Excel and was developed by IBO – Austrian institute for building biology and ecology.
In ECOSOFT, building elements are assembled from individual layers of different building materials: for each layer the building material is selected from the database and the thickness of the layer and the volumetric share [%] of the building material based on the respective layer is used. The database suggests a density value and service life for the respective building material, these parameters can be modified depending on the product employed
