In this section seven different types of components have been compiled (external wall, internal wall, compartment wall, etc.) which are further sub-divided into 42 basic design types (external wall with or without ventilation, external wall with or without dry lining, etc.). Variations of these designs can be created by modifying for example the thickness or the type of insulation material.

For each component and its variations, performance parameters regarding thermal, acoustic, fire and ecological performance levels 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 or accepted research institutions.

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. 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, etc.) or a performance parameter (REI30, U>0,21 W/m²K, etc.). If the identification code of a particular component is known, then it can be entered directly into the search field on the starting page (e.g. awrhhi04a-00).

Detailed information on building materials (layer composition)

Values for the thermal conductivity λ and the specific heat capacity c, the water vapour diffusion resistance µ and density ρ have been quoted with the standard EN ISO 10456 or from the respective product standards.

(NOTE: Building materials must be used with these corresponding (design) values).

The fire resistance classes have been quoted according to the decisions of the European Commission or from the respective product standards.

Detailed information on the evaluation of ecological performance levels

The declaration of ecological performance levels of building materials is based on the database of baubook. This online library is managed from baubook GmbH which is held in equal parts by the Energy Institute Vorarlberg and the Austrian Institute for Building and Ecology GmbH (IBO - Österreichisches Institut für Baubilogie und -ökologie GmbH). With the used computer software eco2soft, the environmental indicators of different building materials were sourced from the database and allocated on the multiple layered construction elements. One m² of component surface is used as the basis for the calculation.

The database uses information about building materials, shared from manufacturer. Before implementing of that information in the database, the details, especially proven material data (regarding building physics and ecology) is controlled by the baubook quality control.

All building components from dataholz.eu have been edited and calculated in eco2soft, according to their specified layer thicknesses and volume fraction of the relative layers. Most building material data are adjusted, and manufacturer neutral. This can lead to slight variations between the proposed general information and manufacturer specific information.

Life Cycle Assessment (LCA)

The assessment of environmental impact of buildings is based on ÖNORM EN 15804, which regulates the boarders of the system. As there are large variations in the building materials, transport routes, use phases and disposal for each building, for the dataholz.eu components only the ecological assessments of the manufacturing phase are available. This phase in the product life cycle (A1 – A3) consists of raw material extraction (A1), transport to the manufacturer (A2) and manufacturing (A3). Material, transport, energy, waste as well as emissions to air, soil, water are determined for each of these process steps. The system border describing the manufacturing phase only, is called “cradle to gate”.

Used standards:

ÖNORM EN 15804:2020 Sustainability of construction works – Environmental product declarations – Core rules for the product category of construction products

Ecological performance levels

The following ecological indicators are given for each building component:

ΔOI3-Indicator for a layer of building material
Global warming potential (GWP)
Acidification potential (AP)
Eutrophication potential (EP)
Ozone depletion potential (ODP)
Photochemical ozone creation potential (POCP)
Primary energy renewable, energy resources (PERE)
Primary energy renewable, material (PERM)
Primary energy renewable, total (PERT)
Primary energy non-renewable, energy resources (PENRE)
Primary energy non-renewable, material (PENRM)
Primary energy non-renewable, total (PENRT)

ΔOI3

The calculated ΔOI3-Indicator (spoken: Delta-OI3) is a useful parameter for rapid detection and optimization of “ecological heavyweights” and is calculated via following formula:

When:

(PEIne)_BS…non-renewable primary energy of the component layer in MJ/m²

(GWP)_BS… Global warming potential of the component layer in kg CO₂ äqui./m²

(AP)_BS… Acidification potential of the component layer in kg SO₂ äqui./m²

GWP

A parameter in the form of the global warming potential is defined for the most common greenhouse-active substances relative to the leading substance carbon dioxide (CO2). The greenhouse potential describes the contribution of a substance to the greenhouse effect, relative to the contribution of an equal amount of carbon dioxide and is given in the unit kg CO2 equivalent.

AP

Acidification is mainly caused by the interaction of nitrogen oxide (NOx) and sulfur dioxide gases (SO2) with other components of the air, such as the hydroxyl radical (OH). The measure of the tendency of a component to become acidic is the acid formation potential. It describes the contribution of each acid-forming substance, relative to the acid formation potential of sulfur dioxide, and is given in the unit kg SO2 equivalent.

EP – Eutrophication potential

The eutrophication potential indicates the contribution of a substance that contains nitrogen or phosphorus to the supersaturation of the soil. This contribution is given relative to the contribution of the same amount of phosphate in the unit kg (PO₄)^3-.

ODP – Ozone depletion potential

The ozone depletion potential is used to evaluate substances that break down the stratospheric ozone layer and are therefore responsible for the so-called ozone holes in our atmosphere. These substances are generally referred to as chlorofluorocarbons (CFCs). This contribution is given relative to the ozone depletion potential of trichlorofluoromethane (a refrigerant with the abbreviation R11), with the unit kg CFC-11 equivalent.

POCP – Photochemical ozone creation potential

By mixing nitric oxides and hydrocarbons, photochemical reactions take place under the solar radiation, which creates reactive, health-damaging reaction products such as ozone. These gas mixtures arise, for example, from exhaust gases from traffic, industry and incomplete combustion.

The potential for formation of tropospheric ozone is stated in life cycle assessments as the ethene equivalent in the unit kg C₂H₄ equivalent.

PERE – Primary energy renewable, energy resources

The renewable primary energy content (as an energy source) is the required energy demand, needed for the production of the product/service of energetically used resources (from biomass). The lower calorific value of the resources in MJ is used as unit.

PERM – Primary energy renewable, material

The renewable primary energy content (as a raw material) is the required energy demand, needed for the production of the product/service of materially used resources (from biomass). The lower calorific value of the resources in MJ is used as unit.

PERT – Primary energy renewable, total

The renewable primary energy content (total) is the required energy demand, needed for the production of the product/service of materially and energetically used resources (from biomass). This characteristic value is formed from the sum of PERE and PERM and is indicated by the unit MJ.

PENRE – Primary energy non-renewable, energy resources

The non-renewable primary energy content (as an energy source) is the required energy demand, needed for the production of the product/service of energetically used resources (petroleum, coal, etc.). The lower calorific value of the resources in MJ is used as unit.

PENRM – Primary energy non-renewable, material

The non-renewable primary energy content (as a raw material) is the required energy demand, needed for the production of the product/service of materially used resources (petroleum, coal, etc.). The lower calorific value of the resources in MJ is used as unit.

PENRT – Primary energy non-renewable, total

The renewable primary energy content (total) is the required energy demand, needed for the production of the product/service of materially and energetically used resources (petroleum, coal, etc.). This characteristic value is formed from the sum of PENRE and PENRM and is indicated by the unit MJ.
