[Bldg-sim] sources for material libraries

[Julien MARREC]

To expand on what Paul said, ISO 10456 is definitely the most relevant norm at the European level, but there are others that might be of use. Especially if you want to account for thermal bridges without using a heat transfer modeling software such as THERM: you could find a linear thermal bridge coefficient (Psi-value) in EN ISO 10211. Or you want to model ground heat transfer (ISO 13370).

European norms that are relevant to the question are the following (extracted from the French "energy code" (règles Th-U fascicule 4)) 

EN ISO 7345 - Thermal insulation - Physical quantities and definitions

EN ISO 13789 - Thermal performance of buildings -- Transmission and ventilation heat transfer coefficients -- Calculation method

EN ISO 10456 - Building materials and products -- Hygrothermal properties -- Tabulated design values and procedures for determining declared and design thermal values

EN ISO 6946 - Building components and building elements. Thermal resistance and thermal transmittance. Calculation method 

EN ISO 13370 - Thermal performance of buildings. Heat transfer via the ground. Calculation methods 

EN ISO 10211-1 - Thermal bridges in building construction -- Heat flows and surface temperatures -- Detailed calculations

EN ISO 10211-2 - Thermal bridges in building construction. Heat flows and surface temperatures —- Linear thermal bridges

I attached the "envelope performance calculator spreadsheet", where there is a list of all the materials and their properties (in spanish!) in case anyone is interested. IMO the second source most widely used here would be ASHRAE Fundamentals Handbook.

> A source that is slightly dated (1989) but still interesting to read is the report titled: “The Harmonisation of Thermal Properties of Building Materials” by Joe Clarke and colleaques (www.esru.strath.ac.uk/Documents/89/thermop_rep.pdf<http://www.esru.strath.ac.uk/Documents/89/thermop_rep.pdf>). The background was to collect data to extract information on the uncertainty of the material properties as input to uncertainty propagation studies. Another potential source might be the work of Prof. John Grunewald at the TU Dresden on modelling material properties (http://tu-dresden.de/bauklimatik).

> We are currently assembling a material library as a basis for energy simulations and the question came up which source we should use to describe the various thermal and optical properties of  typical construction materials? A natural answer seems to be to use the ASHRAE Handbook of Fundamentals 2009 Chapter 26 which lists such numbers. Are these the tables that “all” of you are using or am I missing an important resource? What about our Canadian, European and other international friends? Would you scorn at an ASHRAE library and rather use your own numbers? This data input is obviously tedious so we want to avoid having to do repeatedly.
