[en] Validation of simulation models appears from a long time as a key issue in order to
promote a more intensive and more efficient use of simulation models in the field of building and
HVAC simulation.
IEA Annex 34/43 originally targeted a number of specific applications where a more
advanced validation was required: ground coupling problems, multizone building, shading, day
lighting and cooling load interaction, HVAC components and ventilated facades. These
validation exercises were built on the large methodological experience obtained in previous
projects and address sometimes very fundamental problems of heat transfer in buildings.
Consulting engineers and practitioners might see these exercises as a bit too far from their
objectives and it is the reason why an additional activity was proposed with the specific aim of
producing, based upon the results of the validation of models, a set of reference simulations.
These applications cover a range of building types (residential, commercial) and systems
(production, distribution emission) and run in a variety of climates.
The paper will describe how models dedicated to these applications were developed,
starting from validation results, going through the selection and consolidation of simulation
hypothesises and ending with a number that might be considered as reference for the concerned
applications. The paper will concentrate on models required by a residential building application
(multizone building equipped with a heat pump or a condensing boiler).
Simulations make use of both EES and TRNSYS software and both software are applied
in parallel as far as possible in the different applications in order to get a better judgment of their
potential advantages and drawbacks. The use of reference simulations in view of qualifying normative methods currently in development in the frame of the European Energy Performance
in Buildings Directive is also addressed and demonstrated in the paper.
