Comparison of indoor radon maps obtained with different softwares and methods

The use of two mapping methods, kriging and moving average, in mapping the indoor radon risk, isinvestigated. Both methods are applied to three databases: simulated radon data, data collected inSouthern Belgium with low sampling density, and data collected in Luxembourg. We use commercialsoftware (SURFERR 6) for kriging, as well as softwares developed by the authors, especially for the radoncase, for kriging and for moving average. Simulated data prove to be very useful in this context. Weconclude that kriging as implemented in SURFERR 6 may not be well adapted to radon mapping.

Desarrollo de un software amigable para determinar de la demanda energetica de climatizacion en un edifico

La tendencia en las nuevas normativas energéticas de todos los países pasa por transformar requerimientos prescriptivos en prestacionales, es decir, en lugar de limitar el comportamiento de cada elemento o del edificio en su conjunto, con una serie de val

Use of IEA-SHC Task 21 C Benchmarks to assess performance of lightscape 3.2 in daylight calculations

In this paper, we use the validation test cases initialized within the subtask C, "Daylight design tools", of IEA SHC Task 21, "Daylight in buildings" to assess the accuracy of a commercial lighting software, Lightscape 3.2. We first analyzed the applicability and the limitations of the IEA 21 test cases, and we concluded some directives for validation test cases in order to guaranty its applicability to assess any lighting software.

Fault detection and diagnosis.

The BR E has developed a set of computer-based tools for the management of heating, ventilating and air conditioning systems. How can designers and facilities managers use them to improve the performance of buildings?
