This article gives an overview over the Guideline VDI 2167 'Building services in hospitals – Heating, ventilation and air-conditioning' which is based on the Swiss Guideline 'Heating, ventilation and air-conditioning systems in hospitals (Planning, construction, operation)' of the SWKI 'Schweizerischen Verein von Wärmeund Klima-Ingenieuren'. Other than editorial changes which were carried out w...

In this paper we show that a biologically inspired modelcan be successfully applied to problems of building optimal districtheating network. The model is based on physiological observations of the true slime mold Physarumpolycephalum, but can also be used for path-finding in the complicated networks of mazes and road maps. A strategy of optimally building heating distribution network was guided...

This work is focused on indoor thermal comfort control problem in buildings equipped with HVAC (Heating Ventilation and Air Conditioning) systems. The occupants thermal comfort is addressed here by a comfort zone in the psychrometric chart and the PMV (Predict Mean Vote) index. In this context, three control algorithms are proposed by using only-one-actuator system associated to a heating equip...

The thermoelectric building envelope (TBE) integrates materials with the for active space heating and cooling. advantage of TBE cooling includes its significantly low-profile design no refrigerant use. Although there are existing studies evaluating performance, they were based on limited operating conditions. study aims to experimentally evaluate performance a prototype under various was instal...

This paper presents a freely available Modelica library for building heating, ventilation and air conditioning systems. The library is based on the Modelica.Fluid library. It has been developed to support research and development of integrated building energy and control systems. The primary applications are controls design, energy analysis and model-based operation. The library contains dynami...

A large fraction of energy consumed in households is due to space heating. Especially during daytime, the heating is often running constantly, controlled only by a thermostat – even if the inhabitants are not present. Taking advantage of the absence of the inhabitants to save heating energy by lowering the temperature thus poses a great opportunity. Since the concrete savings of an occupancy-ba...
