Modeling and experimental validation in partially wet conditions of an air-to-air heat recovery exchanger | 2011 | English
Nowadays, important efforts are deployed to reduce our current residential building consumption. The most common retrofit option concerns the air tightness and the thermal insulation improvement.
A combined simulation of the building envelope and the plant equipment is more realistic than simulating both separately and has the advantage that the modeler can use one software environment instead of multiple software environments.
Effect of heat discharge by natural ventilation on indoor environment and heat removal structure | 2011 | English
At present, for energy conservation, conscious utilization of natural ventilation is encouraged. However, the relationship between heat discharge through natural ventilation and heat loads has not been clarified yet.
Integrated dynamic electric and thermal simulations for a residential neighborhood: sensitivity to time resolution of boundary conditions | 2011 | English
The sensitivity to time resolution of boundary conditions is studied for dynamic integrated simulation of thermal and electrical networks of a net zero energy residential neighborhood.
Energy performance of passive school buildings – an analysis of building properties and boundary conditions | 2011 | English
To evaluate the requirements for passive school buildings, simplified calculation methods based on EN ISO 13790 are used.
One trend in whole building simulation is the incorporation of hygric interaction of room and enclosure. This allows besides a more detailed comfort assessment the optimization of building components to avoid moisture related damage or failure.
Thermal environment prediction using CFD with a virtual mannequin model and experiment with subject in a floor heating room | 2011 | English
For the surface temperature of clothing, body surface temperature, and detailed temperatures and heat flow phenomena of soles contacting the floor, results of measurement experiments using human subjects were compared with results of simulations c
Modeling for building energy performance improvement in accordance with the local climatic settings: a case of a generalizable building design of intermediate health care facilities in Thailand | 2011 | English
This study aims to conduct an Integrated Building Design process (IBD), collaborating a Building Information Modeling (BIM) application with a Building Energy Simulation tool (BES) to perform energy analysis, and improving the building energy perf
This paper proposes to study the role and the user in the operation of the building and its impact on energy performance of buildings.
Zero emission building envelopes - numerical simulations of a well-insulated building with phase change material panels integrated in the floor | 2011 | English
In this paper, numerical building energy simulations were carried out with weather data for Karasjok, Stuttgart and Seville, to evaluate the energy saving potential of a floor with integrated PCM panels.
CFD and PIV based investigation of indoor air flows dominated by buoyancy effects generated by human occupancy and equipment | 2011 | English
This paper describes the full scale tests for air flows in a test chamber subject to heat loads generated by human occupancy and equipment.
Thermal simulations on the effects of vegetated walls on indoor building environments | 2011 | English
A simulation study was undertaken to assess the effects of vegetated walls on the thermal performance of a building.
Comparison of measured and calculated values for the indoor environment in one of the first Danish passive houses | 2011 | English
Energy savings in the residential area are essential in order to achieve the overall goal for energy savings outlined in the recast of the Energy Performance of Buildings Directive. This was adopted by the European Parliament in 2010.
Performance of a daylight redirecting glass shading system demonstration in an office building | 2011 | English
This paper evaluates the daylighting performance of a prototype external dynamic integrated shading and light redirecting system. The demonstration project was carried out on a building with an open-plan office.
Analysis of impact of selected glass units for energy consumption and the risk of overheating in the school building using simulation | 2011 | English
The insulation glass unit as a part of a window plays a key role in the design of low energy buildings.
Energy performance comparisons for a given building acquired using measurements and simulations obtained during annual operation in Slovak climatic conditions | 2011 | English
The paper presents a comparison of the simulation results and measured operating parameters of building in Slovakia. Attention is paid to the overall energy performance of the building during annual operations.
As the solar thermal system with the floor heating and the hot-water supply system need low temperature of 40-50 degC, the effectiveness of solar collector is high.
Quantification of retrofit measures on a multi-family residential building for different European climates with detailed and simplified calculation tools | 2011 | English
In an international simulation study, the measures to be taken with an example retrofit building at different locations were quantified in order to reach the energy demand goal of 30 to 50 kWh/m2 a of primary energy for heating, ventilation and do
Underfloor air distribution integrated with an indirect and direct evaporative cooling assisted 100% outdoor air system | 2011 | English
The purpose of this paper is to evaluate the energy conservation potential of an underfloor air distribution (UFAD) system integrated with an indirect and direct evaporative cooling assisted 100% outdoor air system (IDECOAS) in hot and humid clima
