Building Information Models (BIM) as a facilitator for energy neutral and zero-carbon buildings KU Leuven

Dirk Saelens
Building Physics and Sustainable Design

Building Information Models (BIM) as a facilitator for energy neutral and zero-carbon buildings This PhD-project is a joint collaboration between the University of Leuven and the BBRI (Belgian Building Research Institute) and focuses on the many sources with valuable data that nowadays become available for the built environment such as Building Information Models (BIM). In this research project it is explored how this data can ...

Energy savings in Buildings by combined dynamic thermal simulations and energy management systems Ghent University

Arnold Janssens
Department of Architecture and urban planning

The research project will assess the added value of dynamic thermal simulation models (BES) in the operational phase of a building. Therefore the approach is implemented for 2 office buildings (one in the South of China and one in Belgium) of which the research partners have access to the data of the Building Energy Management System (BEMS). The results of the analysis conducted in the project should be used to improve the energy efficiency ...

Bottom-up engineering building stock models: closing the performance gap using grey-box modelling Ghent University

Jelle Laverge
Department of Architecture and urban planning

The aim of this research is to increase reliability and reduce the performance gap of bottom-up engineering building stock models, by combining a large amount of recently available measured data with available data-analysis techniques. The existing theoretical calculation models will be
updated with these techniques and implemented in such a way that they automatically adapt to updates in available data.

Quantification of convective heat and mass transfer of night ventilation to predict the energy performance. KU Leuven

Dirk Saelens
Building Physics Section
Nowadays, the application of active cooling in office buildings is hardly questioned in building practices. Also in temperate climates, active cooling is often assumed to be a necessary condition for a good thermal comfort. However, an optimal building design can go a long way towards reducing the cooling load. For example, night cooling can maintain thermal comfort during the day, by pre-cooling the building at night using cool exterior air at ...

Modeling, Optimal Control and HVAC Design of Large Buildings using Ground Source Heat Pump Systems KU Leuven

Lieve Helsen
Applied Mechanics and Energy Conversion Section

Since May 2010, the directive 2010/31/EU of the European Parliament compels its Member States to drastically decrease the energy use of buildings, to increase their energy efficiency and to increase the relative amount of renewable energy they use. One of the technologies recommended by the directive is the heat pump which efficiently uses electricity to extract thermal energy from a heat or cold source. In this work, buildings ...

DALY based assessment methods for iaq management Ghent University

Jelle Laverge
Department of Architecture and urban planning

The burden of disease due to exposure to air in the indoor environment is expected to change as more building owners will implement energy saving measures in response to the accelerating renovation wave. To investigate this potential change, a stochastic simulation based approach that models the burden of disease is necessary to capture the expected variations in the building stock, occupant behavior...
