Development of an air-based open loop building-integrated photovoltaic/thermal system model | 2009 | English
Photovoltaic systems can reduce the CO2 emissions associated with the consumption of electricity in dwellings.
This paper addresses the potential of the simulation assisted operation of devices for natural ventilation. Toward this end, a control scheme was conceived as follows: at specific points in time, the control system applies simulation to predict ho
Key factors - methodology for enhancement and support of building energy performance | 2009 | English
This paper presents the Key Factors methodology that supports energy managers in determining the optimal building operation strategy in relation to both energy consumption and thermal comfort.
The present work focuses on investigating ways to enhance the energetic performance of buildings i.e. on proposing control strategies for managing energy in buildings.
In a simulation-powered building systems control approach, presently available control options are virtually projected onto a future time step via numeric simulation.
Dynamic test method for the determination of the global seasonal performance factor of heat pumps used for heating, cooling and domestic hot water preparation | 2009 | English
The necessity of innovation on the field of renewable energy systems imposes on the industry to develop faster and faster new products or product assemblies while managing perfectly the quality of the products. In order to accelerate this process,
ESP-r is a powerful tool for simulating building environments and their various mechanical and electrical systems. It has potential for investigating and optimising the thermal performance of enclosed areas of ships and other ocean vessels.
Computer simulation for better design and operation of large office building air-conditioning | 2009 | English
The paper deals with the use of computer simulations both for the design support of a new buildings and HVAC system development and for the optimisation of the system control strategy in the building.
Comparison of different approaches for the simulation of boilers using oil, gas, pellets or wood chips | 2009 | English
A detailed model for the simulation of boilers using oil, gas, pellets or wood chips has been developed and compared with measurements. Approaches of different complexity for the simulation of steady state flue gas losses were tested.
An implementation of co-simulation for performance prediction of innovative integrated HVAC systems in buildings | 2009 | English
Integrated performance simulation of buildings and heating, ventilation and air-conditioning (HVAC) systems can help reducing energy consumption and increasing level of occupant comfort.
For engineering applications one-dimensional models of urban ponds are suitable in order to assess the energy potential for heating and cooling of buildings.
Approximate analytical solution for the heat transfer in packed beds for solar thermal storage in building simulators | 2009 | English
Schumann solution for the heating (cooling) of onedimensional packed beds by the passage of a hot (cool) fluid is extended by the incorporation of a small solid thermal conductivity by means of using perturbation methods based on the Laplace tran
A fundamental approach to cooling load calculations for UFADS and stratified spaces | 2009 | English
(UFADS) or a stratified atria involve special thermal exchange processes that require special load calculation procedures.
ETFE (ethylene tetrafluoroethylene) is a lightweight material increasingly used in building applications. It has gained popularity mainly due to its daylight transmittance and the potential for energy savings.
Development and validation of a versatile method for the calculation of heat transfer in water-based radiant systems | 2009 | English
The description of the thermal behaviour of radiant systems is complex due to the 3D heat transfer and the relevant thermal inertia characterising the active surface.
Impact of grey water heat recovery on the electrical demand of domestic hot water heaters | 2009 | English
Grey water heat exchangers (GWHE) are used to recuperate part of the energy contained in grey waters.
The purpose of this study is to quantify the impact of insulation of various parts of building envelopes on building energy consumption.
Computer modelling at the urban scale is an increasingly vibrant area of research activity which aims to support designers to optimise the performance of new and existing urban developments.
Analyzing the economic feasibility of permutations of energy saving measures with batch simulations and Pareto optimization | 2009 | English
Two years after the implementation of the Flemish energy performance regulation, the Flemish government has to consider the opportunities for strengthening the minimal energy performance requirements.
