Buried pipe systems with sensible and latent heat exchange :validation of numerical simulation against analytical solution and long-term monitoring | 2005 | English
This paper deals with the use of computer simulations both for design support of a new building including its heating, ventilation and air-conditioning (HVAC) systems and for optimization of the HVAC control strategy during operation of the comple
This paper deals with the dynamical modelling of a solar evacuated tube collector under variable weather conditions. After describing the mathematical model, the paper presents elements of validation.
There is a strong demand for accurate moisture modelling since moisture poses a risk for both the constructions and the indoor climate. Thus, in this investigation there is special focus on moisture modelling.
Design standard of energy conservation for building hvac 1system – a simplified method of chiller capacity estimation 2based on building envelope energy conservation index in 3taiwan | 2005 | English
The research developed maximum chiller cooling capacity predicting equations with building shape factor and the ENVLOAD index which is now the building envelope energy conservation design control factor in Taiwan.
To have a proper energy management in buildings, it is necessary to evaluate its HVAC system. To properly compare operating strategies and solve possible problems, one needs to reproduce the building and its HVAC system behavior under real life co
This paper presents first steps of a methodology for calibration of building simulation models through definition of the parameters that most affect the main electric end-uses of a building.
This paper presents the results of a comparison between measurements of a co-heating test in a passive house and the simulated response of the building to the same outdoor conditions calculated with the building simulation program Trnsys. Special
An efficient urban energy system could be a highly diverse and well-integrated structure of buildings and systems.
This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force.
This paper describes the design and simulation of a hybrid ventilation system for a recently constructed circus building in Montreal. The HVAC system draws fresh air through two underground ducts which are used for preheating or precooling.
Energy and financial performance of micro-chp in connection with high-performance buildings | 2005 | English
This paper deals with the issue of using micro- Combined Heating and Power plants (mCHP) in high-performance houses in terms of energy conservation and cost savings.
Building effectiveness communication ratios for improved building life cycle management | 2005 | English
Many existing building energy performance assessment frameworks, quantifying and categorising buildings post occupancy, offer limited feedback on design decisions.
Comparison of candidate materials for seasonal storage of solar heat through dynamic simulation of building and renewable energy system | 2005 | English
In a survey recently conducted by ECN and the University of Utrecht in The Netherlands [Visscher, Oonk et al, 2004]), several potential thermo chemical materials (TCM's) for seasonal storage of solar heat were determined.
Development of archetypes of building characteristc slibraries for simplified energy use evaluation of houses | 2005 | English
For a quick and reliable energy evaluation of houses, one needs simple energy analysis software.
Past research of predictive optimal control of active and passive building thermal storage inventory has confirmed the importance of accuracy in the employed building model.
Daylighting Simulation is a complex task, involving many parameters, but an important step to design buildings, especially when the main purpose is more comfort and energy conservation.
It is well recognised that validation of dynamic building simulation programs is a long-term complex task.
Assessing the total energy impact of occupant behavioural response to manual and automated lighting systems | 2005 | English
Behavioural models derived from on-going field studies can provide the basis for predicting personal action taken to adjust lighting levels or remedy direct glare in response to physical conditions. SHOCC, a sub-hourly occupancy-based control mode
Previous simulations predict the possibility of reducing cooling demands in office buildings in hot arid areas if a selective double skin facade is used. The reductions on cooling loads in rooms range between 19%-40% depending on the glazing therm
