A finite differences numerical model for buried pipe systems is presented, accounting for sensible as well as for latent heat exchanges, so as for fully three dimensional heat diffusion in soil and flexible border conditions.
Pierre Hollmuller and Bernard Lachal
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.
Lone Hedegaard Mortensen, Monika Woloszyn, Raluca Hohota and Gilles Rusaouën
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.
Kuo-Tsang Huang, Hsien-Te Lin
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.
Fernando Simon Westphal and Roberto Lamberts
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.
Y. Yamaguchi , J. L. M. Hensen , Y. Shimoda , T. Asai , and M. Mizuno
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.
Malcolm Cook, Yingchun Ji and Gary Hunt
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.
A.K. Athienitis , M. Roy , and M. Zhao
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.
Benoit Sicre , Andreas Bühring, Bernd Platzer
Many existing building energy performance assessment frameworks, quantifying and categorising buildings post occupancy, offer limited feedback on design decisions.
Morrissey Elmer, O'Donnell James, McCarthy John, Keane Marcus
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.
K. Visscher, J.B.J. Veldhuis
For a quick and reliable energy evaluation of houses, one needs simple energy analysis software.
Anil Parekh
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.
Simeng Liu, Gregor P. Henze
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.
Dimitrios Evangelos Christakou, Claudia Naves David Amorim
It is well recognised that validation of dynamic building simulation programs is a long-term complex task.
Strachan P A, Kokogiannakis G and Macdonald I A
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
