Modeling of the double-skin facades for building energysimulations: radiative and convective heat transfer | 2005 | English
Exergoeconomic modeling of geothermal district heating systems for building applications | 2005 | English
Geothermal district heating systems (GDHSs) are modeled by examining the relations between thermodynamic losses and capital costs for the devices comprising the GDHSs, and some possible generalizations are proposed relating thermodynamic losses an
Stand-alone software for predicting contaminant transport and behaviour is well developed, but to be more effective, it needs to be integrated within whole building simulation.
This paper deals with the development and the evaluation of hybrid ventilation control strategies, using both natural and mechanical modes, in residential buildings using a graphical simulation tool. The description of a library of airflow compone
Impact of the atmospheric boundary layer profile on the ventilation of a cubic building with two large oppositeopenings | 2005 | English
The aim of this paper is to show the influence of the atmospheric boundary layer profile on the distribution of velocity in a building having two large openings.
The paper describes a research project which addresses the problem of supervisory control of systems which include a range of heat sources combined with active and passive thermal storage. The work is based around a prototype building which has a
This paper describes how the energy performance of single storey multiple-skin facades can be optimized by changing the settings of the facades and HVAC system. The energy performance is analyzed with a yearly whole building energy analysis under
Evaluation of energy saving investments in buildings as a system of interdependent projects | 2005 | English
During a design stage building designers have to do many decisions that will influence an energy consumption in a designed building. Investments to a building structure and HVAC system are a basis for a low consumption of an energy.
This paper represents the next step in the development of occupant responsive optimal control for double-skin systems that was presented at the IBPSA 2003 conference.
This paper is part of a larger research to ‘theoretically’ review the application of natural ventilation to commercial buildings, the potential advantages these systems offer, and some pitfalls that must be considered.
Geometrical and topological issues for coupling dimensionally reduced multizone models with high-resolution CFD techniques | 2005 | English
In this paper we emphasize a technique based on graph theory that allows for deriving both a dimensionally reduced object model required for setting up a thermal multizone model and a geometrical model for defining a single or multiple CFD domains
The use of Matlab, a tool for mathematical programming, is actually increasing in a large number of fields.
On solution characteristics of coupling of multizone and CFD programs in building air distribution simulation | 2005 | English
Multizone network models employ several assumptions, such as uniform pressure and quiescent air inside the zone, which may cause inaccurate results in flow calculations.
Horizontal diffuse illuminance and direct illuminance were estimated by measured sky luminance distribution to investigate the consistency among global, diffuse and direct illuminance for a long-term IDMP data in Kyoto, Japan.
Inlet Boundary conditions for simulating flows in rooms impact of the ventilation system | 2005 | English
Among the tools which serve to predict heat and mass transfer in a mechanically ventilated room, the CPD is increasingly used .
Modelling of hydrous and thermal transfers in tropicalclimates and buffering moisture with hygroscopic materials | 2005 | English
Controlling humidity to prevent moisture and condensation phenomena is a growing problem for building designers nowadays. Ventilation and air conditioning are common solutions to avoid mold and condensation.
From floor plan drafting to building simulation - an efficient software supported process | 2005 | English
The paper describes a process that efficiently supports the early building design stage with prototype tools to capture topological floor plan sketches, calculate geometries, explore design alternatives, and generate data for performance simulatio
It is beneficial for the safe and optimal operation of system and energy conservation to find out and eliminate the faults existing in HVAC systems in time. For a large-scale and complex HVAC system, an automatic fault detection and diagnosis syst
This study is focused on the ground heat pump (GHP) used in heating single-family houses. These systems generate a ground heat depletion which decreases its performances after several years of operation.
Numerous problems can occur for an investigator of larger datasets, e.g.
