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

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.
Alain Bastide, Franck Lucas, Harry Boyer
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

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.
Cheol-Soo Park, Godfried Augenbroe, Mate Thitisawat
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.
Mohit Mehta
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
Christoph van Treeck and Ernst Rank
The use of Matlab, a tool for mathematical programming, is actually increasing in a large number of fields.
P. Riederer
Multizone network models employ several assumptions, such as uniform pressure and quiescent air inside the zone, which may cause inaccurate results in flow calculations.
Liangzhu (Leon) Wang, Qingyan (Yan) Chen
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.

Among  the  tools  which  serve  to  predict  heat  and mass transfer in a mechanically ventilated room, the CPD is increasingly used .

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.
Franck Lucas, Frederic Miranville, Alain Bastide
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.
Valentin Trillat-Berdal, Bernard Souyri, Gilbert Achard
Numerous problems can occur for an investigator of larger datasets, e.g.
Thomas Olofsson, Jan-Ulric Sjögren and Staffan Andersson
Computational Fluid Dynamics (CFD) simulation technique was used to study the effect of air distribution and supply parameters on ventilation performance and comfort of occupants in a government office building in Ottawa, Canada.

Personalized ventilation (PV) has the ability to improve inhaled air quality and accommodate the individual thermal preference.
Naiping Gao, Jianlei Niu
This paper presents an air cooled slab system (ACS) specially designed for use in multi-storey steel framed buildings.
