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
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.
Noriko Umemiya, Kiyoaki Iinuma, Toshiaki Nishioka and Ryoji Okura
Among  the  tools  which  serve  to  predict  heat  and mass transfer in a mechanically ventilated room, the CPD is increasingly used .
Frederic Kuznik, Gilles Rusaouen, Raluca Hohota and Nassim Safer
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
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

Personalized ventilation (PV) has the ability to improve inhaled air quality and accommodate the individual thermal preference.
Naiping Gao, Jianlei Niu
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.
Liang Zhou, Hongyu Huang, Amid Shakeri, Soheil Rastan, Ben Stach, Karen Pero, Edward Morofsky, Fariborz Haghighat
Increasingly the fire protection concerns at airports are being addressed using computational fluid dynamics and most of these studies have been based on the prescriptive recommendations on design of an airport terminal building given by appropria

This paper presents an air cooled slab system (ACS) specially designed for use in multi-storey steel framed buildings.
Agnieszka Isanska-Cwiek
This paper reports on progress of an ongoing research project, which aims to achieve better control modeling in building performance simulation by integrating distributed computer programs.
Azzedine Yahiaoui, Jan Hensen , Luc Soethout , Dolf van Paassen
Despite the low energy and lower maintenance benefits of ground-source heat pump systems, little work has been undertaken in detailed analysis and simulation of such systems.
Daniel E. Fisher and Simon J. Rees
A desiccant cooling unit powered by 14.8 m2 of solar liquid collectors is implemented in a training room in Chambery in Eastern France.
Etienne Wurtz, Chadi Maalouf, Laurent Mora, Francis Allard
This paper focuses initially on the calculation of the flows of exergy corresponding to the energy demand of buildings for the following uses: heating and cooling in the air handling units, local (room level) heating and cooling, lighting, ventila

Throughout its thirty year history, the transient energy simulation package TRNSYS has been under continual enhancement by an international group of developers and users.
David Bradley and Michaël Kummert
The thermal modelling of windows is often carried out at a high level of precision whilst irradiance anddaylight quantities are predicted using coarse approximations.
R. Ajmat Arch., J. Mardaljevic and V.I. Hanby
This paper gives an overview of recent developments and results of a new integrated heat, air and moisture (HAM) modeling toolkit in Matlab named HAMLab. The recent developments include integration of a whole building model with building systems a

We analyzed the thermal environment within Kyoto city using a numerical model that considers three elements: the unsteady-state heat conduction of building walls and ground surfaces, radiation heat exchange between walls and ground surfaces, and a

Active diffusing light pipes (such as hollow tubular lighting) are means of directing and diffusion light (daylight or electrical light) into interior spaces. The two principal objectives of this paper are : 1) to show the development of an advanc
