Modelling of hydrous and thermal transfers in tropicalclimates and buffering moisture with hygroscopic materials | 2005 | English
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 .
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.
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
Personalized ventilation (PV) has the ability to improve inhaled air quality and accommodate the individual thermal preference.
Numerous problems can occur for an investigator of larger datasets, e.g.
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.
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
Experimental and CFD research on the thermal performance of the air cooled slab system | 2005 | English
This paper presents an air cooled slab system (ACS) specially designed for use in multi-storey steel framed buildings.
Interfacing building performance simulation with control modeling using internet sockets | 2005 | English
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.
Modeling ground source heat pump systems in a buildingenergy simulation program (energyplus) | 2005 | English
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.
Parametric analysis of a solar dessicant cooling system using the simspark environment | 2005 | English
A desiccant cooling unit powered by 14.8 m2 of solar liquid collectors is implemented in a training room in Chambery in Eastern France.
Implementation of exergy –calculations in an existing software tool for energy-flow calculations in the early design stage | 2005 | English
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.
The thermal modelling of windows is often carried out at a high level of precision whilst irradiance anddaylight quantities are predicted using coarse approximations.
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
Measurement of the thermal environment in urban canyons and prediction by CFD simulation | 2005 | English
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
