Evaluation of energy saving investments in buildings as a system of interdependent projects | 2005 | English
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.
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.
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.
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.
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
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.
Personalized ventilation (PV) has the ability to improve inhaled air quality and accommodate the individual thermal preference.
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.
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
