Simulation of cleaning is a new area in building simulations. To make rational cleaning is it important to know how difficult it is to clean rooms. I define a Cleaning Index (CI) as the cleaning area divided by the floor area.
A model for the design of urban grids and fabric with solar rights consideration taken into account is presented.
Project REED (Residential Energy Efficiency Design) is a Web-based building performance simulation tool developed under contract to one of the nations largest utilities, to help their 4.5 million ratepayers make en- ergy efficient design decisions
Study on adaptive mesh generation method in CFD calculation with conjugate heat transfer model | 1999 | English
In order to make proper radiative meshes with considering thermal distribution on solid surfaces, we inves- tigated the adaptive mesh generation method and per- formed parametric survey for a threshold which con- trols subdivision of mesh.
Numerical analysis of air temperature increases in urban area using the building-urban-soil simultaneous simulation model | 1999 | English
The authors propose a predicting methodology combined with simultaneous solution for Building- Urban-Soil system to analyze the heat island phenomenon quantitatively in this paper. Using this model, numerical simulation is performed in order
Simulation of visual context in architecture, the environment that surrounds both building and observer, is an essential but problematic feature of realistic imagery.
An integrated simulation system for the building services design and facilities management purposes is being developed by Olof Granlund Oy.
Modeling and calibration of lateral heat loss rate in measuring the R value of partly heated wall | 1999 | English
An experimental apparatus (in-situ thermal test unit) and an analysis method have been developed for evaluating the thermal resistance of the building envelope on site.
A major goal in computer-aided design research has been the development of integrated design for convenient generation and evaluation of evolving designs.
Based on K- two equation turbulence model, we used PHOENICS 1.4 and numerically simulated air distribution and contamination field under different conditions in a vector- flow clean room.
Numerical prediction of hot water flow and temperature distribution in thermal storage tank | 1999 | English
In order to evaluate energy efficiency of solar hot water systems, a calculation method was developed in this paper that models the unsteady flow and temperature distribution in heat storage tank utilizing Computational Fluid Dynamics (CFD). Compa
Selection and control of HVAC systems for optimal life-cycle efficiency using simulation techniques | 1999 | English
Design of air conditioning systems for efficient and effective part-load operation poses a considerable challenge, but one which is frequently not appreciated by the designer tied to traditional design practices.
M2M&Roofsol: a tool for evaluating the cooling performance of passive roof components using teh model synthesis method | 1999 | English
This communication presents a tool, m2m&Roofsol, which has been developed in the framework of a European project, ROOFSOL, dedicated to the study of passive cooling by roof components.
This paper explains the development of a dedicated configuration tool for the HVACSIM+ simulation environment. This computer-based tool eases configuration by exploiting a visual metaphor of a simulation subject.
Enhancing and extending the capabilities of the building heat balance simulation technique for use in EnergyPlus | 1999 | English
With the advent of the computing age, heat balance based techniques for simulating thermal loads in buildings became a reality for architects and engineers.
Many recent, moisture-originated failures in low-rise residential and high-rise residential/commercial buildings have put a significant pressure to change construction codes in North America and Europe.
Dynamic optimization technique for control of HVAC system utilizing building thermal storage | 1999 | English
This paper proposes a dynamic optimization technique for building heating and cooling systems. The proposed algorithm returns trajectories for space temperature setpoints throughout a specified period that will minimize objective functions such as
