The implementation of a computational fluid dynamics algorithm within the ESP-r system | 1995 | English
Three computer programs have been developed for use in assessing solar heat gain through windows in buildings. SUNSPEC calculates the direct beam and diffuse sky solar spectral and broadband irradiances incident on an arbitrarily oriented plane, f
Visualize-ITTM is a visual data analysis tool kit. RLW Analytics has developed a number of specific data visualization tools for the study of the total load and end-use data produced by the DOE 2.1 building simulation package.
In this paper a new procedure of determining the thermal resistance and the thermal capacity of multilayer walls is described. Its feature is the simulation of the thermal behaviour of the wall with subsequent parameter identification.
Previous work has shown that for saturated air/water vapour mixtures, water vapour transfer in cavities can cause very large increases in net energy transfer due to its effect on natural convection.
Simultaneous modelling of heat and moisture transfer and air-conditioning system in buildings | 1995 | English
A simplified building heat and moisture transfer model has been developed and integrated with relevant air-conditioning system component models for simultaneous simulation of heat and moisture transfer at the building envelope, the indoor air-zone
This paper introduces a new approach towards the assessment of thermal building performance. As a specific aspect of overall building performance, thermal comfort performance is examined in detail. Two issues have been addressed.
This paper gives an overview and examples of varíous approaches to system simulation in buildings. Advantages and disadvantages of the different methods with respect to problems commonly encountered in building performance evaluation are described
The application, validation and further development of radiance : some UK activities | 1995 | English
RADIANCE has emerged as one of the most powerful programs for modelling the luminous environment within and around buildings.
The ability to integrate a range of disparate design tools has been an area of intense research throughout the world.
Comparison of cost and energy savings in an existing large building as predicted by three simulation programs | 1995 | English
Three energy analysis programs (BESA-Desian, PC-BLAST and MICRO-DOE2. 1 D) were used by threeresearchers to evaluate the energy and cost savings in a larae existing office building located in Montreal.
In computer simulation, accurate modelling of air conditioning equipment is important in the studies of dynamic plant performance, for instance in the selection process of a plant control scherne, in the investigation of plant energy consumptions,
Night ventilation for cooling purposes: part I- reference building and simulation model | 1995 | English
The aim of this study is to form the basis of a further analysis on night ventilation for cooling purposes in modern Swedish office buildings.
In order to improve upon previous calibration techniques, this paper presents new calibration methodsincluding a temperature bin analysis to improve hourly x-y scatter plots, a 24-hour weatherdaytype bin analysis to allow for the evaluation of hou
Description induced by modelisation methods in the case of building thermal simulation | 1995 | English
Two main modelisation techniques are the analytic and systemic methods. After a presentation of each method applied to building simulation, this paper emphases the benefit of systemic modelisation for multizone cases.
Implications of room air motion on control of thermal comfort in rooms with natural convection heat sources | 1995 | English
Electric and hydronic baseboard heating systems rely on natural-convection-driven air motion to distribute energy throughout a space to maintain thermal comfort. For electric baseboard heating systems employing an on/off control scherne, the room
An important aspect of the Texas LoanSTAR program has been the development of public domain software. These software are now available.
A new approach for computer-aided thermal analysis of buildings is presented. It is based on an electronic book "Building Thermal Analysis" which operates in a mathematical programmingenvironment (Mathcad).
Fault identification in air handling units using physical models and neural networks | 1995 | English
The main purpose of this paper is to develop fault detection modules for BEMS (Building Energy Management Systems), a software to aid building operators in detecting and diagnosing faults in HVAC systems.
The impact of central forced-air heating and cooling system modifications on the levels of selected pollutants in single-family houses was evaluated by simulating pollutant concentrations due to a variety of sources in eight houses with typical HV
