Numerical simulation of buildings thermal behavior and human thermal comfort multi-node models | 2003 | English
In this work two numerical models are presented. The first one simulates the buildings thermal response and evaluates the internal air quality, while the second one simulates the human and clothing thermal systems and calculates the thermal comfor
Testing the energy simulation building model of Consoclim using bestest method and experimental data | 2003 | English
Consoclim is a building energy simulation software package which aims to simplify the input data. The building is modelled by only one capacity and five resistances.
The validation and development of turbulence models are still important issues related to Computa- tional Fluid Dynamics for ventilation purposes. The present work continues the work initiated by (Voigt, 2002).
The performances of air conditioning equipments, like heat pumps, chillers or air conditioners, derive not only from the operative thermal levels, but also from the building requirement trend which normally involves frequent reductions of t
This paper presents a simulation study employed for the optimization of the building envelope for a new university building located in Montreal (latitude 450N).
Experimental studies in building energy usage and environmental analysis are very time consuming and expensive, and require sophisticated sensors and instrumentation techniques.
Present international standard for thermal comfort such as ASHRAE Standard 55 and ISO 7730 were developed to serve as a guideline for moderate thermal environments e.g. mechanically air- conditioned spaces [CEN ISO 1995].
This article presents a one-dimensional model of spray vaporization that can be easily used in thermal performance simulations of buildings.
Procedures for calculation of NOx emissions reduction from implementation of the 2000 IECC/IRC conservation code in Texas | 2003 | English
Four areas in Texas have been designated by the United States Environmental Protection Agency (EPA) as non-attainment areas because ozone levels exceed the NAAQS1 maximum allowable limits.
Since buildings have a predominant impact on the global climate change and other environmental issues, it has become necessary to consider environmental performance in building design.
The lightswich wizard: reliable daylight simulations for initial design investigation | 2003 | English
A web-based, non-expert daylighting analysis tool has been developed to support daylighting-related design decisions in peripheral private offices during an early design stage.
Simulation and evaluation of markets for building cooling heating and power applications in the U.S. | 2003 | English
A two-level analysis was used to study the economic potential of implementing Building Cooling, Heating and Power (BCHP) technologies in the U.S.
The sky view factor indicates the relationship between the visible area of the sky and the area covered by urban structures.
Preliminary study on an estimation method for annual solar irradiance at varius geographial altutudes | 2003 | English
A preliminary investigation is made into the global variation in irradiance under the Clear, the Intermediate (partly cloudy) and the Overcast sky conditions (Nakamura et. al., 1986, 1987).
This paper describes modelling and simulation of a space with radiant cooling ceiling (CC). The computer model represents a test chamber, which is located in a laboratory of the Department of Environmental Engineering in Prague.
This paper draws the attention to the importance of a correct modelling of the inlet temperature of naturally and mechanically ventilated multiple-skin facades.
Embedded generation has been described as a “paradigm shift” in the way in which electricity is produced, with the focus of power production shifting away from large centralised generation plants to production of heat and power close
Shape factor calculation and visualization for the influence of the thermal enviroment on the human body | 2003 | English
The purpose of this paper is to explain the indoor thermal radiation environment of the human body in detail. Using a 3-D human body model, shape factor calculations between a human body and surroundings are executed.
A computer-model is used to simulate the evacuation of the occupants in a building.
