Prediction of hygrothermal environment of buildings based upon combined simulation of heatand moisture transfer and airflow | 2005 | English
This paper critically examines the use of Analytic Target Cascading as a multi-level, hierarchical design optimization model for formulating simulation-based design tasks in architecture.
This paper describes a new data set appropriate for empirical validation of whole-building energy simulation software.
This paper presents two DOE-2 functions to expand the modeling capability of DOE-2.1E, a popular calculation engine for building energy simulations. The first function models sensible and total heat recovery between outside air and exhaust air, wi
Tall buildings pose unique challenges for simulation software and modelers. Environmental factors such as air temperature and wind speed change with altitude.
The robustness of genetic algorithms in solving unconstrained building optimization problems | 2005 | English
This paper investigates the robustness of a Genetic Algorithm (GA) search method in solving an unconstrained building optimization problem, when the number of building simulations used by the optimization is restricted.
Position uncertainty in space scene reconstruction for simulation-based lighting control | 2005 | English
Dynamic, three-dimensional models of existing facilities that are updated automatically based on data provided by advanced sensing technologies appear increasingly feasible.
Heating Canadian homes is an energy intensive endeavour. Factors such as the northerly climate and dispersed population cannot be avoided but inefficiencies with heating system design can.
Static and dynamic daylight control systems:shading devices and electrochromic windows | 2005 | English
This paper analyses the office demand connected to the use of different dynamic window and lighting control systems with the aim to optimize their usage aspects and characteristics from both visual and energy efficiency viewpoints.
Toward a unified information space for the specification of building performance simulation results | 2005 | English
We present a framework for the specification of building performance simulation output results. Toward this end, we describe a simulation output space, whose primary dimensions include scalar and vector attributes, spatial destination, temporal de
A simplified optimization process (SOP) for determining set points is proposed and evaluated using the monitoring data and model of an existing VAV system.
The numerical modelling of the diffusive-convective watervapour transport through the building constructions | 2005 | English
The following paper is focused on the effects of the combined water vapour transport caused by diffusion and convection.
An 'active façade' responds to (and anticipates on) changing indoor and outdoor conditions.
Simulation of the effect of an energy recovery ventilator on indoor thermal conditions and system performance | 2005 | English
In recent years, indoor humidity levels are gaining greater attention in building design and operation, due to the increasing concern over moisture-related problems, such as mold growth, indoor air quality and discomfort of the occupants.
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
Throughout its thirty year history, the transient energy simulation package TRNSYS has been under continual enhancement by an international group of developers and users.
Hygrothermal simulation of drying performance of typical north american building envelope | 2005 | English
Hygrothermal modeling of building envelope has received much attention and development in recent years; to increase its flexibility and accessibility is a consequential task.
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
