Two-phase application of multi-objective genetic algorithms in green building design | 2005 | English
This paper presents the application of multi-objective genetic algorithms for green building design to minimize two conflicting criteria: the life-cycle cost and the life-cycle environmental impact. Environmental impact categories considered in th
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.
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.
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.
The thermal comfort, the indoor environment control, and the energy consumption in three types of operating rooms | 2005 | English
This research investigated the influence of three layouts of operating rooms on the indoor environment control, on thermal comfort and on energy consumption. It was used the EnergyPlus software. The parameters of the environment were described in
A simplified optimization process (SOP) for determining set points is proposed and evaluated using the monitoring data and model of an existing VAV system.
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
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 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.
The introduction of EU directives 2002/91/EC and 2003/87/EC both prompt a reduction in energy consumption from European buildings. Buildings account for 50% of European energy use.
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
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
Computational Fluid Dynamics (CFD) has evolved from an academic tool to an important commercial design tool over the past decades.
Burn Intensive Care Units (ICU) have among the most stringent design criteria for patient rooms in hospital design.
A mathematical model applied to building hygrothermal behavior analysis is described in this paper. We have used a lumped approach to model the room air temperature and humidity and a multilayer model in finite volumes for the building envelope.
