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
Prediction of hygrothermal environment of buildings based upon combined simulation of heatand moisture transfer and airflow | 2005 | English
The hygrothermal environment of the Japanese traditional house constructed by wet process with clay wall and the recent house constructed with industrial building materials are estimated through the interrelated simulation of heat and moisture tra
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.
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
Tall buildings pose unique challenges for simulation software and modelers. Environmental factors such as air temperature and wind speed change with altitude.
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
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.
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.
A simplified optimization process (SOP) for determining set points is proposed and evaluated using the monitoring data and model of an existing VAV system.
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
Parametric analysis of a solar dessicant cooling system using the simspark environment | 2005 | English
A desiccant cooling unit powered by 14.8 m2 of solar liquid collectors is implemented in a training room in Chambery in Eastern France.
Implementation of exergy –calculations in an existing software tool for energy-flow calculations in the early design stage | 2005 | English
This paper focuses initially on the calculation of the flows of exergy corresponding to the energy demand of buildings for the following uses: heating and cooling in the air handling units, local (room level) heating and cooling, lighting, ventila
Modeling ground source heat pump systems in a buildingenergy simulation program (energyplus) | 2005 | English
Despite the low energy and lower maintenance benefits of ground-source heat pump systems, little work has been undertaken in detailed analysis and simulation of such systems.
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.
