This paper reports the final results of a research project, which aims to achieve better control modeling in building performance simulation by integrating distributed computer programs. The paper focus on developing Web-services based SOAP/XML to run-time couple control and building performance simulation. Data exchange via Webservices allows system components to be looselycoupled, rather than combined into an integrated building control systems.

This study has dealt with the energy and CO2 management at the new Kyushu University campus. The new campus named Ito Campus is located west of Fukuoka city, JAPAN, and opened on October 1st, 2005. In this paper, we estimated the CO2 emissions of new buildings at the Ito Campus by using simulated data and construction data, as the first step to develop an energy and environmental management system. In the evaluation, we compared the CO2 emission at the Ito Campus with the existing buildings at the old Hakozaki Campus.

In support of the movement towards the integration of modelling in the design process, a unified simulation-based compliance methodology for the energy performance of buildings was introduced in the UK Building and Approved Inspectors (Amendment) Regulations 2006 (England and Wales). As part of a larger project with the overall aim of presenting an analytical study of the process of introducing of this legislative approach to the UK construction industry, the paper reports on the status of the establishment of a simulation capability to support its use.

In Brazil, the energy crisis and the scarcity of financial resources to build new plants have increased the interest in saving energy. Buildings are responsible for using a vast amount of energy. To implement actions to save energy in old buildings, it is necessary to measure its energy efficiency. It is difficult to analyze the consumption of energy because of a great amount of variables. Even if there are some fixed variables, the external environment affects strongly the energy use.

The software bSol addresses to the professionals (engineers and architects) eager to optimize the parameters of a building project according to the local environment.

FACES is a simulation tool for selecting an appropriate heat source system in the early building design stage. Heat source systems have to be studied at an early design stage, because they are closely related to the floor plan. However, in an early design stage, most  of the problems are unsolved, so that there is insufficient data for system simulations. In order to enable detailed and accurate studies for various kinds of buildings and heat source systems,  FACES utilizes full-scale programs for heat load calculation and system simulations.

Paper is focused on description of Czech national methodology and tool for energy performance calculation according to EPBD (Energy performance building directive 91/2002). Energy performance calculation is expressed by total annual energy consumption, including heating, cooling, ventilation, auxiliary and other energy required for building operation. There is a simplified multizone model, loaded by typical day for each month in hourly time step. Climate data are synthetic data for 4 climate zones according to standards, used for building physics calculation.

This paper explores the developing process and resulting features of an ultra high performance tower designed by Skidmore, Owings and Merrill through a multidisciplinary approach to building simulation and analysis. The 309 meter tall office tower for a new development in the Pearl River Delta region of Southern China, is an exemplar of the marriage of technical sophistication with a graceful form, featuring integrated renewable energy strategies and an active double skin facade coupled with a low energy building conditioning system.

Models calculating the environmental benefits of renovation and retrofitting of buildings are generally based on energy calculations and don’t take into account the environmental penalty of demolishing and replacing parts of the building and its equipment.

The purpose of this study is to develop a thermal design tool for architectural designer by combining a heat balance simulation for urban surfaces, including buildings, the ground and greenery, with a 3D-CAD. This tool is constructed by improving the previous simulation model, which uses the Geographic Information System for the input data. The simulation algorithm is improved so as to predict the surface temperature distribution of urban blocks while taking into account the actual design of the outdoor space using the 3D-CAD system.
