Development and application of test cases for comparing vertical ground heat exchanger models | 2007 | English
The main objective of this paper is to establish a set of test cases for analytical verifications and intermodel comparisons of ground heat exchanger (GHX) models used in building simulation programs. Several test cases are suggested.
There are several ways to attempt to model a building and its heat gains from external sources as well as internal ones in order to evaluate a proper operation and also audit retrofits actions.
Nowadays, building performance simulation (BPS) is still primarily used for code compliance checking in the Netherlands whilst it could provide the user already useful design information by e.g.
Towards a digital representation of physical phenomena to assess comfort in future environments | 2007 | English
This paper presents the concept and a test implementation of a digital representation of the physical world designed to assess comfort quality in future environments.
The paper presents the theory for a design tool to calculate drying of concrete, from green condition to flooring. The degree of hydration, the cement ratio of the concrete, the temperature and the moisture state are taken into account.
In the modern architectural design, large space open area is widely used, for example, atrium, airport, open office, etc.
Natural convection heat transfer within vertically eccentric domed skylights cavities | 2007 | English
Domed skylights are important architectural design elements to deliver daylight and solar heat into buildings and connect building’s occupants to outdoor.
Sensor-based information modeling for life cycle commissioning of residential buildings | 2007 | English
According to the National Institute of Building Science (2006), one of the main goals of building commissioning is to “maintain facility performance across its life cycle”.
While people need to know tomorrow’s weather to decide suitable activities and precautions, so do the “intelligent” building management systems.
Hygrothermal analysis on the use of internal thermal insulation systems in Portuguese residential buildings | 2007 | English
In Portugal, the external thermal insulation systems (ETIS) are nowadays a current technical solution in residential buildings, contrasting with the rarely used internal thermal insulation systems (ITIS). In this paper, a quantitative analysis on
On supporting design decisions in conceptual design addressing specification uncertainties using performance simulation | 2007 | English
Building performance simulation (BPS) is a powerful technique to predict the performance of a design proposal. It is extensively used towards the end of the design process to, for example, prove code compliance.
Performance assessment of residential cogeneration systems in Canada using a whole-building simulation approach | 2007 | English
A performace assessment study has been performed on the application of Stirling engine (SE) and Solid Oxide Fuel Cell (SOFC) residential cogeneration systems in single family detached houses in Canada. Detailed mathematical component models, calib
This paper explores effective means to opt for the optimum design solutions of commercial buildings through developing a Based-Simulation Design Support System (BSDSS).
Participants in building simulation supported projects are diverse (e.g. design teams, clients, project managers and simulation practitioners) and often geographically dispersed.
Simulation and analysis of the energy performance of an office building located in Rio de Janeiro – Brazil | 2007 | English
This paper aims to analyze an office building energy performance at Rio de Janeiro. Electrical power consumption profile of a building, resulting from a simulation using building energy-use simulation software, is obtained during a typical year an
Monitoring and evaluation of night-time ventilation and radiant cooling concepts applied to low energy office buildings | 2007 | English
This article presents a simulation study comparing the thermal interior comfort performance, the energy consumption and the efficiency of (i) nighttime ventilation concepts considering varying air change rates, (ii) three thermo-active building sy
There is an increasing demand for energy efficient and environment-friendly buildings with a high thermal comfort.
A comparative study of the IFC and gbXML informational infrastructures for data exchange in computational design support environments | 2007 | English
Significant progress has been made in the area of common data exchange in the building industry with the development of information technology. Currently, the Industry Foundation Class (IFC) and Green Building XML (gbXML) are two prevalent informa
Simulations as the way of bridging the gaps between desired and actual hygrothermal performance of buildings | 2007 | English
This paper deals with a common moisture problem in Swedish houses – the occurrence of high moisture levels in attics, and with a remedy proposed by building authorities – the ventilation of attic by outdoor air.
