The design index of building energy conservation and CAD program beep in Taiwan

The  purpose  of  this  research  is  to  develope  a simplified method to predict the relationship between the design of architecture envelope and the air- conditioning load in Taiwan. Four types of buildings including Office, Hospital, Hotel and Commercial Buildings with 4 regression formulas were established. The R-square value lies between 0.86 and    0.91    which    is    convincible.    The    norm „Regulations of Building Energy Conservation Design in Taiwan“ also referenced the results of this research.

The design analysis integration (DAI) initiative

The Design Analysis Integration (DAI)-Initiative aims to steer towards new solutions for design analysis integration. These solutions should be able to overcome the limitations of current interoperability approaches that assume the existence of generic and static interfaces in a ‘perfect world’ in which all information is structured and all mappings between design and analysis representations are computable. This paper reports on the first phase of the development, a first-generation prototype in ‘workbench’ style for managing a process driven design analysis dialogue.

Testing the energy simulation building model of Consoclim using bestest method and experimental data

Consoclim is a building energy simulation software package which aims to simplify the input data. The building is modelled by only one capacity and five resistances. The inputs related to the building are reduced to global U-values of the walls, solar factors of windows and two inertia parameters. This building model is assessed using BESTEST method. The results show that only few inputs are sufficient to characterise the building. A comparison with experimental data of building in operation shows a good agreement between the results on energy consumption of air conditioning system.

Technical and economical interest of sustainable refurbishment technologies in France, Italy and Filand

The aim of the European SSHORT (Sustainable Social Housing Refurbishment Technologies) project is to increase and promote rational and efficient use of energy in the retrofitting of social housing buildings. In this scope, one step was to evaluate with simulation studies the technical and economical interest of selected sustainable technologies on standard collective social housings in participating countries.

Spray vaporization for evaporative cooling of buildings

This  article  presents  a  one-dimensional  model  of spray vaporization that can be easily used in thermal performance simulations of buildings. A mathematical model of momentum, heat and mass transfer in the atomization zone was developed.Using a discrete particles model with separate flows and solving a non-homogeneous ordinary differential equations system, it is possible to verify the outflow, temperature and humidity of the treated air, at the end of the plume. These  algorithms could be coupled to  a  building simulation code.

 

Skyvision: a software tool to calculate the optical characteristics and daylighting performance of skylights

Skylights   can   offer   useful   benefits  in  reducing building energy consumption and improving building occupants satisfaction. Skylights may also offer interesting features which increase a  building’s market value by conveying an aesthetic look to buildings, admitting natural light indoors and connecting building occupants to the outside world. While skylight features are fully exploited, their benefits are still not fully understood and accounted for in currently available computer tools.

Sky view factors estimation using a 3D-GIS extension

The   sky   view   factor   indicates   the   relationship between the visible area of the sky and the area covered by urban structures. A method of sky view factors (SVF) estimation for urban analysis was developed and implemented in a Geographical Information System (GIS). In order to validate this tool, this paper presents a comparison of actual SVF with the results obtained by simulating the SVF in particular areas of a medium sized city with the developed tool.

Simulation support for the formulation of domestic sector upgrading strategies

This paper describes the application of a building simulation program to construct a decision-support tool for use by policy makers addressing the needs of the Scottish  domestic housing  sector.  The process of tool formulation is described and an example given of its use to identify best-value retrofit options while taking factors such as future climate change and improved standard  of  living into consideration. It is argued that the process of tool formation renders it applicable to the cumulative roll-out of upgrade measures in the long term, both within and outwith the UK.

Simulation support for internet-based energy services

The rapidly developing Internet broadband network offers new opportunities for deploying a range of energy, environment and health-related services for people in their homes and workplaces. Several of these services can be enabled or enhanced through the application of building simulation. This paper describes the infrastructure for e-services under test within a European research project and shows the potential for simulation support for these services.

 

Simulation of environmental impacts of commercial building systems

Hourly energy simulation  was used in combination with a life cycle assessment framework to model the environmental effects of energy consumption in buildings. The energy efficiencies and environmental impacts resulting from the construction and operation of alternative technnologies for providing space and water heating, cooling, and electrical power for equipment and lights in commercial buildings is evaluated.
