Developers of building simulation tools have been continuously improving their programs and adding new capabilities over the last thirty years. Time steps of less than an hour are now common and even necessary to properly simulate the complex interactions of building components and systems. For example, some control issues, such as daylighting, require much(More)
Saving energy in residential and commercial buildings is of great interest due to diminishing resources. Heating ventilation and air conditioning systems, and electric lighting are responsible for a significant share of energy usage, which makes it desirable to optimise their operations while maintaining user comfort. Such optimisation requires accurate(More)
Technological advances in real-time data collection, data transfer and ever-increasing computational power are bringing simulation assisted control and on-line fault detection and diagnosis closer to reality than was imagined when Building Energy Management Systems were introduced in the 1970s. This paper describes the development and testing of a prototype(More)
As introduced in a paper in Building Simulation '93, the training of users of simulation based thermal performance assessment tools is central to the efficacy of such tools within professional practice. A will-structured training facility can act as a 'virtual labo-ratory' for researchers and students. It is now possible to report on the results of the(More)
A wide range of events in buildings occur at sub-hourly frequencies. Notable examples include daylight-sensing control and manual adjustment of blinds and lights in response to sub-hourly illuminance variations. Such short-term changes can produce notable shifts in instantaneous solar and equipment loads, in turn affecting electrical energy demand. Although(More)
There are two main issues to be resolved in order that design tools can be used in cooperative mode, each communicating with the other. Firstly, there is a need to put in place a consistent product model of a building and its systems from which disparate design tools can obtain their inputs and return their outputs. Secondly, there is the requirement to(More)

High quality thermometry is needed in hyperthermia to (1) ensure safe delivery of adequate therapy and (2) provide the quantitative information needed to develop prognostic parameters which will aid research into planning and dosimetry. Currently, only invasive thermometry which is subject to several sources of artifact is available to address these(More)
Progressive design practices are increasingly cognisant of the potential of building energy simulation to assist the delivery of energy efficient, sustainable buildings. However, the success of any building performance assessment hinges on the capabilities of the tool; the collective competences of the team formed to apply it; and, crucially, the existence(More)
