Computational Fluid Dynamic (CFD) has rapidly developed as an industrial design and evaluation tool for Building Services Engineering. Providing valuable information via mathematical predictions of fluid flow heat and mass transfer. The aim of the work is to illustrate the integration of CFD data into a truly interactive Virtual Reality (VR) environment to provide engineers with demonstrable design evaluation and visualisation facilities. To demonstrate the successful integration of CFD and VR an industrial case study of a conference room at Hoare Lea is presented.
This paper aims to outline the current state-of-the-art in integrated building simulation for performance prediction of heating, ventilating and air-conditioning (HV AC) systems. The ESP-r system is used as an example where integrated simulation is a core philosophy behind the development. The current state and future developments are illustrated with case studies. It is argued that for building simulation to penetrate the profession in the near future, there is a need for appropriate training and professional technology transfer initiatives.
Computer modelling is becoming an everyday tool for the building services engineer to ensure that a ventilation design will work early on in the development process. This paper describes this process in relation to Novartis' new office building in the UK. In this case, airflow modelling was used to fine-tune a conceptual idea for the atrium air conditioning. This influenced the solar shading incorporated into the architectural design and allowed engineers to optimise the volume of air used and the location of supply air terminals.
The possibility of using natural ventilation for commercial buildings is increasingly being considered. To assist natural ventilation in these buildings atriums are often suggested for the building's design as well as mechanical systems providing low air change rates. To ensure that natural ventilation will meet today's comfort expectations the proposed design needs to be evaluated using dynamic simulation software.
The intent of this paper is to present the design process which has created the new SELLIC Library for the University of Edinburgh. The design has evolved from the initial concepts completion in 1996 to a detailed design which is currently awaiting Client funding. The building's form has arisen by the integration of the :function, environmental strategy and the aesthetics.
This paper describes the development of a hybrid conditioning system that creates a comfortable indoor environment in a building. The operation of a variable-volume displacement conditioning system and a radiant cooled floor have been optimized to reduce the building load. Control strategies were developed that optimize energy consumption and contain moisture levels within specified limits. The development of conditioning-only occupied zones is shown and how the overall energy consumption is reduced. Its application in a large airport is described.
