Then, according to the features of the selected rooms, the strategies to reduce the energy consumptions were defined, taking into account the potential savings related to lighting, heating, ventilation, and air conditioning (HVAC) systems and other device loads (PC, printers, etc.).
The research approach adopted in the project started with the selection, as case studies, of representative test and reference rooms in modern and historical buildings chosen for having different requirements and constraints in term of sensing and control technologies. To make this possible, the proposed approach leverages upon the following main contributions: (a) to develop an integrated building automation and control system, (b) to implement a middleware for the energy-efficient buildings domain, (c) to provide a multi-dimensional building information modelling-based visualisation, and (d) to raise people’s awareness about energy efficiency. The approach does not require significant construction work as it is based on commercial-off-the-shelf devices and, where present, it exploits and integrates existing building management systems with new sensors and actuator networks. In this paper, we report a methodology, developed in the context of Smart Energy Efficient Middleware for Public Spaces European Project, aimed at exploiting ICT monitoring and control services to reduce energy usage and CO2 footprint in existing buildings. Analysis of results suggested that a number of necessary measures are required to ensure the reliability and accuracy of the simulation results. The same classrooms were modelled in Autodesk Ecotect using several modelling techniques and the internal temperatures were simulated using HTB2. Five primary classrooms built in a hot-dry climatic region were monitored.
This paper investigated the potential of using detailed thermal simulation software (HTB2) in conjunction with Autodesk Ecotect. Hence, the need to use more detailed thermal simulation tools during the final stage of a building design or research project.
Thermal performance analysis in Autodesk Ecotect is based on the Chartered Institution of Building Services Engineers (CIBSE) admittance method and thus inherits its limitations. It is very user-friendly software that could potentially integrate with the architectural design process. Autodesk Ecotect is a whole building simulation software that can predict the thermal, visual and acoustic performance of buildings.
