The work undertaken by the Welsh School of Architecture for the AUDITAC project builds on a major AC Energy Use in Offices Field Monitoring Study previously undertaken by the WSA.

Within the AUDITAC project, the Welsh School of Architecture are responsible for Work Package 7 – Generation and Structuring of Customer Advising Methods.

The Welsh School of Architecture worked closely with the University of Porto and the University of Liege to produce the information required to provide the basis for these Methods, as well as to produce the data needed for each of the methods .


The main work undertaken by the Welsh School of Architecture during the project is the production and validation of information about the effect on AC system energy consumption of the most common building and AC system operation, design and refurbishment options.  This forms the core of Work Package 7.

The modelling and assessment of previous monitoring work within real buildings in the UK forms the Welsh School of Architecture’s support to Work Package 6.

These two work elements assist the project Databases in WP6 and WP7 to be populated as fully as possible with information on actions and associated savings that may be obtained in the EC region.

The work relied heavily on the following elements:

·  Measured information from the previous monitoring project.

·  The production of an accurate interface to the modelling tools ESP-r, EnergyPlus and ECOTECT

·  The production of a robust modelling methodology to allow the inevitable modelling inaccuracies to be allowed for in the estimation of the energy impacts of various parameters.

The outputs from the WSA’s work, in conjunction with information from the other Partners in the project, are used to produce a coherent package of information from the project as a whole.

The main output from the Welsh School of Architecture for this project, other than the Case Studies and Papers, is the Customer Advising Tool (CAT). This online tool is intended to allow Inspectors, Auditors and Building Owners/Operators to assess where the main opportunities might lie for improving the energy efficiency of the A/C systems in their buildings, through amendments to the building operation and components.

The tool provides the interface to the main results and findings from the detailed modelling and monitoring undertaken by the Welsh School of Architecture and INEGI in Porto.
