The 'energy performance rating of dwellings in Malta' : an evaluation in comparison with equivalent European tools

Abstract

This dissertation comprises the assessment of the national calculation tool 'Energy Performance Rating of Dwellings in Malta'. (EPRDM). The study was set out to explore and assess the strengths and weaknesses of the tool. The main aim was to highlight what changes and improvements could be done, not only to the software package itself, but also to the assessing system as a whole, to address its weaknesses and improve over its strengths. This was done by a thorough analysis of the software tool on its own merits, and then comparing the EPRDM tool to a selection of EPBD tools, namely DEAP, SAP, ISBEM-CY and DOCET, and by conducting a survey amongst locally registered EPB assessors. The main strengths and weaknesses of the EPRDM were highlighted, and various measurements and improvements of the EPRDM tool were directly related to such findings; measurements which could potentially improve the EPRM tool. Furthermore, specific features and components of the chosen EPBD tools that could potentially be implemented in the EPRDM were highlighted. The main conclusions and recommendations for the improvements of the EPRDM tools related to the (i) EPRDM Interface and Reporting of Results, (ii) Additional Features, and (iii) Improvements to the EPRDM tool. In conclusion, for a Member State, such as Malta, to derive the maximum benefit from energy efficiency improvements, it is fundamental that the only recognised methodology for the energy certification of residential property, EPRDM, is credible and highly Accurate, so that the real benefit of an EPC can be appreciated, recognised, and taken more seriously by the general public.
