Accounting of heat in existing buildings: how to achieve the technical and economic analysis
THIM test is the free software of ENEA, in beta version, for designers who deal with heat metering in existing buildings
The installation of heat metering systems for buildings with centralized systems has been mandatory for almost a year.
ENEA has created and made available a simple software to facilitate designers and installers in the technical economic analysis of accounting systems to be installed in existing condominiums. It is called TIHM Test and is a software Viability Test Tool for Individual Heat Metering (TIHM) developed in collaboration with the DICEM Department of the University of Cassino with the aim of facilitating the work of designers and installers.
Through the simple spreadsheet of the THIM Test it is possible to carry out a technical economic analysis of the heat metering and heat cost allocators systems in the existing condominiums, as foreseen by the art. 9 c. 5 of Legislative Decree 102/2014 and Legislative Decree 141/2014.
Currently the downloadable software is still in beta, that is temporary, those who decide to download it will be able to test in advance the features and help developers to solve any problems or improve some details by sending comments via mail before the publication of the final version.
The software is developed on 7 spreadsheets that must be completed by the designer to obtain technical-economic analysis. Following the insertion of characteristic building data and specific information necessary for the assessment of technical feasibility, an outcome is obtained that indicates the type of accounting system that is optimal for the building according to UNI 10200 … and in this stage EQUOBOX becomes the protagonist!
