Assessing operational energy costs and energy performance of buildings using measured data

Management Summary

This document aims at describing Assessing operational energy costs and energy performance of buildings using measured data use case which is implemented as part of BIM-SPEED EU Horizon2020 project, under grant agreement No. 820553, https://www.bim-speed.eu/en. https://www.bim-speed.eu/en, using the ECOtool, developed by CARTIF https://www.cartif.es/en/ and adapted in task 5.2: Interoperability between multidisciplinary BIM tools and services to comply with the Key Performance Indicators (KPIs) defined in task 4.1: Baseline, KPI and Use Case definition and verification of the BIM-SPEED project. This use case allows to automate the calculation of a set of economic and environmental indicators related to the occupation and maintenance phases of the building renovation, to use it in different phases of the renovation process.


Use Case Definition


Aim and scope

The ‘ECOtool Service’ implemented as part of BIM-SPEED project is developed with the need for the objectives set by the BIM-SPEED Project. It helps in:

    • Reduced time and improved accuracy of results in renovation projects compared to traditional methods, as no user iteration is required in the calculation of the different indicators provided by the tool.
    • Reduce costs, as the user can quickly check the Payback Period for different investment costs depending on the selected renovation options.

Objectives

Automate the calculation of a set of economic and environmental indicators related to the occupation and maintenance phases of the building renovation. 

The comparison between the conventional practices to obtain the calculation of a set of economic and environmental indicators related to the occupation and maintenance phases of the building renovation process, with the use of the BIM-SPEED solution (ECOtool Service), as realized from implementation on demonstration sites, is shown in the image below:

Limitations

The tool needs different inputs from the users, if these values are not correct, the results obtained will be incorrect.

These documents do not claim to be complete. Nor are they to be understood in the sense of a recommendation or guideline that is generally valid from a legal point of view, but are intended to support the client and contractor in applying the BIM method. The use cases must be adapted to the specific project requirements. The examples given here do not claim to be complete. Information is based on practical experience and should therefore be regarded as best practice and not generally applicable.
