Module design

Calculation tree

The scope of the building module includes residential and service sector buildings.  It seeks to calculate the final energy demand for space heating and cooling, hot water, lighting and appliances.

An overview of the building module design can be found below, showing the calculation for one year, per country. It frames the scope of the model and shows its disaggregation into different calculation processes by main driver, e.g. floor area or population. On the far right, the calculation is broken down into the main drivers and the relevant specific energy factors

For a more detailed description of how the calculation tree is broken down into the main drivers and the relevant specific energy factors, please see the following document showing their detailed calculation (“Calculation Tree for the Building Sector”). The document can be downloaded here: EUCalc_Calculation Tree Building Sector_v2 (pdf – 750KB)


Inputs and Outputs Matrix

The energy inputs to the building sector and the energy outputs to other sectors have been summarised below and, in more detail, in the following table (xlsx – 13KB)


Data & Assumptions


The following document (WP2 Buildings_Levers_v01 – pdf 112KB) lists the drivers for energy demand in buildings, useful for a discussion on which are the most important drivers that should be included within the building module as a lever.

The list of levers will be further developed as the modelling activities for the building module proceed.

The selection of the levers to be included in the building module will be reviewed and validated by stakeholders in a co-creation process. The stakeholder workshop that is a major milestone within this co-creation process will be conducted in June 2018.



The Buildings work-package timeline is summarised in the figure below and highlights key milestones and expected outcomes.

1st version of the module

The draft version of the building module includes the calculations of the energy demand of a country based on (i) its total floor area, (ii) the share of single- and multi-family buildings, (iii) their respective energy need (useful energy demand). The combination of these first three datasets will already let us calculate the total energy need for the country. To get the delivered energy (final energy demand) the energy need for each building type is multiplied by the (iv) the share of the heating systems (energy mix), and (v) their efficiency.
