The present report describes two main upgrades that have been made to the JRC-EU-TIMES model during the year 2017:
• An improvement of the description of residential and non-residential buildings
• An update of data and a new representation for heating &cooling and heat distribution technologies
The model updates have been validated through tests with the JRC-EU-TIMES model and with stylised models allowing isolating the observed effect of the changed model input. The updates performed greatly improve the ability of the JRC-EU-TIMES model to perform studies options for the decarbonisation of the heating and cooling sector.
