The residential sector is responsible for 40% of greenhouse gas emissions due to the old and poor characteristics of buildings. That makes urgent and necessary to develop a strategy to deep retrofit the building stock. EMREE is a long-term urban planning virtual instrument for the energetic housing renovation. It uses the architectural and energetic characterization of the buildings to calculate investment and return costs of renovating them with sustainability criteria acting as a road map to achieve the 2050‘s EU decarbonization objectives.

The instrument is accessible to users through an online visor and is addressed to municipal agents, responsible for activating the renovation process, and inhabitants who will be able to check the state of their building and to quantify investment necessary to renovate it.

EMREE’s online visor provides 3 types of information:

1. Georeferenced and quantitative diagnosis of the buildings in terms of construction features and energy demand in order to divide the building stock into segments and to calculate domestic energy consumption, making a special effort to map energetic vulnerable buildings to allow developing fuel poverty policies.

2. 48 scenarios action plan combining different variables that determine energetic renovation economic viability and its plan in time. For each scenario different values are calculated: energy consume reduction, C02 emissions reductions, number of buildings refurbished, investment (public and private) and return times.

3. Action guide for building managers which should allow considering specific situations that may occur and how to tackle renovation in each case.

The information that EMREE provides is developed through deep analysis of land registry with GIS and data analysis with a self-developed python application. Methodology used is provided in two action plans that Ciclica collaborated to develop: GTR reports and Long-term strategy for energy renovation in the building sector in Spain. Two strategies to transform all the buildings built before 2001 into low energy demand and low emission buildings bringing benefits not only to their occupants but also to the country creating new jobs and opportunities

The tool has been entirely funded by town halls and metropolitan corporations.
