Awarded by the government “Investments for the future”, Grenoble is making sustainable building a priority, in particular in the Presqu’ile area. For this purpose, the city relies on new technologies and innovations. City-zen takes part in this ambitious project.

In 2010, the Grenoble Metropolis authority (la Métro) and its partners launched the Mur/Mur insulation campaign to implement objectives of its “Air-Energy-Climate plan” by giving technical and financial support to citizens that want to renovate their homes in a highly energy efficient way. A new campaign will run until 2020. Project overview with Sylvain Koch-Mathian, from la Métro and Arnaud Segon, from ALEC (Local Energy and Climate Agency of Grenoble metropolitan area).

How to give residents better access to their energy consumption data? How should they interpret  those, and above all, what will they do with it once they have better insight in their energy consumption? Engaging people in using the VivaCité tool, a collaborative platform for managing data for housing (electricity, heating, gas and water), is as challenging as setting up the tool itself. That’s why a second creativity workshop was organized to improve VivaCité and its interfaces on February 15th, 2017. Ideas and insights coming out of the workshop are valuable to anyone creating or pushing a multi user data platform.

“Teacher, that’s the day when we set up a multi-socket!” Giving individuals access to their energy usage, thanks to the VivaCité platform, is an ongoing initiative in Grenoble. As part of the 3rd edition of the successful "School Energy Challenge" lead by ALEC on the metropolitan area of Grenoble, one school benefits from a close monitoring and data sets to ‘play’ with. But what kind of data should be shown? On what scale? Which kind of data could be relevant for an educational purpose? Grenoble experiences this with the elementary school Anthoard.

To refurbish apartment complexes, 70% of the owners must consent with renovation activities. Collective decision-making is never easy. And if it involves money, well, it is even harder. To cater for that difficulty, the Local Energy and Climate Agency of Grenoble metropolitan area - ALEC, created a participatory workshop called “Refurbish my condominium : what a program!”.

70° is the temperature of the water coming in the new buildings which will circulate in the innovative lowpressure district heating network in Flaubert Ecodistrict, in Grenoble (and 40° coming out of the buildings). In the rest of the district heating network (high pressure), the water temperature is approx.135° (coming in) and 75° (coming out).  More info

16kWp is the renewable energy which will be produced by the pv plant with smart power management and storage features (4.5kWh storage), located on ALEC’s building roof. The aim is to maximize the direct use of the photovoltaic electricity produced. More info

3 social housing companies are involved in City-zen in Grenoble (Actis, Grenoble Habitat, Pluralis). That means 275 dwellings with an highly efficient refurbishment program, for a total of 26.207 sqm. More info
