Owner	Le Toit Vosgien (a social landlord)
Construction date	1959
Total floor area	2260 m²
Local climate	Temperate, rainy (Cfb) (Köppen Climate Classification)
Currently in use/inhabited	The building consists of 19 dwellings and is currently inhabited by a majority of seniors.

The surrounding terrain:

The building is on the side of a road and has parking at the rear with access from the side. It is surrounded by similar buildings and by individual houses. It has a small lawn to the front and trees and hedges around for privacy of inhabitants.

Key challenges

The challenges are to improve the complete insulation of the building to obtain a wall envelope U-value around 0.18 W/m2K, producing solar energy with second life panels and reduce energy consumption and emissions (50 kWh/m²/y).

Desired outcome

The desired outcomes are advances in Panobloc and improved performance including insulation, airtightness and ventilation, optimisation of lifting, laying and fixing methods for facades, rooftop solar energy production and potential replicability of this type of renovation.

The demo-site is a residential multi-family building with 19 dwellings in 1959. The surface of façades to be renovated is around 1,000 m² in PanoRen including 200 m² with PV modules (in facades and roof). The building is made of concrete walls with little or no insulation (the U-value of this construction is estimated at 1.5 W/m²/K). Energy consumption is related to space heating and DHW (200 kWh/m²/yr; energy class: D), as well as lighting and equipment. Each dwelling is equipped with an individual gas boiler and the total carbon footprint of the building is estimated at 74.3 tons of CO2 per year. This building is located at Saint-Roch district, a North-West area in the city of Saint-Dié-des-Vosges, France and the owner is a social landlord named Le Toit Vosgien.
