Experimental Solar Building - Lausanne

Experimental Solar Building in Lausanne

The experimental solar building LESO of the ” Ecole Polytechnique Fédérale de Lausanne ” built in 1982 constitutes one of the main research tools of the Solar Energy and Building Physics Laboratory.

EPFL Development design:
LESO Laboratory LESO Laboratory LESO Laboratory

It has been designed with a facade composed of 9 interchangeable modules. The objective was to test the energy performance of different types of facade composition. The laboratory is fully instrumentalised and managed by many computer resources, ensuring a perfect modeling and development of systems analysis

The building has a very low specific energy consumption (energy performance indicator of 200 MJ/m2 year), achieved thanks to the efficient thermal insulation of the envelope (U = 0.4 W/m2 K), the building’s efficient passive solar energy use (main glazed surfaces south exposed) as well as its thermal inertia (inner walls made of concrete and cement blocks).

About twenty passive solar and hybrid systems have been tested on this buiding. The roof integration of a 3 kW-peak photovoltaic solar power system in 1990 has allowed to show the affinity between this decentralised kind of power generation and the building.

The south facade, which was redesigned in 2001, with a reference to vernacular architecture of the Schwitz (CH) canton, shows an even better energy performance (integrated daylighting system) and its low environmental impact (90% local materials with a low grey energy content and greenhouse gas emission neutral).
