located in the south-eastern french city of chambéry, ‘HELIOS’ is home to the head offices of the national solar energy institute (INES) – an organization whose aim to to promote the development of solar energy. across a total area of 7,500 square meters, the building houses the institute’s laboratories, directors’ offices, various administrative services and the complex’s training department. jointly designed by the french architectural firms of michel rémon and frédéric nicolas, the project seeks to integrate functional and environmental features alongside architectural and urban aspects.
the scheme is designed as a continuous ring to minimize the amount of angles on the building’s façade. this compact horizontal and vertical design provides users with proximity between the various work areas, resulting in a friendly environment in which to conduct scientific research. at the heart of the plan, an atrium creates a noteworthy atmosphere in terms of light, spatiality, and ambiance. this indoor landscape is topped with a glass roof that brightly illuminates the entirety of the volume.
from an environmental perspective, the building is positioned in line with the region’s sun path, with a large rooftop wing tilted at a 30° angle. this elevated structure contains thermal sensors and photovoltaic panels designed to maximize the sun’s energy. each façade has been designed differently in response to particular external conditions. additionally, the solar protection of the bay windows (which offer natural light and warmth) reduces the need for active cooling and heating systems.
