Smart Building

Fenaco’s « Prisma » building in Puidoux has achieved heating energy savings of 50% while simultaneously substantially enhancing comfort for its users, including a 10% reduction in indoor temperatures in summer without air-conditioning. The improvements were achieved by analyzing two years of its weather control center’s solar radiation data and using the findings to effect natural cooling using a combination of Griesser’s automated solar shading solutions and air circulation via the building’s skylights.

The roof of Pavilion 6 in Paris’s Porte de Versailles exhibition park is home to «Nature Urbaine»Europe’s biggest urban roof farm, which sustainably produces fruit and vegetables over an area of some 12,000 square meters. A precise solar shading system managed by Griesser’s KNX technology ensures optimum light and heating conditions for the farm’s greenhouses to boost product yields. The project deftly blends green architecture, state-of-the-art technologies and an efficient circular system to deliver ecofriendly agriculture.

In 2020, ENS Cachan moved to the ultramodern Paris-Saclay campus, designed by Renzo Piano. This site, focused on energy efficiency and comfort, includes 60 electric actuators for the glass roof, 1,200 motorized vents for natural ventilation, and 3,200 facade blinds for precise control of light and climate. Five solar protection systems, managed by weather stations and KNX controls developed by Griesser, ensure optimal management. This technological synergy guarantees maximum performance and superior comfort.

The new main building, Anna-Seiler-Haus, is being constructed to the Minergie-P-Eco standard and is distinguished by advanced building automation that combines maximum energy efficiency with optimal patient comfort. The innovative KNX system by Griesser ensures intelligent and effective control of sun protection. Various sensors enable precise regulation and dynamic adjustments to external conditions. Thisintelligent networking creates a forward- looking environment for health and innovation.
