Sustainable and innovative modernisation at the Pierre Charron
Sustainable and innovative modernisation at the Pierre Charron
In the heart of Paris, a historic building has been completely refurbished and equipped with a technical innovation: the first heating and cooling system to use TTAP technology. The flagship project for sustainable building technology is supported by integrated room and building automation from SAUTER France.
The 8th arrondissement of Paris is home to upmarket housing, luxury hotels and international companies. It is centred on the world-famous Avenue des Champs-Élysées with its elegant boutiques. It is also a hub of political life, being the location of the President’s official residence as well as embassies of seven G20 countries.
Since 2024, the district has also boasted an innovation for the building sector. A thoroughly renovated 18th-century property was revamped with a unique heating and cooling system. This is a world first: a non-public project regulating an entire building with the semiconductor-based TTAP technology* (Terminal Treatment of Air with Peltier) developed by Halton and Phononic.
The solution
The refurbishment was undertaken by Fayat Bâtiment, one of France’s largest construction companies and long-standing customer of SAUTER France. The classic façade of the Pierre Charron was largely preserved but the inside was completely transformed. Spacious, light-filled offices and commercial areas were created, as were new stairwells and lifts. The roofs were redesigned, with additions of roof gardens and glasshouse.
SAUTER France was tasked with providing room climate control and HVAC integration in the building management system. The SAUTER ecos system is responsible for room automation. This controls not only the ventilation system but also other installations such as a weather station. Besides indoor climate and lighting (via DALI interface), sun shading is regulated automatically too. Presence and brightness sensors optimally adapt the light to building use. Individual daily programmes maximise comfort while minimising energy consumption.
SAUTER Vision Center delivers a comprehensive real-time overview of building operation, including detailed analyses and energy monitoring. The service contract with SAUTER France also offers secure external access through remote management. Services for building automation, energy management, associated IT infrastructure and software applications are available round-the-clock.
The result
The building sector relies on technical innovations to reduce energy consumption and CO2 emissions. The heating and cooling system built upon TTAP technology significantly improves the building efficiency of the Pierre Charron.
SAUTER dovetails all the building and room automation functions with the higher-level energy building and management system. This guarantees optimised, flexible and energy-efficient operation of the property. The building has already been awarded BREAAM certification and the French HQE sustainability certificate – in both cases with the rating “Excellent”.
*TTAP Technology
A Peltier element is an electronic component that, when electricity flows through it, transports heat from one side to the other. This causes one side of the element to become colder while the other gets hotter. The technology can be found in electric cool boxes, for example.
Halton and Phononic are the first in the world to deploy this technology in a large HVAC system. It allows just partially conditioned air to cool and heat the entire building based on the settings made by users. The companies state that the new approach provides superior operational efficiency and costs, seamless installation and unparalleled convenience for users. Savings are achieved, for example, because no cooling water networks are needed, and the chillers are smaller. With fewer moving parts, less maintenance is required. Another advantage is that, unlike conventional compressor coolers, TTAP air cooling is largely silent. Furthermore, cooling is performed without any refrigerants which, in the event of a leak, are hazardous to both people and the environment.
