ALTEREA received Chengdu TV1 in France


Chengdu TV1, bolivar, rénovation, chaufferie bois, travaux, efficacité énergétiqueAn economic and commercial cooperation agreement on eco-neighbourhood was signed in November 2010
between the French Ministry of Economy, Industry and Employment and the Chinese Ministry of Commerce. Three major cities have been designated: Chengdu, Chongqing and Shenyang.

Chengdu, the bubbling capital of Sichuan, keeps growing and wants to see further. A mission of Franco-Chinese experts began in this city of 14 million of inhabitants. The objective: associate the “Made in France” know-how to develop a Franco-Chinese neighbourhood, with an area of 22 km2, in Long Quan Yi, east of the city. Like many Chinese cities, confronted by a rapid development, Chengdu is growing up and dreams about a French sustainable city/ sustainable city “à la française”.

An agreement signed on March 26th 2014 extended this partnership to a cooperation about environment and energy efficiency. The cooperation’s field of this administrative agreement concerns particularly the common realization of “the Chengdu’s Franco-Chinese eco-neighbourhood”.

This is the context in which a Chengdu TV1’s team created a report about two ALTEREA Parisian’s construction sites.

Alban Lapierre received journalists in order to share the feedback of these two Parisian sites:

  • A model rehabilitation for our client Paris Habitat in the context of the Paris’ Climate Plan
  • A wood heating in Verrières-le-Buisson: heat network which feeds for public equipment of the city

Bolivar-Chaufourniers-Moreau housing complex

The property complex Bolivar-Chaufourniers-Moreau is composed of 473 housing in the 19th district of Paris. The rehabilitation works will reduce energy consumption more than 60%.

The works, costing 30 M€, will enable:

  • To restore the group’s urban coherence and solve insecurity’s problems
  • To rethink outside developments and the public, residential and private spaces
  • To apply technical solutions to achieve the Paris’ Climate Plan’s objectives and reduce tenants’ expenses improving their comfort

Wood energy heat network in Verrières le Buisson (91)

Jean-Louis Delort, deputy mayor, was also present to share his feedback.

Indeed, for several years, the city of Verrières has set the objective to exploit local energy resources, like wood particularly for the heating of public buildings.

This boiler, with a power of 200 Kw, feeds a heat network providing the city hall, a associative space, housing, catering and a multi-field gymnasium. This latter was also redesigned in a high energy performance approach.

This boiler covers 90% of the heating and hot water needs of these different spaces. The extra is provided by the gas boiler of the city hall. This sharing, which produces no noise pollution, avoids the discharge of 133.8 tons of CO2 per year, the equivalent of 1,030,000 kilometers traveled by car.

This kind of heating also permits a financial gain for the city. With 3 centimes per kWh, wood is much more competitive than gas (5.5c €/kWh), fuel oil (9.5 c €/kWh) or electricity (11 c €/kWh). In this way, the city’s heating bill is reduced and permits a pay back period under 15 years. The 2 tons of ash from combustion are valued by market gardeners, nurseryman or the green space department of the city to improve soil fertility.

This report will be broadcast on Chengdu TV1 and will be an opportunity to promote French expertise in this area.
