Building sector

French-Japanese efficiency


ADEME has worked with NEDO (New Energy and Industrial Technology Development Organisation) since 2009. The two organisations met in Tokyo on 22 and 23 October to discuss a current challenge: improving energy efficiency in the building sector.

The partnership between ADEME and NEDO* is more relevant than ever. “Since the accident at the Fukushima power plant in April 2011, Japan has drastically reduced its reliance on nuclear energy and is searching for solutions that will enable it to end nuclear power generation all together”, says Nicolas Dyèvre, who heads cooperation between industrialised countries at ADEME’s International Action Department. “The proof can be seen in nuclear power consumption, which dropped from 288.2TWh in 2010 to 163 in 2011 and 187 in 2012, with long shutdown periods at all plants. Meanwhile, Japan is developing solutions to improve energy savings, an issue that has recently come to the fore in France with the Energy Transition for Green Growth bill. For the two organisations debating the topic, the day of discussion on these issues was therefore timely”, adds Nicolas Dyèvre.

One of the focuses of the meetings between ADEME and NEDO was energy efficiency in the building sector. “This topic was chosen for a reason”, stresses Nicolas Dyèvre. “The building sector is an area with the potential for major energy savings.” The event was organised in two parts: first the institutional discussions, then the presentation of promising French and Japanese technical solutions. “The initial discussions provided an update on how Japan and France plan to implement their energy efficiency policies”, explains Nicolas Dyèvre. “Later, companies with globally recognised expertise on the issue – including Bouygues, Saint-Gobain and EDF – presented their latest research findings”, adds Maeva Tholance, a specialist in high-performance buildings at ADEME. “But we also wanted to provide an opportunity for innovative SMEs such as Erie, Enersens, Parex and Syrthea, which were able to share their own technical solutions.”
The event also provided a forum to present three technologies support by ADEME as part of the Investments for the Future Programme:
• the CRIBA project, which enables building renovation on an industrial scale through the use of a prefabricated envelope made of wood and steel that can be affixed to any type of facade;
• the IBIS project, which uses bio-sourced insulation (including crushed hemp, sunflower, rapeseed and flax) to renovate old buildings;
• the VIPeR project, which develops interior thermal insulation with vacuum insulated panels.
