Initiatives of the Housing CompanyHandover of disaster-affected area public housing to evacuees

In March 2016, Sekisui Heim Tohoku completed construction of disaster-affected area public housing for evacuees from the Great East Japan Earthquake built in the city of Higashi-Matsushima and held a ceremony to mark the handing over of the keys to the residents. Initially people were to have taken up residence in April 2016. However, having taken it as their responsibility as local businesses to construct the homes in a way that would give consideration to the providing of safe and comfortable homes for all who had been affected even one day sooner, onsite labor-saving was achieved by collaboration between the Miyagi branch construction groups and Tohoku Sekisui Heim Industry. They were able to hand over the keys before marking the fifth anniversary of the disaster. Designed to embody features that take into account the needs of the elderly and safety, such as wide modular baths and sensor-equipped porch lights, the public housing succeeded in bringing delight to all from its occupancy schedule. Through our business activities, we will continue to contribute to the reconstruction and revitalization of regions affected by the Great East Japan Earthquake.

Initiatives of the Urban Infrastructure & Environmental Products CompanyDonations to the Great East Japan Earthquake Miyagi Children's Scholarship Fund based on PVC pipe shipment volume from the Tohoku Plant

Five years have passed since the Great East Japan Earthquake, and reconstruction efforts are gaining momentum in affected areas. Under these conditions, in March 2015, we opened a new production plant for polyvinyl chloride (PVC) pipes in Watari, Miyagi Prefecture, the only such factory in the Tohoku region, in order to build a stable supply structure for our products. The PVC pipes made at this plant are inscribed with the words Stay Strong Tohoku! as a symbol of our approval of the Stay Strong Tohoku campaign being promoted by the Ministry of Land, Infrastructure and Transport and Tourism in the Tohoku Regional Bureau. Over the one-year period starting in April 2015, for each shipment of those pipes we will donate ¥2 to the Great East Japan Earthquake Miyagi Children's Scholarship Fund operated by Miyagi Prefecture. In April 2016, we visited the government offices of Miyagi Prefecture and made a donation.

Initiatives of the Urban Infrastructure & Environmental Products CompanyNew energy joint research leading to the creation of post-reconstruction towns

In the city of Sendai, Miyagi Prefecture, which was an area affected by the Great East Japan Earthquake, advances are being made in the creation of sustainable cities as well as in research into energy savings and new energy that are leading to reconstruction and beyond. As part of that research, the Urban Infrastructure & Environmental Products (UIEP) Company has been conducting experimental studies jointly with the city of Sendai to effectively utilize heat energy taken from sewage conduits since 2013. Utilizing Sekisui Chemical’s underground water helix-type Esloheat sewage heat recovery system, the research improves the ability of the sewage conduits to withstand earthquakes, making them more resilient, at the same time as adding heat recovery functions. Utilized for the research is the first private commercial facility in Japan to have recovered heat. The research up to March 2015 verified energy efficiency, cost and other aspects, as a result of which it was found that savings of more than 30% a year could be made on electricity bills. Continuing in fiscal 2015, UIEP engaged in efforts toward the wider adoption of the system and conducted verifications related to the management of sewage conduit maintenance after installation.
