The Japan 2×4 Home Builder Association reported another strong year for fireproof building approvals with 275 applications being processed for a combined total floor area of 88,240 m² for the fiscal year 2014 (289 units for an combined total floor area of 98,875 m² in fiscal 2013). Since COFI and the Japan 2×4 Home Builder Association received a platform frame fireproof ministerial approval in 2004 from Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT), 2,581 applications have been processed for a combined total building floor area of 650,136 m² worth of fireproof buildings in Japan. In terms of combined project total floor area by market segment since securing the ministerial approval, the non-residential market was first (230,636 m²), followed by the detached single-family homes (227,981 m²) and thirdly by multi-family market segment (191,519 m²). For comparison purposes, a breakdown for fireproof approvals in fiscal 2014 in terms of the number of projects and combined floor area broken down by market segment can be found in the table below.

For fiscal 2014, the non-residential market segment had 21 project approvals processed for a total combined floor area of 43,797 m² for the period. This market segment now represents about half of the fireproof approvals in Japan in terms of total building floor area. As outlined in the past the majority of these buildings are elderly care facilities (17 projects), a medical facility (1 project) and commercial buildings (3 projects). The accumulative total of fireproof elderly care projects build in Japan since 2004 currently stands at 115 units.
