Housetec Inc.

Enhance Environmental Safety Management Level by the Use of Environmental Safety Management Reports

 Housetec prepares original Environmental Safety Management Reports that cover all management items concerning the environment, safety and health, disaster prevention and chemicals management. Based on reports prepared by respective manufacturing departments every fiscal year, the environmental safety department conducts safety audits. Documentary inspections and on-site inspections are carried out in reference to the Guidelines on Occupational Safety and Health Management Systems. Auditors check compliance with relevant laws and regulations, obtainment of safety ratings, satisfaction of required personnel with legal qualifications, and achievement of original targets of Housetec.

 Additionally, follow-up audits are also conducted to check improvements in the situations identified in the first audit findings, thereby attempting to promote intrinsic safety and strict compliance with environment-related laws and regulations in order to enhance the overall environmental safety management levels.

Consideration for the Environment in Distribution Process

 Housetec has promoted cooperation with distribution companies to develop transshipment bases and the shift of 2t trucks to pickup trucks with the aim of reducing CO2 emissions.

 Furthermore, the company is attempting to ensure efficient energy use through improving loading efficiency, by such means as designating delivery time with some margins: for example, from 9:00 a.m. to 10:00 a.m., instead of specifying an exact time such as 9:00 a.m. sharp, to reduce the number of necessary vehicles and enable one vehicle to deliver goods to multiple locations. The company is also changing the conventional system under which 2t trucks transported goods all the way to destinations, by developing a transshipment warehouse to which goods are transported efficiently using 10t trucks. In this manner, the company aims to further improve loading efficiency and shorten total travel distances for distribution.

Promotion of the Dissemination of Photovoltaic Power Generation Systems

 Yamada SxL Home and Yamada Wood House have been proactively promoting the dissemination of photovoltaic power generation systems for general houses.

 Due to the reduction in feed-in tariff purchase prices, among newly built houses of Yamada SxL Home in fiscal 2015, the percentage of those installing photovoltaic power generation systems was 47.3%. The company will make further efforts in fiscal 2016 to promote the dissemination of photovoltaic power generation systems by actively making proposals to customers concerning net zero energy houses upon constructing new houses and installation of photovoltaic power generation systems upon renovating houses.

 Yamada Wood House has prepared a system to enable installation of solar panels on almost all houses, except for cases where there are constraints due to sunshine conditions or other legal constraints, and has promoted aggressive sales activities. Furthermore, the company also commenced promotion activities of net zero energy houses (ZEH), highly environmentally-friendly initiatives, and has already completed and delivered such houses to customers. The company will further strengthen proposals to customers.

Wood Use in Consideration of Conservation of Forestry Ecosystems

 In order to conserve the global environment and sustainably develop forests, Yamada SxL Home and its group companies have endeavored to secure the legality of wood they use for structural members and establish a traceability system. In fiscal 2015 as in the previous fiscal year, such efforts were made for structural members for the SxL method (method using wooden adhesive panels), which accounts for 87.4% of the company’s housing business.

 Wood used for the SxL method is divided into dimension lumber (twoby- four lumber) and plywood, and is further divided into dimension lumber for adhesive panels, dimension lumber for laminated lumber, unprocessed dimension lumber to be used for rafters, plywood for adhesive wall panels, plywood for adhesive floor panels, and sheathing plywood to be used for roofing boards.

Houses Built by Kobori in Mefu and Tri-vert Izumi Subdivisions

 The concept of the Mefu Subdivision in Takarazuka developed and sold by Yamada SxL Home is a “town friendly to nature, community and residents.” In order to create a beautiful view, the company tried to secure 50cm green strips along roads and selected and planted symbol trees to create unique spaces for each of them. In fiscal 2016, kobori Kenchiku Kobo, a professional architect company, completed four original one-of-a-kind houses with the focus placed on the beauty of form and shape, individuality and functionality.

 The Tri-vert Izumi Subdivision is located on a moderate slope running down to the southwest from the entrance and commands an extensive view of distant mountains. Roads within the subdivision moderately curve to soften a feeling of oppression due to lines of outer walls. Gates are installed one meter or more back from roads and symbol trees and other greenery are planted to create a spatial streetscape. In fiscal 2015, kobori Kenchiku Kobo, a professional architect company, completed two houses in the subdivision.

Development of Housing Business Adopting “Leaf to Home”

 Yamada Wood House proposes the adoption of “Leaf to Home,” an idea to utilize a Nissan Leaf Electric Car as a storage battery (24 to 30kW) to store inexpensive night-time power and use power thus stored at home during daytime, when power charges are high. The car, which can store power for two days, is also usable in an emergency. By selling the Leaf (battery) and a house as a set, the company proposes further reduction of power consumption.

Azuma Metal Co., Ltd.

A Class on the Environment at the National Museum of Nature and Science

 The National Museum of Nature and Science (Taito-ku, Tokyo) holds science navigation classes twice a month to raise people’s interest in science. As in the previous year, Azuma Metal also held classes on the environment and recycling at the science navigation corner on April 1, 2015. One of the classes was the one titled “Let’s Learn the Mechanism of Metal Recycling! Art Works of Unique Figures Using Scraps.” The company holds this class continuously with active support by the museum staff members, who offer cooperation such as preparing signboards and placing related books in the center of the reference corner.

Started Selling Power Generated with Photovoltaic Power Generation Systems

 Azuma Metal installed photovoltaic power generation systems on its land in Furuto-cho, Ota-shi, Gunma, and started to sell generated power.

 The total area is 13,700m2 and the output capacity is 1,000kW.

 The company effectively utilizes a vacant lot it owns to create environmentallyfriendly natural energy.

Environment Classes Deeply Rooted in Local Communities

 In fiscal 2015, the company visited a total of 10 local elementary schools and junior high schools and provided open classes with the aim of having children and students (i) learn about recycling of their familiar articles while having fun and (ii) gain an understanding of occupations in the environmental and recycling-related industries.

 In order to have them enjoy learning about 3R (reduce, reuse, recycle), quizzes and videos are used and participants experienced sorting of garbage in the first half and then created art works with scraps on drawing paper in the latter half of the clas ses . The company received good feedback from teachers and guardians that children and students could learn about recycling from their own points of view.

TOPICSReceived the “Osaka Stop Global Warming Award”

On February 16, 2016, the awards ceremony of the “Osaka Stop Global Warming Awards” was held at the Osaka Mayor’s Mansion (Osaka-shi, Osaka). LABI1 Nanba store was awarded the Power Conservation Award.

Based on the Osaka Prefectural Ordinance on the Prevention of Global Warming, the “Osaka Stop Global Warming Awards” commend entities that have made particularly outstanding efforts serving as a model to other entities with regard to the reduction of greenhouse gas and anthropogenic heat emissions and the leveling of power demand in their business activities.

The Yamada Denki Group will continue its efforts to reduce environmental load and create a recyclingoriented society as part of its CSR activities.
