Commencement of Sales of “OTS House”
Realizing Complete Self-sufficiency in Water/Electricity
TOKAI CORPORATION (headquarters: Shizuoka City, Shizuoka Prefecture, Representative Director andPresident: Katsuo Oguri, hereinafter “Company”) has been conducting a demonstration work of conceptual
housing “OTS House” since October 2017. OTS House is an image of a near-future housing where complete
self-sufficiency in water and electricity is realized to ensure a normal life as usual even in the face of power
and water outage due to disasters and other phenomenon.
The Company is pleased to announce that OTS House has been commercialized based on the data and knowhow obtained from the demonstration work, and that sales will be launched from July 23, 2019.
1.

Overview
The Company and each TOKAI Group companies provide a wide range of lifestyle infrastructureservices that are closely related to the lives of our customers such as gas, the internet, CATV, Aqua(bottled water delivery), and electricity. Furthermore, in the field of residential environment, the Groupis engaged in housing and renovation businesses, expanding the TLC (Total Life Concierge) concept
which provides comprehensive support to our customers’ lives.
In the course of further expanding each service, the Company had been working to formulate a houseequipped with functions required in the current and near-future social environment. As a facility toembody this, development of conceptual housing “OTS House” was advanced in Shimada City,Shizuoka Prefecture. OTS House was completed in October 2017, and since then, demonstration work
continuously has been made with a focus on OTS House’s primary function, a function realizing
complete self-sufficiency in water and electricity.
In particular, a family of four was assumed to recreate the situation of water and energy use. Then,detailed data were collected and analyzed to verify the feasibility of self-sufficient functions, optimizing
facilities and equipment which compose them from a perspective of environmental performance andeconomic efficiency. Furthermore, in parallel with the demonstration work, the Company welcomed
visitors from housing manufacturers, building firms, facility manufacturers, researchers involved inenergy and environment, local residents, and consumers who were interested. As a result, variousopinions and suggestions were obtained from them. (Number of visitors exceeded 500 as of July 2019)
Based on the optimized facilities obtained through the demonstration work, and opinions and others
received from all the visitors, the Company started the development of the OTS House with an eye
toward commercialization. Sales will be launched to the general public from July 23, 2019.
The Company will actively offer and sell OTS House with an aim to establish it as a new style ofJapanese housing.

Basic concept and main functions of OTS House
The name “OTS” stands for “On the Spot,” indicating the basic concept of housing where one isprotected and feels secure by just being there. The Great East Japan Earthquake and 2016 Kumamoto
Earthquakes significantly changed the awareness of security for lifeline services and basic daily life
infrastructure in Japan. The house envisioned here is where a normal life is ensured even wheninfrastructure such as water and electricity are cut off in case of disasters, and where usual everyday life
is more secure, safe, convenient, and economical through the TOKAI Group’s one-stop services whichcover each and every lifestyle infrastructure.

OTS House which will be put on sale from July 23 also complies with this basic concept. In addition to
the three pillars of function (a house securing water supply, electricity supply, and a living) which
continuously have been disseminated since the construction of this conceptual housing, a concept of “ahouse securing families” has been raised in areas including housing structures and floor plans, andreflected in the designs.
(1) The House securing water supply
OTS House realizes domestic water self-sufficiency whichutilizes rainwater and does not depend on waterworks system.
Rainwater that falls on the building and on the ground of OTS
House is collected and stored in a rainwater tank with amaximum capacity of 17,000 liters. It is then generated as
domestic water through an RO (reverse osmosis membrane)water purification system, and supplied to the building. In
addition, part of domestic wastewater discharged is purified andrecirculated as domestic water. This realization of domestic water
circulation has reduced domestic wastewater of generalhousehold by approximately 40%. Therefore domestic water selfsufficiency is achieved with rainwater.
This system which realizes domestic water self-sufficiency withrainwater was commercialized through a joint research withDaigaku Sangyo Co., Ltd. (Headquarters: Hamamatsu City,
Shizuoka Prefecture; Representative: Yoshiyasu Sobukawa),
Aqua Design System Co., Ltd. (Headquarters: Kochi City, Kochi
Prefecture; Representative: Ryosuke Takeda), and the Company.
Patent has been applied as an “architectural structure enabling
domestic water self-sufficiency with rainwater as water source.”(Patent Application Number: 2019-44286)(2) The House securing electricity supply
OTS House realizes electricity self-sufficiency which furnishes
large-volume solar panels and large-scale storage batteries anddoes not depend on grid power. The building is designed to allow
installment of solar panels as many as possible. Its power
generating capacity is 9.36kW, approximately two to three times
larger than that of conventional homes.
Furthermore, to respond to the electricity demand during thenighttime, and to be self-sufficient even when electricity
generated from solar panels are few due to situations such as badweather, OTS House is equipped with large-scale stationary
storage batteries with an overwhelming storage capacity of48kwh, approximately ten times larger than that of generalemergency storage batteries (storage capacity: 3kwh to 5kwh).
Storage batteries have been installed to OTS House by Variostor
Corporation (Headquarters: Takamatsu City, Kagawa Prefecture;
Representative: Masatoshi Mitsuya) with which the Company has
built cooperative relationship and jointly conducteddemonstration work. In addition to its storage, OTS House is able
to supply consumption electricity to residential buildings up to ageneration capacity of 10kvA (equivalent to 100 ampere) in timesof power outage.

(3) The House securing families
The design concept of OTS House is a “house securing families”.
In both the first and second floor, spaces for the family such as
the family room and bedrooms are located in the center. In
addition to the exterior walls, facilities, furniture, halls, andstairways are arranged as if they are “another piece of wall”. The
double wall heightens a sense of security from a perspective ofcrime-prevention and privacy. Furthermore, a family room iscreated on the first floor and a “library available for all family
members” on the second floor, facing the outside similar to averanda. By creation a common place where family members canget together, OTS House is designed to make possible reductionof energy consumption such as in lighting and air-conditioning ina natural way.
This concept and basic design was formed under thecollaboration between Tsubame Architects Inc. (Headquarters:Shinjuku-ku, Tokyo; Representative: Takuto Sando) and theCompany.
(4) The House securing a living
OTS House realizes one-stop support by covering various
lifestyle infrastructure services which the TOKAI Group offers
while proposing economic advantages. For example, liquefied
petroleum gas (LP gas) has come under the spotlight again as
distributed energy resource that can be stored as a stockpile. In
the communications and broadcasting area, ultra-high-speed
internet access with a maximum transmission speed of 10 Gbps
and high-definition 4K broadcast are available. Moreover, thebottled water delivery service regularly provides safe drinking
water (water dispenser) with satisfaction, and the cutting edge
home security service protects the family and the building. OTS
House offers safe, secure, and convenient lifestyle in a style truly
embodying the concept of TLC.
The Company’s support staffs will regularly perform
maintenance works of OTS House, namely on self-sufficiency
functions, water quality of domestic water, housing/individual
facilities and equipment.

Lineup of OTS HouseOTS House marketing will be promoted from two sides - sales of standardized housing, and package
sales of facilities realizing self-sufficiency in water and electricity.
(1) Sales of standardized housing
OTS House will be sold as an all-in-one type standardized house, and as a near-future house
where water and electricity essential for life is completely self-sufficient, ensuring a normal life
even in the face of water and electricity outage.
Line up of standardized housing comes in the following four types: (a) Advance type which is thecore model realizing complete water and electricity self-sufficiency, (b) Water Conscious typewhich emphasizes water self-sufficiency while reducing initial cost, (c) Energy Conscious typewhich emphasizes electricity self-sufficiency, (d) Value type which is most affordable but realizes
self-sufficiency for approximately seven days in times of water and electricity outage. The best
type will be proposed according to customers’ needs.
3Sales of standardized housing will initially be expanded in areas within Shizuoka Prefecture, but
by developing alliances with housing manufacturers and building firms in the future, will aim to
expand in broader areas.
