What is ZEB?

Environmentally friendly buildings using natural energy ZEB is the acronym for (net) zero energy building, where its

energy consumption is reduced to near zero. Toda Corporation

is committed to realizing a building that produces all the

energy it needs from renewable sources such as solar, wind

and geothermal power, adopting advanced energy-saving

technologies.

Four key elements of ZEB

The Toda Building Aoyama, which was completed in March 2011, is a medium-

sized, environmentally friendly tenanted building boasting a 40% reduction in

CO2 emissions (from 2009 levels), a breakthrough a few years ago.

The building is equipped with double-skin curtain walls designed to reduce the

amount of solar radiation, radiation air conditioning systems, desiccant air

conditioning systems, transmissive solar cell modules, geothermal heat

pumps, optical ducts, lighting fi xtures with motion sensors, etc. With fi fty

environmentally conscious technologies adopted, it obtained the highest level

of certifi cation such as CASBEE (S Class) and the Tokyo Green Building

Program System 3-3 (AAA).

It is a fl agship project involving environmental technologies while data is being

collected and verifi ed to implement a ZEB commercialization project in 2020

through evidence-based design (EDB).

Modern buildings consume energy to support sophisticated business

and people’s lives. The Great East Japan Earthquake, meanwhile,

had a devastating impact on Japan’s energy supply.

In response, the government announced the Basic Energy Plan on

April 11, 2014, which ultimately aims to realize net-zero energy public

buildings by 2020 and encourage wider adoption of ZEBs, targeting

2030.

We must therefore make further efforts and contributions to fulfill the

plan.

Converting natural resources into energy ● ● ● ●

Green energy

Power generation business capitalizing on the renewable feed-in tariff scheme is booming nationwide.

Toda Corporation’s services are wide-ranging, from land reclamation to cradle installation, regulatory compliance (in the planning stage), stakeholder coordination, foundation engineering, and design and installation of solar panels. Leveraging its experience in power generation business (including the mega solar power plant in Tadehara), moreover, we also provide operational services.

The total area of Japan’s exclusive economic zone is ranked sixth in the world. Offshore locations, where there is a constant strong wind, have great potential for wind power generation. In particular, floating wind power plants are suitable for the seas near Japan, where the water depth drops rapidly. The demonstration plant is designed to collect data on environmental impacts and safety as well as the knowledge required for commercial operation including maintenance and inspection. Toda Corporation is committed to commercializing offshore floating wind power generation.

● ● ● ●

Mega solar power plantFrom planning to design, procurement, construction and operation

Japan is rich in forest resources, which have not been fully used. The forest industry is thus declining, resulting in the degradation of forests.

Toda Corporation is focusing on biomass power generation to solve these problems, tapping unused biomass resources such as tree thinnings – Japan’s valuable energy sources – to restore forests and help create a recycling-oriented society.

In addition to wood materials, other biomass resources such as livestock wastes and garbage are being used for power generation.

Offshore floating wind power generationA wind power plant floating on the sea

As part of the demonstration of offshore floating wind power generation, a project sponsored by the Ministry of the Environment, Japan’s first offshore floating wind power turbine (2.0 MW) is in operation off the coast of Kabashima Island, Goto City in Nagasaki. It is 172-m long and 96-m high above sea level. Its floating structure has a maximum diameter of 7.8 m and weighs about 3,400 tons.

The mega solar power plant in Tadehara, Nagasaki, built on the site of a golf course with an area of about 28 ha, has an installed capacity of 13.2 MW. Toda Corporation is one of the owners of this power plant, taking charge of the design and construction of it. It is scheduled to start selling electricity in April 2015.

Toda Corporation is promoting biomass power generation in cooperation with Japan Blue Energy Co., Ltd. which specializes in biomass gasification power generation. The demonstration plant shown in the picture uses wood chips to produce hydrogen and heat in addition to electricity, part of which is supplied to communities near the plant.

Environmentally friendly construction

Eco-construction ● ● ● ●

The way electricity and thermal energy are consumed differs from building

to building. An energy network is a system where buildings are connected

with one another through cables and pipes to average out energy

consumption and exchange surplus energy. For example, energy

consumption in offi ces and commercial facilities peaks during the day

and decreases at night, which is usually the opposite for housings. Power

consumption peaks can be smoothed by exchanging electricity between

the two sectors.

● ● ● ●

What is an energy network? Supplying surplus energy to other buildings

New hospital energy network

Kawamata-machi reconstruction project

Biodiesel fuel (BDF)

CO2 emissions from construction account for

about 90% of those released by construction

companies. Toda Corporation, therefore,

developed the low-carbon construction system

TO-MINICA, which is designed to calculate the

amount of CO2 emissions from construction

and help draw up reduction plans.

In 2000, zero emission was achieved for the fi rst time in the construction industry for the

construction of the Canal Wharf Towers. Zero emission efforts are underway at other building sites

by reducing and segregating waste.

Zero emission Reducing construction waste

An energy network centering on the Saitama Cancer Center is in operation to significantly reduce the environmental load (reduce CO2 emissions by 35% from previous levels).

We are building a depopulated smart community in Kawamata-machi to support Fukushima reconstruction efforts. The plan is to capitalize on renewable energy and create an energy network primarily for community facilities. Renewable energy will also be used to generate power, which is expected to create new industries and employment opportunities.

Edible oil, a raw material for biodiesel, is derived from rapeseed, soybeans, etc., which absorb CO2 during growth (photosynthesis). The amount of CO2 released during combustion of BDF is therefore counterbalanced.

Eco-communication

We are committed to “regenerating biodiversity in a creative way”

through construction business while working in harmony with

biodiversity. For example, we are conducting monitoring surveys

on biotopes in schools in Tokyo and on an urban ecological

network at the rooftop garden on the headquarters building. The

resulting monitoring data serves as the basis of design,

construction and technical proposals.

We are making concerted efforts to conserve the environment,

recognizing the importance of the conservation and sustainability of

biodiversity. Specifically, we are engaged in studies to minimize

impacts on the growth of fireflies and conserve their habitats.

We visit elementary schools to keep students informed of our

environmental activities. For example, we have been providing

various educational programs to the students of Joto Elementary

School (Chuo-ku, Tokyo) since 2010, targeting the fifth and sixth

graders. We also demonstrated the production of BDF in a science

class to communicate the importance of recycling to the students of

Matsuhidai Elementary School (Matsudo, Chiba) and Makinohara

Elementary School (Matsudo, Chiba).

With focus on offshore floating wind power generation, meanwhile,

we provided hands-on experience in making paper crafts of floating

wind power generation units at events such as the Eco-products

Exhibition, environmental workshops sponsored by the Suginami

Ward Office and the 2014 Learning Festival.

A number of children take part in these events to learn about the

importance of energy and deepen their understanding of natural

energy.

Environmental education capitalizing on what is unique to construction business

A rooftop garden opened in April 2014 on the rooftop of the headquarters building with the use of our proprietary “biodiversity assessment system.”

An indoor biotope called “Hotaruarium” is designed to monitor the ecology and habitat of f ireflies.

Many students listen intently to lectures at schools and events.

Environmentaleducation

Every year, the fifth and sixth graders learn about the environment

with the help of Toda Corporation. In fiscal 2013, for example,

they learned about offshore floating wind power generation and

assembled a miniature floating wind power generation unit to

demonstrate it.

They also learned about BDF (biodiesel fuel) in fiscal 2014 and

converted used tempura oil (waste edible oil) into biodiesel to drive a

diesel engine. These activities help them get interested in nature and

science and technology while providing them with opportunities to

think about nature and environmental conservation.
