Developing Products with High Environmental Performance

Simul Generator

Hybrid Floodlight

The Simul Generator incorporates independent windings forthree-phase and single-phase circuits to open the way for athree-phase output and a single-phase three-line output at thesame time. Without cumbersome switching operations, it isserviceable on a wide variety of sites.
With our conventional models, three-phase motors insubmersible pumps, compressors and other devices and singlephase loads such as lighting and air conditioners could not be
used at the same time without carrying and installing both athree-phase generator and a single-phase generator. This canbe done with just a single Simul Generator unit. It thus produceshigher environmental performance in terms of transport andinstallation.
In addition, it is equipped as
standard with an environmentallyfriendly base that minimizes fuelspillage outside the generator in theevent of fuel leakage. This allows it
to be used without concern nearrivers, harbors and elsewhere
where strict installation criteria apply.

DCA-45LSKE-D

The Hybrid Floodlight features a combination
between a battery and an engine. In considerationof the environment, it reduces noise and exhaustemissions.
While idle in the daytime, it recharges its battery.
While in operation for work at night, it consumes
the electricity stored in the battery to operate thelamps. It thus eliminates noise and exhaustemissions and enables work to be undertaken late
at night in consideration of the surrounding
environment.
When the remaining battery level falls to 10% orless as a result of lamp operation, it automaticallystarts up the engine generator to keep the lamps
lit while recharging the battery. When the battery
is recharged to full capacity, it automatically stops
the engine generator and works as a batterypowered floodlight.
With fuel consumption of at least 10% less thanour engine-powered floodlight, it is friendly to theenvironment in terms of fuel consumption as well.

Global Warming Prevention
Reduce CO2 Emissions
Denyo endeavors to prevent global warming through initiatives toreduce CO2 emissions due to business activities.
CO2 emissions in FY2015 were 5,058 tons, an increase of 4.3% fromthe FY2012 levels. This is because of the increase of conversion factor
for CO2 emission coefficients for power consumption, which aredetermined by electric power companies. Our power consumptionbefore conversion to CO2 emissions coefficients decreased 13.6% fromthe FY2012 levels. The amount of the consumption of fuels also
decreased 19.0% from the FY2012 levels.
We will continue to implement initiatives to cut CO2 emissions during
FY2015.

We manage and process solid waste appropriately and incompliance with all laws and ordinances.
In FY2015, we discharged about 334 tons of industrial waste,
down by 8.3% per output compared to the FY2012 levels, which is
far above the target.
We are also working toward a new target of cutting the volume ofindustrial waste per output by at least 15% compared to FY2012
levels by the end of FY2017.

Managing Chemicals Subject to PRTR
Based on the PRTR Law, we compile and release data on chemicals subject to the PRTR including amounts released into the environment ortransferred as solid waste.
*A Pollutant Release and Transfer Register (PRTR) is a system for compiling and disclosing data on hazardous chemical substances including
their sources, how much is released into the environment or transferred off-site with solid waste.

Environmental Measures at the Head OfficeControl

Denyo has been operating a building energy management system(BEMS) at its head office since FY2013 in a bid to reduce its peak
power consumption and achieve energy conservation.
BEMS is an energy management system that provides a visualpresentation of power consumption and other data in a building forheightening efficiency in the use of electric energy.
Paving the way for the automated control of air conditioning andother systems and for lowering peak power consumption, itcontributes to energy conservation and CO2 emission reduction.

Environmental Measures at Development Sites

Planting initiative
The Laboratory & Training Center has grass surrounding its building, and it carries
out trimming and other treatment of the vegetation around its premises. As a result,it has been certified by the Department of Environment of the Saitama Prefectural
Government to have formulated an excellent tree planting plan in recognition of thelayout, maintenance and management of plants. Apart from this, our head officealso conducts planting on its rooftop while our production sites push ahead with tree
planting and engage in the development and cleaning of weed zones.

Environmental Measures for Production Base
LED Lighting
At the Fukui Plant, the changeover of ceiling lighting from mercury
lamps to LED lamps is in progress.
Replacement with LED lighting helps cut energy consumption
significantly while maintaining light intensity. Lower power
consumption leads to lower CO2 emissions.
LED lighting generates limited heat from the lighting equipment andhas little impact on the room temperature. It helps boost the effect of
air conditioning in summer and slashes power consumption for nonlighting equipment as well.
Containing no mercury or other hazardous substances, LED lamps
are friendly to the environment and have a longer life span than
mercury lamps, thereby reducing the maintenance workload interms of lamp replacement.
Denyo will continue to strive toward cutting its environmental impact.
Five-S Initiative

Before tidying activities

After tidying activities

The Fukui Plant regularly carries out the five-Sinitiative.
The photos on the left show the pallet depot before
and after tidying activities. Differentiating what isnecessary from what is not needed and tidying up
what is necessary helps to prevent unexpected
accidents and increase work efficiency.
The Denyo Group will continue to improve its
workplace environment.
