Home Ventilation System with IAQ Controller*15

Although it is important to ventilate rooms for a healthy lifestyle, conventional ventilation discharges air-conditioned room air outside, generating heat loss. This ventilation system recovers such thermal energy and returns it to the room with the fresh air taken in from outside.

In particular, the energy-saving performance of the system was enhanced by about five times in the heat transfer surface area of the heat exchange element and by about four times in moisture performance. This resulted in significantly improving the sensible heat exchange efficiency by 20% (when heating) and enthalpy transfer efficiency by 28% (when cooling). Further, adoption of the constant air volume controller for the DC motor fan reduced power consumption by 49% compared to our conventional model. Additionally, sensors for outdoor and indoor temperatures and humidity as well as precise control of air flow enable automatic control of the ventilation method (normal or energy recovery) and ventilation air volume according to the season, ensuring constant energy saving and comfort throughout the year.

This system has won the ECCJ Chairman Prize under the Product and Business Model Category in the Energy Conservation Grand Prize 2016.

Delivery Box for Detached Houses

The number of package redeliveries amounts to approx. two million every day in Japan. Not only the same number of delivery notice slips are issued, an additional 1,150 tons of CO2 is estimated to be emitted from the trucks used for redelivery.*16 This delivery box provides convenience for residents to receive a package even while they are away and contributes to environmental aspects by reducing CO2 emissions and delivery notice slips caused by redeliveries.

The release of COMBO, a delivery box for detached houses, started from April 2017. Because it allows providing a stamp of delivery proof and locking the delivery box without using any electricity, no electrical construction is necessary for installation or even during use.

In a field test conducted in Awara City, Fukui Prefecture, from November 2016 to March 2017, it was found that the redelivery rate was reduced from 49% to 8%, which is equivalent to a reduction of CO2 by 466 kg.

Household Fuel Cell

The ENE-FARM Household Fuel Cell provides high-power energy efficiency and conservation by generating electricity through an electrochemical reaction between oxygen in the atmosphere and hydrogen extracted from town gas, and can heat water with the heat generated from the reaction at the same time.
In July 2016, we launched a new fuel cell lineup for apartment blocks, developed together with Tokyo Gas. Apartment blocks have more restrictions than that for detached housing due to the specific nature of apartment buildings, including the limited installation space. For this reason, the lineup offers a model with an extended exhaust pipe in addition to the standard direct exhaust model. With this extended pipe, the fuel cell can be installed in a confined space where the airflow tends to be stagnant. The permissible piping distance between the hot water tank and the backup heat source device was also extended from 10 m to 15 m, enabling an installation layout in which the two components can be placed at each end of an apartment unit. The enhanced design flexibility of ENE-FARM surely will provide more opportunities for housing developers to utilize ENE-FARM in their apartment designs.
In March 2017 the total production of ENEFARM reached 100,000 units for the first time in the world.

Solar & Wind Powered Streetlight

A solar & wind powered streetlight converts natural energy from sunlight and wind into electricity using a solar panel and wind turbine, and stores the generated electricity in an accumulator battery. The wind turbine can supplement the power generated on a low sunlight day to ensure a stable electricity charge. During the night, the product lights the street with a bright and energy-saving LED lamp utilizing the electricity stored during the daytime. The product can also be programmed to light at full power for a specified period from sunset and switch to a lower light until dawn in order to make the best use of the limited electricity. Solar & wind streetlights not only utilize natural energy efficiently, but can be used during blackouts. It will play an important role as a security light for the community and as lighting in disaster evacuation points. The model with a power supply function provides emergency power for mobile phones, radios, and loudspeakers in emergency situations.
