LIXIL makes pioneering water and housing products that solve everyday, real-life challenges, making better homes a reality for everyone, everywhere.
We have set out to achieve net-zero greenhouse gas emissions from business processes, products, and services.
We provide products and services with improved home insulation that help reduce heating and air conditioning demand as well as ones that use renewable energy. We also provide IoT-enabled solutions for eco-conscious lifestyles and solutions that address natural disaster and health risks of climate change.
LW is an innovative window product consisting of a large glass door that slides open sideways and a built-in frame that is almost invisible from inside the house. This product offers high thermal insulation (heat transmission coefficient 1.00W/(m2K))* through its aluminum-resin hybrid frame, which helps reduce CO2 emissions and energy consumption from heating and air conditioning. The built-in frame provides a clear, wide view, and is designed to perfectly fit the lines of the window frame. LW won the Nikkei Sangyo Shimbun Award of Excellence at the 2018 Nikkei Superior Products and Services Awards, along with the 2019 Construction Materials and Facilities Grand Prize.
* Calculated internally using JIS A 2102-1 and JIS A 2102-2 standards for measuring the two-way thermal transmittance of Low-E green (5-10-1.3-11-5) model of sliding 16522 triple-pane glass (with krypton gas).

Heating water constitutes 24% of household CO2 emissions. Reducing the amount of hot water used, therefore, is an effective way to reduce emissions. The impeller built into the Ecoful Shower’s showerhead is designed to close off half of the showerhead’s holes while spinning at a high speed. As a result, the increased internal pressure creates a powerful shower spray despite using considerably less water. In fact, this showerhead can reduce the amount of water used by 48% compared to traditional shower heads (10 liters/minute), thereby saving energy.
The growth of online shopping in recent years has increased the number of home deliveries. However, due to the growing number of redeliveries as well, this is cited as reducing labor productivity and increasing CO2 emissions. LIXIL launched its IoT-enabled Smart Post Delivery Box in 2018, which enables two-way communication between the box and a smartphone, sending notification of deliveries and enabling users to accept multiple separate deliveries. In a demonstration experiment conducted in 2019 in the Koto and Edogawa districts of Tokyo, we confirmed the benefits of this product in cutting emissions through fewer redeliveries, and plan to expand the product lineup going forward.
To help reduce household energy consumption, the Japanese government has set a target requiring over 50% of new houses built by 2020 to qualify as ZEHs.* ZEHs are not expanding at the desired pace, though. To help address this situation, LIXIL Corporation and TEPCO Energy Partner, Inc. established a joint venture company, LIXIL TEPCO Smart Partners Incorporated (LTSP), in September 2017.
The company leases solar-power generation systems to customers who purchase LIXIL’s ZEH materials, and receives income from any surplus energy sold. In return, the actual cost customers pay each month for their solar power generation systems is zero yen. LTSP’s new Tatetoku Value service, which was launched in 2018 to help reduce customers’ monthly electricity bills, won the Agency for Natural Resources and Energy Director-General’s Award at the FYE 2019 Energy Conservation Awards. We intend to use these services to promote the spread of ZEHs, help customers live comfortably and healthily, and help mitigate global warming.
* Stands for net zero energy houses. ZEHs realize both a comfortable indoor environment and a substantial reduction in energy consumption with high insulation and high-efficiency equipment. A ZEH also produces energy with a solar or other power generation system, thereby reducing the annual net amount of energy consumption to almost zero or less.
We are promoting strict energy-saving activities in factories and offices, the development of energy efficiency technologies, and use of renewable energy.
We aim to increase energy efficiency in manufacturing through site-specific initiatives, such as by identifying issues in production processes and conducting equipment reviews.
The Otani Plant in Aichi, Japan, for example, installed flow meters to quantify steam use, making it possible to identify the location of leaks. In FYE 2020, it reduced steam use by 44%, equivalent to 1,089 metric tons of CO2. The Shimotsuma Plant in Ibaraki, Japan installed an IoT-enabled monitoring system on its combustion furnaces, which were difficult to improve due to a safety concern. This system enabled more suitable operation of the furnaces and a reduction in fuel use.
The Hokkaido Distribution Center in Japan began combining freight with other companies in the industry to address poor loading efficiencies and a driver shortage — issues faced across Japan. This helped reduce combined driving distance with partner companies by 55,200 kilometers annually, a 22.7% reduction in CO2 emissions intensity per tonne-km. We are also replacing existing lighting at our Japanese factories and distribution centers with LED lighting. At least 95% of lighting has already been converted to LED.

We are also focused on using renewable energy to reduce CO2 emissions.
LIXIL Corporation is generating and promoting the use of renewable energy by operating megawatt-scale solar power plants in previously unutilized spaces at eight manufacturing sites in Japan. Together, these eight sites generate some 33,800 MWh of electricity annually, enough to power approximately 6,800 Japanese households.
In FYE 2020, all GROHE production sites achieved a shift to renewable energy, reducing CO2 emissions by 48,000 metric tons annually. We also converted to 100% renewable energy at the LIXIL headquarters, Kyoto showroom, and INAX MUSEUMS, achieving an annual carbon reduction of 2,000 metric tons. We plan to continue shifting to renewable energy across the entire LIXIL.
