Sekisui House exceeds target production of Net-Zero Energy homes

10 April 2020

Sekisui House has exceeded its own targets with Net Zero Energy homes accounting for 87% of its newly built detached homes, the highest in Japan for the fourth consecutive year.*1

In fiscal 2019, 87%*2 of newly built detached homes constructed in Japan by Sekisui House were Net Zero Energy Houses (ZEH), enabling the company to reach its fiscal 2020 target of 80% ahead of schedule. As of March 31, 2020, ZEH detached houses sold under the Green First ZERO model launched in 2013 totalled 51,793.

In the collective housing category, Sekisui House supplied 447 Net Zero Energy Apartments in 58 buildings in fiscal 2019, for a cumulative total of 691 units in 103 buildings.*3 Combined CO2 emission reductions in the detached home and collective housing categories due to ZEH construction amount to approximately 710,000 t-CO2,*4 making a major contribution to global warming prevention.

As well as being effective in preventing global warming, ZEH housing is drawing attention for its high levels of disaster resilience. Sekisui House has been a leader in enhancing the resilience of housing, being the first company to adopt storage batteries as standard in its housing and launching energy-saving and disaster-ready housing as early as 2004. In 2011, the company launched its Green First HYBRID model, becoming the first in the world to coordinate control of three types of battery: solar cells, energy-creating fuel cell ‘Ene-Farm’, and storage cells. Since 2013 it has promoted the Green First ZERO model of energy-neutral housing.

When earthquakes and typhoons struck, Sekisui House made maximum use of its nationwide group network and its own disaster response systems to provide various forms of support enabling homeowners to return to their normal daily lives as quickly as possible. Based on the concept of enhancing all-round resilience through the Sekisui House Group’s disaster support systems, in addition to bolstering the resilience of housing itself, Sekisui House promotes housebuilding that contributes to global warming prevention and preparedness for devastation associated with climate change and aims to be a leader in ESG management.
