Ensuring heat insulation and energy-saving performancethat exceeds the latest ZEH standards“Sumitomo-Fudosan-no-SUMICA” is launched
Sumitomo Realty & Development Co., Ltd. (Head office: Shinjuku-ku, Tokyo, President: Kojun
Nishima) will launch the sale of “Sumitomo-Fudosan-no-SUMICA” on April 29, which exceeds thelatest ZEH (Net Zero Energy House) standard, following the establishment of the new ZEH level of“thermal insulation performance grade 5” and “primary-energy consumption grade 6” in April thisyear by the Ministry of Land, Infrastructure, Transport and Tourism, with the aim to improve theenergy-saving performance of houses towards realizing a carbon neutral society
The government aims to achieve the ZEH energy-saving standards for new houses and installsolar power generation equipment in 60% of newly built detached houses by 2030. In fiscal year
2020, however, only a fourth of all custom-built detached houses met ZEH standards*1 and only
10% to 20% of houses are equipped with solar panels, which are essential for ZEH*2. One of thereasons for slow implementation is considered to be high initial cost.*1
From September last year, we began to offer SUMIFU X ENEKARI, which enables theinstallation of solar panels, storage batteries, and AI-HEMS at no initial costs thereby raising oursolar-panel use to approximately 60%. Sumitomo-Fudosan-no-SUMICA, standardizes SUMIFU X
ENEKARI as a basic service, and incorporates advanced materials such as high-insulationmaterials and triple glazed window frames*3 as standard features in order to ensure performancethat exceeds the ZEH standards. We offer secure, safe, and comfortable living for homeowners by
reducing their daily energy use and preparing for disasters that may cause power outages.

and the environment“Sumitomo-Fudosan-no-SUMICA” image【Our Initiatives for Carbon Neutral Society】
In addition to the above-mentioned initiative in our custom home business, we are promoting
various initiatives across our businesses towards achieving a carbon neutral society. In our officebuilding leasing business, we have started offering the “Sumitomo Realty’s Green Power Plan,”which enables tenant companies to select the most appropriate green power plan from among
several methods. In our condominium sales business, we have decided to adopt “ZEH-M Oriented”
energy-saving performance as the standard, as well as to request the use of green power at theconstruction site. In our housing remodeling business, we have started offering “High Thermal
Insulation Remodeling Plan” and “SUMIFU X ENEKARI.”*1: Resource “Net zero energy house demonstration project presentation 2021”, Sustainable Open Innovation Initiative*2: Material from the sixth meeting of study group on energy-saving measures for houses and buildings toward a carbon neutral society*3: Double glazing window frames may be used in certain fire-prevention zones

～Features of “Sumitomo-Fudosan-no-SUMICA”～
1．Advanced Energy －ZEH energy-saving performance as the standard－With high thermal insulation and shielding performance, it
maintains comfortable room temperature, cool in thesummer and warm in the winter. In addition, by utilizing
renewable energy with solar power generation and storage
battery system, it realizes an energy-saving house.
■ Energy saving through high thermal insulation performance■ Energy creation with solar power generation system■ Storage batteries to store the energy generated《 About ZEH (Net Zero Energy House)》
ZEH refers to a house in which the energy balance isreduced to virtually zero through reducing energy
consumption by improving the thermal insulation of thehouse and using energy-efficient equipment/devices, aswell as generating power using solar power generation andother means.

Balance of energy consumption■Sumitomo-Fudosan-no-SUMICA exceeds the government’s ZEH standards*1: The figures are based on our model plan (approximately 16.2 m2), in which the opening area is reduced to curtail heat loss. The figures are not guaranteed.

■Initiatives for high thermal insulation and energy saving

The house fully utilizes the advantages of wood, which has excellent thermalinsulation properties. In addition, the entire house is wrapped in glass wool,
which is a high-performance thermal insulator, to achieve superior insulation
performance.

Feature 1 battery and provide “long-term” support service for continuous peace of mind
"SUMIFU x ENEKARI" is an industry-first service*² that provides customers with peace of mind throughsemi-permanent use of solar power generation. With the payment of a fixed service fee only, it installs
solar power generation equipment and storage batteries at a "zero initial cost," and provides support
including equipment repairs and upgrades for the entire period of residency.

Feature 2 Toward achieving a carbon neutral society by reducing greenhouse gas emissions
One characteristic of solar power generation is that it produces clean, endlessrenewable energy. The introduction of a solar power generation system for"energy creation" and storage batteries for "energy saving," combined withhigh insulation and airtight specification of the house, makes it compatible withzero-energy housing (ZEH).
