Alnet Home / Taiga Kensetsu Co., Ltd. (Headquarters: Omiya-ku, Saitama City, Saitama Prefecture, President & CEO: Ryo Suga, hereafter Alnet Home), a custom home builder, announced that its high-performance home 'Gokudan no Ie' has won the [Special Excellence Award] in the 'House of the Year in Energy 2025', an award system by the Japan Regional Development Center that selects top runners in energy-saving housing. This marks the company's 12th consecutive year winning the award since its first participation in 2014.
● What is House of the Year
This is an award system sponsored by the Japan Regional Development Center that evaluates the building envelope and equipment as a whole, commending excellent houses that contribute to total energy conservation and CO2 reduction. It aims to contribute to reducing environmental impact through energy conservation and realizing comfortable living spaces.
The [Special Excellence Award] received this time is the second highest award after the Grand Prize, and is given to housing products highly evaluated for their efforts in promoting energy-saving, highly airtight, and highly insulated homes, as well as advancing ZEH (Net Zero Energy House). For our company, this is the fourth time winning the Special Excellence Award in our 12-year award history.
● About the Award-Winning Product 'Gokudan no Ie'
The award-winning product 'Gokudan no Ie' pursues high airtightness and insulation equivalent to Hokkaido standards. It realizes a home that is 'warm in winter and cool in summer', being less affected by severe outdoor temperature environments and preventing comfortable indoor temperatures from escaping. Its insulation performance boasts a high level that also meets the criteria for 'GX-oriented housing', possessing energy-saving performance that greatly exceeds ZEH standards.
By utilizing the latest energy-saving equipment and renewable energy technologies, it reduces energy costs such as utility bills throughout the year and lessens environmental impact. Thanks to the support of many customers, cumulative orders have reached 1,000 houses. It continues to be chosen as Alnet Home's flagship product today.
The environment surrounding homes is becoming increasingly severe year by year, with extreme heat, typhoons, heavy rains, and snowfall. Alnet Home believes that under these circumstances, homes, which are the foundation of living, must possess high-level basic performance of 'insulation' and 'earthquake resistance/vibration control'.
High insulation performance brings year-round comfortable and economical living even in the Kanto region, where temperature differences are becoming extreme, and protects an eco-friendly future through CO2 reduction via energy savings. In addition, high earthquake resistance and vibration control performance provide safe living in preparation for the unlikely event of earthquakes or disasters. 'Gokudan no Ie' was devised to realize a home that is kind to both people and the earth.
Aiming to further popularize high-performance housing, our company will open its second model house in Chiba Prefecture featuring 'Gokudan no Ie' specifications in Matsudo City in January 2026. We will continue to create opportunities for more people to experience its value.

● The Importance of Housing Performance in an Era of Energy Constraints
In recent years, due to tight global energy supply and demand and soaring prices, Japanese housing is required to have higher energy-saving performance than ever before. The role of housing is expanding from merely a 'place to live' to a 'lifestyle infrastructure' that protects residents' health, comfort, and household finances. To meet these social needs, Alnet Home has been quick to work on the popularization of GX-oriented housing, and this proactive stance has been evaluated in this 12th consecutive year of winning the award.
