World's First! Futuristic Residence 'loowell (Ruwel)' Featuring Next-Gen AI-HEMS 'Haiot System' Launches in Niseko

The World’s First AI-HEMS 'Haiot System' Delivers a Futuristic Residence 'loowell Gaku' Comfortable Even at -15°C

WELLNEST R&D Co., Ltd. (Headquarters: Nagoya, Aichi Prefecture; CEO: Hiro Nori Sata) has launched 'loowell (Ruwel)', a next-generation private residence that fuses environmental performance with cutting-edge technology. It is the world’s first residence to implement 'Haiot System (Haiot System)', a next-generation Home Energy Management System (HEMS).

By combining the energy-saving power of a building’s exceptional airtightness and high thermal insulation—overturning conventional residential norms—with the world’s first AI-driven, fully automated energy control system for residences (Haiot System), 'loowell' realizes a future living space where simply living comfortably minimizes environmental impact to the greatest extent possible.

Why 'loowell × Haiot System' is World-First and Revolutionary

[Next-Gen AI-HEMS] Concept of Haiot System’s Full-Automated Control Across the Entire Residence

Currently, residential and commercial buildings account for a significant portion of global energy consumption. Achieving 'carbon neutrality'—balancing greenhouse gas emissions with absorption—requires urgent energy-saving measures in housing. However, conventional smart homes and HEMS have been limited to 'data visualization' and 'manual device operation', falling short of true optimization.

The 'Haiot System' implemented by loowell for the first time in the world is a [Next-Gen AI-HEMS] that uses AI to monitor and autonomously control residential energy and indoor environments 24/7 in real time. Without requiring occupants to endure discomfort or manually operate switches, the system automatically creates the most eco-friendly and comfortable conditions.

Three Innovations Brought by 'Haiot System'

① Fully Autonomous Control by AI (No-Touch Life)

AI integrates and controls solar power generation, battery storage, HVAC (heating and cooling), and ventilation systems. By anticipating residents’ lifestyles, next-day weather forecasts, and climate changes, it autonomously maintains optimal energy distribution at all times.

② Maximizing Self-Consumption of Energy

Excess electricity, which previously could only be sold back to the grid, is efficiently redirected by AI to battery storage or Eco Cute (hot water systems), achieving a high level of 'local production for local consumption' and complete energy self-sufficiency.

③ Smart Integration Beyond Manufacturer Boundaries

Even appliances and equipment from different manufacturers are centrally managed within the Haiot System, dramatically reducing the building’s overall power consumption.

Architectural Achievement: WELLNEST HOME’s 'Ultimate Enclosure' Supporting the World’s First Brain

No matter how advanced the AI (Haiot System) is, if the building itself leaks heat—like water from a bucket with holes—it defeats the purpose.

loowell adopts the exceptional construction technology of WELLNEST HOME Co., Ltd., a pioneer in airtight, high-insulation homes, including its double insulation method (cellulose fiber filling, fire-resistant rock wool).

It is precisely because of this 'thermos bottle'-like, exceptional building performance that the full potential of the Haiot System can be maximized. Even during harsh winters with outside temperatures below -15°C, a single air conditioner maintains uniform temperature and humidity throughout the interior. Residents can stand by the window in just a T-shirt and feel comfortable—an ultimate combination of energy efficiency and supreme comfort.

First Implementation: Launching at 'loowell Gaku' in Niseko, Hokkaido

Exterior Concept of 'loowell Gaku', the World’s First Residence to Introduce [Next-Gen AI-HEMS] Haiot System

As the proving ground and embodiment of this world-first 'Haiot System × ultra-high-performance architectural residence', the advanced district 'Niseko Mirai' in Niseko, Hokkaido—a world-class snow resort where massive winter energy consumption has been a challenge—has been selected. Membership recruitment for the next-generation private residence 'loowell Gaku' has now begun.

The 'three barriers' of villa ownership—high cost, environmental burden, and management—are being eliminated through a shared ownership model starting at ¥12.1 million per share, district-linked management, and the combination of high-performance structure with the world’s first Haiot System. Even when owners are absent, the Haiot System remotely maintains the indoor environment in optimal condition, welcoming them with the best possible experience upon arrival.
