01 Eco-friendly building with a minimal burden

We promote Eco-tuning, a way to solve problems. "Eco-tuning" means overall improvement in operation to reduce greenhouse gas emissions aiming at low-carbon society. We conduct detailed analysis of energy consumption and propose solutions with minimal investment.



We charge a certain percent of reduced utilities (power, gas, water, etc.) cost, so there is no additional cost for clients. If there is no reduction, there is no charge.


Eco-tuning is a registered trademark of Ministry of the Environment. Our company was registered as a certified operator in March 2017. We search for optimum operation of equipment and systems while securing comfortable and productive environment.

03 Centralized management of multiple buildings' equipment data

If multiple buildings are managed by different management companies and data are not centrally managed, owners may have difficulties in developing appropriate business plans, performing efficient management, or making quick decisions. We have LEAD-Web system for such concerns.
With this system, owners can efficiently centralize the management of data such as repair history, building assets, drawings, contractors, as well as basic building ledger, documents and photos.

We can keep updating the data if LEAD-Web is packaged with our periodic building diagnostic service. Owners can grasp status quo of their buildings in real time.

04 Support residents

We provide useful information to condominium residents. Increasing their level of satisfaction also increases the asset value. However, it may be difficult to provide information to a large number of residents promptly and at an appropriate timing. In such cases, we suggest our clients to use our application.

Lifenote mobile is an application to support the condominium residents' living. We provide useful information for elderly people and dual-income families to improve every-day life quality and to support creating a community by serving as a bulletin board.
We also help residents optimize their contracts for electricity.
