■ Main Initiatives and Evaluation Points for Health Management
【Initiatives】
Our company is undertaking the following initiatives to promote the physical and mental health of our employees.
① Employee health interviews and health checks (2-3 times a year)
② Online health room (in partnership with external public health nurses)
③ Health seminars (monthly online)
④ Public health nurse newsletter (monthly)
⑤ Health information email magazine (weekly)
⑥ Health improvement award ceremony (Health Improvement Award)
⑦ Walking rally
【Evaluation Points】
The walking rally achieved 100% participation, implemented as a company-wide initiative. The introduction of award ceremonies and team competitions also led to the revitalization of internal communication. As a result, the percentage of employees who "do not have exercise habits" improved from 65% to 45%, and regular exercise habits are becoming established. In addition, the percentage of employees who are "conscious about their diet" increased from 30% to 55%, confirming that each employee's health awareness is increasing. Furthermore, 85% of employees "feel passionate about their work," indicating high engagement.
Our company will continue to strive for the physical and mental health of our employees and create a comfortable working environment, aiming for increased organizational vitality and further growth.
■ About the Environmental and Energy Saving Calculation Center
Our center supports energy-saving calculations and environmental performance certification (BELS, ZEB, ZEH, CASBEE) for all types of buildings, whether new or existing, including residential (detached houses, condominiums), office buildings, commercial facilities, hotels, warehouses, nursing homes, and schools. We also provide consulting services, such as what renovations are necessary when building renovations are carried out to obtain certification.
Our client base includes architectural design firms, developers, general contractors, real estate funds, and J-REITs. In particular, since the full enforcement of the revised Building Energy Conservation Act, our order performance has steadily increased, achieving approximately 1,800 buildings annually, 1.8 times the previous year.
【Our Center's Strengths】
Strength 1: Applicable to both new and existing buildings
Generally, energy-saving calculations for existing buildings are said to be more difficult due to the frequent lack of complete drawings and equipment information. Our center has experienced staff who can smoothly handle both new and existing buildings.
Strength 2: Capable of handling multiple tasks consistently
We handle energy-saving calculation related tasks consistently, starting from hearing requests. This unifies tasks that would normally require interaction with multiple companies, reducing the burden on customers and shortening work time.
Strength 3: Knowledge of the financial industry
Representative Director Keisuke Onoshi is well-versed not only in the real estate industry but also in the financial industry, enabling him to support environmental performance certification from a fund perspective. In addition, we also provide some consultation regarding subsidies that can be utilized for certification acquisition.
