(Headquarters: Chiyoda-ku, Tokyo; Representative Director, President, and CEO: Hideo Tanaka) that promotes the income property business, has acquired the CASBEE Real Estate Assessment Certification "A Rank" for the renovated apartment complex "U residence Mukogawa." In addition, the commercial building "Namba Midosuji West," which also underwent renovation work, acquired a "★★★" (3 stars out of a 0-6 scale) rating under the "Building Energy-efficiency Labeling System (BELS)." Furthermore, the apartment complex "U residence Shimokitazawa" developed by our company also acquired a BELS "★★★" (3 stars out of a 0-4 scale) rating.
Going forward, we will continue to clearly indicate the environmental performance of the buildings we offer, tackle social issues through businesses that meet environmental needs, and promote businesses aimed at realizing a sustainable society.
1. What is CASBEE?
CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is a system that comprehensively evaluates building quality, including environmental considerations such as energy conservation and the use of materials with low environmental impact, indoor comfort, and consideration for the landscape. CASBEE has different classifications depending on the evaluation target, such as Buildings, Detached Houses, Real Estate, Wellness Offices, and Urban Development, and sets five evaluation ranks (S, A, B+, B-, C) according to the assessment level.
2. What is BELS?
BELS (Building Energy-efficiency Labeling System) is a third-party evaluation system for the energy consumption performance of buildings. BELS indicates the energy reduction rate against the energy conservation standards set by the government using a star rating. For evaluations of houses without renewable energy equipment, there is a 5-level evaluation scale (0 to 4 stars), and for houses with renewable energy equipment and non-residential buildings (regardless of the presence of renewable energy equipment), there is a 7-level evaluation scale (0 to 6 stars).
3. Securing sufficient environmental performance through appropriate renovation and management even for buildings around 30 years old
ADW has been actively continuing its efforts to acquire environmental certifications for properties it renovates and develops.
This time, "U residence Mukogawa" acquired the CASBEE Real Estate Assessment A Rank by visualizing operational realities such as waste disposal and incorporating landscaping centered on native species, in addition to excellent track records in energy and water usage. Furthermore, "Namba Midosuji West" acquired a BELS "★★★" (3 stars) by reducing energy consumption from its previous level by changing lighting to LEDs during renovation. Although both buildings are over 25 years old, they were able to receive sufficient evaluation through renovations and appropriate property management.
In addition, "U residence Shimokitazawa" is an apartment complex developed by our company, and it was developed by creating a plan that ensures a certain level of energy performance from the design stage.
Going forward, we will continue to strive to provide high-quality income properties with high user demand while addressing environmental issues by applying value-ups in line with environmental needs to real estate owned and developed by our group, acquiring environmental certifications, and conducting safe and secure renovation work.
