■ Background and Objectives
In recent years, the new housing market has been facing demands to adapt to higher environmental performance and decarbonization, such as the introduction of GX-ZEH standards and the mandatory compliance with energy-saving regulations. Furthermore, as the lifestyles of residents change, the equipment and services required for homes (solar power generation, home telecommunications, smart locks, etc.) are becoming increasingly diverse and complex.
Under these circumstances, housing businesses face the urgent task of differentiating their properties from competitors and improving added value. However, the increased burden of sales resources and the effort required to arrange and manage diverse services individually has become a major challenge.
To solve these issues, Osaka Gas Marketing utilized the extensive expertise and long-standing operational track record of the Daigas Group to launch 'Sumai Selection,' which integrates various optimal services for homes. Through this brand, we propose one-stop added value to housing businesses nationwide, contributing to the enhancement of their business value and the realization of a rich and advanced lifestyle for the residents.
■ Details and Features of 'Sumai Selection'
'Sumai Selection' is a solution package that provides the safe and comfortable living environment universally sought by customers in home building, sustainable economic efficiency, and advancement looking toward future lifestyles. It also meets the demands of 'environmental performance' (decarbonization, ZEH compliance, etc.) adapting to changing times.
By adopting 'Sumai Selection,' housing businesses can consolidate these multiple service procurement contacts into Osaka Gas Marketing, significantly reducing the time and effort required for proposals and arrangements. At the same time, it allows them to improve the added value of their properties.
■ Future Outlook
Moving forward, through direct proposal activities to housing businesses nationwide, we aim to expand brand recognition and establish a nationwide business foundation.
Osaka Gas Marketing, together with Daigas Group companies and various partners, will pursue what is needed and desired for living from the customer's perspective, supporting a future filled with smiles.
