Kankyokenchiku/Environmental initiatives including ZEB
"Joy and health together" for the next architectural challenge
Mitsubishi Jisho Design advocates "architecture that contributes to the promotion of health management and realizes a healthy environment = Kankyo Kenchiku" (welcoming and healthy building), and offers high-value-added proposals that combine consideration for the global environment with comfort, health promotion, and improved productivity.

Initiatives towards ZEB
In addition to improving energy efficiency for ZEB, we are also introducing various environmentally friendly technologies to large-scale buildings, aiming to create a highly comfortable work environment that focuses on diverse work styles and worker preferences. These technologies are introduced through a new system development, experimental phase, and demonstration phase in small and medium-sized buildings, and we are working on designing buildings with next-generation energy efficiency and comfort based on simulations and actual measurements.
ZEB Planner
Our company is registered and publicly announced as a "ZEB planner." Utilizing the technology and knowledge we have cultivated for designing ZEB and energy-efficient buildings, we provide design and consulting services for the realization of ZEB, proposing optimal solutions that not only meet the SDGs but also take into account costs and comfort.
ZEB Goals
By fiscal year 2030, for design and consulting projects that our company undertakes, we aim for a 50% ZEB (Zero Energy Building) penetration rate for new buildings under 10,000 m² and 100% for buildings of 10,000 m² or more. For existing buildings, we aim for a 20% increase in ZEB conversion compared to the previous year.
*Excluding orders that do not contribute to the realization of ZEB (Zero Energy Building) buildings.
