To create a low-carbon society, Kume Sekkei has developed the latest architectural and environmental design that realizes a healthy and comfortable environment with reduced energy consumption, at the same time providing priority to achieving safe architecture systems.
Through the measures to deal with environmental issues (shift to low carbon), Kume Sekkei has planned, designed and realized numerous eco-friendly systems and high-efficiency facility systems, from the basic to the most cutting edge.
We start eco-friendly architectural design by carefully analyzing the local natural environment and the traditional and vernacular architecture that has been cultivated over many years.
With architectural techniques for reducing the loads and benifiting from nature, while at the same time adopting high-efficiency facility systems, we create a comfortable environment in a rational and economic way.
By minimizing the heat that enters the building, the capacity of facility equipment for processing the heat load can be reduced. Architectural techniques such as eaves, louvers, and underground burial are studied to plan and propose buildings with reduced operation energy and costs (LCC and LCCO2).
After clarifying the regional features, elements such as the light (natural light, solar power generation), wind (natural ventilation, outdoor air cooling, night purge), water (use of rainwater and groundwater), soil (earth tubes, geothermal heat), and green elements (roof afforestation, wall surface afforestation) are selected as appropriate, to plan and propose architecture with a minimal heat load.
We design heat source and air-conditioning systems that eliminate waste and conserve energy, and develop a comfortable heat environment, a high air quality environment, and excellent light and vision. We also deploy systems to enhance building operation and management efficiency, in appropriate and low-cost ways.
Enterprises and organizations are today expected to conduct low-carbon activities, as exemplified by the amendment to Energy Conservation Act.
Kume Sekkei has placed special emphasis on low-carbon solutions from the perspective of LCC and economic feasibility, and has provided low-carbon consulting, mainly at the Environmental Planning Center.
We strive to extend the service life (for instance, by emphasizing durability, ease of renewal, conversion, etc.), while also supporting the shift to low-carbon building through radical cuts to operating costs. For these purposes we use software developed in-house called “KUME ECO PACK50” for LCC and economic feasibility, aiming to reduce operation energy (CO2 emissions) by 50%.
Proposals for improving operation (commissioning) are made through an analysis of operation records, to support shifting to low-carbon building. Effective proposals are made promptly through our own simplified CO2 reduction forecasting simulation software “e-test”.
