Designing: Environment-conscious initiatives
Utilizing CO2 Emissions Calculation Sheet
In April 2017, we revised Haseko Corporation’s proprietary “CO2 Emissions Calculation Program,” which we had continued to operate since its development in 2011. Based on the revision, we began calculating the CO2 reduction rate based on the “CO2 Emissions Calculation Sheet” using the figures calculated in accordance with the Act on the Improvement of Energy Consumption Performance of Buildings. We have been implementing the revised program since then.
In fiscal 2018, we set CO2 reduction rate of 10% or higher (compared to the standard value under the Act on the Improvement of Energy Consumption Performance of Buildings scheduled to become mandatory in 2020) as our numerical target and implemented it in 117 projects of condominiums designed between April 2018 and March 2019 (90 projects in the Tokyo region and 27 projects in the Kansai region).
|Tokyo region||Kansai region|
|CO2 reduction volume (FY2018)||5,399ｔ-CO2/year||1,471ｔ-CO2/year|
|Standard value under Act on the
Improvement of Energy Consumption Performance
|CO2 reduction rate||(11.6%)||(11.3%)|
* The CO2 Emissions Calculation Sheet is a sheet for computing the CO2 reduction rate by converting the standard value and the design value of primary energy consumption of condominium unit areas and communal areas calculated with respect to each project using a Web program in accordance with the Act on the Improvement of Energy Consumption Performance of Buildings into CO2 emissions (t-CO2/year).
Promotion of wood use in construction of condominiums
Efforts to promote wood use in construction have been made by the Ministry of Agriculture, Forestry and Fisheries (the Forestry Agency) and other organizations.
We set up the Working Group for Wood Utilization with the purpose of examining the feasibility of wood use in our condominiums and prioritizing technologies we should explore. Its studies are currently under way.
At “Kita-ku Oji 5-chome Project,” which was completed in the spring of 2018, we have installed a wooden party room in the communal area that connects rental condominium “BRANSIESTA Oji” and paid care house for the elderly “Century City Oji.” Positive impacts such as reduced environmental burden can be expected. Going forward, we will pursue research and verification activities so as to solve social issues and deliver to our customers the warm and comforting appeal of wood.

Wooden pavilion "URO-CO"
Haseko Corporation’s Engineering Dept., whose sponsorship of Kengo Kuma Laboratory at The University of Tokyo dates back to 2011, has been conducting joint research with The University of Tokyo’s Kuma-LAB since February 2018. This research is conducted to pursue the possibilities of designs leveraging the special characteristics of wood as a material and explore the possibilities of cutting-edge construction technology and design using computers through research on morphological control, etc. Most recently, "URO-CO," a pavilion utilizing design techniques and processing technologies derived from this research, has been completed. Going forward, we will consider expanding this into actual projects as a wood processing technology.
