Green properties
We are determined to give back to the society and change the world for the better with buildings. We are concerned about environmental protection, people’s livelihood and economic development in communities where we operate. We leverage our advantages in business, technology and resources to manage and reduce operations impacts on the environment and society with the aid of various community investment projects, so as to contribute to a long-term and healthy development.
Green Building Certification
Among the projects completed in 2018, COLI obtained 44 green building certifications (42 for residential projects and 2 for commercial projects), including 31 one-star certifications, 10 two-star certifications, 1 three-star certification, and 2 LEED Gold Awards, covering a total gross floor area (GFA) of 8.79 sq m. As at the end of 2018, COLI had developed a total of 154 green building-certified projects (134 residential projects and 20 commercial projects), with a total GFA of 28.4 million sq m.
Green Construction
COLI has developed specifications on how to use and manage building materials to improve the efficiency of resource use. The Company’s Green Building Technical Manual, prepared based on the latest national standard – Green Building Assessment Standard, provides economically and technically optimal options for reference and use by our teams according to the green building certification requirements at different star levels. We recommend that new projects use not less than 8% of reusable and recyclable building materials and pursue 100% integration of civil engineering and decoration design.
Chemicals at construction sites are stored in areas with waterproof layer and impervious concrete to prevent land pollution caused by leakage of chemicals. Each construction site has in place at least three garbage pools to collect and store hazardous wastes, recyclable materials and other wastes separately. The hazardous wastes must be stored separately in designated sealed containers and marked. The project team has to entrust a transportation agency approved by the environmental protection bureau to transport toxic and hazardous wastes to the designated place for dumping and make disposal records.
Green Operation
This year, a building energy management system developed by the Company was officially put into operation and applied to 10 projects of COCP. We installed a total of 8,593 metering stations to monitor the energy consumption and power distribution of each equipment and facility in real time, and analyzed the monthly energy consumption and energy saving results of each project in operation. As there are many kinds of electromechanical equipment, we have developed an energy consumption model using a unified data definition method to carry out energy management based on classification of monitoring data. The Company also put in place dedicated energy management personnel, who are responsible for using the platform for energy saving diagnosis, recording abnormal energy usage, and submitting monthly operational energy consumption analysis and energy conservation reports for discussion of energy-saving measures.
We organize the property management office of each project to inspect its water supply network and facilities on a daily basis, conduct leak detection at least once a year, and intensify examination of water-consuming facilities such as swimming pools and waterscape pools to deal with water leakage and overflow in a timely manner. We also require the property management office to read the main water meter every day for water consumption measurement and analysis, formulate relevant water-saving measures accordingly, and carry out publicity of water conservation among customers once a year. This year, we also carried out water-saving renovation works in several hotel projects, including the installation of additional equipment in The Coli Hotel, Shenzhen, to recycle steam condensate, and the replacement of the obsolete water supply network of Shantou Nanbin Hotel to reduce the chance of blasting and leakage of pipes.
