- Sino Energy Conservation International Limited, formerly known as CHYY Development Group Limited and China Ground Source Energy Industry Group Limited, is an investment holding company specializing in the research, development, promotion, and application of shallow geothermal energy systems and building energy conservation solutions. Incorporated in 2000 and headquartered in Hong Kong, the company operates primarily across the People's Republic of China, with technological and industrial operations anchored by its core subsidiary, Ever Source Science and Technology Development Group Co., Ltd. in Beijing. The company operates through four principal business segments: Shallow Geothermal Energy, Air Conditioning and Shallow Geothermal Heat Pump, Property Investment and Development, and Securities Investment and Trading. The company offers a comprehensive range of clean energy and environmental building technologies centered on its proprietary HYY single-well circulation heat exchange collection technology. In its Shallow Geothermal Energy segment, the company provides end-to-end energy system solutions, including geological surveys and project feasibility planning; engineering, procurement, and construction (EPC) of shallow geothermal heating and cooling networks; well sinking and specialized borehole drilling; distributed and centralized energy station engineering; smart energy monitoring and system commissioning; and ongoing facility operation, repair, and technical maintenance services for residential, commercial, municipal, and industrial properties. Through its Air Conditioning and Shallow Geothermal Heat Pump segment, the company manufactures, trades, and distributes energy-efficient environmental systems, including shallow ground-source heat pump units, water-source heat pump equipment, geothermal central air conditioning systems, terminal fan coil units, heat exchange devices, and related HVAC automation hardware. Its Property Investment and Development segment engages in commercial and industrial property leasing and real estate development to generate recurring rental income, while its Securities Investment and Trading segment manages treasury assets, listed equity investments, and financial instruments. In recent developments, the company officially changed its name from CHYY Development Group Limited to Sino Energy Conservation International Limited in July 2026 to reflect its broader strategic alignment with clean energy conservation, decarbonization initiatives, and national sustainable development goals. In September 2026, the company completed a major capital reorganization involving a 10-to-1 share consolidation and capital reduction, establishing the temporary trading counter HKEX:8573 on the Hong Kong Stock Exchange to support market trading alongside its primary listing code HKEX:8128. Operationally, the group continues to expand its shallow geothermal energy footprint across northern and central China, advancing standardized green heating contracts, municipal clean energy infrastructure partnerships, and smart building retrofit programs under state-level carbon neutrality frameworks.
