两座新城，让绿色可知可感（美丽中国·关注零碳园区）

Core Viewpoint - Shaanxi Xixian New Area's Konggang New City and Fengxi New City have been selected as the first batch of low-carbon and near-zero carbon county (district) and park pilots in Shaanxi Province, focusing on green low-carbon development and carbon emission reduction in production and operation processes [1][2]. Group 1: Low-Carbon Development Initiatives - The two new cities are promoting low-carbon and near-zero carbon park construction through energy transition, building energy efficiency, transportation optimization, and industrial upgrading [2][3]. - The Xi'an Xianyang International Airport T5 terminal, which opened in February, incorporates various green design elements and has been recognized for four low-carbon cases at a national conference [2][3]. Group 2: Renewable Energy and Technology Integration - The China Western Science and Technology Innovation Port's Yuanju Building integrates seven energy-saving and emission-reduction technologies, achieving self-sufficiency in daily office electricity through solar photovoltaic walls [3]. - The building's smart green energy system covers an area of 2,750 square meters, generating approximately 400,000 kilowatt-hours annually [3]. Group 3: Clean Heating Solutions - Fengxi New City is implementing a clean heating technology that utilizes deep geothermal energy to address high carbon emissions during winter heating [4]. - This technology involves drilling 2,000 to 3,000 meters underground to extract heat using a closed metal casing heat exchanger [4]. Group 4: Digital Transformation and Energy Management - Konggang New City leverages its unique resources, including the Xi'an Xianyang International Airport, to develop advanced manufacturing, aviation support, and high-end services [5]. - A digital transformation office has been established to promote low-carbon aviation and explore smart airport solutions using Building Information Modeling (BIM) for construction management [5][6]. Group 5: Research and Development Focus - The construction of zero-carbon parks relies heavily on continuous technological innovation, with a need for increased R&D investment in clean energy, energy efficiency, and carbon capture technologies [7]. - A collaborative research center for carbon neutrality is being established to accelerate the implementation of low-carbon technologies through partnerships between universities and enterprises [7].
