Basic Scientific Issues of Zero-Carbon Buildings in the Solar Energy Enrichment Area
The implementation and promotion of zero carbon buildings is of great significance to achieve the goal of carbon neutrality."The solar energy enrichment area"refers to the area with total annual horizontal irradiation of over 6300 MJ·m-2·a-1,as defined in the"Assessment Method for Solar Energy Resource"GB/T 37526-2019.The solar energy enrichment areas are mainly distributed on the Qinghai-Tibet Plateau,with extremely special geographical characteristics:cold winters,long heating periods and high carbon emissions during the operational stage;intense radiation,large annual and daily temperature range,poor operation stability and low efficiency of building equipment system;scarce conventional energy resources,but abundant solar radiation resources,which reduces the cost of large-scale utilisation of solar energy,and has the endowment conditions to take the lead in realising the goal of carbon neutrality for buildings on a regional basis.Under the overall layout of the dual-carbon strategic goals and tasks of the nation and the construction industry,the"Key Technology Research and Demonstration of Zero-Carbon Buildings in Solar Energy Enrichment Areas"has been supported by the National Key Research and Development Program of the 14th Five-Year Plan.The project aims to achieve the first demonstration of regional zero-carbon buildings by exploring suitable technical pathway,design method and technical support system for zero carbon buildings using solar energy as the driving energy source and combining the architectural characteristics and socio-economic development level.The purpose of this paper is to put forward several suggestions on the basic scientific issues of zero-carbon building research in solar energy enrichment areas,and provide a theoretical basis for the key technology development and engineering demonstration.
