钻孔换热器（BHE）阵列代表了未来提供可持续建筑供暖和制冷能源的关键技术。它们要么用作纯地热系统，仅从地下提取热能，要么也用于储存太阳能集热器的余热或夏季冷却应用的废热。系统的多样性使得很难确定在减排和经济效率方面的最佳系统。在这项研究中，我们评估最相关的BHE系统布局的加热，以及结合使用动态模拟的整体加热系统的环境经济分析方法相结合的加热和冷却的目的。该评估程序用于多目标优化方法，以最小化不同系统布局的排放因子（EF）和水平化能源成本（LCOE）。为了科普所需的长期考虑的高计算成本，人工神经网络（ANN）已被用来生成一个代理模型的多目标优化过程的中间步骤。这种方法提供了可靠的优化结果，结果表明，太阳能辅助布局实现了加热和冷却系统的最低排放。与基于化石燃料的参考布局的比较表明，最经济的BHE布局实现了EF减少60%，LCOE仅增加13%。然而，如果考虑到排放惩罚成本，与化石燃料系统相比，评估的布局也具有经济优势。
Borehole heat exchanger (BHE) arrays represent a key technology for the future provision of sustainable building heating and cooling energy. They are either used as pure geothermal systems only extracting heating energy from the subsurface or they are also used to store excess heat from solar thermal collectors or waste heat from cooling applications in summer. The diversity of the systems makes it difficult to identify the optimal system in terms of emission reduction and economic efficiency. In this study, we assess the most relevant BHE system layouts for heating-only as well as combined heating and cooling purposes using dynamic simulations of the overall heating system in combination with an enviro-economic analysis method. The assessment routine is used in a multi-objective optimization approach to minimize the different system layouts' emission factor (EF) and their levelized cost of energy (LCOE). In order to cope with the high computational cost of the required long-term considerations, an artificial neural network (ANN) has been used to generate a proxy model in an intermediate step of the multi-objective optimization procedure. This approach delivers reliable optimization results, which reveal, that the lowest emissions for heating and cooling systems are realized by solar-assisted layouts. Comparison with a fossil-based reference layout shows that the most economical BHE layout accomplishes a 60% reduction in the EF with a moderate increase in the LCOE of only 13%. If, however, emission penalty costs are taken into account, the evaluated layouts also become economically advantageous compared to fossil-based systems.
