Geothermal energy is a collective term referring to Earth heat extraction and use of the ground capacity to absorb and store thermal energy to supply heat or cold. Thermal ground exchange or shallow geothermal energy has been increasingly used in the housing sector to sustain comfortable room temperature. Increasing utilization of geothermal energy, particularly in urban areas, requires integration into urban planning processes. The question of subsurface planning, or underground space integration into land-use planning, or three-dimensional planning has been an emerging research theme in this decade. This paper will focus on specific issues that pertain to geothermal energy use in land use planning in urban areas. These issues include (1) holistic vision of underground space as a resource, (2) geothermal energy technologies in terms of using space, (3) multiple users and installations of heat pumps and their interaction, (4) possible conflicts and interference with other subsurface users and functions, (5) demand and suitability of geothermal use in housing, (6) urban densities and geothermal energy feasible use, (7) and general principles of urban geothermal land use planning. A feasibility case study of using heat pumps to provide heating for a typical historic residential multifamily building in the Petrogradsky district of the city of St. Petersburg, Russia is given.

地热能是一个统称，指的是地球热量的提取和利用地面容量来吸收和储存热能以提供热量或冷量。地热交换或浅层地热能已越来越多地用于住房部门以维持舒适的室温。增加地热能的利用，特别是在城市地区，需要整合到城市规划过程中。地下规划问题，或地下空间与土地利用规划的整合，或三维规划，一直是这十年中新兴的研究主题。本文将重点关注与城市地区土地利用规划中地热能利用相关的具体问题。这些问题包括 (1) 将地下空间作为一种资源的整体愿景，(2) 使用空间方面的地热能技术，(3) 热泵的多用户和安装及其相互作用，(4) 与其他地下用户和功能的可能冲突和干扰，(5) 地热利用的需求和适用性住房，（6）城市密度和地热能源的可行利用，（7）城市地热土地利用规划的一般原则。给出了使用热泵为俄罗斯圣彼得堡市彼得格勒区典型的历史悠久的多户住宅供暖的可行性案例研究。(6) 城市密度和地热能的可行利用， (7) 城市地热土地利用规划的一般原则。给出了使用热泵为俄罗斯圣彼得堡市彼得格勒区典型的历史悠久的多户住宅供暖的可行性案例研究。(6) 城市密度和地热能的可行利用， (7) 城市地热土地利用规划的一般原则。给出了使用热泵为俄罗斯圣彼得堡市彼得格勒区典型的历史悠久的多户住宅供暖的可行性案例研究。
