Subway Tunnel Energy Study

摘要

The idea of the Subway Tunnel Energy System was conceived by Joel Levinson of Levinson Zaprauskis Associates (LZA), and proposed to the City of Philadelphia in 1981. LZA believed that a study of the feasibility of using subway tunnel air as a heat sink/heat source to reduce the costs of heating and cooling buildings adjacent to the tunnel might also prove beneficial. Cities including Philadelphia might be able to generate revenues from the sale of the tunnel air to building owners or offer free access to the tunnel air as an incentive to real estate developers who might otherwise choose to build elsewhere. This might also reduce energy consumption in the long term by increasing the use of in-place mass transit systems. After investigating various directions during Phase 2, LZA concluded that the STES would not prove cost effective in the economic energy climate of today. The report outlines the research results of the STES Study and provides a task by task description of the research process followed by LZA and its consultants through to the point of termination.
