Information in this report is arranged to provide a sequential review of the major steps that a city or county should undertake when evaluating the merits of renovating an older steam-based district heating system. Chapter I provides a general overview of district heating systems, and discusses some of the major systems components, requirements and advantages. The section focuses specifically an older steam based systems operating in US cities, and includes a brief history of the development and evolution of these systems, as well as a discussion of some of their problems. A brief description is also provided of state and federal research directed at assisting cities to bring about improvements to these systems. Chapter II outlines procedures for evaluating both the economic and energy efficiency merits of measures designed to renovate old steam-based district heating systems. This chapter presents a six-phased process for identifying, reviewing and evaluating options which could bridge the gap between the real potential for district heating as a preferred energy supply systems for cities and the real problems of existing steam-based system. Chapter III describes the application of the procedure developed in Chapter II to two steam-based district heating systems in San Francisco. These systems provide ''textbook'' examples of the district heating systems in need of major rehabilitation. Chapter IV concludes with a discussion on lessons learned from the San Francisco case study. Procedures and research methods that were used throughout the project are evaluated for both their overall effectiveness and transferability to other countries. In addition, this chapter suggests methods for adapting San Francisco's project results to the needs of other countries. 11 refs., 8 figs., 13 tabs.
