Economics of cogeneration in commercial buildings

OSTI ID:6473822
A method of analyzing the economic feasibility of utility interconnected cogeneration facilities in commercial buildings is presented. Some general rules of thumb for the designers of these systems and a detailed understanding of the complex interactions between variables such as building type, cogeneration plant size, thermal loads, electric loads, and electric rate structures are given. A modified version of the DOE-2 Building Energy Analysis Model was employed to simulate the energy flows within the apartment and office buildings studied. The cogeneration technology simulated in all cases was a generic type, consisting of medium-speed diesel-generator sets with heat recovery from exhaust, jacket water, and lubricating oil. For each building type five system sizes were evaluated and Appendix A gives the installed cogeneration capacity and other plant parameters for all 10 cases. Different rate types (declining block rate, time of day, etc.) were used in the analysis so that any economic perturbations due to rate type would be observed; actual rates used appear in Appendix B. Cost assumption data appear in Appendix C. (MCW)
