A similar situation exists at the CPP subsystem level and in the delivery aspect of the CPP system mandate, involving tunnels and alternate flow paths. CPP Option 1 is an extension of the existing CPP using various fuel options.

The steam and chiller probability models can be combined with the relevant CPP demand models to produce responsive plant reliability indices. These indices can also be used to assess the reliability implications associated with increased or uncertain load demands and the reliability effects of decreased load demands due to building efficiency or technology improvements.

This will allow the consideration of successful technologies as the Strategic Long Term Energy Plan is periodically brought up to date. These technologies include, but are not limited to: • Novel fuel mix strategies; • Feasible alternative or renewable fuel options; • Heat recovery in the supply and use of energy; • Improved heat balance through the use of auxiliary drives; • Limiting supply of steam in the summer and satisfying small heating loads through other methods; • Use of superheated steam rather than saturated steam; • Chilled-water storage systems; • Metering technologies for all major plant equipment and energy destinations; • Fully integrated digital controls; • Real-time modeling of plant operations, chilled water and steam hydraulics, and environmental effects; • State-of-the-art tunnel construction methods; • Geothermal heating and cooling; and • Use of solar panels on building roofs and the grounds of the U.S.

If feasible, the benchmarking of the AOC facilities should be augmented by collecting comparable data from other district energy systems, including those of the General Services Administration and the Washington Navy Y ard, and collecting and implementing best-in-class practices. RESPONSE TO SHORTCOMINGS IDENTIFIED As a general catchall category, the committee recommends that the AOC review the shortcomings identified in Chapter 2 that have not been explicitly addressed as recommendations for additional work, and develop an action plan to address those shortcomings it considers material.
