Heating sources to be evaluated include, but are not limited to, natural gas, all electric, radiant floor system, or combination of these. If natural gas is provided at the facility, carbon monoxide detectors

2 Amendment 4 shall be provided in each occupied space. in accordance with the protected premises carbon monoxide detection system requirements of NFPA 720. Final design shall include a comparison of three or more systems based on the region, building design features and available energy sources. Heating hot water systems can be evaluated as one of the LCCA alternatives to compare constant speed distribution pumping and variable speed distribution pumping systems. The final design shall include a short (a few pages describing results, methods, reason for selection and why, etc.) summary report and Building Life Cycle Cost (BLCC) program output and input. The contractor shall utilize either TRANE Trace version 700 or Carrier Hourly Analysis Program (HAP), latest editions to provide system energy consumptions. Provide reasonably detailed cost estimates for each systems studied as part of the design analysis. This will be the heating system that is being proposed for the facility. The life cycle analysis shall be performed and documented by utilizing the free computer program, BLCC that is available via the US Dept of Energy web sites. The programs reports will document all input and output. The actual site utility costs at the installation shall be input into the BLCC program for the LCC equipment selection. Refer to the RFP Appendices for the current site specific utility rates. The life cycle cost analysis shall run for a minimum of 25 years and shall include any final salvage values and annual costs for operation and maintenance based upon ASHRAE estimation methods for those costs. Salvage costs shall be documented in cost estimates and should generally be restricted to larger equipment items such as boilers, pumps, and large air handlers, for example.
