CH-15-026 -- First Experience in Extending the Reach of an Energy Concept through an Advanced ESPC Model ✓ Most Recent

Many governments worldwide are setting more stringent targets for reductions in energy use in government/public buildings. The U.S. government has targeted annual energy savings of 3% (DOECC 2013). The European Union (EU) will have to refurbish from 1% to at least 3% of its building stock to meet its ambitious efficiency targets. This paper describes a small municipality that took advantage of an energy savings performance contract (ESPC) business model to refurbish a campus with school and administrative buildings and a swimming pool. The ESPC project presented here proves that the technical scope of ESPCs can be extended according to the customer’s demand, from the typicalHVACand control system to more challenging measures like a biomass heating plant and a microheating grid and ambitious non-energy-related refurbishment measures like a swimming pool basin or other construction improvements.

urthermore, it shows that guaranteed significant energy and cost savings were largely achieved, and that the predicted investment costs were not exceeded. The guaranteed savings achieved in the project were successfully used to pay off the energy conservation measures (ECMs) and to partly fund the investment in deep refurbishment. The paper highlights the structures that were predicted to enhance coordination between stakeholders and presents an engineering analysis of the design process required to develop and implement the project. The paper also describes how careful project preparation minimized risk and eased the coordination between planners and contractors so the project could reach completion within the projected schedule. Finally, this paper provides specific lessons learned and recommendations for other similar projects.
