  1. 1. EnRiMa DSSFunctionalities E. Perea, A. Mera, M. Fernández, A. Eguzki eugenio.perea@tecnalia.com 27. February 2014
  2. 2. Introduction 2 • Building Facility Manager • Investments decisions • Energy systems operations • EnRiMa DSS and its functionalities – Friendly interface. – Risk Management. – Support to strategic investment decisions. – Support to operational decisions. – Some tests in KUBIK laboratory building: • Thermodynamic models calibrations • Energy savings potential • Conclusions
  3. 3. 3 Building Facility Manager • Person in charge of the Building Facilities management: energy infrastructures and other services like the cleaning or furniture accommodation. – In charge of the energy bill and energy infrastructures investment. – In charge of the correct and efficient operation and use of the energy infrastructures of the building.
  4. 4. 4 Investments decisions • Should I: – Replace the boilers? – Install renewables? – Self consume the energy generated by the CHP units or photovoltaics? – Renew the lighting installation? – Refurbish the facades? • What technology is the most profitable instead the old boilers? CHPs with thermal solar panels, heat pumps…? • Could be profitable: – To purchase batteries in the new energy regulation? – To contract an ESCo? EPC, ESC?
  5. 5. 5 Energy systems operations • HVAC system operation could represent between 40% and 60% of the energy bill of the building I manage. – Should I use the three chillers at the same time? Should I use one, and then at certain external temperature the second, and then the third? – What should be the leaving water temperature? – What should be the start/stop time schedule? – What should be the set-points? – People are claiming for more comfort. Should I warm more the rooms? Howe much extra energy would I pay?

  8. 8. 8 EnRiMa DSS functionalities: Support to strategic decisions and Risk Management • The tool in the strategic module considers the following risks: – Energy prices evolution – Energy loads evolution. • It also considers: – Technologies: • Electric, thermal generation, • Electric, thermal storage, • Investment, operation& maintenance costs, • Energy prices, • Energy demand – ROI of the investment.

  18. 18. 18 Conclusions • Building Facility Manager needs a Decision Support System for energy infrastructure investment and operation analysis. • EnRiMa DSS provides such a support by means of an strategic and operational modules. • Risks in the energy prices and energy loads are managed by the DSS. • HVAC systems could represent up to 40% to 60% of the energy bill of the tertiary buildings. • One hour of non using HVAC system could represent 5% (Tecnalia M1) of HVAC system savings. • 1ºC of set-point relax in the inner temperature could represent from 3% (Tecnalia M1) to 7% (KUBIK) of savings, depending on the building and HVAC system characteristics.
