• 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

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
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
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?

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.

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.
