### Energy End Use Characterization Figure 2 below shows the breakdown in energy by end use for the building. The energy in this case have been calculated for the baseline building design using envelope parameters and lighting values from SB-10 Division 3. The modeled HVAC system is a packaged VAV with a natural gas heater to provide heating as specified in SB-10. The total energy use intensity (EUI) of this design case used as a baseline is approximately ${formatEUI_SI_IP(297)}. In the graphic, the energy sources are aligned on the left side of the graphic, while energy sinks (conduction losses, equipment gains, etc.) are aligned on the right side. Of the total EUI of ${formatEUI_SI_IP(297)}, almost 50% is attributable to heating energy, followed by 14% to equipment energy and 11% to lighting energy. The load components on the right show the key gains and losses attributable to the heating and cooling gains. The heating load is predominantly attributable to heating the incoming outside air in the vehicle bays and the other parts of building and account for about 60% of the total heating load. Additional 17% loads is required for the reheat in order to maintain the humidity in the space. The envelope has a bigger impact on the D2Hub and education part of the building. On the cooling side, cooling the outside air constitutes 27% of the cooling load followed by occupants, lighting and equipment.

### Envelope Sensitivity A detailed parametric analysis has been conducted on the baseline design as discussed above, to understand the sensitivity of various envelope characteristics on building energy use. Figure 3 below presents these results with the horizontal axes showing incremental changes in the studied parameter, and the vertical axes showing the impact of these changes on building TEDI or building CEDI (selectable from the dropdown). The line represents the overall trend for each parameter, the baseline values are marked by dark blue dots. As discussed above, the heating load of the building drives the energy use of the building. While sensitivity based on TEDI is an important factor, ensuring a lower cooling demand is equally necessary to avoid upsizing of the active cooling system. It is recommended that the design team design the walls with an insulation value of at least R-40 and roof of at least R-50. The window u-value is recommended to be less than U-0.2 for the entire assembly which can be achieved by thermally broken triple glass windows. Infiltration plays a very critical role in reducing the thermal demand of the building and it is recommended that the building is designed with a tight envelope later verified by a blower door test. The currently planned window-to-wall ratios are in the range of the optimized values, but as seen below, the academic and office/fitness areas are sensitive to the higher/lower WWR.

#### Energy Performance Benchmarking (WIP) As discussed in the previous sections, the SB-10 baseline design with envelope and lighting parameters defined in the standard shows an EUI of ${formatEUI_SI_IP(297.6)}. This is reduced to ${formatEUI_SI_IP(264.1)} when the recommended envelope of R-40 walls, R-50 roof, triple glazed windows and shades with cut-off angle of around 60 degrees is used. Additionally, this case also includes a vestibule in the vehicle bay, that helps to reduce the heat loss when ambulances leave the facility. This combination provides an EUI reduction of about 11%. Changing the HVAC system to a decoupled system by including a dedicated outdoor system (DOAS) to provide fresh air, improve the heat recovery effectiveness and reducing the lighting power density (LPD) can bring the EUI down to approximately ${formatEUI_SI_IP(190.6)} - approximately 36% lower energy use than the baseline. The next bar shows the energy use when the HVAC plant is changed to an air source heat pump for heating and cooling. An ASHP provides thermal energy at a much higher efficiency thereby reducing the EUI by 48% to ${formatEUI_SI_IP(163.4)}. Replacing the ASHP with a ground source heat pump and utilizing ground as a heat rejection source can help bring the EUI down further to ${formatEUI_SI_IP(152.2)}. This option relies on stable and balanced ground temperatures and includes electric boilers as backup heating options. Lastly, enhancing the heat recovery ventilation effectviness to 80% can reduce the EUI (and TEDI) further to ${formatEUI_SI_IP(139.2)}. This option is the current proposed HVAC design option. A 800 kW PV array mounted on the rooftop can offset electricity to make the project with the proposed HVAC system a net zer energy and net zero emission builidng. A slider has been provided to assess the EUI offset with different PV sizes.

A full energy model update, including re-drawing the energy model geometry, was performed in order to capture the full scope of the impact on the building energy use intensity (EUI) and thermal energy demand intensity (TEDI).\n

\n### Parametric Analysis\nTo better understand the effect of different performance characteristics on building EUI, Figure 1 below presents a parallel coordinates plot where each of the first seven vertical axes represents a performance parameter and its evaluated properties, and the last axis shows the TEDI and EUI resulting from the selected combinations. Putting constraints on one of more attributes, for instance, allows for the exploration of how changing the remaining attributes affects the result. The dark lines in the chart are results for combinations simulated using the whole building energy model. The lighter lines represent results from all other combinations that are generated using statistical surrogate models that utilize data-driven approximation techniques.

\n### Parametric Analysis\nTo better understand the effect of different performance characteristics on building EUI, Figure 4 below presents a parallel coordinates plot where each of the first seven vertical axes represents a performance parameter and its evaluated properties, and the last axis shows the EUI resulting from the selected combinations. Putting constraints on one of more attributes, for instance, allows for the exploration of how changing the remaining attributes affects the EUI. The dark lines in the chart are results for combinations simulated using the whole building energy model. The lighter lines represent results from all other combinations that are generated using statistical surrogate models that utilize data-driven approximation techniques.
