### Envelope Sensitivity In addition to overall energy use modeling, parametric analysis was conducted to understand the sensitivity of various envelope characteristics on building energy use. Figure 2 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 EUI and TEDI. The line represents the overall trend for each parameter, the baseline values are marked by dark blue dots. In accordance with the energy use characterization discussed above, the overall energy use can most benefit from further improvements to window U values, followed by reduced window areas and improvements to wall and roof insulation. It is recommended that the design team explore the feasibility of achieving wall and roof performance as close as possible to R-35 and R-45 respectively, and window assembly performance as close as possible to assembly U-0.25. These recommended values are highlighted by light blue circles. Note that while designing to reduce infiltration rates will have appreciable impact on both EUI and TEDI, current models assume levels that are mandated by CaGBC for both baseline and target designs.

#### Energy Performance Benchmarking As discussed in the previous sections, the baseline design with all performance parameters defined at ASHRAE 90.1-2010 Appendix G minimum requirements shows an EUI of ${formatEUI_SI_IP(126)} and a TEDI of ${formatEUI_SI_IP(47)}. Incorporating the current proposed constructions (R-30 walls, R-40 roofs, U-0.35 window assemblies) reduces the EUI to ${formatEUI_SI_IP(111)} and TEDI to ${formatEUI_SI_IP(38)}. Both these cases assume a baseline HVAC system that incorporates VAV air handling with electric reheat fan powered terminal units. Switching to the proposed systems with air source VRF served by an energy recovery dedicated outside air system (DOAS) reduces the EUI to ${formatEUI_SI_IP(72)} and TEDI to just under the target of ${formatEUI_SI_IP(34)}. Based on these results, the current proposed design demonstrates an overall energy savings of around 43% over the baseline and meets the TEDI target. Finally, improving the envelope properties to recommended values (R-35 walls, R-45 roofs, U-0.25 window assemblies), based on the results of sensitivity analysis, offers appreciable reduction in heating loads, reduces the TEDI appreciably to about ${formatEUI_SI_IP(25)}, and the EUI to ${formatEUI_SI_IP(69)} increasing the savings to 45% over the baseline. In terms of GHG emissions, the baseline energy use levels translate to ${formatGHG_IP_SI(32.2)}. The current design with proposed constructions and HVAC systems reduces this to ${formatGHG_IP_SI(18.4)}. Note that this analysis assumes an average grid emissions intensity of 20 gCO2e/kWh in accordance to the latest federal NIRR reporting. Figure 4 presents the comparison of EUI, TEDI and GHG Intensities for the different studied scenarios.

\n### Introduction\nIntegral Group developed a whole building energy model for the Centennial College A-Block expansion project in Toronto, ON. This study is designed to help characterize the proposed design energy use and to study the sensitivity of different envelope component characteristics on building energy use. The primary purpose of this analysis is to benchmark the project against an ASHRAE 90.1-2010 baseline and to the check whether the project design is set on track to achieve a Thermal Energy Demand Intensity (TEDI) under ${formatEUI_SI_IP(34)} in compliance with requirements of the Zero Carbon Building (ZCB) Standard published by the Canada Green Building Council (CaGBC) for ASHRAE Climate Zone 6.\n

\n### Energy End Use Characterization\nFigure 1 below shows the breakdown in energy by end use for the baseline design. 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. The total energy use intensity (EUI) of the baseline design, with all performance parameters defined at ASHRAE 90.1-2010 levels is approximately ${formatEUI_SI_IP(126)}, with 37% of this attributable to space heating (TEDI ${formatEUI_SI_IP(47)}), 18% to plugged equipment and about 15% to lighting energy. The load components on the right show the key drivers of proposed design energy use. Solar gains form the largest load component, constituting 40% of the total cooling load. In terms of heating, the majority of the load results from window conduction losses followed by outside air heating.\n

\n### Parametric Analysis\nTo better understand the effect of different performance characteristics on building EUI and TEDI, Figure 3 presents a parallel coordinates plot where each of the first six vertical axes represents a performance parameter and its evaluated properties, and the last two axes show the EUI and TEDI 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 and TEDI. 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
