### Envelope Improvements and Heating Demand One of the key objectives of this study is to identify envelope retrofits such that building heating loads can be met with low temperature (${_.round(c_f(48.8))}°${unitSelection.unit === "IP" ? "F": "C"}) hot water. Based on discussions with Yale, hot water temperature has successfully been set back to ${_.round(c_f(48.8))}°${unitSelection.unit === "IP" ? "F": "C"} for periods when the outside air temperature was above ${_.round(c_f(10))}°${unitSelection.unit === "IP" ? "F": "C"}. This analysis, therefore, is based on the premise that low temperature hot water can successfully meet space heating loads when ambient temperature is above ${_.round(c_f(10))}°${unitSelection.unit === "IP" ? "F": "C"}. Based on the results from the calibrated baseline energy model, the median load when the outside air temperature is around ${_.round(c_f(10))}°${unitSelection.unit === "IP" ? "F": "C"} is ${_.round(kw_kbtu(94))} ${unitSelection.unit === "IP" ? "kBtu/hr": "kW"}. For the purpose of this analysis, this load establishes the limit up to which low temperature hot water can be used effectively. Figure 5 below shows the range of heating loads corresponding to various outside air temperatures. The target load range, which is based on the identified heating load limit at ${_.round(c_f(10))}°${unitSelection.unit === "IP" ? "F": "C"}, is indicated on the graph. The areas in dark red represent loads that fall outside of the target range, while those in light orange indicate loads that are within the target range. Using the dropdown menu, you can see how the loads reduce with each envelope upgrade scenario. With Envelope Upgrade 1, it’s possible to utilize low temperature hot water as long as outside air temperatures are above ${_.round(c_f(5))}°${unitSelection.unit === "IP" ? "F": "C"} (roughly 72% of the year). With Envelope Upgrade 2, the outside air temperature can drop to approximately ${_.round(c_f(-5))}°${unitSelection.unit === "IP" ? "F": "C"} (roughly 96% of the year). However, in order to meet the building heating demand at all reasonable outside air temperatures (down to ${_.round(c_f(-18))}°${unitSelection.unit === "IP" ? "F": "C"}), the building will need to incorporate envelope improvements equal to or better than those represented by Envelope Upgrade 3.

\n### Heating Load Distribution\nAt any given outside air temperature, there is a range of possible heating loads due to variations in solar gains, occupancy loads, equipment operation, etc. While the graph above (Figure 5) represents this range as a box-and-whisker plot for all corresponding outside air temperatures, the graph below (Figure 6) shows the frequency distribution of loads for a single temperature (+/- 1°C). The existing building conditions are represented in grey, while the load distribution for each envelope upgrade package is shown in light orange (for loads that are within the target range) and red (for loads that are outside the target range). This graph illustrates the frequency of a specific load for any given outside air temperature, for each envelope upgrade package. Note how the entire projected load range with Envelope Upgrade 3 is within the target, even at the lowest outside air temperatures.
