It is my understanding that the loads are calculated based on the "Indoor Design Temperature" and not the setpoint temperature. You can generate hourly reports using the "Space" blocks in the hourly report blocks however you would need to make a separate block for each space. <br>

<p class="MsoNormal">I’m modeling a 1940s-era apartment building for a geothermal retrofit. The current heating system consists of hot-water radiators supplied by gas-fired boilers. Cooling is supplied by window air conditioning units in each apartment. The ultimate objective is to generate building space heating and cooling loads to size a heat pump and ground heat exchanger – by space heating and cooling loads, I mean the total heat which has to be added or removed by the HVAC system to maintain all conditioned spaces at their set points.</p>
<p class="MsoNormal"> </p><p class="MsoNormal">Currently I’m generating hourly loads from the Building HVAC hourly report block using variables 1 & 2, entitled “Building cool load (coils + losses&gains)” and “Building heat load (coils + losses&gains)”. Are these the right variables to use, or do I need to look somewhere else?</p>
