I understand electrical and plumbing, but why does the HVAC need to be bigger/smaller?

- MrLeap 2y agoJust conjecturing, but I assume an apartment contains more ovens than an office. Would probably make it take more cooling?
- Ekaros 2y agoThey also contain lot less people. Average person generates 70-100W at rest. Add that to what ever screens, computers, extra lighting. And it is not that big difference in load.
- deltarholamda 2y agoHVAC has to account for the BTUs produced by all equipment. An office might have one or two refrigerators per floor, maybe a dishwasher. Apartments will have one in every apartment. Ditto for ovens, dryers. Even computers and TVs.
- ArchitectAnon 2y agoOffices have a lot more people per m² all of them using computer equipment continuously for 7hrs/day so in my experience they tend to have considerably higher cooling loads. I know from experience that a typical high rise office building in London, UK will have no heating requirement for most of the year; it is in cooling mode most of the time.
- deltarholamda 2y agoYou have to account for peak usage, not median. At 7AM and 6PM, everybody has their stove or ovens going to make dinner, plus the washing machines and dryers. Building codes and practices are different for commercial and residential for good reasons.
