    Residential HVAC Sizing

    I'm a building plans examiner in FL, and the energy code requires the capacity of the installed equipment to be no more than 115% of the load. Typical load calculations are ~80%SHR, while the capacity is always figured at 70% SHR. This gives a unit which has less sensible capacity than load...

    Wind Loads on Open Buildings in ASCE-7

    I posed this question in Sturtural-other, but this looks like the better forum. Please excuse the duplication, but my question is how to determine wind loads on open buildings with other than monoslope roofs. ASCE-7 Chapter 6 seems to sidestep this issue entirely, as does the "Guide to ..."...
