Perhaps this issue for structures located in the mid to higher, northern and southern latitudes has already been resolved before and or elsewhere, but I have been reviewing a rendering of Essex on the Park (Chicago Architecture, 2017) and curious if the voluminous Conrad Hilton is in a position to pass on additional heating cost incurred during late fall to early spring months because of the new Essex on the Park.
I ask, as the Conrad Hilton since the time it was constructed, has for the most part, been receiving ~1.37 kW/m^2 of radiant thermal solar energy, minus adjustment for the Sun’s incident angle that post construction will no longer receive, the Conrad Hilton being in the shadow of Essex on the Park.
Yes, radiant, solar thermal energy is loss on cloudy days, but such losses are "force majeure" events, where as the loss radiant energy from the rising of Essex on the Park is of an "engineered nature". Yes, the new structure will provide very brief, partial coverage from solar radiation in the summer. However, the most taxing times of the year for HVAC systems is when the Sun in the northern hemisphere at noon is at a low incident angle relative to the zenith, resulting in short shadow lengths, the Sun being ~19 degrees from zenith near the summer solstice. The building Essex on the Park during the winter season because of the Sun's ~65 degree incident angle with the zenith at noon, producing a very long, encompassing shadow over much of the volume of the Conrad Hilton and other lower structures in the vicinity.
