Ahhhh good tip, and thanks! :tup:

Mat pour in progress...

Full building permit was issued yesterday for Essex on the Park.

Bananas.....coming soon. And by that mean above ground.

'harryc' was also taking pictures. It had been a number of years since we last crossed paths. Nice chatting with you again, Harry!

Tower crane will be set Sunday/Monday 7/9-7/10.

You meet the nicest people hanging out on parking garages.

Seasonal Loss of Radiant, Solar Thermal Energy at the Conrad Hilton

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.

http://www.phisicalpsience.com/publi..._08jul2017.jpg

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.

I felt like I was in science class again after reading that. Interesting to think about though as it absolutely is right in the way of the sun for months of the year(during some hours of the day)

Shadow Pricing - NO . Even if it was a significant cost - NO.

The time of year when the sun would be a benefit (winter) is when the incident angle is the greatest, this is part of what makes it so cold up here.

Lots of parts delivered to the site today for the tower crane, it should start going up this afternoon and complete tomorrow if the weather holds.

Great photos Bvictor!

Lol...

But in all seriousness, now I get why some of the gay members of our community have requested shots of the construction eye candy. That guy is ripped on a whole nother level. Probably pretty good workout to swing a 20 lbs sledge over your head while hanging halfway off a tower crane.
