A Thermal Image measures the heat of an object relative to other objects. The pictures generally show the heat loss of the buildings in question. Most were taken in January 2017. using a FLIR -i-phone camera attachment. There's an image of the Chicago Skyline, an image of the infamous Aqua Tower an image of the inspirational "Tighthouse" in Brooklyn circa ~ 2012, and other illustrative images thrown into the mix. The FLIR camera measured heat differences only. Blue is cold. Yellow is hot and red hotter still. It should be quite easy to discern Ellis Passivhaus by its shape and sign as should the other house in the row. The internal temperature of Ellis Passivhaus at the time approximated 65+ F. The ambient outside temperature ~ 20 F or less. The balance of the images are from 57th and Woodlawn, the Quad Club, and 49th and Kimbark and the immediate area around Ellis Passivhaus. The house immediately to the south of Ellis Passivhaus had been unoccupied and without heat for a few months.
Fifty percent of global carbon emissions result from insidious building energy loss. A Chicago consumer relies on Peoples Gas for some 80% of its energy needs and on Comed for the balance. With this relationship a combined Peoples Gas and Comed bill of $350 per month translates into over 95,000 pounds of carbon per year or some 260 pounds per day. The average NFL player weighs ~ 260 pounds. This amount of energy requires ~ 177 PV panels. Using Energy Star appliance assumptions and the PHPP (Passivhaus Planning Package) Building Model of Ellis Passivhaus, Ellis Passivhaus requires ~ 9500 kWH of energy per year for all uses which equivalently translates into ~ $44 per month. However, Ellis Passivhaus is combustion free (no NatGas.) It relies on Comed for 100% of its grid sourced energy. Therefore it's monthly grid source energy bill will ~ $124 per month all else equal because NatGas costs ~ 80% less per unit of energy. That said, carbon production for Ellis Passivhaus will be reduced to just 26 pounds per day. Ellis Passivhaus can accommodate approximately 24 PV panels which would likely produce over 12,000 kWH per year. Each PV panel can be expected to produce ~ 500 kWH per year and defray ~$75 per year and $6.25 per month of Comed energy expense at current rates. 9500 kWH one year divided by 500 kWH per panel per year equals approximately 19 panels. Annual HVAC and hot water requires some 4300 kWH or some 9 panels. Hence, Ellis Passivhaus represents a Zero Energy Design (ZED) building.
