Net Zero Energy Walgreens in Evanston, Illinois
Imager borrowed from evanston.patch.com
Combining efficient energy use with wind and solar energy production, the new Evanston Walgreens will have net zero energy use. See the article here.
Too bad the new WECS ordinance being considered for Culver would stop a store like this from coming into Culver. (A Walgreens would best fit in a C-2 Zoning District which does allow for the use of a WECS, but the further restriction that no WECS maybe located within 1500 feet of an R-1 Zoning District would make it virtually impossible to place such a store within Culver’s Town Limits.)
Evanston is north of Chicago which generally would put it in a latitude where solar energy collection has diminished returns. It’s proximity to Lake Michigan does make it likely to receive fairly consistent winds.
Telkonet Thermostat

Check out the Telkonet thermostat. I’ve previously written about the Nest thermostat and the Honeywell Wi-Fi thermostat. Telkonet claims to take it another step further. Not only is their thermostat programmable, accessible from the Internet and “smart”, but it can calculate roof comfort by aggregating data like time-of-day, solar load, brightness, humidity and occupancy patterns. It’s Ecoinsight feature determines when a space is occupied or vacant and reverts to preset temperature limits. Check it out at their site here.
The Ecoinsight thermostat is more for commercial applications than the other two. While it has Internet connectivity, it may require special networking in order to access it. This is more efficient where you have multiple installations.
Culver: Nice Scientists Not Welcome
At the October Plan Commission meeting, the discussion on WECS’s continued. (Previously discussed here.) The Commission could not come to enough of a consensus to formulate a new Ordinance but they did take a series of votes that defined several of the issues. It would appear that proponents of banning WECS’s are achieving most of their goals. If they proceed along their current path, Culver residents would not be allowed to have a WECS that produces more than .5 kilowatts in the lake district, park district, and R1 residential district as well as within 1/4 mile of any of those districts.
I would still contend that the proponents of the ban are too focused on their distaste for the aesthetics of current wind turbine technology and fail to consider the advantages that could come from advances in the field.
Shipping Container Living Space

Brent Martin and I have had several discussions about using shipping containers as living space. Apparently someone beat us on the implementation. London-based developers Urban Space Management used shipping containers to create Container City, a 22-unit modular building. I read about it in the April issue of Multi-Family Executive. You can read the entire article by Linsey Isaacs on their site here. I also read an article recently where Ball State University was experimenting with the idea as housing in third world countries. Another million dollar idea lost to quicker minds…
LED vs HID Wall Pack Fixture
I generally feel that upgrading electrical fixtures and devices to the newer energy-saving devices is the easiest green energy to justify. Great strides are being made in this area to the point that my average client can see savings with a short pay off time. This is often something that shows gains with a one-to-one swap of new for existing fixtures. Further gains can be achieved by designing around the new fixtures and adding energy-saving controls.
One of my supplier reps was in yesterday and shared the following analysis that he completed for one of his manufacturing clients who was considering upgrading their existing exterior wall pack lights from HID (High Intensity Discharge such as High Pressure Sodium or Metal Halide) to LED (Light Emitting Diode):
These are the wall pack security fixtures you see high on the wall around factories, warehouses or buildings with parking near their wall.
Fixture prices:
HID TWH400MTB w/lamp $218
LED TWHLED 30C 50K $450
At $0.08 energy rate, 10 hour/day, 365 days/year the energy savings is $102.79/year.
LED = In a ten year time frame you would spend $450 for the LED fixture and $305.80 for energy use.
HID = In a ten year time frame you would spend $218 for the HID fixture plus change the lamp four times and the ballast once. 2 hours labor times 4 times is 8 hours. The cost for the four lamps and the one ballast is $124.
