Architectural roll-out work is one of my specalities. You know a client needs a whole lot of the same building all over the place. Mostly this is restaurant architecture but in this case the client was a bank. One of the most interesting things about this type of work is when I get to do experiments Womens Shane Doan Jersey , making variations in the building and comparing the results. This is the story of one of those experiments. I think you will find the results interesting.


It all started when I was designing a lot of banks in the Chicago area. These were retail branch banks about 4,100 square feet each. The first bank was in Deerfield IL and was built with good quality commercial construction. The building had a steel frame infilled with 6 inch metal studs, filled with 6 inch fiberglass insulation for the walls, the roof was metal deck and bar-joist with 3 inches of insulation board. The second bank was in Wheaton IL about 20 miles away, so both building get the same weather. We only changed 3 elements Womens Clayton Keller Jersey , the buildings were other wise identical. One, the wall insulation was changed to foamed in place low density polyurethane, this changed the wall insulation value from about R-18 to about R-20 but the air infiltration into the building drops to almost nothing with the foam because it expands and sticks to everything. Two, we doubled the roof insulation from 3 inches to 6 inches, increasing the insulation value from R-18 to R-36. Third Authentic Jason Demers Jersey , we changed the windows from 1 inch clear low-e sealed glass units to tinted low-e 1 inch sealed glass units. Each item was bid as an additive alternate so we could obtain hard numbers for what each item cost and not just rely on estimates. The foamed in place insulation in the walls cost an additional $9,150. The thicker roof insulation cost an additional $5,300. The tinted glazing cost an additional $3,800. The grand total for all three alternatives was $18,250 or put another way $4.45 a square foot. To complete the experiment I tracked the energy usage for a year and put together a comparison chart to ensure it was money well spent. You can judge for yourself Authentic Alex Goligoski Jersey , but I think the results are stunning. Gas consumption was cut by 62% and electrical consumption was cut by 25% that is a saving $5,090 in the first year. That is $424 a month every month.


People always ask the wrong question when it comes to energy conservation. They ask how long is the payback. The answer is about 3 years and 7 months. The correct question is what is the affect on cash flow, and the answer is $283 per month for 20 years then it jumps to $424 per month. What, I am talking about is the fact that buildings are financed so $18,250 is borrowed and then paid back from cash flow Authentic Oliver Ekman-Larsson Jersey , at 7% that is $141 a month for 20 years. $424 in savings take away $141 in dept payment is positive $283 a month. For this calculation I use $0.09 a kilowatt-hour and $1.00 a therm, both prices have fluctuated above and below these averages but I don’t think it affects the out come on the experiment. Each of these three items thicker roof insulation, tinted glass and foam insulation are now standard for my buildings and with this hard date clients are easily convinced it is money well spent. One more thing the client allowed me to share this data but not their name. I hope you understand.

SAN FRANCISCO, Aug. 5 (Xinhua) -- Two environmental engineers at Stanford University have developed a computational planning tool to help urban utilities combine two water supply strategies - collecting stormwater runoff and recycling treated wastewater - into an integrated system that replenishes aquifers.


While collecting stormwater runoff and recycling treated wastewater are usually separate processes that can create costly and underused infrastructure Authentic Derek Stepan Jersey , underground aquifers that have been over-tapped for years are in need to be replenished and the U.S. federal government projects that 40 states across the country expect water shortages by 2024.


Inspired by water reuse leaders like Orange County in Southern California, Jonathan Bradshaw, a graduate student in civil and environmental engineering at Stanford, and Richard Luthy, a professor of civil and environmental engineering at the university in Northern California Authentic Christian Dvorak Jersey , have worked out the hybrid approach and the planning tool, known as AquaCharge.


Utilities to collect stormwater are designed to channel rainfall during the wet season into ""spreading basins,"" which are essentially leaky ponds that are porous enough for water to percolate back down to an aquifer. Although the approach is effective, engineers typically design the basins to be big enough to capture large volumes of water, and they remain largely idle through the dry months.


By some estimates Authentic Max Domi Jersey , according to Stanford University in a news release this week announcing the development of AquaCharge, Los Angeles County's spreading basins on average percolate only 12 percent of their theoretical annual capacity.


Wastewater recycling poses different challenges. Some utilities treat wastewater to the point that it can be used safely for agricultural irrigation or certain industrial purposes, such as circulating through the cooling towers of a power plant. Such uses reduce the burden on aquifers or other water sources. However, regulations require that this recycled water be conveyed in a pipeline separate from drinking water pipes.


Although many utilities have a large potential to produce recycled water, the high cost of such separate piping systems means that only a small fraction of this potential gets developed. So Authentic Richard Panik Jersey , most treated wastewater flows back in.
