Pint-flush and non-water urinals can save tens of thousands of gallons of potable water per year. A single non-water-using urinal can save more than 10,000 gallons of water per year compared with the U.S. EPA standard of 1.0 gallon per flush (gpf).

When older 3.0 gpf urinals are replaced, the savings can be as great as 50,000 gallons... Read more

Hello all,

I need future weather files for a project. We are looking at three years, 2050, 2075, and 2095 using two climate change scenarios, low emissions, and high emissions. I have seen ARUP's Weathershift site that uses RCP 8.5 and RCP 4.5. Are we assuming that 2.6 is not achievable? I would have used this as a low emissions scenario... Read more

Hello there, 

I am working on a project with indoor plants and active green walls. I would like to design lights for growing plants and people at the same time (which seems to be a non-obvious problem). 
 

I was thinking of Philips, GE, Shneider Lighting, etc. Would you recommend someone I could talk to and eventually engage... Read more

Hi friends,

We recently tracked our water consumption on site during the structural demolition of some existing reinforced concrete buildings.  The new OSHA silica regulations required us to keep dust to virtually zero, so we had a bunch of mist cannons and water hoses pumping water around the clock.  We consumed ~855,000 gallons in a...

We are looking at installing an aerobic biodigester in a commercial kitchen for an office client that is VERY concerned about zero waste.  Basically, this system takes food waste, treats it with micro-organisms to remove organic matter, and turns it into water of high enough quality to go straight to the sewer.  The manufacturer we are looking...
