Championing the
Changemakers

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

We should probably agree on the correct spelling for what we at BuildingGreen are calling "BITuser." I noticed that on the Salesforce portfolio screenshot provided by Dennis, it's spelled "BIT User."

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... Read more

I'm looking to compile an outdoor weather station for a local project, and we'd like to add local outdoor CO2 information to our data. I usually work with Onset HOBO products, but they don't offer an outdoor CO2 sensor. Their weather stations can take data from any CO2 sensor with an analog output - does anyone have any suggestions?

Is LEED Online mind-numbingly slow today for anyone else? Or is it just me? I may give up and try again tomorrow. Frustrating as I was hoping to submit a final review today. :(

Hi everyone - in doing a carbon footprint for our firm, does anyone know if buildings that we design as Architects considered scope 3 emissions, or are they beyond the boundary of emissions? LMN's buildings, despite best efforts, are cumulatively multiple orders of magnitude above our scope 1 and 2 emissions. We have never included these... Read more

I'm working with a project team that is looking into bird control options to prevent nesting/roosting/pooping on the scrim that is designed to scrim their building's facade.  They are looking at electrified tape, repellents, laser systems, etc -- Options that don't dramatically impact the building design.  The products they're looking at claim...

Recycled plastic paneling is an appropriate use for some of the various post-consumer plastic materials entering the waste stream—in particular, high-density polyethylene (HDPE) from milk and detergent bottles.

Hi all,

I'm curious how various firms are approaching their own office projects, re green building certifications. I'm especially interested in medium-large firms that have multiple offices, but policies and processes from small firms may still be instructive.

Do you have a firm-wide policy or is it a case-by-case thing? Has... Read more
