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?

Kim is involved on the ASHRAE 209 development and has been advocating that the AIA, ASHRAE and USGBC align around this standard. Personally I think this is a good idea as I expect that this standard could easily make it's way into regulations and contracts... Read more

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more
