Obtaining HDD/CDD projections for USA/Canada/Brazil

edit

I'm looking at using the EU-developed Carbon Risk Real Estate Monitor (CRREM) tool for assessing properties in the US, Canada, and Brazil. The CRREM guidance says that HDD and CDD values should be added for each location for 2015, and for 2045 under RCP 4.5 and RCP 8.5 warming scenarios.

I can get the 2015 HDD and CDD from DegreeDays.net but I'm not aware of anything similar for projected degree days. Does anyone know where to look?
