Phase one of the website will not include e-commerce (i.e. paid membership) but the BIT team wants to restrict access to some parts of the site, including the full Best Practices documents and the forum. This means we'll need a rudimentary paywall, directing users to register for full access.  Current registered users of BuildingGreen and... Read more

Air movement keeps occupants comfortable when it's warm, so cooling setpoints can be higher, and natural ventilation is a viable option even at higher temps and humidity.

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

ASHRAE 209 in all its glory has been uploaded. This will impact our architectural process, for better or worse, so we should embrace it and learn from it. The revised AIA Energy Modeling Design Guide (due out next year) has been timed to correspond roughly to 209 coming out and will include references to it. The first few energy modeling '...

Does anyone subscribe to Green Badger? Do you find it valuable?

Hive mind,

We recently learned that 3M has discontinued the production of their 3M Daylight Redirecting Film (https://www.3m.com/3M/en_US/building-window-solutions-us/solutions/dayli...). This product was selected by an architecture client last year as the optimal daylight/glare control strategy for a school project, and we're assisting... Read more

Does anyone know of a good summary of state and local energy code adoption for new building and ordinances for existing buildings? I know of this energycodes.gov site, but it feels somewhat misleading when you dig into it. For example, in CO, it suggests there is no min code, but there is, and it doesn’t show the extent to which local govs are... Read more

I'm sure many of you remember when Greenbuild 2020 was scheduled for the week of the presidential election and if was shifted back one day. 

If anyone has small kids and have gone to book your Greenbuild 2022 travel, you've potentially noticed (as I have) that I'll have to travel on 10/31 and will miss all Halloween activities with my... Read more

Greetings, SDL network - We are attempting to resolve an issue with how data center projects calculate baseline EUIs for the AIA 2030 Commitment and could use some help from this network. With projects that comply with code prescriptively (i.e. not energy modeled), we have found the default baseline assumptions within the DDx platform are not... Read more

Hi All,

I wanted to share an exciting opportinity with this esteemed group: Placetailor is seeking out a Mechanical Engineer to add to their growing team. They are located in Boston, MA and focus on Passive House, Low-energy Design, and they have for two years running meet the tenets of the AIA 2030 Commitment! This is an exciting place... Read more

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Practitioners interested in reducing the embodied carbon of buildings are likely now used to considering the impact of different materials, like mass timber or low-carbon concrete. Low-carbon... Read more
