Hi All! 

We have had a few multi-family projects consider this single package vertical unit with integrated ERV, but we haven't pulled the trigger for fear of the unknown. Our local engineers aren't sure how it actually performs and worry it may not meet code requirements for separation between exhaust and intake. Has anyone else used... Read more

Anyone aware of tools or workflows for modeling of a specific outdoor space and effective surface temperatures?  We've done a goodly amoutn of microclimate simulations, but never explicitly factored in the ground surface, in terms of emissivity and other related factors.   

Hello,

As with most people I feel some what helpless about what the next 4 years will bring. Heather Clark, Senior Director for Building Sector Climate Policy at The White House thinks that a big bill will be presented in the new year and one of the small items in there will be the axing of the Inflation Reduction Act. What she made... Read more

There seems to be a slight glitch in that it was posting Seonhee's picture (love Snoopy!) for the post that Duane sent in - is that correctable?

**Just noticed that you can click on the "Edit" tab on the post and correct (e.g. mis-spelled names (Sorry, Seonhee!).**

Welcome to the quiz portion of Go with the Flows: The Promise and Peril of Hygrothermal Modeling

2. Name four instances in which to consider using hygrothermal modeling... Read more

Hi Green Gurus!

I am trying to find a source for this chart/graph illustrating the relative cost of design and construction versus the long term operational and occupant costs. Any thoughts are appreciated.

On Thursday, September 27 at 2PM Eastern Time you can join the first BuildingGreen Communities webinar where we will share key takeaways from the 11th annual Summer Sustainable Design Leaders Summit (@ the Garrison Institute in upstate New York). Our new webinar format using Zoom will allow for interactive questions and comments throughout. If... Read more

Hi! Just saw this White House press release stating that federal suppliers will need to report on scope 1 & 2, and relevant scope 3 emissions and climate-related financial risks as well as set science-based emission reduction targets. The cutoff for disclosure requirements is $50m in federal contracts. Curious whether this affects any... Read more

Hi folks,

Our next private webinar is coming right up:

I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

At Living Future last week a woman from Google asked about cost comparisons and I shared that the City of Santa Monica conducted a study analyzing the costs of a prototypical mixed-use project for a Living Building vs. LEED v4 Platinum vs. code compliant (Title 24, part 6). I thought this group might be interested as well so here is the link... Read more

Hello everyone! I’m happy to be re-joining the group after a two year hiatus.

Pre-pandemic I got to participate in a few winter summits when I was Sustainability Director at Overland Partners in San Antonio. I’ve recently joined Mahlum Architects in Portland and I’m excited to re-engage in the conversation, this time from the West Coast... Read more

Hi folks,

BSR/ASHRAE/ICC Standard 240P, Quantification of Life Cycle Greenhouse Gas Emissions in Buildings, is out for Public Review until March 18. It covers what construction activities have to be tracked and reported and provides placeholder values to use during design. If you have input or suggestions on what would be needed to make...

We all know the climates are shifting, and the ASHRAE standard that gets invoked for energy codes is shifting along with them--though not in perfect sync.  Louisiana is leaping from ASHRAE 90.1-2007 energy code to 2021 IECC (boom!).  The 2021 IECC as published uses relatively old climate maps; for Louisiana, at least, the same as the 90.1-2007...

The IECC is accepting applications for committee members for its development of the 2024 International Energy Conservation Code (IECC). The responsibilities of the committees include:
