Glazing connects occupants to the outdoors, but with so many opportunities for air leakage, poor insulation, and thermal bridging, glazing is the primary weak link in building energy performance.

BuildingGreen approves glazing that offers strong energy performance properties for a variety of... Read more

Hello all!

I'm new to the group, and so excited to be here. Two part question here (as we think about processes and new year goals).

I am at a smallish firm (20 people) in Boston helping to reform our processes to enable even those that are not steeped in sustainability at a daily level to be comfortable looking for opporutunities... Read more

If only a few of the Best Practices will have checklists, which will be included under the "Implementation Toolkit" tab, I'm thinking we can simplify them (compared with LEEDuser).

I've attached a screenshot of a LEEDuser checklist. But I don't think BITuser will need the four types of icons, and the legend will take up more space than... Read more

Thanks to SERA especially David, Kira and Clark for an inspirational conversation with Paul Hawken about his latest book. I know I needed a positive perspective! Then I found this great "Regeneration Anthem" song and had to share.

Happy Fall to all.

Building materials emit massive amounts of carbon long before the lights go on.

In this course, BuildingGreen takes an analytical look at the greenhouse gases that are emitted in the process of constructing our buildings in the first place—the embodied carbon. The report focuses on how architects and designers, working with other key... Read more

Hi All,

Has anyone dug into ASHRAE 2016 as part of the new v4.1 requirements or as codes start to adopt it? I recently presented on this and thought I should check my math to make sure I'm understanding and communicating this correctly.

My understanding is that there is a new reference baseline, that is essentially the ASHRAE 2004... Read more

Good morning, All,

Just a bit of news this morning.  My family and I are moving back out west!  I am continuing in my current role with EwingCole, but will be doing so from Portland, Oregon.  Although North Carolina has a been a wonderful place for us for the past 13 years, it is time to be close to family in the northwest and southwest...

Hello,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

Hello Gurus,

I have a client (bldg owner) who has asked me to recommend a list of firms who have the internalized resilient design in their practice.

They are *not* asking for resiliency consultants right now, but for firms that they might hire for "regular" capital projects, but since resiliency is high on their priorities, they... Read more

Hi Everyone, 

Has anyone had success in finding organizations or programs that will recycle the hard hats? We are looking into options for recycling our expired hard hats that can no longer be used. Ideally, we would want to use a company with facilities across the country but we are open to any suggestions or ideas you all may have....

I'm sure most (if not everyone) is aware that LEEDv5 is under public review until May 20, 2024. I know I need to make time to flip through it, review, and comment, but I'm having a heckuva time protecting the time in my calendar to do that. Anyone interested in joining me for a 60 - 90 minute meeting to do this together as an accountability... Read more

Asking for a colleague:

"Have you ever had a large number of fire retardant tarps used to temporarily enclose a building during construction? Do you know of any solutions for recycling/reusing them or another product that doesn't use toxic fire-retardants that meets the performance criteria?"

I think we've all seen poly or fabric... Read more

Are there any metrics for % increase for building PH vs conventional?  These questions are always really hard- especially when there are none to compare to in area.
