Looking for an example or case study for a building utilizing a radiant heating/cooling in climate zone 4a. General use type is office with some public assembly spaces, total of 85,000 sf.

As usual, everyone, especially mechanical engineer, is terrified by the thought of "condensation." So far, I read a DGWW case study, "Energy... Read more

Welcome to the quiz portion of Sustainable Sites: Primers from Environmental Building News.

Learning Objectives
Upon completing this course, participants will be able to:


1) Describe how invasive plants can harm an ecosystem, and why native plants are generally less work and less expensive.

On LEEDuser we divide checklists into multiple project phases. Specifically:

How many of these phases are relevant for BIT best practices?

Note that we also... Read more

Save the Date: If you'll be in DC for AIA's Conference on Architecture or just happen to live nearby, hold 6:00–8:30 pm on Wednesday, June 5 for this event.

We have partners! This event will be hosted by ZGF Architects (on their lovely rooftop patio) in collaboration with US Architects... 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

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?

Greetings friends.

Many of you have heard about the CARE Tool, (formerly the 2Build or not 2Build Carbon Calculator.) We are now in the final stages of bringing it online as a free, open access tool hosted by Architecture 2030. We are finalizing and aligning data and working with a web developer (the same one that brought us... Read more

Hi all,

Looking from insights from anyone who's been through WELL certification before - we've got a lab/office project pursing WELL down in Florida that is struggling to meet the turbidity level requirements of the WELL W01 prerequisite, specifically with the hot water supply, and we're not sure how to best remediate the issue.  Should...

Hi All, I was initially reluctant to share this, but I've seen similar posts and I think it's in line with our mission and interests so I'll go ahead with it.

Tomorrow 12/9 at 1 PM EST I'm moderating a panel of industry leaders in public health (as it pertains to buildings), construction finance, and project development to review the... Read more

Electrochromic glazing holds the promise of less glare and better energy efficiency with fewer moving parts. The reality is much more complicated and includes information you won’t... Read more

Hey group,

I'm part of the contractor team on a large commercial project pursuing LBC v3.1 Petal Certification, with one of those petals being materials. This requires the team to meet Imperative 10 Red List.

The ownership group has taken the responsibility of red list vetting as a task of their own. The construction team is to... Read more

Does anyone know of a source for finding the operational solid waste generated by typical building/use types (weight/sf)? I couldn't find anything on LEED, True, or EPA. I found this table but isn't by sq ft for many of hte uses. Waste Generated by Industry and Building Type (wastecare.com)

Not a green design question but a green firm design question... Finalizing the renewal of our Just certification, we're taking a fresh look at all our benefits & policies. We have already reviewed industry-wide survey data (AIA and PSMJ) but are interested in how the firms we admire (i.e., *you*) are approaching benefits in the transformed... Read more

The construction sector’s take-make-waste approach to materials needs an overhaul. Materials and construction account for an estimated 11% of global greenhouse gas emissions annually. At the other end of the life cycle, demolition in the United States annually generates 90% of some 600 million tons of construction-sector debris. Getting trashed... Read more

Hi,

I selected a new background photo for the home page (the previous one was the same as on LEEDuser.com). I found the photo here:

I needed to find something low-contrast that wouldn't compete with the text. I initially tried some of the stock photos... Read more

Love the profile of Anica as the "featured member" on AIA's website--congratulations, Anica!

It's great to see the "just do it" attitude to achieving the 2030 goals: "We do not rely on clients to tell us to design a high-performance building; we are going to do it anyway, it's our job."

Welcome to the quiz portion of Whole-Building Life Cycle Analysis: Promises and Pitfalls.
