THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Hot spots: they might sound like fun places to hang out and have a drink—but in green building, they’re actually a bad thing. Something you track down so you can get rid of it. Kind of like being an environmentalist bounty hunter.

Life-cycle assessment (LCA) is... Read more

Hello all,

I need future weather files for a project. We are looking at three years, 2050, 2075, and 2095 using two climate change scenarios, low emissions, and high emissions. I have seen ARUP's Weathershift site that uses RCP 8.5 and RCP 4.5. Are we assuming that 2.6 is not achievable? I would have used this as a low emissions scenario... Read more

Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

Acceptable regulations for... Read more

Hi all,

We are looking to study Passive House on a couple small multifamily projects. Our understanding is that WUFI Passive only integrates with SketchUp at this time. Our BIM manager has been trying to find an example of a firm that works in Revit and uses WUFI Passive, to point him in the right direction on workflow. I offered to ask... Read more

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

Hello all, 

Any Fitwel experts out there? I have a 30,000 sf boutique hotel + spa client who would like to certify under the Fitwel rating system but Fitwel folks are telling me that no scorecard is currently available to hotel clients (can't use mulit-tenant or resi, that a hotel scorecard is under development). Has anyone used Fitwel... Read more

Is LEED Online mind-numbingly slow today for anyone else? Or is it just me? I may give up and try again tomorrow. Frustrating as I was hoping to submit a final review today. :(

Hi everyone,

We're pitching a green wall to a client for a project in NYC and are looking for recommendations on systems/companies.  We've done them locally, but the company we've worked with only services the Boston area.  There are so many companies out there now that we'd rather go with one that's recommended.  Thanks in advance for...

My dear collegues,

As I'm sure is true for many of us, the events of the past weeks (months/years/decades...) have emphatically reinforced to me the need for a radical shift in how we meaningfully address JEDI in what we do. One (admittedly small) step I've been thinking about are the statements of reconciliation that have become more... Read more

Textiles have some of the worst environmental records of any product found in our buildings. Textile production uses a number of hazardous chemicals and pollutes water; and its environmental impacts often affect our most vulnerable populations.

BuildingGreen favors textiles made using fibers and manufacturing processes that have low... Read more
