Hey team,

We're working with some institutions in the midwest that are trying to understand what kind of partnerships they could build with architectural salvage enterprises as they demolish many buildings to elevate land uses. I'm not overly familiar with the midwest market. Does anyone have any good circular economy / architectural... Read more

Hi Shane and Dennis,

What return address should we use for BIT User forum notification emails?  Ben suggests something like no-reply@bit-user.org but whatever you like is fine.

Once you decide, please let us know who controls the domain name (e.g. bit-user.org or bitbuilding.org).  Ben will send them instructions for editing the... Read more

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

I'm hoping for some help answering the question of whether buildings/communities should pursue net-zero energy on site versus investing in new renewable energy (i.e. through the electric utility) that can be built at a more efficient scale elsewhere in the state. Our utility is asking us this question as we are working through how to get the... Read more

I am looking for case studies/trying to identify buildings using concrete mixes with upwards of 30% replacement of cement by SCMs.  I've been in conversations with some structural engineers who are interested in lowering embodied carbon in upcoming projects, but would like to see examples of where this level of replacement has been successfully...

Show & Tell Breakout. Presentations:

Hi Everyone, just as governors are regionally deciding how to reopen their economies, it's probably time we started thinking about what getting back to work looks like for us.  And, just as governors are leaning on each other for ideas and coordination, we can benefit from discussing strategies as a group.  To that end, I wanted to get your...

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

Question for you all: there is this wonderful graph showing how we can shift mechanical and electrical dollars into envelope investments to make deep energy savings cost-neutral. Have you experienced this on a project?
