Hello,

This is not my area of expertise but our contactor has suggested central heat pump hot water (CHPHW) is $1m more expensive than gas fired domestic hot water for a 150 unit multi-family residential building in Massachusetts. The Building Decarbonization Practice Guide is extremely helpful but, from their comments, it is all coming... Read more

Hi MEP Leaders,

We had a great conversation in our last monthly call about the function and purpose of this group, and what we can best do together. You can see detailed notes from that call here. And we'll soon be sending out a reminder about the October call (Tuesday, Oct 8, 2pm eastern).

One of the ideas from that conversation... Read more

Older buildings—especially those from the 1950s, ’60s, and ’70s—need our help. Many leave something to be desired in terms of aesthetics and comfort. But the truth is that they are part of the urban and suburban fabric now, and they aren’t going anywhere. As tempting as it might seem to tear them all down and replace them with high-performance...

Hi SD Leaders: I'm hoping that you guys can be a great resource for a family member who teaches at Carnegie Mellon University, Professor Marvin Sirbu.

Returning to work: for many, it’s unthinkable without some kind of reassurance that leadership and the facilities team have taken all possible precautions. Lots of organizations are weighing in on what we should pay attention to, but how do we know if it’s working?

Hello everyone,

We are far too often asked to include parking in our buildings (because why shouldn't the average family have 2.1 kids, .8 pets, and 3 cars) and it always grates on me that we are putting so many resources (natural and monetary) into something that is almost certainly single use and will need to be demolished in 30 years...

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

Hi all,

I'm curious how various firms are approaching their own office projects, re green building certifications. I'm especially interested in medium-large firms that have multiple offices, but policies and processes from small firms may still be instructive.

Do you have a firm-wide policy or is it a case-by-case thing? Has... Read more

Hi Sages,

As you may have seen in my message, the Peer Networks Member List is not very helpful to us (yet), because a person can only show up in one network. Many of us are also in SDL or other networks; there are many more of us than show up when you filter that list for "Sages."

Until we can get that fixed, we'll share the... Read more

Early laminate flooring had problems with premature surface wear, moisture damage, and hazardous formaldehyde emissions—and some products may still have these problems.
