Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

Hi all,

HOK has ~75 WELL APs whose credentials will expire in 6-12 months, so we're starting to look into a more robust CMP program.  Do you have great sources of health + wellbeing education, particularly WELL-specific CEUs, that you would recommend (emphasis on free or very low cost)?  We are currently using GBES, BuildingGreen, and...

Hi all,

We have a newly constructed, core/shell project having some hot water issues in the core restrooms.

There is a 0.35 Toto lav installed throughout. The hot water heaters are adjacent on each floor, located in the janitor closets. We did the math, and there could be a gallon of water standing and cooling in the pipe between... Read more

Hello Green Gurus,

Now is a pivotal moment. Net Zero Stretch Code legislation has been proposed in the Massachusetts House and Senate, and draft code language is currently being developed by the Board of Building Regulations and Standards (BBRS). The Net Zero Stretch Code is currently the greatest single opportunity to support reduced...

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Hello Everyone,

I'm looking for projects in Chicago that are exemplary in at least one of the following topics: Biophilia, Sustainability, Resilience, or Well-being. I know there is overlap in these topics but we're doing an internal design exercise and are looking at how these different ideas relate and are articulated in buildings. We'... Read more

Hi folks,

I know the last thing we all need is another assignment, but I took a look at this survey and it really should be pretty quick. And we've been talking a lot about how we can be better advocates for the things we care about...maybe this is a chance to do that? 

From an email request: 

I am writing on behalf of an... Read more

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

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

Hi, folks!

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
