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

As if you weren't worrying enough already, here's a little something that I ran across through monitoring activity on the American Society of Healthcare Engineers discussion boards:  https://www.id-hub.com/2018/10/17/hospital-plumbing-reservoir-resistance-interview-amy-mathers/, "Hospital Plumbing as a Reservoir for Resistance".  This is both a...

Protection against corrosion is the primary function of steel coatings, which often contain corrosion inhibitors, volatile solvents, heavy metals, and other hazardous chemicals.

These coatings are specified when steel is used structurally, outdoors, or in high-use areas. In these situations, hazardous coatings are often applied off-site... Read more

It may take hundreds or thousands of years to return to pre-industrial-age levels of atmospheric carbon dioxide, but the loss of animal and plant species that is occurring today is, practically speaking, irreversible. It will take millions of years for evolution to fill the ecological niches being vacated by extinctions and restore healthy... Read more

Hi folks,

No details have been sorted out yet, but I wanted everyone to have a heads-up that the SCL Steering Group is proposing that we graduate to a full, stand-alone SCL Summit in 2020. (Until now we’ve been squeezing our Summit into the day before Greenbuild, which is good in some ways, but problematic in others—and limits our time... Read more

Have any of you relied on Green Badger for LEED documentation on projects?

I am familiar with the tool and know Tommy from my time in Atlanta, but have not used it on a construction project.

Have you found value? Thoughts?

Either way, they publish a pretty nifty "LEED v4 Construction Tool Kit" that may be useful for your... Read more

I have a client that is very interested in automated shades for a mid-rise multi-family housing project. Do you have any examples of projects that have attempted this? I assume it would involve occupancy sensors and/or an over-rideable default setting dependant on sun position and temperature. I also have an MEP Engineer team that is having a... Read more

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

Hey all,

We have a NAVFAC project going into construction that has indicated that they'd like to hire someone to help them with the construction tracking aspects of the UFC requirements, including the Guiding Principles Assessment (GPA) program through GBCI. We're on the design side, so cannot offer these services on our own project;... 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...
