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?

Happy Friday, SDL!

We're running a Tally WBLCA for an environmental education center, which has a very small floor area but a fairly robust concrete/steel structure. Still, I was surprised to find an intensity of over 1,000 kgCO2/m2 for the building.

This is way higher than the general benchmarks I've found in the CLF's database,... Read more

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.

Hi,

I have a colleague doing research on PCM in several projects. For context in their report, they were wondering if this group has seen any recent increase in application of PCMs in recent years. Is it just in ceilings or other applications? If so, what products are being used? They were having difficulty finding manufacturers other... Read more
