Hello Community!

I often get asked about the application cases of annual vs. marginal emissions. Are you aware of an ASHRAE standard or journal article that concisely describes the use case for different CO2 eq. metrics? Has anyone reviewed ASHRAE Standard 240P: Evaluating Greenhouse Gas (GHG) and Carbon Emissions in Building Design,... Read more

We are attempting to use Tally on a couple projects and are wondering how others are using the tool in their design process. If any experienced users out there would be willing to have a brief phone conversation I would appreciate it. Thanks

Hi everyone,

We're hoping to do some building monitoring as part of Building Use Evaluations on our built work, starting with projects in East Africa, to ensure they are performing as intended and to keep supporting our partners. Ultimately we want to be able to log light, noise, temperature, humidity and CO2 concentration. This does not... Read more

Friends,

This is a personal note. My son was just diagnosed with Asthma. I’m started to wonder if it’s just coincidence that this corresponded with him starting kindergarten in a school where they clean with Chlorine bleach. I found substitutes for his small preschool and at home.  My understanding is that there’... Read more

Hi Gurus,

LMN is embarking on a 17-part series to explore a more comprehensive carbon metric via summaries of various topics with lots of link. This dovetails with many other efforts in the industry and will reference all the best stuff that we are aware of...such as MEP 2040, SE 2050, CLF stuff, Epic tool, CARE tool, Arch 2030... Read more

Hi all,

I wanted to reach out to fellow MEP energy modeling teams to assess everyone's experience with the new PCI calculation methodology in 2016. It was a substantial change in how we show savings on projects. Big changes can often come with un-intended consequences. I'm all for pushing to higher efficiency - just want to make sure we...

Hi Friends, 

I'm working on an SOP for construction waste management for LBC core and LBC materials petal projects and wanted to get your input on the comingled facility requirements. According to the guidelines, any waste that goes to a comingled facility must be a facility that has an average diversion rate of 80% or higher as a... Read more

The BuildingGreen Guide to Thermal Insulation provides detailed guidance on insulation products and practices, including recommendations on what insulation to use and what to avoid. It's a treasure trove of information for architects and designers, builders, and anyone who is actively considering the impact of insulation on the quality of your... Read more

Dear Gurus,

At Greenbuild this year I'll be discussing how statistics can lie (in the context of green building claims).  I'm collecting examples of this to prepare.  If any of you know of examples, please send them to me! 

Here are a few of the fun ways statistics might lie that I would be looking for: biased or too-small sample... Read more

Churn and renovations can disrupt occupants, release or introduce indoor pollutants, and increase the embodied footprint of a building.

BuildingGreen-Approved Partitions

Movable partition systems allow spaces to be easily reconfigured, reducing costs and environmental impact. BuildingGreen approves partitions and panels that have... Read more

Upon completing this course, participants will be able to:


 

1. Define hygrothermal pressure and explain what it requires of water, air, and thermal barriers in high-performance assemblies.
2. Explain... Read more

I am looking at having staff members take a materials course and deciding between Parsons Healthier Materials and AIA Materials Matter certificate programs. Does anyone have feedback on either? Bonus points if you know about both and can provide a direct comparison. Thanks!
