Hi, working on a new school k-12 project with a chemistry lab. Does the 40 dBA background noise requirement need to be met concerning the fume hood?

LEED v4.1 If all products in one category comply with the VOC emissions evaluation do we need to list the cost or surface area?

We are having a tough time getting the costs from our subs. The subs says that the cost is bundled with other material and they can't break it up.

Hi All,

Has anyone come across a project that has multiple treatments on a wall (like an acoustic band), or multiple flooring finishes that are similar in shade / reflectance values?

I have a project located in an area without access to good construction waste recycling services and the best option is to haul waste more than two hours away from the site.

Table 7.8 DHW performance requirements for electric instantaneous water heater

NC-v4 EAc2:Optimize energy performance
posted by     on 

I see there is "Gas Instantaneous Water Heaters" in Table 7.8, but there is not an "Electric Instantaneous Water Heater" in the table.  Is the "Electric Water Heaters" term meant to be generic
