Can We Replace Foam Insulation? – There are a lot of reasons to avoid foam, but its high performance can make it a hard habit to kick, as designers are finding out.
How WELL Got Green Building’s Groove Back – WELL is the hottest four-letter word in sustainable design. But will it work to the benefit or the detriment of green building?
20 Ways to Advance Sustainability in the Next Four Years – In this age of political revolution and environmental urgency, it’s time to step back and take a look at priorities, challenges, and opportunities. Here’s our founder Alex Wilson’s take on the best ways to advance sustainability.
Jobsite safety meetings or regular subcontractor meetings are a good place to educate your construction team about LEED requirements for IAQ management, as well as other related requirements for construction waste management, low-emitting materials, and other similar issues.
The requirements of this credit apply to all spaces within the building envelope. This credit does not differentiate between regularly occupied and non-regularly-occupied spaces.
Require that your contractor submit an IAQ Management Plan early in construction, before interior work has begun. The plan should detail the approach to this credit, as well as IEQc3.1 if both credits are being pursued.
Consider whether your HVAC system will be able to power a flush-out while maintaining temperature and humidity levels during seasonal extremes in a timely fashion, without major scheduling impacts. A total of 14,000 cubic feet of outside air must be exchanged for every square foot of floor area. The amount of outside air prescribed during a phased flush-out (0.3 CFM) may be several times greater than the normal rate required for a project’s occupancy, based on ASHRAE 62.1-2007, as required by IEQp1: Minimum IAQ Performance.
Many teams consider Option 1, but ultimately choose Option 2 for one of two practical reasons:
Scheduling the flush-out is not possible.
The building’s HVAC will not be able to maintain the required temperature and humidity levels for the duration of the flush-out. Doing so will also be energy-intensive.
If you follow the flush-out procedures required under Option 1, you will earn this credit, while if you follow the testing procedures under Option 2, you may earn the credit if your project passes the tests. This lack of certainty under Option 2 leads many project teams to pursue Option 1.
For projects with more than one main entrance, you may draw a circle from more than one entrance. The area contained within the circles drawn from all these radii is then used as your project’s radius.
