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.
Develop documentation customized for LEED submission—complete with LEED-related notes, callouts, and details—concurrently with the finalized construction documents.
Projects that use their own maintenance staff for regular cleaning of rollout entryway systems must provide a cleaning schedule and narrative along with their documentation.
Include credit requirements in all appropriate specification sections. Include the general requirements in Division 1 and others in specialties or furnishings (for the entryway systems) and HVAC (for filtration and other mechanical requirements).
For all spaces that may contain hazardous gas (such as garages, janitors' closets, and labs), calculate exhaust rates to confirm adequate negative pressurization. The pressurization requirements are:
an exhaust rate of 0.5 CFM/SF with a pressure differential in relation to surrounding spaces of at least 5 Pascals (Pa)—.02 inches on water gauge—on average;
and when doors are closed, 1 Pa—.004 inches on water gauge—at a minimum.
Specify high-quality equipment with a dependably long lifespan. That way leakage is minimized at those times that carry the greatest risks; when the equipment is being installed or decommissioned. (For information about the service life of different types of HVAC equipment, see the 2007 ASHRAE Applications Handbook—HVAC Applications. See Resources.)
Complete your documentation through LEED Online by providing the HVAC&R equipment type, manufacturer, model number, installation date, and refrigerant used; state whether the equipment is for the LEED project only or from a central plant.
