Teams can earn one point for installing and maintaining permanent entryway systems that meet the 10-foot length requirement. This strategy is typically straightforward and cost-effective for projects to achieve. However, it’s also fairly common for aesthetic considerations trump the benefits that entryway systems provide, so be sure to check with all relevant parties before counting on this point.

A number of additional strategies are offered under Option 2 (although you can only earn one point total under this option). The strategies outlined in the credit requirements can be achieved with varying degrees of difficulty, and some will likely be expensive to implement if you don’t already have compliant systems in place. Be sure to review and understand the requirements of each strategy (both the establishment and performance components) within the context of your building before committing to this option.

What’s New in LEED v4

• Portions of the following LEED 2009 credits have been combined into a single credit:  EQc1.2 Indoor Air Quality Best Management Practices—Outdoor Air Delivery Monitoring, EQc1.4: Indoor Air Quality Best Management Practices—Reduce Particulates in Air Distribution, and EQc3.5: Green Cleaning—Indoor Chemical and Pollutant Source Control.
• There is now additional guidance for warehouses, distribution centers, data centers, health care facilities, and residential projects.
• USGBC added additional options for naturally ventilated spaces.
• Teams have the option to use filtration media that meet CEN Standard EN 779–2002, Particulate Air Filters for General Ventilation, Determination of the Filtration Performance.

Readiness Review Questions

• Is your building already equipped with entryway systems? If not, can compliant systems be installed? What is the cost and timeline associated with installing new entryway systems or upgrading existing systems?
• Is your mechanical system compatible with MERV 13 filters? How will using MERV 13 filters impact the building’s energy use? Is there a cost premium for purchasing MERV 13 filters?
• Does your building have a history of problems with adequate outdoor air delivery, such as complaints of stale air, a “stuffy” feeling, or odors? If so, it would probably benefit from the use of monitoring devices and practices outlined by this credit.
• Does your building have variable ventilation loads due to changes in use from hour-to-hour or day-to-day? These types of buildings might see energy efficiency benefits from monitoring devices due to an increased ability to modulate loads.
• Does your building contain densely occupied spaces? If so, to what extent are these spaces equipped with CO2 monitors?
• Do you already use a BAS to manage HVAC in your building? If so, are you using sensors to monitor airflow rate and carbon dioxide concentration in occupied spaces?
