To minimize problems with pressure drop, look for filters that have a low initial resistance to airflow. Generally, the lower the initial resistance to airflow, the lower the energy use. This information can be found on product cut sheets.

Some buildings have incompatible mechanical systems. This stems from both a lack of available products that physically fit in filter housings and increased resistance to airflow, known as “pressure drop.” A MERV 13 filter’s high level of filtration removes more contaminants than traditional media, but also creates more resistance to air moving through it. Because of this, the equipment works harder and uses more energy to move the same volume of air. Some systems can’t provide the added power required to move the minimum airflow needed.

MERV ratings are measured by ASHRAE Standard 52.2 and range from 1–16, rating the filter’s ability to remove small particulates in the ventilation system. Sixteen is the highest level of filtration available as measured by ASHRAE 52.2.

If concerned about costs, do a payback analysis. Although some efficient fixtures cost more than typical ones, efficient fixtures significantly reduce energy use and operating costs and often have a payback of 1–3 years. Consider this payback analysis before eliminating any installed lighting power reduction strategies from the final construction plan. 

Reduce energy use with lighting controls such as daylight sensors, occupancy sensors, nighttime setbacks, and dimmers, even though they don’t reduce lighting power and won’t help for this credit.

Be aware that in ASHRAE 90.1-2007, the lighting power is the maximum wattage of the light fixture and does not include lamp-ballast or lamp-transformer combinations, as was the case with older standards.
