How to Create Additional Energy Savings by Choosing the Right HVAC Air Filter

How to Create Additional Energy Savings by Choosing the Right HVAC Air Filter by Shane Tincher June 4, 2007

Most businesses today are focusing on energy use and how it can be conserved to save money. Wal-Mart, for example, recently committed millions of dollars on a plan to find ways to reduce energy by 30 percent in its stores. Another example is how many major colleges and universities in the U.S. now have $100 million (or more) energy budgets and dedicated staff/resources to a Department of Energy Management.

With regard to energy savings, HVAC systems are a key component and opportunity to save money. According to the U.S. Department of Energy (DOE), HVAC accounts for 40-60 percent of the energy used in U.S. commercial and residential buildings. Additionally, the DOE 2003 Buildings Energy Databook reports that these commercial and residential buildings account for 39 percent of total energy consumption in the U.S. With most of the concentration being on boiler and chiller plant improvements, building automation, electricity peak shaving, lighting, windows, water system conservation, and alternate energy sources, to name a few, an often overlooked energy conservation measure is choosing the best air filter for the HVAC system.

AIR FILTRATION AND RESISTANCE

Air filtration not only contributes to overall indoor environmental quality, but also greatly contributes to airflow resistance before the coil. If we know that air filtration prevents fouling of the coil, then we know that the importance of the right air filter in terms of efficiency (to protect the coil) and resistance will go a long way in improving the operational efficiency of the HVAC system, and substantially affecting energy consumption. While many organizations focus on filter price in an effort to decrease the budget, the more appropriate target may be to focus on filter performance in an effort to make a substantial impact on reducing the energy budget (a much larger percent of operating dollars). However, it seems largely misunderstood just exactly how air filtration can play a role in energy savings. A quantification of this impact quickly shows that the savings can be huge when choosing the right air filtration product.

The purpose of this comparison is to save energy dollars by evaluating the HVAC system with regard to energy use and air filtration. In the air filtration industry, we know that greater dust holding capacity and lower resistance equals longer filter life in the system. We also know that energy cost (and not the initial purchase price) is the real cost of air filtration. By choosing an air filter that utilizes technological advancements in the air filtration industry to increase or upgrade to a higher MERV-rated filter, lower the initial resistance, maintain current dust holding capacity, and increase the life of the filter in the system, we win in energy savings, indoor air quality, and overall money savings.


In the past, air filtration choices with higher efficiency meant greater HVAC system load. This is no longer the case due to new air filtration technology. If we use the LEED Rating System for Existing Buildings as an example, we know that the right air filtration choice can conquer two of its main goals ‹ improved indoor environmental quality and energy efficiency. Specific credits (points) are given for upgrades to MERV 13, 14, or 15 where possible (difficult previously due to existing pressure drop concerns). However, this is now possible thanks to new MERV 14 and 15 air filtration products with initial resistance less than even the previous MERV 11 style air filter! As mentioned above, an improvement to filtration efficiency, combined with less resistance to the supply air and cleaner coils downstream of the filter, equal greater and cleaner airflow that is also more energy efficient. In addition, other components of the HVAC system, such as fans, will see greater operating efficiency.

ENERGY SAVINGS CALCULATION

Table 1 compares a MERV 15 filter with a MERV 14 filter. Each filter has a distinctly different initial cost and resistance, but the same final resistance, system information, and energy cost. The impact that produces the energy savings results that we seek can be noted in the Energy Cost per Changeout ($) in the table below. Note that System A uses a new technology filter (Figure 1) that is made from high-strength, high-impact polystyrene plastic and incorporates adhesive separators; so it has no metal components in order to make it a lower cost to manufacture (thus, the lower end-user cost for higher MERV in comparison to the System B filter shown in Figure 2).

Very simply, System A using the higher efficiency filter offers the 13 percent savings noted above thanks to the lower initial resistance (0.35 in.wg vs. 0.64 in. wg) and lower overall energy consumption (3,174 kWh vs.3,671 kWh). While having a lower price helps, the real impact on savings comes from energy.

Additional indirect benefits of this project are that we understand our HVAC system better than before. We notice more areas for improvement, such as the need for caulking and sealing of ³air bypass² areas within the HVAC envelope. We also begin (or continue) to review the calibration of our HVAC controls, monitoring software, labor costs for maintenance, and commissioning documents (review if applicable). We are making a solid commitment to our company/customer with regard to understanding and being proactive about the impact of energy consumption on operating profit.
Finally, we build a benchmark for others (internal and external) as we ³carry the torch² in energy conservation and sustainability efforts.

KNOW YOUR SYSTEM ‹ CALCULATE THE SAVINGS POTENTIAL

There are many different choices in air filtration today when it comes to finding a MERV 14 or MERV 15 filter. The initial cost of these filters is not the most important element of evaluation. This article points out that when we examine the choices by comparing some basic quantification, the most important factor that will add substantial benefit to existing efforts to reduce energy is initial resistance. If the real cost of the life cycle of the filter is in energy (which we know it is), then a filter with a lower initial resistance will provide the greater benefit in terms of energy savings.
