2 FM quick reads on ground operations
1. Improving Motor Efficiency
I'm Steve Schuster, associate editor of Maintenance Solutions magazine. Today's topic is motor efficiency.
Motors and the loads they drive represent some of the largest users of electricity in commercial and institutional facilities. Because motors are such high users of energy, they present a tremendous opportunity for maintenance and engineering managers to reduce energy use and cost through improved motor efficiency.
Much has happened recently that gives managers tools to improve motor efficiency. The federal government has developed energy standards that manufacturers must meet for the types of motors commonly found in a facility's energy-using systems. Replacing standard-efficiency motors with high-efficiency motors will reduce the energy requirements for that motor by about 2-8 percent. While that might not seem like a major improvement, depending on the horsepower of the motor and the number of hours it operates annually, the energy savings can be significant.
All of these energy-efficiency improvements come at a cost, however. The typical high-efficiency motor typically costs 10-15 percent more than the standard-efficiency motor it replaces. Premium-efficiency motors cost even more. But to help offset this increased cost and provide managers with the incentive to upgrade to more efficient motors, some utilities offer rebates and other incentives that can be as high as $50 per horsepower (hp).
Managers should evaluate their options based on the particular application. The amount of money they can save will depend not only on an improvement in operating efficiency but also on local utility rates and the annual number of hours of operation for that particular motor.
2. Bird Control Application Considerations
I'm Steve Schuster, associate editor of Maintenance Solutions magazine. Today's topic is bird control.
Few problems facing grounds managers in institutional facilities are as vexing — and potentially costly — as bird control. Birds come in a range of sizes, do varying degrees of damage to landscapes and facilities all year round, and can be maddening to truly control.
The rise of sustainability has added a layer of complexity to this challenge. In addition to weighing the cost and performance of any potential solution, managers also need to consider the product's impact on the birds and the larger environment.
Managers looking for strategies and products to control birds in and around their facilities must first consider the potential threat the birds pose to human health.
While health and safety get a great deal of attention in discussions of bird control, managers also know that birds can be a major threat to the buildings on their landscapes.
Such problems turn into major scheduling, workload and cost challenges for managers and their departments. The one element of bird control that managers probably gave little consideration to a decade ago is sustainability. Now, the impact of bird-control products on the environment is a high priority.
Given the evolution of products designed to address bird-control problems humanely, cost-effectively, and sustainably, managers should consider working closely with manufacturers to understand products' benefits and limitations and to ensure they specify the most effective product for their problem.
