Commitment to the Environment
Finish Curing Room
With the assistance of an outside consultant, a finish curing room was configured, tested and implemented in January 2010 in Nazareth. During the configuration the energy cost impact of the project was carefully considered. To minimize energy costs, several key features were incorporated into the project:
- A heat pipe energy recovery coil captures heat from the exhaust air stream and uses that heat to preheat the incoming outside air. The system can recover free heat on any day that the outside temperature is less than the room operating set point.
- Instrumentation monitors total VOC levels in the space on a continual basis. The ventilation airflow rate automatically modulates to maintain the tVOC levels at acceptable levels. This will allow for reduced ventilation rates and corresponding energy costs when tVOC emissions within the room are less than the design criteria.
- The system was designed to minimize air friction, thereby minimizing fan energy consumption.
- Motion controlled T5 high output (T5HO) lighting automatically turns off when the room is unoccupied.
Overall, the operation of the new finish curing room minimizes energy use. The energy recovery device within the finish curing room will save over 10,000 therms of natural gas per year, equating to more than 60 tons per year reduction in CO2 emissions.
In 2008 the roof covering the Martin Guitar finishing area was replaced with a new thermoplastic polyolefin (TPO) membrane. TPO membrane is energy efficient. Its white surface reflects the sunlight and reduces building cooling costs. TPO membranes are chlorine-free, and their heat-welded seams further contribute to the system's environmental friendliness.
By September 2009, 36% of the roof at Martin Guitar's 510 Sycamore Street facility was replaced using the same TPO membrane material.
From 2008-2009 lighting replacements were conducted throughout the Nazareth and Navojoa, Sonora, Mexico facilities.
- T5HO lighting contains 30% less phosphor than T8.
- T5HO lighting contains 70% less mercury than T8.
- Longer lamp life yields reduced maintenance costs and less going to the landfill.
- A T5HO lamp is a 5/8-inch diameter lamp, about 40 percent smaller than T12 lamps. The thinner lamps enable better photo-optic control of the light produced by the fixture, increasing efficiency, lowering energy costs and providing uniform distribution of its light output.
The wood acclimating room in Nazareth is equipped with a lighting control system and occupancy sensors so that lights automatically turn on when they are needed and turn off when the room is not occupied.
Based on specific starting and ending time assignments, a sophisticated building controls system automatically turns the lights off within Nazareth's sawmill, manufacturing and office areas when these areas are not occupied.
The lighting replacements throughout all Martin facilities are achieving nearly a 50% reduction in kilowatt hours (kwh) used.
Air Compressor Upgrades
In 2008 a variable frequency drive air compressor was installed at the Nazareth facility. This replaced the oldest of three original 150 hp air compressors. This compressor ties into the duct work above it, converting the exhaust air to heat for the Martin Guitar mechanical room during the winter months and hot water for heating office areas throughout the entire year.
A 50 hp variable frequency drive air compressor was installed at Martin's Navojoa, Sonora, Mexico manufacturing facility in 2005. This installation served as the prototype for the 150 hp version installed in Nazareth. A second 50 hp variable frequency drive air compressor is scheduled to be installed in Navojoa in Fall 2010.
In addition to its recycling efforts, the Information Systems Department continues to build upon an energy-efficient network for the Company. In 2008 the Department retired four physical servers and replaced them with virtual servers that not only take up less physical space but require less energy to run and less energy to cool.
