building

Holy Cross Energy, founded in 1939, is a not-for-profit rural electric cooperative providing electrical power to consumers across a Colorado service area ranging from Vail to Rifle and Glenwood Springs to Aspen.  Built in 1982, our Headquarters Office contains over 28,000 ft2 of office space, a computer data center, and a dispatch center.

 

As an electric utility and ENERGY STAR partner, Holy Cross has programs in place that encourage consumers to conserve energy and utilize energy efficiency measures.  We have found that it is not enough to simply promote energy efficiency to consumers; we also want to set an example through our own actions.  For this reason, we benchmarked our headquarters office building and earned the ENERGY STAR.

 

Our energy managers have made it their goal to not only assist consumers with improving energy efficiency, but also to provide educational awareness programs in their own facilities.  We carefully monitor energy use in all of our facilities and contract with EMC Engineers to help improve the performance of buildings.  EMC Engineers has provided an initial site survey, monitored the HVAC equipment, and assisted in identifying, implementing, and installing energy efficient practices and technologies that contributed to reducing energy use.

 

Lighting in the headquarters office was an important element of our energy performance upgrades.  T12 fluorescents lamps with magnetic ballasts were upgraded to T8s with electronic ballasts and incandescent exit signs were upgraded to LED models.  Occupancy sensors also were installed to turn off lights in offices when they are empty.

 

We also have improved our building operation by programming start and stop times and temperature set-points for equipment to optimize energy efficiency and cost savings.  The heating system consists of three electric boilers serving perimeter radiation heating units.  Manual thermostatic valves on each unit allow occupants to control their individual comfort level, rather than having a single setting for the entire building.  We schedule the boilers so that one is energized early in the heating season and a second is brought on-line as winter weather settles in.  We use the third boiler for backup purposes, but rotate the units to allow for maintenance and balance wear and tear on the equipment.  To the extent possible, we also run equipment during off-peak hours to avoid peak demand charges.  This generates additional energy cost savings without compromising building comfort.

 

A 50-ton reciprocating water chiller, remote air cooled condenser, and a five horsepower chilled water pump make up our cooling system, which typically runs from mid-May to mid-September.  During the winter months when the chiller is off, the air handling units (AHUs) economizer controls modulate outside air (OA) dampers to maintain a 72 ?F space temperature.  During the summer months when the chiller is enabled, the AHUs economizer controls operate in a similar manner, but are locked out at 70 ?F OA temperature, meaning above 70 ?F the OA dampers will go to their minimum position.

 

All of the HVAC equipment is kept in optimal working condition with a preventative maintenance program that inspects and tests equipment on a regular basis.  Other equipment, like lighting, is also periodically inspected and replaced with more energy efficient products when economically practical.

Communications:

Holy Cross holds periodic staff meetings which provide a venue for updating management on the energy performance of facilities.  An in-house employee newsletter also is used to communicate this information with all staff.  Successes in energy management and conservation, as well as other ENERGY STAR information, are conveyed to consumers through a separate newsletter that is published three times a year.

Testimonial:

"Holy Cross Energy is a consumer-owned not-for-profit rural electric cooperative.  We are committed to providing our consumers with cost-effective electric energy and help them use that energy in an efficient, environmentally-friendly manner.  Our partnership with EPA through its ENERGY STAR program provides us with additional tools to reduce our own energy use and better assist our consumers."
