Roland’s
Electric, Inc. has presented exciting hard data that shows how they
dramatically slashed their own existing commercial building’s energy usage and
expense by more than 70% with an energy efficiency installation, combining solar
and newly emerged LED lighting technology.
The impressive results can be easily duplicated in any existing commercial
building or applied to new construction.
Electricity consumption
at Roland’s headquarters is no different than you will find at other commercial
office, retail, and industrial buildings.
Lighting, computers, servers, monitors, printers, copiers, fax machines,
appliances, equipment, exterior lighting, and air-conditioning are in constant high-use
for most of the day. In nearly every situation,
the depth of the savings realized by an energy efficiency upgrade can be
significant – case in point: Roland’s own monthly average electric bill
dropped from $2025 down to $523 per month, slashing their greenhouse gas
emission in the process. Hospitals,
municipalities, restaurants, schools, and manufacturers may benefit even
more.
Averaging
Roland’s Electric historical monthly data reveals a solid 77.9% monthly
reduction in Kilowatt Hours/KWH, a 73.6% monthly reduction in Kilowatt Demand
Factor/KD, and a 74.2% reduction in monthly electric expenses.
The decision to retrofit
Roland’s Electric corporate headquarters over the winter months was an easy one
for the large electrical contractor located in Deer Park, NY. Given their expertise and knowledge in the
field, LEED accreditation, and the newly emerged technological advances in LED
lighting, the time was right to take advantage of the commercial rebates and
tax incentives to offset a large portion of the cost while they are still available. Roland’s Electric started their two phase
conversion after conducting a Comprehensive
Energy Audit, one of the many services which they provide. Each phase was completed in a few days.
CASE STUDY:
Roland’s Electric occupies a 1970’s single story flat roof 22,000 square
foot brick building in an older industrial area - 18,000 sq ft warehouse and
4,000 sq ft office space with standard 2’ and 4’ fluorescent ballast lighting fixtures
in the drop ceilings, typical of what you would find in any commercial building.
Phase 1: SOLAR: Roland’s Electric’s Design & Build team
planned 19.1KW rooftop installation consisting of 78 solar photovoltaic (PV)
245 watt modules on a southern exposure, with about a 1170 sq ft footprint. (Note:
you can go larger for a bigger offset but the rebates may not apply or
be proportional – Roland’s can guide and assist with rebates). Installation by their own Electricians took
one week to complete in December 2010 causing no disruption to their daily
operation. Results were immediate, dropping the monthly bills more than 61% from
an average of $2025/month down to $757-$781/month.
Phase 2:
LED LIGHTING: After three years of solar success, Roland’s
Electric began the second half of the Design & Build team’s plan, earlier
in 2014. They replaced 54 standard 2x2’
and 49 standard 2x4’ fluorescent overhead fixtures in offices, conference
rooms, hallways, and common areas with new high efficiency LED fixtures. (Note: the highest efficiency benefits require
complete fixture replacement). Over
a dozen occupancy sensors were installed in offices and a few low traffic areas
to shut off lights when unoccupied, and the warehouse received 21 LED high bay
fixtures.
New advances in
LED lighting technology allowed the lighting conversion to boost the already
considerable energy savings of the solar PV system. Roland’s
Electric has averaged an additional 37% reduction in KWH, 32% less KWD, and 32%
lower electric expense.
The solar panels came
through Hurricane Sandy completely intact and operational due to expert
installation and the custom aluminum frame they constructed - at a precise 30° angle for maximum
solar benefit for their location. Proper
techniques for connections and mounting are critical to withstand the force of winds,
trees, and flying debris, and should always be done by an experienced
professional.
