Industrial Projects
House
of Raeford
– Chicken processing – Identified over $120,000 in
energy savings with a Simple Payback of less than 4 months. Savings
were focused on chiller heat recovery, fuel and electric billing
savings, chilled water re-use, compressed air, and electric demand
control.
Austin
Quality Foods (Keebler) – Identified radio frequency oven
technology as a way to reduce energy cost, increase plant throughput,
and improve product quality. This technology was successfully installed
on multiple processing lines.
Southeastern
Container –
Worked with this manufacturer of plastic soda bottles to reduce energy
use and increase throughput of their pre-formed PET blow molding line.
In addition to energy savings, the results of the study enabled them to
defer purchase of a new $7,000,000 Sidel oven.
Guilford
Mills – Mr. Welch
conducted two in-plant test installations to demonstrate that IR
pre-heating of foam increases bond strength and reduces
variability in foam to fabric laminating. Mr. Welch assisted Guilford
Mills in the ensuing bid and purchase of a 100 kW IR pre-heater. Less
than a year later, they installed an identical IR pre-heater on another
laminating line.
Corning, Inc. – An
assessment provided this manufacturer of fiber optic cable with project
plans for over $800,000 in savings with an aggregate Simple Payback of
under 3 months.
Infrared Annealing
of Plastic - Testing by Mr. Welch showed a major plastics
manufacturer how IR heating can be used to anneal their plastic film
120 times faster than their hot air ovens. Energy consumption was
reduced by a factor of 20. The manufacturer installed this equipment
the next budget year, primarily justified by production rate increases.

Commercial and Institutional
Projects
City of Asheville,
NC
-
Worked with City of Asheville staff to identify over $150,000 per year
in energy cost reduction opportunities.
TIAA-CREF
– Corporate Campus – Over $66,000 per year in
energy savings identified, much of it in IT equipment. Mr. Welch
returned a year later to assist TIAA-CREF with certification of their
flag ship building as an ENERGY STAR labeled building.
Town
of Columbus,
NC - Identified the opportunity to reduce annual pumping
costs by over
$20,000 per year. This represents a 25% reduction in the Town’s
electric bill. The SCADA system to make this possible was installed
within six months.
RBC Center
- Sports Arena –
Worked with the RBC Center staff to identify $60,000 per year in energy
cost
reduction with a 1.4 month Simple Payback.
Lone Star
Restaurants – Conducted
investigations at seven locations and projected potential savings
across their entire portfolio of restaurants. Identified $1.3 million
in
Low Cost and No
Cost energy reduction measures. This represents 11% of their total
energy spend.

Utility Projects
Customer
and Staff Training – Mr. Welch is a
frequent trainer for utility staff and their Commercial and Industrial customers. Recent
training subjects include “Energy Efficiency 101 for Commercial
Buildings”, Preparation for the Certified Energy Manager exam, and
various process heating topics. Recently, these trainings have become
more web-based.
Duke Energy
Process Heating Program –
For almost 20 years, Duke Energy has provided their largest customers
with technical assistance and expertise in Process Heating. Much of the
work has been outsourced and Mr. Welch has served as the lead technical
resource for this work for more than a decade.
Central Maine
Power ESCO Validation – Over a three year
period, Mr. Welch served as the lead engineer and analyst in providing
M&V services to Central Maine Power’s Power
Partners program.
Power
Partners was an efficiency buyback program in which ESCOs
conducted performance contracting work and received partial
compensation from the utility based on actual achieved savings. Mr.
Welch served as the independent third party validating these savings.
