and addressable LED systems ability to produce savings via daylight harvesting and network controls.

Additionally, whole building network controls are becoming more prominent and cost effective, which

should move more customers in that direction.

5.4.2.2 Motivations and Barriers

Table 14 summarizes customer motivations and barriers as reported by PA respondents. The topics are

further explored in the sections below.

5.4.2.2.1 Customer Motivations and Barriers

Respondents were asked to address why lighting control retrofits were a challenge to large C&I

customers. One typical response was physical design restrictions of the facility structure prohibiting

retrofit upgrades from being effective. Unless the facility was directly owned by the customer and

undergoing a full facility renovation, installing hardwired and wireless network control technology was

cost prohibitive.

Utility customers were reported to have more awareness, knowledge, and enthusiasm about certain

lighting control technologies such as occupancy sensors and daylight dimming/occupancy sensors,

however PAs are seeing a widening gap between the educational awareness of earlier generation lighting

control measures and evolving technology. Several respondents commented that utility customers that are

early adopters of technology are more willing to adopt newer lighting control technology; whereas

customers that are slower to adopt newer technology, yet still enthusiastic, are observed to succumb to

technology stigmas such as; “not wanting to wave their arms around to turn the lights back on.”

Custom retrofit lighting control implementation proved to be a barrier for customers. Respondents

indicated that little effort was being made to explore lighting control opportunities through the custom

approach. Even if opportunities for custom lighting retrofit controls were identified by PAs, if vendors

were not knowledgeable, didn’t supply specific technologies, or were unfamiliar with installation

specifications, energy savings opportunities were lost.

Other areas for lost savings were identified as small retrofit upgrades where it didn’t seem cost effective

to hire a consultant to quantify the controls savings.

The PAs have identified that customer barriers do not always reside with the customer and that a further

gap in educational awareness resides with vendors, distributors and implementation contractors.

5.4.2.2.2 Vendor, Distributor, and Installation Contractor Motivations and Barriers

Lack of consistent training and education was a common theme among the PAs as they further identified

barriers with regards to retrofit lighting controls. Differences in vendor/customer relationship were

observed between the utility territories. Some administrators responded that program participants work

through Energy Service Companies (ESCO’s), other customers work with local area vendors and may not

be exposed to current lighting control technologies in the market place because the vendor may not offer

or endorse the technology.

Occasionally, vendors cannot provide a strong methodology on how to quantify energy savings and that

lighting control technology may be difficult to promote to utility customers and if large reductions are not

present it may not be worth the time of the vendor. According to respondents, additional energy savings

opportunities are gained or lost dependent on the vendor and their level of knowledge and experience.

This seems to be a great opportunity to help educate vendors, as savings estimates for this type of upgrade

are relatively simple.

5.4.3 Future Actions

Opportunities identified by respondents indicate that whole building, advanced lighting control retrofits

will become more of the norm as technology becomes more prominent in the market place and more

affordable. Currently, there is a steep slope when considering whole building, advanced lighting controls

† ASHRAE 90.1, the national model building code, is updated every three years and includes several
controls requirements in ASHRAE 90.1–2010 including automatic shutoff controls and photocells in
certain space types. However, states have until 2013 just to update their codes to meet ASHRAE 90.1–
2007, and some states still meet only ASHRAE 90.1–2001 (U.S. Department of Energy 2011a).
