ACTIVITY

11
Specification Development
Challenges
Rapidly changing technology; little standardization
Technology much more complex than luminaires
Standards (overlapping, competing, incomplete, yet-to-be developed)
Systems, not components
Control system performance depends on both control system & luminaire
Interoperability – how to address?

13
Specification Strategic
Approach
Less Restrictive, Flexible
• Do not try to pick winners at this stage of technology. Allow for
innovation.
Capability-based
• Define system capabilities important to objectives and develop
specification requirements for them
Educate To Influence
• Educate on desirable capabilities / features and identify products
that have them
14
Identify Products that comply
with Open, Mature Standards
Open, Mature Standards Definition
Standards which are developed by
recognized Standards Development
Organizations (SDO’s) or in Industry
Consortia, and describe hardware or
software design and/or performance
requirements. “Open” standards are
those that are available to all
manufacturers for use in developing
compliant
products.
“Mature”
standards have compliance testing
tools and processes, certified
products databases, and broad
manufacturer and market adoption.

“Energy” vs. “Non-Energy”
Requirements
• Specification contains technical requirements that
are not directly related to energy savings. (e.g. GUI,
Security)
• Why do care about non-energy requirements?
1. Customer satisfaction with their customers participating
in programs
2. Ensure reliable energy savings to their regulators
3. Address barriers that prevent their customers from
participating in programs and/or using technology
16
“Conceptual” Level Specification
• Specification does not contain detailed specification
language and requirements
• Why? Collect stakeholder input earlier in process
• This is complicated… we are looking for your ideas!
• Two or more iterations from “Conceptual” to “Final”
17
Interior Controls, Not Exterior
• Specification is for Interior Networked Controls only
• Exterior specification to be developed in future
18
“Required” vs. “Reported”
Capabilities

required to be on QPL,
but QPL will identify
whether products have
them
