Includes single products that serve multiple end-uses (e.g. HP serving DHW and HVAC, perhaps with integrated thermal storage), BMS controls that integrate control between multiple end uses (e.g. networked lighting sensors used for lighting and HVAC control), and integrated packages of measures (e.g. electrification packages with measures to improve envelope and reduce loads to a heat-pump HVAC retrofit OR integrated design that provides multiple services/benefits from each component such TABS embedded radiant floor panels, or broadly GEBs: Grid Interactive Efficient Buildings)
Multifunction Equipment, Integrated Controls, Integrated or Interactive Measure Packages
Integrated Systems have potential to bring large performance improvements beyond that of individual components or individual systems. Certain applications have the potential to reduce barriers and costs by providing electrification of multiple systems that can also result in large energy savings & improving demand flexibility (e.g. an integrated heat-pump system that combines water heating, thermal storage, space heating, and cooling).
Prospective ET projects should focus on development of efficiency measures or strategies that integrate multiple technologies that result in improved performance and/or reduced deployment costs.
Most performance improvements are component-based approaches addressing one piece of equipment or end-use at a time. Integrated systems can be significantly more complex, can span multiple building systems, and typically require a greater level of design, assessment, and more complex maintenance. For example, the CA eTRM database includes predominantly single technology or single or single end-use, resulting in most integrated systems solutions having to follow a custom-engineered approach.
Potential barriers studies should address:
- Lack of field performance data (including system reliability & cost-effectiveness)
- Lack of maturity of system testing & ratings.
- Lack of software tools to quickly assess performance of integrated systems.
- Lack of deployment infrastructure for integrated systems: need to better understand resources for designers, installers, and effective maintenance strategies.
