“…The framework incorporates another concept, demand flexibility (DF), which is consistent with recent literature on grid-interactive efficient buildings (GEB) (Eckman et al, 2019;Neukomm et al, 2019). Like DR, DF is characterized by active load management on timescales consistent with utility system and grid needs.…”

“…This framework is the first component of a broader research effort to assess the load impacts and economic relationships of EE and DR at the utility system level by developing an integrated valuation methodology based on EE and DR measure savings shapes and regional electricity features. 2 This is consistent with other definitions of EE in the literature (e.g.,York and Kushler, 2005;Goldman et al, 2010).3 See recent literature on grid-interactive efficient buildings (GEB)(Eckman et al, 2019;Neukomm et al, 2019).…”

Energy efficiency (EE) and demand response (DR) resources provide important utility system and ratepayer benefits. At the same time, the rapid change in the amount and type of variable renewable energy, like solar and wind, is reshaping the role and economic value of EE and DR, and will likely affect time-dependent valuation of EE and DR measures. Utilities are increasingly interested in integrating EE and DR measures and technologies (as well as other distributed energy resources) as a strategic approach to improve their collective cost-effectiveness and performance. However, the specific EE and DR features that may be best integrated, the interplay between changing EE and DR resource potential, and the resulting utility system impacts, are not well understood.

“…Cluster level interactions provide more opportunities in management of shared resources, such as DER, because of the potential for higher energy efficiency, aggregated load uniformity and more storage capability [112]. Also, integrating smart building technologies in a cluster of buildings benefits from economies of scale to reduce the investment and adaptation costs [113]. Therefore, the emergence of cluster interactions is shown in several cases such as Smart Neighborhood in Alabama, BedZED eco-community in London, Hammarby in Stockholm and Vauban in Freiburg [113,114].…”

Buildings are widely regarded as potential sources for demand flexibility. The flexibility of thermal and electric load in buildings is a result of their interactive nature and its impact on the building’s performance. In this paper, the interaction of a building with the three interaction counterparts of the physical environment, civil infrastructure networks and other buildings is investigated. The literature review presents a wide variety of pathways of interaction and their associated potential impacts on building performance metrics such as net energy use, emissions, occupant comfort and operational cost. It is demonstrated that all of these counterparts of interaction should be considered to harness the flexibility potential of the buildings while maintaining other buildings performance metrics at a desired level. Juxtaposed with the upside potential for providing demand flexibility, numerous implementation challenges are identified that are associated with the evaluation and financial valuation of the capacity for demand flexibility, the aggregated flexibility potential, as well as the control and communication to facilitate the interactions.

“…The framework focuses primarily on system impacts from the perspective of the utility or system operator. We consider the customer perspective, to a lesser extent, as part of assessing the change in the load that is available to provide demand flexibility (DF), defined as the capability associated with a building to modify energy consumption in response to utility grid needs [22]. We do not explore changes in customer economics (e.g., bill savings resulting in changes to payback period), customer perceptions of or attitudes towards EE or DR (e.g., through increased awareness of energy consumption patterns), broader policy issues of utility financial impacts (e.g., changes in utility collected revenues, achieved earnings, and achieved return-on-equity), or the alignment (or lack thereof) between program design and retail and wholesale market opportunities.…”

Energy efficiency (EE) and demand response (DR) resources provide important utility systems and ratepayer benefits. At the same time, the rapid change in the amount and type of variable renewable energy, like solar and wind, is reshaping the role and economic value of EE and DR, and will likely affect the time-dependent valuation of EE and DR measures. Utilities are increasingly interested in integrating EE and DR measures as a strategic approach to improve their collective cost-effectiveness and performance. We develop a framework to identify the EE and DR attributes, system conditions, and technological factors that are likely to drive interactions between EE and DR. We apply the framework to example measures with different technology specifics in the context of different utility system conditions. We find that EE and DR interactions are likely driven by changes in discretionary load, the addition of controls or other capabilities to shift loads, and the coincidence of savings with system peak or load building periods. Our analysis suggests increasing complexity in evaluating EE and DR interactions when moving from standalone equipment to integrated systems. The framework can be applied to research on integrated building systems by grouping measures into portfolios with different likely implications for EE and DR interactions.
