Supporting the Smart Readiness Indicator—A Methodology to Integrate A Quantitative Assessment of the Load Shifting Potential of Smart Buildings

Abstract

With the third revision of the Energy Performance of Buildings Directive (EPBD) issued in July 2018, the assessment of buildings now has to include a Smart Readiness Indicator (SRI) to consider the fact that buildings must play an active role within the context of an intelligent energy system. In order to support the development of the SRI, this article describes a methodology for a simplified quantitative assessment of the load shifting potential of buildings. The aim of the methodology is to provide a numerical, model-based approach, which allows buildings to be categorized based on their energy storage capacity, load shifting potential and their subsequent interaction with the grid. A key aspect is the applicability within the Energy Performance Certificate (EPC) in order to provide an easy to use calculation, which is applied in addition to the already established energy efficiency, building services and renewable energy assessments. The developed methodology is being applied to theoretical use cases to validate the approach. The results show that a simplified model can provide an adequate framework for a quantitative assessment for the Smart Readiness Indicator.

Resilient cooling of buildings to protect against heat waves and power outages: Key concepts and definition

“…Different dynamic control strategies with predictive algorithms should be embedded in building operation systems using a deeply coupled network of sensors. The smart readiness of buildings is part of resilience because it considers the fact that buildings must play an active role within the context of an intelligent energy system [82].…”

“…The capacity of a building to use information and communication technologies and electronic systems to adapt its buildings services operation is essential. The same applies to adapt to the occupants' needs and the grid signals to improve indoor environmental quality during heat waves and power outages [82,87]. Finally, regional priorities regarding the climatic disruptions potential and investigate the possibility of passive resistance mechanisms of buildings (e.g., ventilative cooling and thermal storage technologies) and their adaptability robustness mechanisms should be addressed.…”

Smart Building Integration into a Smart City: Comparative Study of Real Estate Development

“…Design and construction stages are most relevant to adopting building information modelling (BIM) and geographic information system (GIS) technologies, which enable integration with 3D City model and all digital data provided by Internet of Things (IoT) sensors and big data centers, digital services, and procedures implemented by smart city government [16][17][18]. The most value from the smart building integration into the smart city is accounted for in the operation stage: digital twin and building maintenance system (BMS) integration into the city networks reduces the costs of operation by optimizing resource consumption and changing the overall RE concept from the asset to the service due to shared information within smart city networks [14,19,20].…”

Integrating Energy Demand and Local Renewable Energy Sources in Smart Urban Development Zones: New Options for Climate-Friendly Resilient Urban Planning

“…The new EPBD directive [57] requires an assessment of the potential of load shift in buildings in order to assess the Smart Readiness Indicator (SRI) of buildings, which shows the high importance of load shifts and storage management with regards to buildings. The load shift potential can also be assessed quantitatively [58]. 4.1.6.…”
