11 SMARTNESS Smartness refers to the capability of a building or its systems to sense, interpret, communicate and actively respond in an efficient manner to the changing conditions, which are introduced by demands of the building occupant, the operation of technical building systems or the external environment (including energy grids).

12 New paradigms It is not only about energy efficiency of the buildings and their subsystems but also how these are - Connected to the (energy) grids - Controlled and mutually interacting - Improving the quality of life of occupants -

13 New paradigms and new products and business models Load shifting and shedding Local energy generation Local energy storage, including vehicle to home / grid Automatic diagnosis and maintenance prediction Optimised controllers. And combinations thereoff, e.g. model predictive control for optimal self-consumption

16 Interoperability as a prerequisite for true smartness without lock-in effects

17 The smart readiness indicator

18 Smart Readiness Indicator (SRI) A Smart Readiness Indicator (SRI) would give recognition for smarter building technologies and functionalities which enhance the energy efficiency and other pertinent performance characteristics of the building stock. It could be an incentive for the integration of cutting edge ICT-based solutions for energy efficiency into buildings, which can assist in creating more healthy and comfortable buildings with a lower energy use and carbon impact, and facilitate the integration of renewable energy systems.

19 Objectives of the SRI study Commissioned by the EC Directorate-General for Energy Technical support to feed decision process: Quantify and assess impacts of smart technologies in buildings Propose a harmonized methodology to calculate and present SRI of a building Compare policy options by an impact analysis

20 Smart readiness aspects in scope of the study 1 Readiness to adapt in response to the needs of the occupant and to empower building occupants by taking direct control of their energy consumption and/or generation e.g. Management of heating system based on occupancy sensors e.g. Dashboards displaying current and historical energy consumption

21 Smart readiness aspects in scope of the study 2 Readiness to facilitate maintenance and efficient operation of the building in a more automated and controlled manner e.g. Signal when systems need maintenance or repair; e.g. use of CO2 sensors to decide when to increase ventilation

22 Smart readiness aspects in scope of the study 3 Readiness to adapt in response to the situation of the energy grid e.g. Reduce power consumption when grid demand is high e.g. Provide smart electricity grid with data on available flexibility and future expected consumption

23 TASK 1 Catalogue of smart ready services TASK 2 Definition of smart ready indicator(s) TASK 4 EU Impact assessment Compiling services taxonomy and related properties Develop indicator and test on set of reference buildings Building stock analysis (bottom up approach starting from developing reference buildings) TASK 3 Stakeholder consultation

24 Mapping the smart services SRI INDICATOR 11 DOMAINS SERVICES each domain: 3 to 17 FUNCTIONALITY LEVELS each service: 2 to 5 IMPACT SCORES 8 impact categories

25 Task 1 provisionally defined 10 domains where SR technologies & services may be applied Heating Domestic Hot Water Cooling Mechanical ventilation Lighting Dynamic building envelope Energy Generation Demand Side Management Electric Vehicle Charging Monitoring and Control

26 Task 1 - Structural view on the concepts used

27 Task 1 - For each domain there is an array of services Table 1. Heating sub-services considered in SRI Task 1 Heating-1 Heating-1a Heating-1b Heating-1c Heating-1d Heating-1e Heating-1f Heating-1g Heating-2 Heating-2a Heating-2b Heating-2c Heating-2d Heating-2e Heat control - demand side Heat emission control Emission control for TABS (heating mode) Control of distribution network hot water temperature (supply or return) - Similar function can be applied to the control of direct electric heating networks Control of distribution pumps in networks Intermittent control of emission and/or distribution - One controller can control different rooms/zones having same occupancy patterns Thermal Energy Storage (TES) for building heating Building preheating control Control heat production facilities Heat generator control (for combustion and district heating) Heat generator control (for heat pumps) Sequencing of different heat generators Heat system control according to external signal (e.g. electricity tariff, gas pricing, load shedding signal etc.) Heat recovery control (e.g. excess heat from data centres)

28 Task 1-8 impact fields were provisionally defined Energy savings on site Flexibility for the grid and storage Self generation Comfort Convenience Health Maintenance & fault prediction Information to occupants Current scoring is highly tentative Aim is to assist in selecting the main services from the current longlist Note, this consciously excludes security, fire-safety & emergency lighting functions

29 In progress: methodological development Select smart services to be included e.g. energy savings, DR capabilities, IEQ, interoperability, Determine cardinal or ordinal smartness performance metric and ranking for service functionality levels e.g. cardinal data or overall ordinal ranking A D cfr. EN e.g. smart meter available: yes/no Values expected for each smartness technical feature to the specific service e.g. energy savings to be expected from specific type of BACS, based on available standards Multi-criteria assessment, potentially including weighting into aggregated indicator

30 Tentative first glimpse on potential assessment framework to derive an SRI SRI = A a + B b + C c + D d + E e + F f + G g + H h Where: A = the impact score (from 0 100) for Energy Savings on site B = the impact score (from 0 100) for Flexibility for the grid and storage C = the impact score (from 0 100) for Self-generation D = the impact score (from 0 100) for Comfort E = the impact score (from 0 100) for Convenience F = the impact score (from 0 100) for Health G = the impact score (from 0 100) for Maintenance and health prediction H = the impact score (from 0 100) for Information to occupants and: a to h are the associated impact weightings Can also and simultaneously weight scores by domains

31 Planning Study runs until end of July 2018 Stakeholder Meetings: 1. 7 June Dec 2017 (on invitation) 3. April 2018 (to be decided) Updates on
