SEMANCO Workshop Theme1 - Semanco

  1. 1. Modelling Energy Data in Urban EnvironmentsÁlvaro SiciliaARC Enginyeria i Arquitectura La SalleUniversitat Ramon Llull, BarcelonaMULTIPLE REPRESENTATIONS Barcelona, 11-12 April 2013
  2. 2. CONTENTSThe objective of SEMANCO is to provide methods and tools, based on semanticmodelling of energy information, to help different stakeholders involved in urbanplanning to make informed decisions about how to reduce CO2 emissions in citiesby:• Supporting access to and analysis of distributed and heterogeneous sources of energy related data• Modelling energy data according to standards of the Semantic Web• Providing integrated tools that access and update the semantically modeled data

  6. 6. INFORMAL – DISPERSED Energy data informally expressed and dispersed in different places and formats Use cases: Run energy performance analysis - To define the energy performance baseline of a City, Neighborhood, Tools requirements and Buildings. - To assess energy impact on new interventions (e.g. building Data sources needed refurbishment, new planning, new policies…) International Standards & References - International technical standards (e.g. EN ISO 13786 , EN 15193 , EN 15251, NREL/TP-550-38600, …) Terminology - Energy data modelling references (e.g. Tabula, Datamine, …) Energy data sources - GIS (e.g. Terrain images, 3D building models, Land registry, …) Terminology - Year of construction-based typologies (e.g. energy consumption, socio- economic, envelop properties, HVAC system, …) Data sources - Climate (e.g. temperature, solar radiance, …)
  7. 7. USE CASES METHODOLOGY Acronym UC10 Goal To calculate the energy consumption, CO2 emissions, costs and /or socio-economic benefits of an urban plan for a new or existing development. Super-use None case Sub-use case UC9A USE CASE Work process Users Planning  Municipal technical plannersspecification template  Public companies providing social housing providers  Policy Makers Actors  Neighbour’s association or individual neighbours: this goal is important for them to know the environmental and socio-economic implications of the different possibilities in the district or environment, mainly in refurbishment projects.  Mayor and municipal councillors: In order to evaluate CO2 emissions impact of different local regulations or taxes Related  Sustainable energy action plan (Covenant of Mayors) national/local  Local urban regulations (PGOUM, PERI, PE in Spain) policy  Technical code of edification and national energy code (CTE, Calener in Spain) framework Activities  A1.- Define different alternatives for urban planning and local regulations  A2.- Define systems and occupation (socio-economic) parameters for each alternative  A3. Determine the characteristics of the urban environment  A4. Determine the architectural characteristics of the buildings in the urban plans  A5. Model or measure the energy performance of the neighbourhood  A6. Calculate CO2 emissions and energy savings for each proposed intervention  A7. Calculate investment and maintenance costs for each proposed interventionUse cases and ACTIVITIESare connected creating atree
  8. 8. STANDARD TABLESStandard tables collect and classifies the information and knowledge from different sources:Use cases, Standards and data. - 24 categories including building use, climate, territory, socio-economic, and building geometry. - Each category contains terms and their relations (aggregation, subsumption) - Each term is referred to a specific Standard (EN 15603, TABULA,…), is typed (String, integer,…), and if it is applicable is measured (square meters, CO2 tons per year…) Name/Acronym Description Reference Type of data Unit construction as a whole, including its envelope and all technical building systems, for which energy is used to Building condition the indoor climate, to provide EN 15603 - - domestic hot water and illumination and other services related to the use of the building has Building_Name name (ID) of the building - string - has Age construction period of the building - string - is Year_Of_Construction year of construction of the building - string - period of years to be defined according to typical construction or building properties is Age_Class TABULA string - (materials, construction principles, building shape, ...) has From_Year first year of the age class TABULA string - has To_Year last year of the age class TABULA string - specification of the region the age class is has Allocation TABULA string - defined for has Identifier - SUMO A,B,C,D - has Address address of the building - string - first part of the postcode of the building has First_Part_Of_Postcode SAP string - location has Building_Typology building typology - string - is Flat apartment in a building - string - is Detached_Building small building, without attached buildings TABULA string - is Semi-Detached_Building small building, with an attached building TABULA string -

  10. 10. ONTOLOGYCodification of the Standard Tables into an Ontology - It is coded in OWL language (it can be seen as a XML file which can be processed by computers) - An Ontology is composed of two types of hierarchies: a) Subsumption (Taxonomy) b) Aggregation (Properties) - We have created an ontology editor which hide the complexity of ontology editing process. - 868 Concepts, 405 relations, and 278 properties a) Subsumption hierarchy b) Aggregation hierarchy FORMAL SHARED VOCABULARY

  15. 15. CONCLUSIONS SUMMARY• We have implemented a set of procedures, templates, methods, tools to conceptualize energy data in urban planning.• The energy related data –use cases, standards, data sources– have been represented in different ways from informally to formal format enabling their processing by computers.• An ontology including more than 800 concepts has been created modelling the energy- related data in the urban planning domain.• This way, different data sources from different domains could be integrated and could be accessed using the same terminology.
