Some research projects SEMERGY: SEMANTIC WEB & ENERGY (2011 – 2015)

• Energy & Emission related issues & challenges. • Buildings play a large role. • International & national incentives to reduce energy consumption of buildings. (EU 2002, 2010)

Some research projects SEMERGY: SEMANTIC WEB & ENERGY • Small share of new buildings • Less than expected refurbishment rate • Only 60% of refurbishments are thermal retrofits Clients reluctance, caused by: • lack of market transparency • lack of information for clients. • Highly complex retrofit processes with sometimes disappointing results • Low confidence in involved stakeholders • Lack of qualification of stakeholders for energy-efficient retrofit. • Lack of sufficient funds/financing opportunities for thermal retrofit. (DENA 2013)  Information & Decision Support Appliances could help

Some research projects SEMERGY: SEMANTIC WEB & ENERGY • Early-stage performance assessment can drastically affect final performance of the building • Currently assessment tools are used for certification and labeling of the final product rather than to support design decisions • Less than 10% of the developed tools are targeted for architects and designers

Some research projects SEMERGY: SEMANTIC WEB & ENERGY SEMERGY: A web-based, semantically-enriched decision support and optimization environment for energy- and environmentally-friendly building planning and refurbishment. Strategic Approach: • Data acquisition: Majority of data available in the web (unstructured) From www via semantic web technologies („web of data“, „web of things“) Data includes building materials, elements, components, physical properties, prices, legal and administrative constraints, subsidies, climatic boundary conditions. Data filtering based on user-specifications • Comprehensive evaluation process: Simplified/normative calculation routines for building related energy consumption Dynamic thermal simulation Ecological footprint of used materials Investment cost Future implementation / other domains

Some research projects SEMERGY: SEMANTIC WEB & ENERGY Potential User Groups • Novice Users (Laymen)  quick and convenient guidance through building design and retrofit process • AEC-Professionals  early design evaluation, communication platform for architects & clients • Municipalities, Developers, Authorities with large building portfolios  strategic decision making on large scale Typical Use-Case

Some research projects: The EDEN project EDEN (2015 – 2016)

No… not the greenhouse of Nicolas Grimshaw in the UK (1995-2001) But… a research project on Energy Certificates

Some research projects EDEN (2015 – 2016) • Input Data Quality for Building Energy Certification • Project team: U. Pont, O. Proskurnina, M. Taheri, A. Kropf, B. Sommer, M. SommerNawara, G. Adam, A. Mahdavi • Two university departments: • Department of Building Physics and Building Ecology, TU Wien • Energy Design, University of Applied Arts, Vienna

Some research projects EDEN (2015 – 2016) • Status Quo: • (close to) every building requires an Energy Certificate • Existing buildings: lack of documentation (= input data) • Measuring… destructive, cost intensive • Default values (lack of appropriateness)

Project idea: • Examination of Uncertainties in Input Data of Energy Certificates Goals: • Identify sources of uncertainty • Impact on KPIs • Derivation of an input data documentation to circumvent problems

Some research projects EDEN (2015 – 2016) • Methodology Methodological steps (i) Comprehensive literature and data collection, including issuers' current data acquisition practices. (ii) Generation of a database of sample buildings (different size, age, usage, etc.). A set of these sample buildings is selected for in-depth examination of uncertainties regarding input data (case studies). (iii) Calculation of energy certificates for the selected case-study buildings. (iv) Identification of potential uncertainties in the input data and of these uncertainties. Parametric variation of the “uncertain” input parameters and impact sensitivity analysis (on Key Performance Indicators) (iv) Derivation of a comprehensive input data documentation (with special focus on the examined uncertainties.

Some research projects EDEN (2015 – 2016) • Categories of Uncertainties (i) urban context of the building (insolation, adiabatic components) (ii) Usage of the building (heated/unheated, zoning, internal gains) (iii) Thermal properties of building envelope (Layered constructions, default values) (iv) Glazing attributes and solar gains (frame/glazing ratio, g-values of windows) (v) HVAC systems of the building (vi) Insufficiently considered parts and components of the building envelope (geometry)
