Enhancing energy performance certificates with energy related data to support decision making for building retrofitting

Abstract

The increasing availability of large-scale repositories of energy performance certificates offers the opportunity to interlink them with other data sources (cadastre, geographical data, weather data, building regulations, catalogues of refurbishment measures) and to derive innovative services that use the integrated data in conjunction with various tools (energy performance simulation, environmental impact). In the ENERSI project, two applications have been developed to make it easier for building owners and planners to take informed decisions to improve building energy performance in their properties and in their municipalities. These applications, named ENERHAT and ENERPAT, are based on the integration of building data from multiple sources and domains (energy performance certificates, cadastre, geographic information, and census), building refurbishment policies and assessment tools. Data integration has been performed using Semantic Web technologies. A user-friendly interface enables end-users of these on-line applications to obtain information about the current building status of properties, the measures which could be undertaken to improve them, the energy savings achieved and their respective costs.

A Comparative Study on Discrepancies in Residential Building Energy Performance Certification in a Mediterranean Context

“…EPC serves as a valuable global tool, providing engineers and consumers with insights into building energy performance and strategies for cost-effective enhancements [55,72]. A plethora of studies utilizing EPC software tools have concentrated on improving building energy performance through diverse scenarios, comparing and evaluating data derived from EPC [55,67,73,74]. Furthermore, certain studies have scrutinized EPC methods by juxtaposing measured and calculated energy ratings [75][76][77].…”

Arazi Yönetimi Paradigması Çerçevesinde Türkiye’de Binalar için Enerji Kimlik Belgesi Uygulamasının Değerlendirilmesi

Yapı sektörünün, Avrupa Birliği'nde nihai enerji tüketiminin ve toplam CO2 emisyonunun artmasında ciddi bir sorumluluğu olduğu bilinmektedir.…”

“…Avrupa Birliği ülkelerindeki mevcut binaların enerji tüketiminin yaklaşık %40'ından ve toplam CO2 emisyonunun %36'sından sorumlu olduğu bilinmektedir [1]. Son yirmi yılda, Avrupa Birliği'nde özellikle konut binalarına ilişkin enerji verimliliği politikaları geliştirilmekte ve çeşitli yasal düzenlemeler yürürlüğe konmaktadır.…”

“…Bu nedenle, çeşitli veri setleri ile bütünleşik EKB bilgilerinin kullanıldığı "Bina Enerji Bilgi Sisteminin" kurulması etkin enerji verimliliği politikalarının oluşturulmasında kritik bir öneme sahiptir. CBS uygulamaları sayesinde yerel yönetimler, bina stokları hakkında konum bazlı enerji performans verilerine sahip olmakta ve mevcut binaların rehabilitasyon olanaklarını ve finansmanını tanımlayabilmektedir [1].…”

Analysis of Energy Retrofit Assessment Methodologies in Buildings by European Research Projects

“…Another type of project is the development of an Energetic Action Plan for cities, the projects REPICATE [18], [19], GrowSmarter [20], ReemoUrban [35], and STEEP [22], [23]; they follow a similar schedule with three main working areas one of them being the improvement of energy efficiency of existing buildings. Tool development research projects also have been analysed, focusing on different working areas and systems, but all of them based on the use of a software to attend energy retrofit renovation projects, like OptEEmAL [24], [25], based on different energy conservation measures in to perform the energy use at building and district scale; EASEE [26], [27] focused on innovative envelope solutions; Paradis [28], [29], which generates and assesses optimal renovation scenarios; and ENERSI [30], a multi-disciplinary data management tool.…”
