Sustainability of Construction Works - Assessment of Buildings - Part 4: Framework for the assessment of economic performance

This European Standard provides the general principles and requirements, expressed through a suite of standards, for the assessment of buildings in terms of economic performance taking into account technical characteristics and functionality of a building. The economic assessment will quantify the contribution in economic terms of the assessed construction works to sustainable construction and sustainable development.
The framework applies to all types of buildings and it is relevant for the assessment of the economic performance of new buildings over their life cycle and of existing buildings over their remaining service life and end of life stage.
The economic performance assessment of a building addresses the life cycle costs and other economic aspects, all expressed through quantitative indicators. It excludes the economic risk assessment of a building and return on investment calculations
It includes economic aspects of a building relating to the built environment within the area of the building site, it does not include economic aspects beyond the area of the building site, e.g. such as economic impacts of construction of local infrastructure or economic impacts resulting from transportation of the users of the building or economic impacts of a construction project on local community.
NOTE 1   Assessment of economic performance is one aspect of sustainability assessment of buildings under the general framework of prEN 15643-1.
The standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods nor do they prescribe levels, classes or benchmarks for measuring performance.
NOTE 2   Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for economic performance in the client’s brief, building regulations, national standards, national codes of practice etc.
The rules for assessment of economic aspects of organizations are not included within this framework

Nachhaltigkeit von Bauwerken - Bewertung der Nachhaltigkeit von Gebäuden - Teil 4: Rahmenbedingungen für die Bewertung der ökonomischen Qualität

Diese Europäische Norm enthält
- in Form einer Normenreihe
- die allgemeinen Grundsätze und Anforderungen an die Bewertung der ökonomischen Qualität von Gebäuden unter Berücksichtigung der technischen Eigenschaften und Funktionalität eines Gebäudes. Mit der ökonomischen Nachhaltigkeits-bewertung wird der Beitrag gemessen, den die bewerteten Bauwerke unter ökonomischen Gesichtspunkten zu nachhaltigen Bauwerken und einer nachhaltigen Entwicklung leisten.
Die Rahmenbedingungen gelten für alle Arten von Gebäuden und sind bei der Bewertung der ökonomischen Qualität neuer Gebäude über deren gesamten Lebenszyklus und bei der Bewertung vorhandener Gebäude über deren restliche Nutzungsdauer und im Entsorgungsstadium maßgeblich.
Die Bewertung der ökonomischen Qualität eines Gebäudes befasst sich mit den Lebenszykluskosten und weiteren ökonomischen Aspekten, die alle mittels quantitativer Indikatoren angegeben werden. Sie schließt die wirtschaftliche Risikobewertung eines Gebäude sowie Renditeberechnungen aus.
In die Bewertung einbezogen sind ökonomische Aspekte eines Gebäudes, die sich auf die gebaute Umwelt innerhalb der Grundstücksfläche beziehen, davon ausgenommen sind ökonomische Aspekte, die über die Grundstücksfläche hinausgehen, z. B. ökonomische Auswirkungen auf den Bau der örtlichen Infrastruktur oder ökonomische Auswirkungen, die sich aus dem Transport der Nutzer des Gebäudes ergeben oder ökonomische Auswirkungen eines Bauprojektes auf die örtliche Gemeinschaft.
ANMERKUNG 1   Die Bewertung der ökonomischen Qualität ist ein Gesichtspunkt der Nachhaltigkeitsbewertung von Gebäuden innerhalb der allgemeinen Rahmenbedingungen nach prEN 15643 1.
Die unter diesen Rahmenbedingungen entwickelten Normen enthalten weder Regeln, wie die unterschiedlichen Verfahrensweisen der Beurteilung zu Bewertungsverfahren weiterentwickelt werden können, noch schreiben sie Grenzwerte, Klassen oder Richtwerte für die Bemessung der Qualität vor.

Contribution des ouvrages de construction au développement durable - Evaluation des bâtiments - Partie 4: Cadre pour l'évaluation de la performance économique

La présente Norme européenne présente les principes généraux et les exigences, sous la forme d'une série de normes, pour l'évaluation des bâtiments en termes de performances économiques, en prenant en compte les caractéristiques techniques et la fonctionnalité d'un bâtiment. L'évaluation économique quantifiera la contribution, en termes économiques, des ouvrages de construction au développement durable.
Le cadre méthodologique s'applique à tous les types de bâtiments. Il est valable pour l'évaluation des performances économiques de bâtiments neufs tout au long de leur cycle de vie, et de bâtiments existants pendant leur durée de vie restante et la phase de fin de vie.
La performance économique d'un bâtiment prend en considération les coûts survenant au cours du cycle de vie ainsi que d'autres aspects économiques, tous exprimés au moyen d'indicateurs quantitatifs. Elle exclut l'évaluation du risque économique du bâtiment et les calculs du retour sur investissement.
Elle inclut les aspects économiques d'un bâtiment relatifs au cadre bâti sur la parcelle, mais elle exclut les aspects économiques qui s'étendent au-delà de la parcelle, comme par exemple les impacts économiques de la construction d'une infrastructure locale ou les impacts économiques résultant du transport des usagers du bâtiment, voire les impacts économiques d'un projet de construction sur la collectivité locale.
NOTE 1   L'évaluation des performances économiques n'est qu'un aspect de l'évaluation de la contribution au développement durable des ouvrages de construction dans le cadre général du prEN 15643-1.
Les normes élaborées dans ce cadre méthodologique ne définissent pas les règles permettant d'établir comment les différentes méthodologies d'évaluation peuvent fournir des méthodes d'attribution de valeur et ne prescrivent pas de niveaux, classes ou référentiels de mesure des performances.

Trajnostnost gradbenih objektov - Ocenjevanje stavb - 4. del: Okvir za ocenjevanje ekonomskega učinka

Ta evropski standard je del skupine evropskih standardov za ocenjevanje stavb ter podaja posebna načela in zahteve za ocenjevanje ekonomskega učinka stavb z upoštevanjem tehničnih lastnosti in funkcionalnosti stavbe. Ocenjevanje ekonomskega učinka je eden od vidikov ocenjevanja trajnostnosti stavb v splošnem okviru standarda EN 15643-1. Okvir se uporablja za vse vrste stavb in je ustrezen za ocenjevanje ekonomskega učinka novih stavb v vseh fazah življenjskega cikla ter obstoječih stavb v preostali življenjski dobi. Ocenjevanje ekonomskega učinka stavb obravnava stroške življenjskega cikla in druge ekonomske vidike, izražene s količinskimi kazalniki. Ne vključuje ocene ekonomskega tveganja stavbe in donosnosti naložbe. Zajema ekonomske vidike stavbe v zvezi z grajenim okoljem na območju gradbišča ter ne zajema ekonomskih vidikov zunaj območja gradbišča, npr. ekonomskih vplivov gradnje lokalne infrastrukture ali ekonomskih vplivov zaradi prevoza uporabnikov stavbe ali ekonomskih vplivov gradbenega projekta na lokalno skupnost. Standardi iz tega okvira ne določajo pravil v zvezi s tem, kako lahko različne metodologije ocenjevanja zagotovijo metode vrednotenja, niti ne predpisujejo stopenj, razredov ali meril za merjenje učinka.

EN 15643-4:2012 (E) 4 Introduction This European Standard forms part of a series of European Standards, written by CEN/TC 350, that provide a system for the sustainability assessment of buildings using a life cycle approach. The sustainability assessment quantifies aspects and impacts to assess the environmental, social and economic performance of buildings using quantitative and qualitative indicators, both of which are measured without value judgments. The purpose of this series of standards is to enable comparability of the results of assessments. This series of European Standards does not set benchmarks or levels of performance. This series of standards will allow the sustainability assessment, i.e. the assessment of environmental, social and economic performance of a building, to be made concurrently and on an equal footing, on the basis of the same technical characteristics and functionality of the object of assessment. The sustainability assessment of buildings uses different types of information. The results of a sustainability assessment of a building provide values for the different types of indicators, the related building scenarios, and on the lifecycle stages included in the assessment. In carrying out assessments scenarios and a functional equivalent are determined at the building level Assessment at the building level means that the descriptive model of the building with the major technical and functional requirements has been defined in the client’s brief or in the regulations, as illustrated in Figure 1 below. Assessments can be undertaken for the whole building, for parts of the building which can be used separately, or for elements of the building. Although the evaluation of technical and functional performance is beyond the scope of this series of standards, the technical and functional characteristics are considered within this framework by reference to the functional equivalent. The functional equivalent takes into account the technical and functional requirements and forms the basis for comparisons of the results of the assessment. Any particular demands for, or related to, the environmental, social and economic performance defined in the client’s brief, or in regulations, may be declared and communicated. Figure 1 below shows how the functional equivalent, and the technical and functional characteristics that differ from those required, either by the client’s brief or through regulations, are to be declared and communicated with the results of the assessment.

NOTE The outer box with the dotted line represents the area to be standardised by CEN/TC 350. Figure 1 — Concept of sustainability assessment of buildings In concept, the integrated building performance incorporates environmental, social and economic performance as well the technical and functional performance, and these are intrinsically related to each other, as illustrated in Figure 2 below. Although the assessment of technical and functional performance does not form part of this series of standards, their interrelationship with environmental, social and economic performance is a prerequisite for an assessment of sustainability performance of buildings and, therefore, is taken into account. It is advisable to carry out an assessment at the earliest opportunity during the conceptual stages of a construction or refurbishment project such as in the sketch plan stage in order to provide a broad estimate of the environmental performance, social performance and economic performance. As the project evolves, the assessment may be periodically reviewed and updated to support decision-making. A final assessment (as built) should be carried out. The results of this final assessment can be used to inform all parties concerned. SIST EN 15643-4:2012

NOTE The darkened boxes represent the current work programme of CEN/TC 350. Figure 2 – Work programme of CEN/TC 350 This framework is Part 4 of the framework standards for sustainability assessment of buildings. The purpose of this EN 15643-4 is to provide a framework with principles, requirements and guidelines for the assessment of the economic performance of a building, as described at the "framework level" in above Figure 2.

The first revision of the general framework standard, EN 15643-1, is intended to combine all four parts of the standard into one framework standard. This will ensure simultaneous revision of the interlinked parts of the standard. In the future, the assessment methodologies within this framework standard may be part of an overall assessment of integrated building performance. The assessment methodologies may also be extended to an assessment of the neighbourhoods and wider built environment. SIST EN 15643-4:2012

EN 15643-4:2012 (E) 7 1 Scope This European Standard forms one part of a series of European Standards for the assessment of buildings and provides specific principles and requirements for the assessment of economic performance of buildings taking into account technical characteristics and functionality of a building. Assessment of economical performance is one aspect of sustainability assessment of buildings under the general framework of EN 15643-1.

The framework applies to all types of buildings and it is relevant for the assessment of the economic performance of new buildings over their life cycle, and of existing buildings over their remaining service life and end of life stage. The economic performance assessment of a building addresses the life cycle costs and other economic aspects, all expressed through quantitative indicators. It excludes the economic risk assessment of a building and return on investment calculations

It includes economic aspects of a building relating to the built environment within the area of the building site, it does not include economic aspects beyond the area of the building site, e.g. such as economic impacts of construction of local infrastructure or economic impacts resulting from transportation of the users of the building or economic impacts of a construction project on local community. The standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods nor do they prescribe levels, classes or benchmarks for measuring performance. NOTE Valuation methods, levels, classes or benchmarks may be prescribed in the requirements for economic performance in the client’s brief, building regulations, national standards, national codes of practice, building assessment and certification schemes, etc. The rules for assessment of economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the economic performance of the object of assessment are taken into account. 2 Normative references The following referenced documents are indispensable for the application of this document.
