Sustainability of construction works - Assessment of buildings - Part 4: Framework for the assessment of economic performance

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.

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

Diese Europäische Norm ist Teil einer Reihe Europäischer Normen für die Bewertung von Gebäuden und enthält die spezifischen Grundsätze und Anforderungen an die Bewertung der ökonomischen Qualität von Gebäuden unter Berücksichtigung der technischen Eigenschaften und Funktionalität des jeweiligen Gebäudes. Die Bewertung der ökonomischen Qualität ist ein Aspekt der Nachhaltigkeitsbewertung von Gebäuden im Kontext der allgemeinen Rahmenbedingungen von EN 15643-1.
Die Rahmenbedingungen gelten für alle Arten von Gebäuden und sind für die Bewertung der ökonomischen Qualität von neuen Gebäuden über alle Phasen des Lebenszyklus und von bestehenden Gebäuden bis zur Entsorgung maßgeblich.
Die Bewertung der ökonomischen Qualität eines Gebäudes befasst sich mit den Lebenszykluskosten und weiteren ökonomischen Aspekten, die alle mittels quantitativer Indikatoren angegeben werden. Die wirtschaftliche Risikobewertung von Gebäuden sowie Renditeberechnungen sind nicht Gegenstand der Bewertung.
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, ökonomische Auswirkungen, die sich aus dem Transport der Nutzer des Gebäudes ergeben, oder ökonomische Auswirkungen eines Bauprojektes auf die örtliche Gemeinschaft.
Die unter diesen Rahmenbedingungen entwickelten Normen enthalten weder Regeln, wie die unterschied¬lichen Verfahrensweisen der Bewertung zu Bewertungsverfahren weiterentwickelt werden können, noch schreiben sie Grenzwerte, Klassen oder Richtwerte für die Bemessung der Qualität vor.
ANMERKUNG 1   Bewertungsverfahren, Grenzwerte, Klassen oder Richtwerte können in den umweltbezogenen, sozialen und ökonomischen Qualitäts¬anforderungen des Lastenheftes des Auftraggebers, in gesetzlichen Vorgaben im Bauwesen, nationalen Normen, nationalen Verfahrensregeln sowie in Systemen zur Bewertung von Gebäuden und zur Zertifizierung usw. vorgeschrieben werden.
Die Regeln zur Bewertung der ökonomischen Aspekte von Organisationen sind in diesem Rahmenwerk nicht enthalten. Die Folgen von Entscheidungen oder Maßnahmen, die die ökonomische Qualität des bewerteten Gegenstandes beeinflussen, werden jedoch berücksichtigt.

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 fait partie d'une série de Normes européennes relatives à l'évaluation des bâtiments et fournit les principes et exigences spécifiques pour l'évaluation de la performance économique des bâtiments, en tenant compte des caractéristiques techniques et de la fonctionnalité du bâtiment. L'évaluation de la performance économique n'est qu'un aspect de l'évaluation de la contribution des bâtiments au développement durable dans le cadre général de l'EN 15643-1.  
Le cadre méthodologique s'applique à tous les types de bâtiments. Il est valable pour l'évaluation de la performance économique 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.
L'évaluation de 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 de 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.
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.
NOTE   Les méthodes, niveaux, classes ou référentiels d'attribution de valeur peuvent être prescrits dans les exigences relatives à la performance économique contenues dans le programme du maître d'ouvrage, les règlementations du secteur du bâtiment, les normes nationales, les codes de bonne pratique nationaux, les systèmes d'évaluation et de certification des bâtiments, etc.
Les règles pour l'évaluation des aspects économiques des organisations ne sont pas incluses dans ce cadre méthodologique. En revanche, les conséquences des décisions ou des actions qui impactent la performance économique de l'objet de l'évaluation sont prises en compte.

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.

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

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.

 to identify the economic aspects and impacts of the building and its site,  to enable the client, user and designer to make decisions and choices that will help to address the need for sustainability of buildings. 4.3 Approach to assessment of economic performance According to the general principles of sustainability in building construction described in ISO 15392, all three dimensions of sustainability of buildings (environmental, social and economic) are necessary elements in a systemic approach to a sustainable assessment. Statements on the sustainability performance of a building shall address all three dimensions. This implies that when dealing with the sustainability assessment of a SIST EN 15643-4:2012

The aspects and impacts of a building that relate to its economical performance are influenced by actions taken throughout the entire life cycle of the building.
5 Requirements for assessment methods 5.1 General The assessment methods within this framework shall (as far as possible) ensure that double counting of performance aspects and impacts is avoided. SIST EN 15643-4:2012

NOTE 4 Furniture, fixtures and fittings that are not building-related are products that are not fixed to the building, so that the dismantling of the product has no impact on the performance of the building and the dismantling or replacement of the product does not constitute construction operations. NOTE 5 Sensitivity analysis can be used to describe the potential influence of the non-assessed aspects. 5.3 Functional equivalent — Requirements for basis for comparability Comparisons between the results of assessments of buildings or assembled systems (part of works) - at design stage or whenever the results are used – shall only be made on the basis of their functional equivalence. This requires that the major functional requirements shall be described together with intended use and the relevant specific technical requirements. This description allows the functional equivalence of different options and building types to be determined and forms the basis for transparent and reasonable comparison. If assessment results based on different functional equivalents are used for comparisons, the basis and conditions for this comparison shall be made clear. NOTE 1 If appropriate, the assessment results of the buildings that have different functional equivalents (e.g. design options for different types of buildings on the same site or the same types of buildings exposed to different conditions) can also be compared based on a common reference unit. The choice of the common reference unit for all buildings being compared depends on a specific requirement of a technical, functional, environmental, social or economic aspect, or combination thereof, which is common to all these buildings and is linked to their corresponding functional equivalents. When combining separate assessment of environmental, social and economic performance for sustainability assessment the same functional equivalent shall be used for the assessment of each of the individual dimensions of sustainability.
