EN 16309-2014 pdf download.Sustainability of construction works – Assessment of social performance of buildings – Calculation methodology.
5.1 General
The object of assessment shall be the building, its foundations and external works within the area of the building’s site (curtilage) and any temporary works associated with the building’s use or refurbishment.
If the assessment is restricted to a part of a building or if any relevant aspects are not addressed, this shall be documented, reported and reasons explained.
NOTE The building’s site is identified as the physical space of land occupied by and attached to the building. The perimeter used to characterise the site needs to be consistent with the definition and intended use of the budlng.
The object of assessment shall be described in terms of its location, physical and time dependent characteristics.
The functional equivalent [3.9j is a representation of the required technical characteristics and functionalities of the building. It is the means by which the characteristics of the building are rationalized into a minimum description of the object of assessment.
NOTE 1 The object of assessment (the designed solution or the existing building) needs to deal with many requirements (legal, client’s. etc.) that may be diverging from the functional equivalent and may offer functionalities that are not included in the functional equivalent or have technical performances that exceed the minimum levels as specified in the functional equivalent: see Figure 1.
NOTE 2 The technical characteristics and functionalities of the building are not only covered by the functional equivalent of the designed solution but can also be part of the aspects and performance indicators of this standard, e.g. thermal comfort, use of natural daylight, fire performance. In this standard, these characteristics are only addressed with respect to their social aspects.
Comparisons between the results of assessments of buildings or part of works- at design stage or whenever the results are used — shall only be made on the basis of their functional equivalency. This requires that the major functional requirements shall be described together with the intended use and the relevant specific technical requirements. This description allows the functional equivalency of different options and building types to be determined and forms the basis for transparent and reasonable comparison. If the assessment results based on different functional equivalents are used for comparisons, then the basis for comparison shall be made clear.
NOTE 3 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 unit of reference. The choice of the common reference unit for all buildings being compared depends on a specific requirement of a technical, functional, envwonmental, 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 assessments of environmental, social and economic performance in a sustainability assessment of the same object of assessment, the functional equivalent used in the assessments of the individual dimensions of sustainability shall be the same.
The client’s brief and regulations may provide information on these items. Where this is not the case, the assessment shall include the assumptions that are made, the scenarios and the sources of information used.
NOTE 4 Other specific requirements and exposure to dirnate and to other conditions from the immediate surroundings may be relevant for inclusion in the information on the functional equivalent.
Where no required service life is specified by the client or by regulation, the design life may be used. If the design life Is used (which can be longer than the required service life), it shall be stated how it is derived, e.g. determined on the basis of empirical, probabilistic or statistical data.
NOTE 5 Eurocodes and ISO 15686-1 provide guidance on determining the design life of the building,
5.3 Reference study period
Assessments are carried out on the basis of a chosen reference study period.
The default value for the reference study period shall be the required service life of the building. Any deviations from this shall be clearly stated and reasons explained.
The reference study period may differ from the required service life given for the object of assessment depending on the intended use of the assessment, or on regulatory requirements or national guidance. The aspects of social performance are assessed for each occurrence dunng the reference study period.
5.4 System boundaries
The system boundaries are determined by the building to be assessed and its site. For a new building, In this first generation of the standard, the system boundary shall include only the use stage of the life cycle (see Figure 4). For an existing building (or part thereof), the system boundary shall include only the remaining service life.
The assessment shall include aspects of the building-integrated technical system and building-related furniture, fixtures and fittings. The system boundary for the assessment shall exclude impacts and aspects of the appliances and furniture, fixtures and fittings that are not building-related.
The aspects relating to appliances and furniture, fixtures and fittings that are not building-related may be assessed separately. Where this is the case, these shall be recorded and reported separately.
NOTE 1 Appliances that are not building-related are domestic, commercial and industrial appliances and other non- building related goods, e.g. entertainment electronics, washing machines, refrigerators, cooking appliances, office electronics and appliances of industrial processes.
NOTE 2 Building-related furniture, fixtures and fittings, are products that are fixed to the building so that the dismantling of the product decreases the performance of the building and the dismantling or replacement of the product constitute construction operations.EN 16309-2014 pdf download.
