This European Standard is part of a suite of European Standards, Technical Specifications and Technical Reports for the assessment of the environmental performance of buildings that together support quantification of the contribution of the assessed building to sustainable construction and sustainable development. The environmental performance of a building is only one aspect of its sustainability. The social and economic performance of the building are also aspects of sustainability that should be assessed as part of a sustainability assessment. These are described in the framework standards (EN 15643-1, -2, and
EN 15643-3, -4). NOTE The environmental assessment at building level requires information from products and services
(EN 15804). The evaluation of technical and functional performance is beyond the scope of this European Standard. Technical and functional characteristics are taken into account here by reference to the functional equivalent, which also forms a basis for comparison of the results of assessments. This European Standard is intended to support the decision-making process and documentation of the assessment of the environmental performance of a building. Although the assessment results are based on realistic scenarios, they may not fully reflect the actual and future performance of the building. Figure 1 illustrates how the assessment of the environmental performance takes place within the concept of the sustainability assessment of buildings.

RSP - Reference Study Period 5 The process for setting up the calculations required for the assessment In order to carry out and complete the calculations necessary for the assessment of environmental performance of buildings, the steps illustrated in Figure 3 shall be followed. This will help ensure that the essential information is gathered and processed according to the requirements of this European Standard. The clauses numbered in the right column that follow the diagram explain in more detail each step specified in the central column of the table below. SIST EN 15978:2011

7.1 General The object of assessment is the building, including its foundations and external works within the curtilage of the building’s site, over its life cycle. The curtilage used to characterise the site shall be consistent with the definition and intended use of the building. NOTE 1 The site is identified as the physical space of land occupied by and attached to the building. If the assessment is restricted to a part of a building or to an assembled system (part of works), or to a part of the life cycle, or if any relevant impacts or aspects are not addressed, this shall be documented, reported and reasons given. SIST EN 15978:2011
Figure 4 — Reference study period versus required service life of the assessed object Figure 4 illustrates the three cases: RSP 1: if the reference study period and required service life are the same, RSP/ReqSL = 1, the default value. RSP 2: if the reference study period is shorter than the required service life, the quantified values of impacts and aspects for the use stage (modules B1 - B7) and benefits and loads presented in module DB (see 7.4 and 8.8) that come from modules B1-B7, are adjusted by a factor RSP/ReqSL (see Figure 5). RSP 3: if the reference study period is longer than the required service life, scenarios for refurbishment, or demolition and construction of an equivalent new building shall be developed. These scenarios shall provide for an extension of the service life which, when combined with the required service life of the object of assessment, is equal to or more than the reference study period. The full value of impacts and aspects for both the actual required service life and the extension to the service life shall be taken into account following the rules given above. In all cases, the quantified values obtained for the product stage (modules A1, A2, A3, see Figure 6), the construction/process stage (modules A4, A5), and the end of life stage (modules C1 - C4) are independent of the value of the reference study period. The values for impacts and aspects for modules in the use stage (modules B1 - B7) are multiplied by the ratio of the reference study period to the required service life (RSP/ReqSL) as presented in figure 5. The loads and benefits reported in module D derived from the modules A (DA), B (DB) and C (DC) are also scaled in the same way. SIST EN 15978:2011
Figure 5 — Illustration of how the quantified impacts and aspects are adjusted for a reference study period that is less than the required service life (Case RSP 2) 7.4 System boundary 7.4.1 General The system boundary determines the processes that are taken into account for the object of assessment. For a new building, the system boundary shall include the building life cycle as shown in Figure 6. For an existing building (or part thereof), the system boundary shall include all stages representing the remaining service life, and the end of life stage of the building.
In this context, the object of assessment is the building and its site. This includes all the upstream and downstream processes needed to establish and maintain the function(s) of the building, from the acquisition of SIST EN 15978:2011
The consideration of aspects and impacts of the manufacturing of capital goods (e.g. trucks, cranes, ) shall be in accordance with Clause 9.4.3. 7.4.3.2 Boundary of the Transport to and from site (Module A4) The boundary for module A4 shall include: transport of materials and products from the factory gate to the building site, including any transport, intermediate storage and dist

SIST EN 15978:2011は、建築物の環境パフォーマンスを評価するための計算方法を定めた欧州標準です。この基準は、ライフサイクルアセスメント（LCA）に基づく計算法を規定し、環境情報を定量化して建物の持続可能性を評価するための手段を提供します。新築および既存の建物、改修プロジェクトにも適用可能であり、その適用範囲は非常に広いです。 この標準の強みは、建物のライフサイクル全段階をカバーしている点です。これにより、設計から施工、使用、廃棄に至るまで、あらゆる段階での環境影響を評価することができます。具体的には、評価対象の説明、建物レベルで適用されるシステム境界、インベントリ分析の手順、指標リスト、結果の報告やコミュニケーションの要求事項、計算に必要なデータ要件が提供されています。 また、評価において使用されるデータは、環境製品宣言（EPD）や関連情報モジュールから得られるため、確かなデータに基づいた客観的な評価が可能となります。このように、定量的な環境情報を用いることで、建物に関連するすべての建設製品、プロセス、サービスに対して、持続可能性を担保しつつ厳密な評価が行えます。 さらに、結果の解釈や価値判断はこの標準の適用範囲外であるため、評価結果を用いたさらなる分析や意思決定は、別の基準や方法に依存することになります。この点も考慮することで、より高度な評価が実現可能になります。 SIST EN 15978:2011は、持続可能な建築の実現に向けて非常に重要な役割を果たす標準であり、環境パフォーマンスの透明性と信頼性を高める手助けをしています。環境性能の評価を行う上での最も信頼できる指針として、多くの専門家に支持されていることから、この標準の重要性はますます高まっています。
SIST EN 15978:2011 표준은 건설 작업의 지속 가능성을 평가하는 데 중점을 두고 있으며, 건물의 환경 성능을 평가하기 위한 계산 방법을 제시합니다. 이 표준은 생애 주기 평가(LCA)와 기타 정량화된 환경 정보를 바탕으로 하여, 새로운 건물뿐만 아니라 기존 건물 및 리모델링 프로젝트에도 적용 가능하도록 설계되었습니다. 이 표준의 강점 중 하나는 평가 대상의 명확한 설명을 제공하고, 건물 수준에서 적용되는 시스템 경계를 정의하고 있다는 점입니다. 이러한 명확한 기준은 사용자가 평가 과정을 효율적으로 이해하고 적용할 수 있도록 돕습니다. 또한, 재고 분석을 위한 절차와 지표 리스트, 그리고 이러한 지표들의 계산 방법이 구체적으로 규정되어 있어, 일관되고 체계적인 평가를 가능하게 합니다. 보고 및 커뮤니케이션을 위한 결과 발표 요건이 포함되어 있어, 평가 결과를 명확하게 전달할 수 있는 방법론이 갖추어져 있습니다. 또한, 계산에 필요한 데이터의 요건을 명시하여, 신뢰할 수 있는 결과를 도출하는 데 필요한 정보를 확보할 수 있는 기초를 마련합니다. SIST EN 15978:2011의 접근 방식은 건물 생애 주기의 모든 단계를 포괄하며, 환경 제품 선언서(EPD)와 관련된 정보 모듈(예: prEN 15804)에서 얻은 데이터를 기반으로 합니다. 이는 전반적인 환경 성능 평가에 있어 필수적이며, 모든 건축 관련 제품, 프로세스 및 서비스가 포함됩니다. 이 표준은 진행하는 평가의 결과 해석이나 가치 판단을 포함하지 않기 때문에, 사용자에게 객관적이고 사실에 기반한 정보를 제공하며, 다양한 건축 프로젝트의 환경 성능을 성공적으로 평가할 수 있도록 지원합니다. 이러한 이유로 SIST EN 15978:2011은 지속 가능성 평가에 있어 중요한 기준으로 자리잡고 있으며, 건설 산업 내에서 그 의의와 효용성을 증명하고 있습니다.
The SIST EN 15978:2011 standard is a comprehensive framework for assessing the sustainability of construction works, specifically focusing on the environmental performance of buildings. The scope of this European Standard highlights its applicability to various types of projects, including new and existing buildings as well as refurbishment efforts. Its foundation is built upon Life Cycle Assessment (LCA) methodologies and leverages quantified environmental data to provide a structured approach to sustainability assessment. One of the significant strengths of the SIST EN 15978:2011 is its detailed specification of the calculation method required for accurate environmental performance evaluation. The standard meticulously outlines the object of assessment, ensuring that users have clarity on what aspects of the building are to be examined. Furthermore, the established system boundary at the building level aids in defining the limits within which the assessment is conducted, promoting consistency in evaluations. The procedural guidelines presented for inventory analysis are another highlight, making it easier for practitioners to gather and assess relevant data systematically. The inclusion of a comprehensive list of indicators and the specified procedures for calculating these metrics contribute significantly to the robustness of the assessment process, enabling stakeholders to gain a nuanced understanding of a building's environmental impact. Additionally, the standard emphasizes transparent communication by setting requirements for the presentation of results. This focus on reporting and communication ensures that findings of the environmental performance assessment are conveyed effectively to all relevant parties, enhancing accountability and informed decision-making. The likelihood of incorporating data from Environmental Product Declarations (EPD) and their “information modules” (as referenced in prEN 15804) allows for an inclusive assessment approach, covering a wide range of construction products, processes, and services throughout the entire life cycle of the building. This holistic view significantly strengthens the relevance of the SIST EN 15978:2011 standard in the context of ongoing sustainability discussions within the construction industry. It is important to note that while the standard provides a structured methodology for environmental performance assessment, it consciously excludes the interpretation and value judgments of the results, which can vary based on stakeholder perspectives. This aspect ensures that the standard remains technically grounded and focused strictly on quantitative analysis. Overall, the SIST EN 15978:2011 is a pivotal resource for professionals striving to enhance sustainability in construction through carefully designed assessment procedures.
