A building life cycle comprises four phases: conceptualize, design, construct, maintain and operate. Conceptualize: The phase in which the building is scoped and financed, conceptualization, consumes about 2 percent of the total costs of the building life cycle and marks the beginning and end of each building life cycle.Design: During the design phase, architects and engineers plan the detailed layout, structure, and execution of the building.Construct: In the construct phase the building is erected to its design specifications. Together, the design and construct phases account for some 23 percent of the total costs of the building life cycle.Maintain and Operate: The maintenance and operation phase represents the time during which the building is used, typically 25 to 30 years in today’s fast-moving environment—marked by its economic of functional life. It accounts for 75 percent or more of the total costs of the building life cycle.

Urban infrastructure in connection to sustainability issues

On the one hand, every community worldwide relies on the functioning of essential urban infrastructure like water, sewage and underground transport systems. Nearly every city region has to face the same problems of old infrastructural parts vulnerable to disturbances and in evident need of refurbishment and technical upgrade. On the other hand the building sector has been identified as a major contributor to environmental pollution. The sector accounts for about 40% of the total energy consumption of the world (WBSCD), which causes a severe environmental impact. Moreover 40% of raw material consumption of the world stems from the building industry (USGBC, 2004). Optimization of environmental impact during a building life cycle is a significant target in the context of sustainable development.
Integrating HBIM and Sustainability Certification: A Pilot Study Using GBC Historic Building Certification
Published in International Journal of Architectural Heritage, 2023

GBC Historic Building (GBC HB) Certification (by GBC Italia) is a protocol for evaluating sustainable heritage renovation, with the goal of preserving cultural value of the built asset while enhancing its environmental sustainability. The protocol is based on the LEED certification system (World Green Building Council 2016-2020) categories, adding one — Historic Value (Green Building Council Italy, 2020). The area of heritage conservation requires inclusion of a multidisciplinary team that should gather extensive knowledge in order to properly preserve the historic value that has been forming during a wide time span. In addition, the complexity of combining the fields of heritage redevelopment with environmental sustainability demands well-developed systems for information management. Building Information Modelling (BIM) offers an integrated approach for data handling (Historic England 2017), and is found to be a helpful tool for both topics. Its application for heritage management is commonly called Historic Building Information Modelling — HBIM (Dore and Murphy 2017; Ippolito 2017; Jordan-Palomar et al. 2018; Luggo et al. 2020; Oreni et al. 2014). Its integration in environmental design projects is proven to help in making informed decisions for any stage in building life-cycle (Wu 2010).
Assessing the life cycle performance of green building projects: a building performance score (BPS) model approach
Published in Architectural Engineering and Design Management, 2023

Three certified green buildings are considered for the study for model validation purposes. Amongst these, two are government office buildings (Case 1 and Case 2), and the other one is a corporate office and training center (Case 3) which are certified by LEED on their performance based on various factors considered for the assessment. The performance of these buildings in concern with sustainable construction is assessed at every stage of the building life cycle. Indicators chosen for the assessment process are evaluated by adopting qualitative and quantitative methods. Weightage for the indicators is evaluated by the AHP method, where a panel of six experts is chosen to obtain the weights. The importance of this model can be validated from the case study analysis and further discussion is made related to the study findings.
CIB - UTILITY BASED SYSTEMS FRAMEWORK FOR EXISTING RESIDENTIAL BUILDING

In this analysis, 17 macro-level sustainability assessment indicators were selected and divided into three main categories: community service facility (CSF); individual economy and service (IES); and building environmental planning (BEP). The three-pillar conception (social, economic, and environmental) of sustainability commonly represented by three intersecting circles with overall sustainability at the center is ubiquitous (Purvis, Mao, and Robinson 2019). The notion of building life-cycle design must be permeated with innovative thinking, also considering the equipment and facilities life cycle present in the overall indoor space, and products’ and services’ sustainable environmental attributes, including raw materials, energy, and recyclability. Meeting environmental goals, ensuring basic functions, service life, economy, and the quality of products and services must be paramount. Life cycle assessment (LCA) thinking is increasingly seen as a key concept for ensuring a transition toward more sustainable production and consumption patterns.
