“…This study differentiates from other studies of cost optimal strategies for stakeholders in the following aspects. The researched studies [26][27][28][29] did not include thorough life cycle costs and mostly considered energy supply costs over the lifetime as LCC. Some of them [26] approached operational costs as a sum of energy consumption over the lifetime with a static calculation method that does not include inflation or interest rates.…”

“…However, the past efforts do not combine VfM and LCC assessment in a comprehensive way. A range of authors, such as Lee et al [26], Hasan et al [27], Leckner and Zmeureanu [28], and Matic et al [29] partly use either the LCC or operational costs parameters. Lee et al incorporate heating and cooling costs including the energy cost inflation.…”

This paper proposes an extended comparative evaluation model framework (ECEMF) that highlights two objectives: (1) a specific economic evaluation method for the cost-optimisation of prefabricated lightweight system envelopes to achieve a greater value of the building, and (2) a comparative evaluation model framework usable by different profiles of stakeholders, when adopting the decision on the most optimal envelope type in the early design phase. Based on the proposed framework, the analysis was conducted for the case study building representing a small single-family house located in Slovenia. The methodology applied is based on the life cycle cost (LCC) including construction, operation, maintenance, and refurbishment costs, but excluding dismantling, disposal, and reuse, for the period of 50 years’ lifetime of the building which combines the Building Information Modelling (BIM) with Value for Money (VfM) assessment. To exploit the automated evaluation process in the computing environment, several tools were used, including Archicad for BIM in combination with Legep software for LCC. On one hand, the model confirms the assumption that the optimal value parameters of a building do not only depend on the typical costs related to high-performance buildings. On the other hand, from the stakeholders’ view, the model enables the choice of the optimal solution regarding the envelope type to be made in the early design phase. In this view, the model could function as an important decision tool, with a direct economic impact on the value.

“…In addition, it is not possible to draw any comparisons among the perivios LCA studies and find generalisable design principles that could be employed by designers at the early design stage. It was identified through the review of some LCA studies of building materials and products due to use of different assumptions, materials, databases and analysis method (Asif, Muneer, & Kelley, 2007;Bribián, Capilla, & Usón, 2011;Crawford, 2013;Dodoo, Gustavsson, & Sathre, 2014;Kofoworola & Gheewala, 2008;Lee, Kim, & Na, 2015;Monahan & Powell, 2011;Monteiro & Freire, 2012;Thiel et al, 2013).…”

Life Cycle Assessment (LCA), developed over 30 years ago, has been helpful in addressing a growing concern about the direct and indirect environmental impact of buildings over their lifetime. However, lack of reliable, available, comparable and consistent information on the life cycle environmental performance of buildings makes it very difficult for architects and engineers to apply this method in the early stages of building design when the most important decisions in relation to a building’s environmental impact are made. The LCA quantification method with need of employing complex tools and an enormous amount of data is unfeasible for small or individual building projects. This study discusses the possibility of the development of a tool that allows building designers to more easily apply the logic of LCA at the early design stage. Minimising data requirements and identifying the most effective parameters that promise to make the most difference, are the key points of simplification method. The conventional LCA framework and knowledge-based system are employed through the simplification process. Results of previous LCA studies in Australia are used as the specific knowledge that enable the system to generate outputs based on the user’s inputs.Keywords: Life Cycle Assessment (LCA), early design stage, most effective parameters, life cycle environmental performance

“…In view of operational costs, the relevant parameters have been also introduced by a number of researchers. 16,17,18,19,20,21 Being aware of certain limits of the LCC method, the use of Building Information Modelling (BIM) tools emerged as a fresh trend in the construction industry to enhance the building assessment methods towards sustainable architectural design. Referring to the LCC effectiveness in terms of sustainability, Du et al claim that the holistic approach to project results offers a greater value as essential for the decision, whether or not a system would be appropriate.…”

U okviru održivog arhitektonskog projektiranja, problematika energetske učinkovitosti u središtu je interesa svih sudionika u procesu njihovog odlučivanja o optimalnom investiranju u građevinskom sektoru. Ovaj rad predstavlja rezultate studije o procjeni troškova životnog ciklusa [LCC assessment] na temelju informacijskog modeliranja građevine [BIM] koja je dokazala da je metoda primjenjiva u ranim fazama procesa projektiranja.
