“…The results obtained for NPC are overall comparable to those of similar studies [55,56], especially with respect to the cost category contribution. However, LCC studies are very specific and related to the case study, as well as to the assumptions for the main economic parameters.…”

Buildings currently play a fundamental role for the achievement of the sustainable development goals as they are responsible for several environmental, social, and economic impacts. Energy renovation projects of existing buildings can support the reduction of environmental impacts by leading, at the same time, to economic and social advantages. In this paper, the life cycle assessment and life cycle costing methodologies were used in a combined performance assessment applied to a case study, i.e., the energy renovation project of a single-family house in Norway. Several scenarios based on alternative energy efficiency measures were analyzed, and life cycle environmental and economic indicators were computed, i.e., global warming potential (GWP), cumulative energy demand (CED), and net present cost (NPC). The results demonstrated the close to negative linear regression between the environmental and economic indicators computed. However, the values of CED and GWP for the best scenarios in environmental terms were respectively 50% and 32% lower than the values of the worst scenarios, while their NPC was around 6% higher than the lowest values. The findings can be helpful in the decision-making context towards a meaningful combination of environmental and economic assessments in building energy renovation projects for selecting the most sustainable scenario.

“…The LCC models, calculation methods and/ or tools designed by researchers were then often tested in one or more real cases (e.g. Arja et al, 2009;Brown et al, 2013;Risholt et al, 2013;Zhang et al, 2011). Gluch (2014) concluded that most researchers justify their efforts with practitioners' need for 'customized' LCC, however, without empirical support about the nature of the need.…”

Abstract. Real estate-and property owners' rationales behind the adoption of Life Cycle Costing (LCC) respectively how LCC is actually used in renovation projects, is investigated through empirical data from a questionnaire survey sent to managers in Swedish real estate organisations. The study shows a positive attitude towards LCC. It is perceived to as a flexible and multi-functional tool with a familiar monetary format. Nevertheless, the study also reveals simplistic and undeveloped views of how to use LCC. While much research has focused on developing sophisticated LCC tools, the findings indicate that practitioners' interest in these refinements seems limited. The importance of understanding that LCC is used in a context of multiple and partly competing institutional logics of renovation is emphasised. The paper contributes to a more informed research in development of LCC tools as well as better informed LCC use among real estate and property owners.

“…According to this standard, LCC is defined as a technique which enables comparative cost assessments to be made over a specified period of time, taking into account all relevant economic factors, both in terms of initial investment cost and future operational cost. The net present value (NPV) may be described as the sum of the discounted benefit of an option less the sum of the discounted costs [23] and was adopted for the LCC calculation on the basis of existing literature [6,13,[24][25][26]]. An energy efficient renovation of a building requires an investment cost, but generates savings in the energy consumption over the life span of the building.…”

Page 1 of 30A c c e p t e d M a n u s c r i p t The building sector is well known to be one of the key energy consumers worldwide. The renovation of existing buildings provides excellent opportunities for an effective reduction of energy consumption and greenhouse gas emissions but it is essential to identify the optimal strategies. In this paper a multi-criteria methodology is proposed for the comparative analysis of retrofitting solutions. A c c e p t e d M a n u s c r i p t far from being optimal solutions. The required additional investment, which is needed to obtain an overall performance improvement of the envelope compared with the common practice to date, is relatively low (8%) considering the obtained life cycle environmental and financial savings (43% and 45% respectively).
