“…During the past years, building design to minimize consumption during the use phase has been intensified [4], for that reason special attention to impacts in other phases as a result of the reduction of such consumption must be shown, especially during the production phase [5,6].…”

This paper demonstrates how to achieve energy savings in the construction and operation of buildings by promoting the use of life cycle assessment techniques in the design for new buildings and for refurbishment. The paper aims to draw on the application of a specific methodology for low energy consumption, integrated planning, environmental performance evaluation of buildings, and design for sustainability and LCA techniques applied to buildings. The ENergy Saving through promotion of LIfe Cycle assessment in buildings (ENSLIC) methodology based on LCA for use in an integral planning process has been promoted to stakeholders who require a means to optimize the environmental performance of buildings. Feedback from the stakeholders has facilitated the creation of simplified LCA guidelines, a systematic approach guiding the user through the alternative options regarding software choices, their strengths and weaknesses, the databases available, the usefulness of different indicators, aggregation, definition of limits and options for simplifying the process. As a result, this paper presents the applied results of a case study where this methodology is implemented serving as an energy savings evaluation tool for decision makers, end-users, professionals involved in the different stages of construction, etc. Finally, it is demonstrated how LCA can facilitate comparisons between different buildings, showing the influence of all variables on a building's life cycle environmental impact and showing the potential for energy savings. Removing market barriers to sustainable construction is actually stricter and this is good news for promoting higher energy efficiency in buildings.

“…Using aerogel between two concrete should be valuable, so the first wall consists of two cast concrete with aerogel between them. Timber is the superior material for structural and cladding systems, so the second wall is designed to include timber products [3]. To challenge the issue, the third wall is chosen to design with aerated concrete and EPS (expanded polystyrene).…”

“…In addition, embodied energy consumes the rest of the LCA behind the little impact of demolition and transportation [2]. This is clear that with the increasing life span of a building, the significance of the embodied energy becomes inconsiderable [3].…”

Annual energy consumption and annual Global Warming Potential (GWP) decreases with the improving of the energy performance of the facade, whereas the embodied energy and embodied GWP increases due to the extra material and products applied. This study analyses the relation between the embodied energy and the energy consumption of a house during the life span of the buildings, and the results represented separately in tables and figures. The study uses Life Cycle Assessment (LCA) framework as a tool to conduct a partial LCA, from cradle to site of the construction and energy consumption during usage phase of the buildings with three different wall types through 50 years usage phase. According to this study, laminated timber and aerated concrete are better choices than cast concrete for both types of buildings because of lower density and lower U value.

The growing concern about the development of sustainable production systems leads organizations to seek the support of management tools for decision-making. Considering the whole life cycle of the product, the Life Cycle Assessment (LCA) has an important role in this scenario.The objective of this paper is to present, through the theoretical discussion, the role of LCA in strategic planning of the organization. It showed the enormous potential for decision making on the environmental aspect, but also the critical factor in the development shares in the competitive context. The use of LCA can reduce the environmental impacts of the system under study (primary purpose) and guide the range of advantages in the fields of marketing, legislation and environmental labeling, competitive strategies, efficiency resources use of and others.
