“…But in the case of low energy consumption buildings, the statements above are no longer valid : the fabrication of building elements may contribute to around 30% or even more in the total life cycle energy balance [42,43]. The emissions from heating of buildings is important but the emissions of CO 2 from heating is lower than from other parts of the building sector, indicating the importance of emissions from for example production of building materials [44].…”

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.

“…Other studies show that the energy use during occupancy is larger than the embodied energy and accounts for approximately 80% of a building's total energy use [61][62][63]. In low-energy buildings, the relative impact from materials becomes larger [64][65][66]. From these studies, it follows that the relative impact from "Material and Waste" increases with decreasing energy use and also with decreasing life span.…”

Understanding how Building Environmental Assessments Tools (BEATs) measure and define "environmental" building is of great interest to many stakeholders, but it is difficult to understand how BEATs relate to each other, as well as to make detailed and systematic tool comparisons. A framework for comparing BEATs is presented in the following which facilitates an understanding and comparison of similarities and differences in terms of structure, content, aggregation, and scope. The framework was tested by comparing three distinctly different assessment tools; LEED-NC v3, Code for Sustainable Homes (CSH), and EcoEffect. Illustrations of the hierarchical structure of the tools gave a clear overview of their structural differences. When using the framework, the analysis showed that all three tools treat issues related to the main assessment categories: Energy and Pollution, Indoor Environment, and Materials and Waste. However, the environmental issues addressed, and the parameters defining the object of study, differ and, subsequently, so do rating, results, categories, issues, input data, aggregation methodology, and weighting. This means that BEATs measure "environmental" building differently and push "environmental" design in different directions. Therefore, tool comparisons are important, and the framework can be used to make these comparisons in a more detailed and systematic way.

“…Room air pressure is usually the same as the atmospheric pressure outside (outdoor), in which the standard atmosphere is stated as being 101325pascals or 101.325kPa [4]. The effect of wind blowing onto a building will generate difference of pressure up to 20 Pascals between outside and inside of the building structure and creates variations in the building pressure [5]. Humidity being defined as water vapor in the air, which is the transformation from water to gas state.…”
