“…This distinction is also reflected in some mandatory regulations [15,16], e.g., the Swiss Minergie ® certification system, and technical standards [17,18]. This paper is mainly devoted to exploring the first area, with the understanding that in a context such as the one described, a traditional LCA study may be difficult to apply [19]; furthermore, the use of environmental certifications, such as Environmental Product Declarations (EPDs), seems intended for a limited number of projects, buildings, and countries [20].…”

“…This means a transition from an all-encompassing assessment approach derived from a traditional LCA study, to one that considers two categories of effects. It is a simplification, but it should be seen as an opportunity to extend the applicability of methods and tools for assessing the building life cycle [20][21][22][23]. In addition, these indicators are relatively easy to interpret.…”

Analysis and Assessment of the Building Life Cycle. Indicators and Tools for the Early Design Stage

Construction is a crucial sector in terms of worldwide environmental impacts. Building material production along with transport and demolition are no exception, because in the last decades, they have constantly increased their carbon dioxide (CO2) emissions. Actions and initiatives are therefore important to tackle the relationship between buildings and climate change. Particularly, it is necessary to develop Life Cycle Assessment (LCA) tools useful to calculate the environmental impact of buildings and to make them accessible to designers and stakeholders acting in the building sector. The article aims to contribute to the international debate about environmental assessment indicators for buildings and the simplified LCA based tools. The Embodied Energy (EE) and the Embodied Carbon (EC) have been investigated. The former, related to primary energy content; the latter, associated with the equivalent carbon dioxide emissions. EE and EC have been used as indicators for the development of a calculation tool named EURECA, for assessing the environmental impact of the building over its life cycle, as defined by the EN 15978:2011 standard. The Solar Decathlon Latin America and Caribbean’s house designed and built by an international academic team has been an opportunity to check the indicators and the tool’s effectiveness.

“…In an effort to reduce the global carbon footprint of construction, low-energy buildings must use low embodied energy and low embodied carbon materials and construction methods to decrease their impact. Lupíšek et al (189) proposed different strategies to decrease both embodied energy and carbon through three steps: (a) reduction of the amount of materials needed throughout the entire life cycle through optimization of the layout plan, optimization of the structural system, low-maintenance design, flexible and adaptable design, and components service life optimization; (b) substitution of traditional materials for alternatives with lower environmental impacts with reuse of building parts and elements, utilization of recycled materials, substitution for bio-based and raw materials, and use of innovative materials with lower environmental impacts, design for deconstruction, and use of recyclable materials; and (c) reduction of the construction stage impact.…”

“…One of the examples that Lupíšek et al (189) present shows that substituting a masonry structure designed according to current standards by a masonry structure in a Passive House building increased the embodied energy by 8% but decreased the embodied carbon by 9%, showing that embodied energy and embodied carbon show decoupling in their accounting. Moreover, if the building is constructed with a light reinforced concrete with timber envelope, the embodied energy decreases 10% from the reference building and the embodied carbon by 32%.…”

The building sector is responsible for 39% of process-related greenhouse gas emissions globally, making net- or nearly-zero energy buildings pivotal for reaching climate neutrality. This article reviews recent advances in key options and strategies for converting the building sector to be climate neutral. The evidence from the literature shows it is possible to achieve net- or nearly-zero energy building outcomes across the world in most building types and climates with systems, technologies, and skills that already exist, and at costs that are in the range of conventional buildings. Maximizing energy efficiency for all building energy uses is found as central to net-zero targets. Jurisdictions all over the world, including Brussels, New York, Vancouver, and Tyrol, have innovated visionary policies to catalyze the market success of such buildings, with more than 7 million square meters of nearly-zero energy buildings erected in China alone in the past few years. Since embodied carbon in building materials can consume up to a half of the remaining 1.5°C carbon budget, this article reviews recent advances to minimize embodied energy and store carbon in building materials. Expected final online publication date for the Annual Review of Environment and Resources, Volume 45 is October 19, 2020.

“…Many researchers deal with various wall fragments with advanced material forms and their characteristics, such as decrement factor and time lag [1], reduction of embodied energies and carbon [2], incorporation of transparent thermal insulations [3], vast analysis of thermal bridges in structures [4] and also with green roofs [5]. It is generally known that building envelope is one of the most important elements of the building.…”

Main aim of this paper is to illustrate the experimental partial results of a study on various exterior wall fragments. The study was performed for selected wall fragments and time periods, with attention focused also on wall orientation (East and South) with identical layering and also on dynamic thermal parameters connected to the thermal comfort during summer and winter. Evaluation is done for real measured climate conditions in the area of experimental laboratory (exterior – University of Zilina) and interior conditions set according to the Slovak standard. For needs of the long-term experiment (since March 2017), temperature and relative humidity between layers are monitored. This paper deals specifically with the temperature measurement of selected days. For future publications also coupled heat-air-moisture transport analysis is intended. In this part of analysis, some extreme boundary conditions were selected and reviewed from the point of view of measured temperature inside the wall. Temperature peaks are characterized with respect to exposure to real atmospheric conditions.
