“…Rossi et al [38] compared embodied and operational consumption for a house in three different European locations by considering production, transport to site, operational energy and water use. Rosselló-Batle et al [60] also compared embodied and operational energy demand in a Mediterranean climate by including production stage, maintenance -partially-and operational energy. Several omitted modules were justified by previous research.…”

“…According to Houlihan et al [43], Iddon et al [39], Rossi et al [38], Rosselló-Batle et al [60], if the assessment is focused on comparing embodied and operational impacts, life-cycle stages definition is centered on product stages and energy consumption during use module. In other cases [3,[31][32][33]35,36,40,41,44,45,62,61,105], if the assessment is focused on environmental impact during the life-cycle; product, construction, use and demolition are mostly included, while loads and benefits are hardly considered.…”

Life Cycle Assessment (LCA) is globally recognized as one of the most complete methods for environmental assessment of buildings. Literature assumes that its applications in the building sector are prejudiced regarding complexity and difficulty. However, simplification is necessary, since it can facilitate LCA application in buildings. Moreover, growing interest on reducing environmental impact in the building sector, as well as the relevance of single-family houses on CO2 emissions have become key points on the wide spread of LCA.Therefore, this paper presents a research study about simplification in LCA recent studies applied to singlefamily houses. The review focuses on 20 cases that were analyzed according to ISO 14040, ISO 14044, EN 15978, and EN 15804 standards. The main objective was to identify the simplification strategies assumed in each paper, to clarify and to help to promote further developments on LCA. This paper examines system boundary definition, data sources, life cycle phases included, and environmental impact indicator calculated in case studies. Results show the variety of simplifications identified. They affect physical model definition, life cycle scenario definition and communication of results. In most cases, the functional unit was the complete building, the life cycle scenario definition included production, use and demolition phases, and the most considered environmental impact indicator was GWP. Finally, new challenges and recommendations were defined in order to establish common criteria to develop simplification strategies that allow results comparability in LCA of single-family houses.

“…To obtain these parameters, the authors have used the detailed Unified LIDER-CALENER software tool (HULC), which is the official building energy certification tool in Spain [90], developed by the authors (for more details view Section 3.4). There are quite a few publications developing its use [65,74,[91][92][93][94][95][96], which allowed certain modifications to be made in order to carry out the validation of the proposed methodology. It is important to highlight that previous simulations using a BEP tool have not been detailed because it will be used as a starting point for the methodology, subsequently calibrating the results using the energy consumption measured in the actual buildings.…”

Systematic Simplified Simulation Methodology for Deep Energy Retrofitting Towards Nze Targets Using Life Cycle Energy Assessment

The reduction of energy consumption in the residential sector presents substantial potential through the implementation of energy efficiency improvement measures. Current trends involve the use of simulation tools which obtain the buildings’ energy performance to support the development of possible solutions to help reduce energy consumption. However, simulation tools demand considerable amounts of data regarding the buildings’ geometry, construction, and frequency of use. Additionally, the measured values tend to be different from the estimated values obtained with the use of energy simulation programs, an issue known as the ‘performance gap’. The proposed methodology provides a solution for both of the aforementioned problems, since the amount of data needed is considerably reduced and the results are calibrated using measured values. This new approach allows to find an optimal retrofitting project by life cycle energy assessment, in terms of cost and energy savings, for individual buildings as well as several blocks of buildings. Furthermore, the potential for implementation of the methodology is proven by obtaining a comprehensive energy rehabilitation plan for a residential building. The developed methodology provides highly accurate estimates of energy savings, directly linked to the buildings’ real energy needs, reducing the difference between the consumption measured and the predictions.

“…For existing stock, medium term emissions reduction first involves subsidies for better insulation, heat-recovering ventilation, smart glass, etc. However, producing insulating materials may now induce substantial CO 2 emissions (Rosselló -Batle, Ribas, Moià-Pol, & Martínez-Moll, 2015). Long-term heating and cooling in existing buildings must also be solar thermal and electric, using heat pumps as already extensively used in Japan, with possibly also hydrogen fuel cells.…”

Strategic design of long-term climate policy instrumentations, with exemplary EU focus

et al. 2016

The Paris climate goal requires unprecedented emission reduction, while CO 2 concentrations are now rising faster than ever. Internally inconsistent instrumentation has developed on the go, not fit for deep reduction. Mainly national technology-specific instruments, for example, have made the EU pure cap-and-trade system superfluous and have fragmented electricity markets. Systematic instrumentation design requires an adequate categorization of instruments, newly developed here for that purpose. This instrument ordering links to generality and bindingness. Starting points for any instrumentation design are sparseness, completeness, and non-overlap. Details in instrumentations may further depend on specific circumstances in different countries and regions. Planning & Control starts with technology-specific instrumentation, with subsidies and standards to reduce fossil emissions in electricity production; effective Fleet Standards for transport; dynamic standards and permits regarding industry emissions; and standards and technology subsidies squeezing out fossils use in buildings and appliances. Subsidies create learning curves. Consistency and effectiveness tend to require centralization. Institutionalism uses two core institutional instruments. A comprehensive upstream emission tax with proceeds to the country or state level creates incentives. An open-to-all, real-time priced electricity market enables also small-scale renewables and secondary producers on the grid. Infrastructure is provided publicly. A level playing field results for mostly decentral climate action, both public and private. Policy relevance Technical instrument choices may seem neutral but cannot be so: policy is about choices. Two governance strategies are now mutually competing and counteracting. Planning & Control links to welfare theory and optimization, with broad integration of several policy goals, measurable targets, and deep public-private cooperation. Institutionalism has a background in history, economics, sociology, and political science, with institutions driving long-term development. Incentives and option creation are central, indicating results only roughly. There is strict public-private delimitation. These different views on governance lead to mutually exclusive sets of instruments. Explicit instrumentation strategies are required for consistency, effectiveness, and legitimacy. Internationally, Planning & Control requires binding country caps for (almost) all countries, UN-type. Institutionalism requires a limited agreement on a high rising emission tax, open for all countries to join a starting group, WTO-type. Choices are ultimately based on governance preferences.
