Study Results

Energy consumption in public buildings increased drastically over the last decade. Significant policy actions towards the promotion of energy efficiency in the building sector have been developed involving sustainable low-CO2-emission technologies. This paper presents the results of an economic–environmental valuation of a standard energy retrofit project for a public building in a Mediterranean area, integrating a life-cycle assessment (LCA) into the traditional economic–financial evaluation pattern. The study results show that simple retrofit of sustainable low-CO2-emission strategies such as wooden double-glazed windows, organic external wall insulation systems, and green roofs can reduce energy needs for heating and cooling by 58.5% and 33.4%, respectively. Furthermore, the implementation of an LCA highlights that the use of sustainable materials reduces the building’s carbon footprint index by 54.1% after retrofit compared to standard materials, thus providing an additional increase in the socio-environmental–economic–financial results of 18%. Some proposals are made about the accounting of the replacement costs and the residual value as requested in the logic of life-cycle cost (that is the economic extension of the LCA), namely concerning the method to take into account the replacement costs and the residual value. The economic calculation highlights the fundamental role played by tax benefits supporting the building energy retrofit, also in temperate climate zones, thus allowing the creation of environmental benefits in addition to remarkable cost savings.

The Impact

Research was conducted to indicate the impact of the increased flow of thermal insulation materials on the environment due to the implementation of the new regulations on energy efficiency of buildings. The regulations on energy efficiency of buildings in Serbia came into force on 30 September 2012 for all new buildings as well as for buildings in the process of rehabilitation and reconstruction. For that purpose, the carbon footprint was analyzed in three scenarios (BS, S1 and S2) for which the quantities of construction materials and processes were calculated. The life cycle analysis (LCA), which is the basis for analyzing the carbon life cycle (LCACO2), was used in this study. Carbon Calculator was used for measuring carbon footprint, and URSA program to calculate the operational energy. This study was done in two phases. In Phase 1, the embodied carbon was measured to evaluate short-term effects of the implementation of the new regulations. Phase 2 included the first 10 years of building exploitation to evaluate the long-term effects of the new regulations. The analysis was done for the period of 10 years, further adjustments to the regulations regarding energy efficiency of the buildings in Serbia are expected in accordance with EU directives. The study shows that, in the short-run, Scenario BS has the lowest embodied carbon. In the long-run, after 3.66 years, Scenario S2 becomes a better option regarding the impact on the environment. The study reveals the necessity to include embodied carbon together with the whole life carbon to estimation the impact of a building on the environment.

Proper Design

Purpose The purpose of this study is to investigate the energy efficiency and life cycle carbon footprint of temporary homes in Japan after the Great Eastern Tohoku Earthquake in 2011. Design/methodology/approach An energy simulation and life cycle assessment have been done for three alternative shelter models: prefabricated shelters, wooden log shelters and sea container shelters. Findings Shelter materials have a very high share of life cycle emissions because the use period of temporary homes is short. Wooden shelters perform best in the comparison. The clustering of shelters into longer buildings or on top of each other increases their energy efficiency considerably. Sea containers piled on top of each other have superb energy performance compared to other models, and they consume even less energy per household than the national average. However, there are several gaps of knowledge in the environmental assessment of temporary homes and field data from refugee camps should be collected as part of camp management. Originality/value The findings exemplify the impacts of the proper design of temporary homes for mitigating their energy demand and greenhouse gas emissions.

Energy Efficiency Standards

The China construction industry accounts for about 30% of total energy consumption, a high proportion of the energy consumed, which causes a large amount of emissions of greenhouse gas. This paper takes a look at the China national standard GB50189-2005, Design Standard for Energy Efficiency of Public Buildings, the ASHRAE90.1 of US and the part L of UK, and then compares the similarities and differences between the three design standards. At the end, relevant suggestion to tackle these weaknesses for long-term energy efficiency development in public buildings are proposed in this paper.

Carbon Footprint Reduction

Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Energy consumption and carbon footprint are among the most frequently adopted and investigated environmental performance metrics. The purpose of this paper is to serve two objectives — first, it provides a review of recent developments for carbon footprint reduction in manufacturing processes and supply chain operations. Second, a future vision is shared toward developing a method for reducing carbon footprint through simultaneous consideration of manufacturing processes and supply chain activities. The approach is demonstrated by developing analytical models for alternative manufacturing processes and supply chain networks associated in the manufacture of a bicycle pedal plate to realize its potential in assessing energy and GHG (greenhouse gas) emissions. The sustainable design and manufacturing research community should benefit from the review presented. In addition, a point of departure for concurrent consideration of multiple stages of the product life cycle for environmental performance is established for the research community to move current efforts forward in pursuit of environmental, economic, and social sustainability.
