Past evaluations of the success of wastewater treatment and submarine outfall placement and operation have considered only a limited number of parameters affecting the marine and onshore environments. Important questions regarding the best allocation of available funds have not been adequately addressed. The relative contamination of the sea from airborne and landwash contaminants has not been considered. Neither has the increased air pollution deriving from the energy required for advanced treatment. Similarly, regular epidemiological studies to evaluate actual changes in morbidity arising from drastic changes in treatment and disposal have not been made prior to very large committments of funds. Most importantly, little attention has been given to the relative ranking of all environmental risks within a catchment area. The net result is that, when all factors are considered, the very large expenditures and increased energy use for sanitary wastewater treatment and outfall disposal will have a net negative effect on the physical and societal environment. The City of Los Angeles and the Los Angeles Metropolitan area can be used to illustrate this probability.

In this work, we present results from the largest study of measured, whole-building energy performance for commercial LEED-certified buildings, using 2016 energy use data that were obtained for 4417 commercial office buildings (114 million m2) from municipal energy benchmarking disclosures for 10 major U.S. cities. The properties included 551 buildings (31 million m2) that we identified as LEED-certified. Annual energy use and greenhouse gas (GHG) emission were compared between LEED and non-LEED offices on a city-by-city basis and in aggregate. In aggregate, LEED offices demonstrated 11% site energy savings but only 7% savings in source energy and GHG emission. LEED offices saved 26% in non-electric energy but demonstrated no significant savings in electric energy. LEED savings in GHG and source energy increased to 10% when compared with newer, non-LEED offices. We also compared the measured energy savings for individual buildings with their projected savings, as determined by LEED points awarded for energy optimization. This analysis uncovered minimal correlation, i.e., an R2 < 1% for New Construction (NC) and Core and Shell (CS), and 8% for Existing Euildings (EB). The total measured site energy savings for LEED-NC and LEED-CS was 11% lower than projected while the total measured source energy savings for LEED-EB was 81% lower than projected. Only LEED offices certified at the gold level demonstrated statistically significant savings in source energy and greenhouse gas emissions as compared with non-LEED offices.

Decision Support Process

Building energy conservation measure (ECM) of insulation materials suitable for the domestic situation in the construction sector (passive) is established. The ECMs of insulation materials were classified into walls, roofs, and floors. Also, economic evaluation databases, which are composed of material costs, labor costs, and expenses for constructed alternatives, were built. After setting the target building and deriving the ECM list of insulation materials for the target building, the energy use evaluation and economic evaluation were performed for each constructed alternative. Based on this, the optimal building energy conservation measure of the target building was derived by applying the decision-support process.

AbstractObjectiveHow food is produced and consumed has consequences for ecosystems, such as resource use and greenhouse gas (GHG) emission among others. The Mediterranean diet (MedDiet) was proposed as a sustainable dietary model, due to its nutritional, environmental, economic and sociocultural dimensions. However, further evidence is needed. Thus, our objective was to evaluate the impact on resource (land, water and energy) use and GHG emission of better adherence to the MedDiet in a Mediterranean Spanish cohort.DesignWe analysed the dietary pattern of participants through a validated FFQ. The outcomes were land use, water and energy consumption and GHG emission according to MedDiet adherence. The specific environmental footprints of food item production and processing were obtained from different available life-cycle assessments.SettingSpanish university graduates.SubjectsParticipants (n20 363) in the Seguimiento Universidad de Navarra (SUN) cohort.ResultsBetter adherence to the MedDiet was associated with lower land use (−0·71 (95 % CI −0·76, −0·66) m2/d), water consumption (−58·88 (95 % CI −90·12, −27·64) litres/d), energy consumption (−0·86 (95 % CI −1·01, −0·70) MJ/d) and GHG emission (−0·73 (95 % CI −0·78, −0·69) kg CO2e/d). A statistically significant linear trend (P<0·05) was observed in all these analyses.ConclusionsIn this Mediterranean cohort, better adherence to the MedDiet was an eco-friendly option according to resource consumption and GHG emission.

Input Output Analysis

From an average annual growth rate point of view, it might be concluded that the government's efforts in reducing Korea's GHG emission have been making progress; the growth rate of South Korea's GHG emission (4.8%) was less than that of its primary energy consumption (6.2%) during 1990–2000. To cope with a more strict protocol worldwide, South Korea should avoid the usual political rhetoric or declaration of principles and it should launch an effective action. Such a transition from a policy perspective would begin by the analysis of the interrelations among economic activities, energy use, and GHG emissions. The application of an input-output approach, which incorporates a material flow analysis, could be a very useful tool for such an analysis. In this study, four sequential 96 × 96 hybrid units energy IO tables from 1985 to 2000 were generated. Using these four sequential matrices, the energy intensities and the GHG emission intensities, caused by energy use, were estimated for each sector. It was revealed that even though the energy consumption and GHG emissions have increased, the intensities have gradually improved in Korea. The estimated values were compared to national statistics and the differences were found to be acceptable. It was found that the energy input-output analysis can supply useful data for energy and environment policy makers. Some recommendations were made to improve this model.
