“…Electricity consumption for industry and transportation is assumed to be a uniformly distributed within a year, while water withdrawal for building electricity use is dependent on heating degree days (HDD) and cooling degree days (CDD). HDD and CDD, which are derived from outdoor air temperature, are robust indicators for representing heating-and cooling-related energy consumption (Allen, 1976;30 Karimpour et al, 2014). Here, only electricity use for heating and cooling are assumed to be sensitive to the climatic factors.…”

20Human water withdrawal has increasingly altered the global water cycle in past decades, yet our understanding of its driving forces and patterns is limited. Reported historical estimates of sectoral water withdrawals are often sparse and incomplete, mainly restricted to water withdrawal estimates available at annual and country scale, due to a lack of observations at local and seasonal time scales. In this study, through collecting and consolidating various sources of reported data and developing spatial and temporal statistical downscaling algorithms, we reconstruct a global monthly gridded (0.5 degree) sectoral water 25 withdrawal dataset for the period 1971-2010, which distinguishes six water use sectors, i.e. irrigation, domestic, electricity generation (cooling of thermal power plants), livestock, mining, and manufacturing. Based on the reconstructed dataset, the spatial and temporal patterns of historical water withdrawal are analyzed. Results show that global total water withdrawal has increased significantly during 1971-2010, mainly driven by the increase of irrigation water withdrawal. Regions with high water withdrawal are those densely populated or with large irrigated cropland production, e.g., the United States (US), eastern 30 China, India, and Europe. Seasonally, irrigation water withdrawal in summer for the major crops contributes a large percentage of annual total irrigation water withdrawal in mid and high-latitude regions, and the dominant season of irrigation water withdrawal is also different across regions. Domestic water withdrawal is mostly characterized by a summer peak, while water Hydrol. Earth Syst. Sci. Discuss., https://doi.org/10.5194/hess-2017-551 Manuscript under review for journal Hydrol.

CC BY 4.0 License.2 withdrawal for electricity generation has a winter peak in high-latitude regions and a summer peak in low-latitude regions. Despite the overall increasing trend, irrigation in the western US and domestic water withdrawal in western Europe exhibit a decreasing trend. Our results highlight the distinct spatial pattern of human water use by sectors at the seasonal and annual scales. The reconstructed gridded water withdrawal dataset is open-access, and can be used for examining issues related to water withdrawals at fine spatial, temporal and sectoral scales.

“…Based on the literature review, the following conclusions concerning the life cycle carbon emission assessment of a residential building may be drawn (Karimpour et al, 2016): -life span is different for various types of building size and insulation, -depending on the type of heating and other energy costs, the life cycle ranges from 40 to 100 years, -in order to calculate energy cost, usually conversion factor is used. 1…”

Abstract:In the process of making decisions on building a single-family home, many variables of a cost nature should be taken into consideration, which will affect the total level of costs of use of the building in the long-term perspective. Life Cycle Costing (LCC) is a method that can support this process, which is why the main purpose of this article is to analyze the cost of using a single-family home using the LCC method, taking into account environmental aspects that are important in shaping the quality of life of individual households and local communities. In this context, an answer to the following research problem is sought: How to calculate and reduce the costs of using a single-family home in the perspective of its life cycle, taking into account the current and prospective energy and environmental conditions? In order to accomplish the above research objectives, the first part of the article presents the theoretical basis for calculating the costs of maintaining single-family buildings together with a description of use of the LCC method. Next, a case study was presented, within which the longterm costs of maintaining a single-family building were calculated and the pro-ecological possibilities of their reduction were indicated.

“…Life Cycle Assessments (LCAs) and Life Cycle Energy Analyses (LCEAs) of the building envelope are frequently presented in the current literature [1][2][3]. Both LCAs and LCEAs include the following building life stages: (i) Production and Construction (P and C), (ii) Operational Energy (OE) (for cooling, heating, and lighting needs), and (iii) Maintenance to Demolition (MtoD).…”

Abstract:The goal of the current study was to evaluate the environmental damage from three flat roof technologies typically used in Israel: (i) concrete, (ii) ribbed slab with concrete blocks, and (iii) ribbed slab with autoclaved aerated blocks. The roofs were evaluated using the Life Cycle Assessment (LCA) methodology. The Production and Construction (P and C), Operational Energy (OE), and Maintenance to Demolition (MtoD) stages were considered. The roofs were modeled based on an office building module located in the four climate zones of Israel, and the hierarchical ReCiPe2008 Life Cycle Impact Assessment (LCIA) method was applied. The percent difference of one, which is the default methodological option of ReCiPe2008, and an ANOVA of the six methodological options of ReCiPe2008 were used. The results revealed that (i) in a hot climate, the best roof technology can be selected by considering only the OE stage, whereas in a mild climate, both the OE and P and C stages must be considered; (ii) in a hot climate, the best roof technology is a concrete roof, but in a mild climate, the best options are ribbed slab roofs with concrete blocks and autoclaved aerated blocks; and (iii) the conjugation of ReCiPe2008 with a two-stage nested ANOVA is the appropriate approach to evaluate the differences in environmental damage in order to compare flat roof technologies.
