Sustainable construction through energy management practices in developing economies: an analysis of barriers in the construction sector

Abstract: In the recent era, energy management practices (EMPs) have gained significant importance in developed countries, due to their cost efficiency and the potential to protect the environment. However, developing countries are not particularly serious about adopting and implementing sustainable construction practices, due to the different barriers that hinder them from doing so. Therefore, the complete adoption of effective EMPs is still at the initial stage. The objective of this study is to identify the barriers to EMPs adoption, in the construction sector of Pakistan. Initially, the barriers were identified from the earlier studies and screened by the fuzzy Delphi method (FDM). These screened barriers were then evaluated through the ISM. The results of the ISM show that there happens to be a “lack of communication and collaboration among project stakeholders,” “attitudinal, cultural and behavioral resistance to adopt EMPs”, “lack of top management support and interest in energy management issues,” “no condition for implementing EMPs on construction site,” and “lack of financing schemes to implement energy management technology,” as the top barriers to EMPs adoption in the construction projects pertaining to Pakistan. Thus in this regard, this study empirically contributes to EMPs literature that is based on the developing countries and supports the policymakers in developing appropriate strategies to reduce energy consumption in construction projects—especially in developing countries.

Flood Footprint Assessment: A Multiregional Case of 2009 Central European Floods.

Abstract: Hydrometeorological phenomena have increased in intensity and frequency in last decades, with Europe as one of the most affected areas. This accounts for considerable economic losses in the region. Regional adaptation strategies for costs minimization require a comprehensive assessment of the disasters' economic impacts at a multiple-region scale. This article adapts the flood footprint method for multiple-region assessment of total economic impact and applies it to the 2009 Central European Floods event. The flood footprint is an impact accounting framework based on the input-output methodology to economically assess the physical damage (direct) and production shortfalls (indirect) within a region and wider economic networks, caused by a climate disaster. Here, the model is extended through the capital matrix, to enable diverse recovery strategies. According to the results, indirect losses represent a considerable proportion of the total costs of a natural disaster, and most of them occur in nonhighly directly impacted industries. For the 2009 Central European Floods, the indirect losses represent 65% out of total, and 70% of it comes from four industries: business services, manufacture general, construction, and commerce. Additionally, results show that more industrialized economies would suffer more indirect losses than less-industrialized ones, in spite of being less vulnerable to direct shocks. This may link to their specific economic structures of high capital-intensity and strong interindustrial linkages.

Ex-ante versus ex-post destination information model for on-demand service ride-sharing platform

Abstract: The two leading on-demand service ride-sharing platforms in China have used very different destination information sharing models in the past period of time: Didi Chuxing uses an ex-ante destination information model (ADI) in which drivers can acquire the passengers’ destination information before receiving the orders, whereas Uber in China uses an ex-post destination information model (PDI) in which participants can only obtain the information after receiving the requests. This work compares ADI and PDI to study their impacts on the decisions as well as revenue/welfare of all stakeholders. We show that the PDI model generates more revenue for the platform than the ADI model in most cases, but it undermines the welfare of the passengers. This stands in sharp contrast with the existing views which argue that the ADI model can result in lower consumer surplus. Moreover, the platform can attract participants to choose the PDI model by increasing subsidies or degree of subsidies. Drivers are better off under the PDI model in most scenarios. The only exception is when both the opportunity cost and subsidy are lower or the subsidy is higher. Under this condition, the drivers can be worse off under the PDI model. Finally, if the platform adopts a new subsidy scheme which is related to the income of the participants, drivers are always better off under the PDI model but this model is still not good for the passengers. Besides, the higher demand state and equitable payoff are, the more social welfare under the ADI model it will generate.
