TL;DR: In this paper, a life cycle budget for the complete existence of a green construction for 80 years by using life cycle costing technique was established and it was shown that future costs are 5.7% greater than the initial construction cost.

TL;DR: The results indicated that light steel frame houses present a better behavior than other conventional alternatives, and the integration of building information modelling with LCA and LCCA in the design phase can lead to the development of more sustainable houses.
Abstract: Despite insufficient housing facilities, particularly in developing countries, construction systems are generally selected intuitively or based on conventional solutions sanctioned by practice. The present study aims to evaluate different options for the design of low-income housing in Brazil by integrating the life cycle assessment (LCA) into the decision-making process. To achieve this objective, three single-family projects with different construction systems were selected and analyzed. The most sustainable design was selected through the analytic hierarchy process (AHP). The considered parameters, which were obtained through a survey with professionals and customers, included cost, environmental impact, thermal comfort, construction time, and cultural acceptance. LCA and life cycle cost assessment (LCCA) were performed with the frontier’s system considering the cradle-to-gate cycle, which included the extraction of raw materials, manufacture of building materials, and housing construction. The projects were modelled using Autodesk Revit software with the Tally application for LCA evaluation. The results indicated that light steel frame houses present a better behavior than other conventional alternatives, and the integration of building information modelling with LCA and LCCA in the design phase can lead to the development of more sustainable houses.

TL;DR: In this paper , the authors analyzed livelihood security funding and opportunities for ecosystem restoration, drawing on India's Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), the world's largest livelihood security program.
Abstract: Earth faces an unprecedented ecological crisis: the destruction of its ecosystems. Despite increasing interest in restoration, including through the UN Decade on Ecosystem Restoration (Decade), lack of financing and resources mean efforts to reverse degradation have advanced slowly. Restoration efforts require new approaches to ensure the needs of different stakeholders are met. However, analyses of policies and opportunities that help to finance restoration while improving socioecological outcomes, are lacking. This paper analyzes livelihood security funding and opportunities for ecosystem restoration, drawing on India's Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), the world's largest livelihood security program. The paper analyzes MGNREGA's performance between financial years 2013–2021, focusing on the financing of ecosystem restoration-related works, community mobilization and policy implementation in the early part of the COVID-19 pandemic. Then, the paper reflects on the benefits and shortcomings of MGNREGA and considers wider lessons for the Decade. MGNREGA generated significant funding flows and numbers of projects nationally, which can contribute to ecosystem restoration. Policy design enabled the continuation and increase of works even during the first year of the COVID-19 pandemic. Our findings demonstrate the potential of linking ecosystem restoration with development policies to unlock funds, on a national scale. To maximize contributions to ecosystem restoration nevertheless requires capacity building, inclusion of environmental indicators and integration of best ecosystem restoration practices.

TL;DR: In this paper, a solid waste treatment model that is suitable to be applied in Indonesia was proposed by benchmarking in other countries, doing mathematical calculations using life cycle cost analysis, and validating experts.
Abstract: Solid waste management is needed by each region as a response to population growth. Nevertheless, there are still many areas that have not been able to provide ideal facilities for good solid waste management. One solution that can be done is to create a solid waste treatment model that is suitable to be applied in Indonesia. By benchmarking in other countries, doing mathematical calculations using life cycle cost analysis, and validating experts. The step resulted in a suitable model applied in Indonesia, namely Waste to Energy with a financing scheme of 60% for the government and 40% for the private sector, an internal rate of return (IRR) of 33.11% and an assumed repayment period of 5 years 122 days.
