    Embodied carbon and construction cost differences between Hong Kong and Melbourne buildings

    Limiting the amount of embodied carbon in buildings can help minimize the damaging impacts of global warming through lower upstream emission of CO2. This study empirically investigates the embodied carbon footprint of new-build and refurbished buildings in both Hong Kong and Melbourne to determine the embodied carbon profile and its relationship to both embodied energy and construction cost. The Hong Kong findings suggest that mean embodied carbon for refurbished buildings is 33-39% lower than new-build projects, and the cost for refurbished buildings is 22-50% lower than new-build projects (per square metre of floor area). The Melbourne findings, however, suggest that mean embodied carbon for refurbished buildings is 4% lower than new-build projects, and the cost for refurbished buildings is 24% higher than new-build projects (per square metre of floor area). Embodied carbon ranges from 645-1,059 kgCO2e/m2 for new-build and 294-655 kgCO2e/m2 for refurbished projects in Hong Kong, and 1,138-1,705 kgCO2e/m2 for new-build and 900-1,681 kgCO2e/m2 for refurbished projects in Melbourne. The reasons behind these locational discrepancies are explored and critiqued. Overall, a very strong linear relationship between embodied energy and construction cost in both cities was found and can be used to predict the former, given the latter

    INNOVATIONS AND SUSTAINABILITY ISSUES INVOLVED IN GREEN PROJECT MANAGEMENT

    Get PDF
    The paper describes the attempt made in the direction of innovative approach to management and sustainability of Green projects concept. Green project concept involved the practice of increasing the efficiency with which building use resources-energy, water, materials, while reducing building impact on human health and the environment. Atmosphere above the earth has suffered high degree of pollution from buildings in recent times resulting in destabilization of ecosystem and ozone layer depletion which culminates in global warming phenomenon. In order to curtail the effect of negative impact of building on human health and environment, the complete building life cycle from design to post construction period should be thoroughly monitored. To this end, this study attempt, to describe innovative approaches to a sustainable Green project development including the attendant sustainability issues

    Disclosing environmental and sustainability practices and initiatives in the annual reporting process of property investors: evidence from Malaysia

    Get PDF
    Investors around the world are increasingly recognising the importance of embedding environmental, social and governance issues when making property investment decision or sustainable and responsible investment (SRI). The objective of this paper is to examine the implementation of environmental, social practices of property investors in Malaysia as revealed through published company material. Content analysis is used in this research. Analysis was conducted of potential SRPI (Socially Responsible Property Investment) or ESG (Environmental, Social and Governance) initiatives of all (13) Real Estate Investment Trusts (REITs), together with a selection of property investment companies and key institutional investors using publicly available company literature. The websites and annual reports of these investors from 2007-2009 were examined in order to identify activities, strategies contributing to the progress of sustainable and responsible property investment. The progress made was also compared with progresses made in other countries including UK, USA and Australia. The study indicates that although some of the Malaysian REITs and property investment companies are beginning to adopt sustainability practices this is less embedded than in other major countries notably Australia. The study also shows that the sustainability agenda is skewed more to notion of corporate philanthropy than environmental issues

    Urban Goods Movement and Local Climate Action Plans: Assessing Strategies to Reduce Greenhouse Gas Emissions from Urban Freight Transportation

    Get PDF
    This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we wished to focus on efforts to reduce GHG emissions from freight transport specifically. We analyzed 27 advanced local CAPs to determine the degree to which freight transport was targeted in goals and strategies to reduce GHG emissions. We found only six CAPs that included direct measures or programs to reduce freight emissions. Many of the CAPs mentioned general transportation objectives such as lowering vehicle miles traveled or reducing emissions from city-owned vehicle fleets, but most did not include strategies or actions that explicitly targeted freight transport. We identified the specific strategies and actions that cities are taking to address GHG emissions from freight transport, such as working with the freight community to promote anti-idling and encourage transitions to electric and alternative fuel delivery vehicles. We also analyzed freight transport plans relevant for the same cities, and found that most do not explicitly mention reducing GHG emissions. Most of the freight plans are focused on improving reliability and efficiency of freight movement, which would likely have the ancillary benefit of reducing GHG emissions, but that goal was not explicitly targeted in most of these plans. Based on our findings, we recommend that cities specifically target freight transport goals and strategies in their CAPs and better coordinate with planners developing freight transport plans to identify GHG emission reduction approaches

    Renewable energy for Latium: looking for innovative technologies in PV and solar thermal field.

    European METTTES Project, financed within the FP6-2005-INNOV-7 call, aimed to test a new methodology to encourage the launch of transnational collaborations technology based among European small and medium enterprises (SMEs) and/or research organizations, focusing its attention on regional technology demand, influenced by changes in regulations and standards and fostered by local incentives. METTTES considered European directives, national, regional and local measures (i.e. incentives, projects, etc.) potentially influencing companies’ behavior. In addition, METTTES has also taken into account the IPPC (Integrated Pollution Prevention and Control) Directive 96/61/EC, whose purpose is to achieve an integrated pollution prevention and control from the industrial activities. At the end of these analysis, METTTES derived the technology demand not from the needs of individual enterprises, but instead from the regional system. A certain number of Regional Demand Profiles (RDPs) on particular interesting industrial fields have been collected at European level; the documentation includes a comprehensive analysis and detailed presentation of current regional technology demands and forecasts as well as foresight regarding future demands triggered by legal requirements new administrative regulations or national environmental policy and BATs analysis. Each RDP document has been edited with the collaboration of local stakeholders and administrations and by auditing involving SMEs. Results of each RDP have been high quality Technology Requests (TRs) expressed by local companies which seek technological collaboration. For Latium Region this task has been performed by CNR in the sector of PV and solar thermal technologies

    Buffalo Habitat for Humanity: The Challenges and Prospects of Green Building

    Get PDF
    Habitat for Humanity Buffalo has operated since 1985, and in that time has rehabilitated or built more than 150 homes in the cities of Buffalo and Lackawanna. An affiliate of Habitat for Humanity International (HFHI), Habitat builds affordable housing for qualified low-income people. Once approved, homeowners must put 500 hours of “sweat equity” into Habitat projects, including their homeowner education. In return, they receive a zero-interest mortgage, the proceeds of which pay their property taxes and homeowner’s insurance, as well as support the rehabilitation or construction of more Habitat homes in the Buffalo area
