Economic impact assessment of carbon pricing of embodied greenhouse gas emissions for commercial office construction

Noller, Caroline J, Built Environment, Faculty of Built Environment, UNSW January 2005 (has links)
A life cycle study was undertaken to assess the economic impact arising from internalised embodied greenhouse gas emissions (GGE) costs for a commercial office building. A limited range of design and materials re-cycling strategies were investigated for their abatement potential. GGE quantities were determined by a hybrid process analysis where input-output data was supplemented with national average data to increase completeness whereby all upstream emissions arising from material inputs to the point of extraction, as well as non-material inputs (e.g. goods and services) into the design and construction process are accounted for. The hypothesis proposed abatement potential of 30%, as measured against the Benchmark Design (BM) would be economically viable in absence of the benefit of early-action credits. The hypothesis was disproved with 15% abatement shown at zero additional capital cost. A Stretch Technology (ST) scenario was investigated which showed 32% abatement potential however the associated marginal capital cost could not be determined. The GGE intensity per meter square of Net Lettable Area (m2 NLA) for the case study building was found to be 5,258 kg CO2-e. The theoretical value of abatement credits was determined at $12 to $1,031 / m2 NLA (depending on price) and is shown to present a reasonable economic and market transformation opportunity at medium range values. The results demonstrate that the cost-push inflation risk posed to commercial office construction is large where the price of embodied GGE is internalised in the economic system. Gross Construction Cost (GCC) increase per square meter is shown to be between 1.5% and 61% (with associated negative IRR impacts between -0.1 to -7%) depending on the GGE price level. An unsustainable cost impact is demonstrated at GGE prices greater than AUD$50 per tonne of carbon dioxide equivalent (AUD$50/ tonne CO2-e). Internalised GGE studies have been largely limited to the operational cost impact arising from GGE of direct end-use rather than from the perspective of total embodied final demand. The results demonstrate the critical nature of embodied abatement strategies for commercial buildings if the internationally accepted 60% global GGE abatement is to be achieved within the relevant timeframe. An average kg CO2-e intensity per dollar of GCC is proposed for the three building models that may be applied to general scenario planning. The scale of economic benefit available for embodied credits is significant and the determination of viable credit mechanisms worthy of further research.

Integrated whole life cycle value evaluation framework for infrastructure megaprojects

Xie, Hongbo, Brenda., 谢洪波. January 2012 (has links)
In the past decades, while many countries planned and undertook more and bigger infrastructure megaprojects, poor performance has marred their delivery, for example through cost overruns, delays, disputes, and shortfalls in expected benefits. It is therefore important to improve performance levels, especially in infrastructure megaprojects that can considerablely influence the economy, society and environment. Project evaluation is an effective tool in project performance management as it provides stakeholders with a management process through which they can learn from the past and perform better in the future. Most of the traditional evaluation approaches emphasize the three basic success criteria of time, budget and quality. However, with the increasing importance of sustainability criteria and concerns, as well as the growing imperatives for stakeholder engagement, it has already been suggested to reconsider and redefine value by also evaluating other factors, such as those related to the environment and society. Therefore, an integrated whole life cycle value (WLCV) evaluation framework is proposed in order to improve infrastructure megaproject WLCV performance. In this study, whole life cycle (WLC) evaluation has a two-fold meaning: (i) the evaluation is based on a set of value factors drawn from a WLCV system; and (ii) this evaluation is a systematic continuous process from the start to the end of the project. However, considering the unique characteristics of every project, a totally fixed or static structure and content framework is neither sufficient nor suitable for the various types of infrastructure megaprojects. The recommended solution is to develop a semi-flexible framework that enables a pre-determined step by step dynamic structure formulation and a flexible WLCV system. In order to measure project WLCV derived from stakeholders’ expectations, from more objective and persuasive perspectives, the relevant value objectives/criteria/indicators, their weightings and targets will be identified, integrated and developed through this WLCV system. Cross-criteria relationships which have not been addressed adequately before, will be dealt with by assigning appropriate weightings. It is also proposed to build a database to store completed project information including various stakeholders’ expectations expressed in the form of value objectives. In order to develop the above proposed framework, a basic literature review was conducted to reveal and analyze the significant evaluation problems, identify trends in stakeholder engagement and develop the concept as well as typical criteria and indicators of project WLCV. Meanwhile evaluation practices, stakeholder engagement in the process of evaluation and WLCV perspectives in the Hong Kong construction industry were examined through a first round of interviews and the first of two focus group meetings. The first focus group meeting, second round interviews and the second focus group meeting were conducted to improve the proposed framework by investigating the importance of assigning an appropriate weighting to each value objective and each group of stakeholders; elaborating the various value criteria to measure value objectives at appropriate points of a project WLC. The findings from literature reviews, interviews, focus group meetings and a case study were integrated and injected into developing the aforementioned framework for building and administering the evaluation of project WLCV in ways that could improve desired project WLC performance. The outputs of the current research are expected to assist clients of infrastructure megaprojects to build a sense of ownership among all the key stakeholders at the outset, and to help motivate all stakeholders to be more co-operative, with a view to jointly targeting and monitoring an agreed project WLCV, thereby helping to achieve better WLC performance on infrastructure megaprojects. The main contributions to knowledge from this research are in developing a comprehensive evaluation methodology which combines and refines relevant components from existing evaluation approaches as well as injects the WLCV concept and criteria into a more holistic approach that is expected to identify and address current inadequacies in infrastructure megaproject delivery. / published_or_final_version / Civil Engineering / Master / Master of Philosophy
