Sustainability and interoperability: An economic study on BIM implementation by a small Civil Engineering firm

[EN] Sustainability and interoperability are two closely related concepts. By analyzing the three fundamental facets of sustainability-economic, ecological and ethical/social-it is easier to address their connection with the concept of interoperability. This paper focuses on the economic aspect, in the field of civil engineering. In this area, due to the local nature of many of the software tools used, interoperability problems are frequent, with few studies addressing the economic impact of this, especially in small engineering firms. The main contribution of this paper is a design methodology for linear works based on the federation of building information modelling (BIM) models created with different software tools, conceived to break the interoperability issues between these applications. As an example, this methodology is applied to a mountain road widening project. A detailed economic analysis of the application of this methodology by an engineering Spanish firm reveals the important cost reductions that the integration of the software tools provides versus the prior practices.The authors wish to acknowledge support from ISTRAM, CivileStudio and the engineering firm for the information provided.Aranda Domingo, JÁ.; Martin-Dorta, N.; Naya Sanchis, F.; Conesa-Pastor, J.; Contero, M.

Towards zero emissions and zero poverty in the Global South: a comparative analysis of South Africa, India and Mexico's approach to development and climate change mitigation

Among the foremost challenges of the 21st century are sustainable development and climate change mitigation. In light of these challenges, this thesis seeks to analyse and compare the extent to which development and climate change mitigation are aligned on a policy level in three countries in the global south, namely South Africa, India and Mexico. These three middle-income countries are plagued by high levels of poverty and large inequality gaps, and address the challenge of reducing GHG emissions in this context. The objectives of this study are fourfold: (1) an analysis of each country’s climate change policies mainly its Nationally Determined Contributions and climate response strategies and assesses to which extent development is addressed; (2) analysis of each country’s national development plans and the extent to which climate change mitigation is addressed; (3) based on the initial analysis, assessing the overall extent to which the development and climate policies are aligned; and (4) a comparative analysis of how each country performed in this regard. The study found that South Africa, India and Mexico are in pursuit of lower carbon development in the years to come. Targets for reducing their emissions in light of climate change considerations have been set and sectoral approaches to low carbon development are illustrated to varying degrees. South Africa was found to have done relatively well in integrating development and poverty alleviation into its national climate policy. The detailed analysis presented in the thesis found this at national scale, while a focus on co-benefits was particularly well integrated in Mexico’s and India’s climate policy. Thus the thesis shows that each country could learn or adopt some approaches to alignment from the other – and that there are several benefits associated with aligning development and climate policies. More research would need to be conducted at a finer scale to identify the trade-offs of certain mitigation actions and this information should be used in future national and sectoral development

NASA Technology Plan 1998

This NASA Strategic Plan describes an ambitious, exciting vision for the Agency across all its Strategic Enterprises that addresses a series of fundamental questions of science and research. This vision is so challenging that it literally depends on the success of an aggressive, cutting-edge advanced technology development program. The objective of this plan is to describe the NASA-wide technology program in a manner that provides not only the content of ongoing and planned activities, but also the rationale and justification for these activities in the context of NASA's future needs. The scope of this plan is Agencywide, and it includes technology investments to support all major space and aeronautics program areas, but particular emphasis is placed on longer term strategic technology efforts that will have broad impact across the spectrum of NASA activities and perhaps beyond. Our goal is to broaden the understanding of NASA technology programs and to encourage greater participation from outside the Agency. By relating technology goals to anticipated mission needs, we hope to stimulate additional innovative approaches to technology challenges and promote more cooperative programs with partners outside NASA who share common goals. We also believe that this will increase the transfer of NASA-sponsored technology into nonaerospace applications, resulting in an even greater return on the investment in NASA

From filthy to filthy rich: Exploring opportunities for social enterprise to improve solid waste management in the Accra Metropolitan Area

Thesis submitted to the Department of Business Administration, Ashesi University College, in partial fulfillment of Bachelor of Science degree in Business Administration, April 2016Cities in developing nations round the world cannot keep up with the vast quantities of solid waste they produce daily. In Accra, Ghana’s capital, despite the fact that about 100% of the waste collection function has been ceded to private waste contractors, about 30% of the waste produced remains uncollected, ending up in gutters, choking drains and blocking waterways. This poses a health risk to the people of Accra Ironically, waste holds economic, environmental and social value, hence its potential benefits are worth exploring and exploiting. Current literature has largely ignored the role of social enterprises in improving waste management in the major cities of developing countries such as Accra. This paper uses the UN-Habitat Integrated Sustainable Waste Management benchmarking methodology, to evaluate waste management in Accra and to identify opportunities for social enterprises to contribute to improved waste management. It was found that there is a lot more that can be done in Accra to improve its current waste collection coverage, controlled disposal as well as recycling rates, which are lagging behind the international median for lower-middle income regions. There is also a vibrant informal sector which social enterprises can organize and integrate into existing waste management structures to contribute to waste segregation, composting and recycling. There are however gaps in the policy framework and legislation for social enterprises which continue to hinder the scope and magnitude of their goal of positive social value creation.Ashesi University Colleg

Deep Reinforcement Learning for the Optimization of Building Energy Control and Management

Most of the current game-theoretic demand-side management methods focus primarily on the scheduling of home appliances, and the related numerical experiments are analyzed under various scenarios to achieve the corresponding Nash-equilibrium (NE) and optimal results. However, not much work is conducted for academic or commercial buildings. The methods for optimizing academic-buildings are distinct from the optimal methods for home appliances. In my study, we address a novel methodology to control the operation of heating, ventilation, and air conditioning system (HVAC). We assume that each building in our campus is equipped with smart meter and communication system which is envisioned in the future smart grid. For academic and commercial buildings, HVAC systems consume considerable electrical energy and impact the personnels in the buildings which is interpreted as monetary value in this article. Therefore, we define social cost as the combination of energy expense and cost of human working productivity reduction. We implement game theory and formulate a controlling and scheduling game for HVAC system, where the players are the building managers and their strategies are the indoor temperature settings for the corresponding building. We use the University of Denver campus power system as the demonstration smart grid and it is assumed that the utility company can adopt the real-time pricing mechanism, which is demonstrated in this paper, to reflect the energy usage and power system condition in real time. For general scenarios, the global optimal results in terms of minimizing social costs can be reached at the Nash equilibrium of the formulated objective function. The proposed distributed HVAC controlling system requires each manager set the indoor temperature to the best response strategy to optimize their overall management. The building managers will be willing to participate in the proposed game to save energy cost while maintaining the indoor in comfortable zone. With the development of Artificial Intelligence and computer technologies, reinforcement learning (RL) can be implemented in multiple realistic scenarios and help people to solve thousands of real-world problems. Reinforcement Learning, which is considered as the art of future AI, builds the bridge between agents and environments through Markov Decision Chain or Neural Network and has seldom been used in power system. The art of RL is that once the simulator for a specific environment is built, the algorithm can keep learning from the environment. Therefore, RL is capable of dealing with constantly changing simulator inputs such as power demand, the condition of power system and outdoor temperature, etc. Compared with the existing distribution power system planning mechanisms and the related game theoretical methodologies, our proposed algorithm can plan and optimize the hourly energy usage, and have the ability to corporate with even shorter time window if needed. The combination of deep neural network and reinforcement learning rockets up the research of deep reinforcement learning, and this manuscript contributes to the research of power energy management by developing and implementing the deep reinforcement learning to control the HVAC systems in distribution power system. Simulation results prove that the proposed methodology can set the indoor temperature with respect to real-time pricing and the number of inside occupants, maintain indoor comfort, reduce individual building energy cost and the overall campus electricity charges. Compared with the traditional game theoretical methodology, the RL based gaming methodology can achieve the optiaml resutls much more quicker

New diversification strategies for the Japanese alcohol industry

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2007.Includes bibliographical references (p. 238-241).Japanese major alcoholic beverage companies, whose businesses are mainly the production and sale of beer products, stand at a strategic crossroads. There are several reasons: a slow decrease in the Japanese population, which leads to a smaller drinking population; diversification of customers' tastes and preferences; a totally saturated beer and low-alcohol beverage market; and a globalization trend that is now entering Asian countries. Therefore it is essential for the alcoholic beverage companies to adopt strategies for future sustainability--one to strengthen its core liquor business and offer a range of beverages other than beer; the other is to expand business opportunities into areas other than the liquor business. These diversified businesses are basically either vertically integrated or founded upon the core competencies, both of which are close to their main business, namely alcohol beverage business. At the same time, other large international beer brewers such as Anheuser-Busch, Heineken, and Lion Nathan, are pursuing a different strategy from the Japanese companies: these competitors are focusing even more on their core beer business. I will explore future strategies for the alcoholic beverage companies.(cont.) I will compare Japanese companies that have diversified their business including the historical backgrounds of diversification and future strategies of other international players. Subsequently, the thesis narrows down to diversification strategies for a Japanese brewing company, Kirin Brewery, which is trying to nurture another pillar for its future growth after almost 30 years of diversification. To evaluate the long- and mid-term business strategies of this new pillar--health foods and functional foods-as a new joint venture, I will apply in some detail the Delta Model Integrated Business Framework proposed by Arnoldo Hax.by Toru Yoshimura.M.B.A
