An advisor on USGBC's Board of Governing Council, her sustainability directives have achieved LEED silver and LEED gold certifications in buildings over 250,000 SF
Abstract:
Commissioning for Net Zero Energy Management is important, due to stringent code requirements and standards, e.g., IECC 2015, ASHRAE 90.1 2016, IGCC, and USGBC LEED; rising costs of electricity; and the Federal Government Net Zero Mandate. Clients are requiring net zero energy for new and, in some cases, existing construction. Buildings are the largest energy consumer in the USA, consuming approximately 40% of primary energy, 72% of electricity, and 55% of natural gas. Commissioning for Net Zero Energy Management is generally consistent with an Energy Use Intensity (EUI) goal mindset, where the building is commissioned for performance. A portion of energy usage can typically be provided with sustainable energy technologies. This keynote will present the differences between traditional Commissioning and Commissioning for Net Zero Energy Management, discuss the challenges in its implementation, and present a number of case studies.

Keynote: Sustainable energy production from natural water resources by sulfide driven fuel cell
Biography:
V Beschkov, PhD, DSc has got his PhD and his DSc degree from the Bulgarian Academy of Sciences. His present interests are chemical and biochemical processes for environment protection and utilization of renewable energy sources. He participated in 30 scientific projects and in 19 applied ones. The most important project he has been working on is “Hydrogen Production from Black Sea Water by Sulfide-Driven Fuel Cell”, financed by the FP7. He published over 200 scientific papers, monographs and chapters in selected issues. Over 1300 citations of his papers have been noted (h-index=20).
Abstract:
Hydrogen sulfide is frequently present in natural waters, like mineral springs, but mostly it is found in marine water with low renewal rate. The Black Sea is the water pond with extremely high hydrogen sulfide content, estimated to some 4.6 Gt, thus increasing in time. The utilization of this enormous amount could be accomplished in different ways, but the most promising is its direct conversion into electricity. This result can be attained by sulfide driven fuel cell (SDFC), converting sulfide to sulfate thus releasing up to 26 GJ/t. This work presents experimental data in laboratory scale SDFC for sulfide conversion into sulfate, sulfite and polysulfide releasing different amounts of electric energy. Experiments are carried out at initial sulfide concentrations from 10 to 300 mg/l. Sulfate, sulfite and polysulfide ions are detected in the outlet solutions from the fuel cell. The quantitative results showed good agreement with the chemical analyses. Most of the results showed attained high efficiencies of the fuel cell, i.e. up to 80%. The next efforts will be dedicated to attainment of high current and power densities suitable for direct practical applications. The practical applications of this method could be extended to other purposes, like treatment of polluted water together with utilization as energy.

Abstract:
Solar radiation (~0.2–2.5 µm) on earth surface involves illumination and heat generation as it covers the electromagnetic waves of visible and near-IR region. The Air Mass (AM) spectrum of solar radiation shows irradiance decreases with the increase in tilted angle. Hence, designing of window glass system should be made in such a manner that solar radiation should enter the room at high angle of incidence highlighting reasonable illumination (100–300 lux) and suitable thermal comfort. To remove the unwanted heat absorption by glass, a suitable layer of low thermal emissivity with heat reflection property should be deposited onto the window glass. On the basis of this idea a low-e material, indium antimony oxide (IAO) (In: Sb=97:07), a wide band gap semiconductor (band gap, ~3.5 eV) has been chosen and deposited on to window glass of dimensions, 500 mm x 500 mm by soft chemistry method. The developed film is transparent in the visible and electrically conducting with >25% reflection in the Mid-IR region. The performance of the film as window glass fenestration in day time is characterized by evaluating direct solar optical properties from the spectral data measured at different angles of incidence by UV–VIS–NIR spectroscopy. Major work was executed at CSIR-CGCRI, India in collaboration with the School of Energy Studies, Jadavpur University, and Kolkata, India. The outcome of the work is prospective and this will be discussed in the talk.

Abstract:
Steady penetration of solar and wind energy into US electric generation has brought significant changes to the industry. This has happened at a time when natural gas remains abundant and inexpensive. In fact, gas turbines running on natural gas are quite often touted as renewable-enabler as their fast start-up characteristics make them ideal for meeting grid demands when generation from solar and wind energies fall off. The combination of enhanced electric grid and back-up power generation would work nicely, except that carbon dioxide would still be emitted while using the back-up power generation. Of course, that can change when affordable, grid-scale battery storage is available. This presentation covers two different power production scenarios, where direct solar electricity generation can be complemented by alternative modes of power generation such that no carbon dioxide gets released to the atmosphere even when natural gas is used to complement the renewable generation. The first scenario covers solar thermal power generation hybridized with super-critical carbon dioxide (sCO2) power cycle with oxy-combustion of natural gas. Here, carbon dioxide will be naturally captured even when natural gas is used as the heat source, and in addition, water will be produced in the oxy-combustion process that will be available for consumption. The second scenario involves solar PV array to be complemented by a salinity-gradient-solar-pond (SGSP) that acts as a thermal storage to store the solar energy when available. When sun is not shining, stored thermal energy is converted to electricity through an Organic Rankine Cycle.

Abstract:
Reduced-order beholder for rotor flux estimation of generalization motor s are considered. The “electric current” model and “voltage” model are obtained as special cases. It is shown that the flux dynamics variant a nonlinear closed-loop scheme when the flux estimate is used for study orientation course. The beholder increase survival of the fittest is extremely critical for goodness behavior of this system. A human body work is developed, in which the dimension of any gain selection easily can be assessed. Four candidates gain selections are considered, two of which proceeds schemes that do not use the rotor speed in their equations (inherently sensor less schemes). It is also shown that for any gain selection, an equivalent synchronous-frame implementation (i.e., indirect field orientation) always exists. Forefinger Terms—Field orientation, flux estimation, generalization motor, senseless control. Induction machines (IMs), unlike synchronous machines, do not allow the flux position to be easily measured. For vector control, one must resort to flux estimation. The “current” model (CM) and “voltage” model (VM) are the traditional solutions, and their benefits and drawbacks are well known. (Due to their respective parameter sensitivities, they are useful at low and nominal speeds, respectively.) Various observers for flux estimation were analyzed in the pioneering work by Verghese and Sanders. Over the years, several other have been presented, many of which also include speed estimation.

Biography:
Rahwa Gebre Tesfahuney is working as an assistant professor in institute of Environment, Gender and Development Studies in Mekelle University, Ethiopia. She did her MSc in consumers Studies-Marketing and Consumer Behavior in Wageningen University.
Abstract:
Biogas has micro and macro benefits which require sound investigation. Hence, this study was to assess costs and benefits of biogas at household level in three Weredas of Tigray in which the project is widely adopted. The study used both primary via questionnaire and secondary data from literatures. The sample size included 150 households selected via purposive sampling. The collected data were analyzed using cross tab with phi and Cramer’s value and spear man rho’s correlation. Most of the Female household heads that live in rural areas with no access to electricity and other modern alternative sources of energy are using Biogas. The size of digester of the biogas ranges from 6 meter cubic to 8 meter cubic. 6 meter cubic is common at household level. The total construction costs of biogas ranges from ETB 12,300 to 14,000 out of which only ETB 2,300 to 3,500 is covered by the users and remaining is covered by Government Organizations and NGOs. Biogas is used for lighting; baking; Boiling; cooking; and coffee making activities at household level. Location, owing cattle, feeding way of cattle, source of income and subsidy are main decision elements for adoption of biogas. Sustainable waste management, saving cooking and cleaning time, fertilizer production, saving kerosene and labor are benefits which differ as per size of digester of biogas. The benefiting capacity increases as size of digester of the biogas increases. The Biogas users are obtaining benefits while facing problems of biogas and its slurry. All concerned bodies need to give attention to female household heads in rural areas with regard to Biogas plants Development as this has a strong linkage with such part of the community and particularly the Government and NGOs need to adjust their incentives and interest rate of their loan including the Microfinance institutions to cover portion of Biogas initial cost as per the capacity and demand of the users. All stakeholders of Biogas need to focus on the decision elements and to recognize the Benefits of Biogas that differ as per the size of digester of the biogas so that to act accordingly.

Time : 15:25-15:45
Biography:
Belqasem Aljafari has completed his MS from Northern Illinois University School of Engineering. He is pursuing his education by studying currently the PhD degree school of engineering.
Abstract:
There has been concern over the commercially existing energy storage technologies over their capacities and efficiency. Supercapacitors are now being viewed as one of the most efficient energy technology alternatives. In fact, research engineers are now focusing on ways and means to boost its performance further hence it is being fortified with multi-walled carbon-based electrodes to increase its performance. This paper considers the emerging technologies and how it is shaping up the performance of electrochemical supercapacitors. Many research scientists and engineers have concentrated on the techniques and methodologies of ensuring that fortification of the supercapacitor using the multi-walled carbon nanotube material bears fruit. The investigation of correlation in characteristics between a purely made supercapacitor with ordinary carbon as a base material and that in which the multi-walled carbon nanotubes are embedded was carried out. The results obtained were positive as there was a marked improvement in the capacitive performance of the fortified supercapacitor. The carbon nanotubes provided a more significant electrode potential hence attracting more ions. In fact, the capacitance, due to this composition, jumped from four to 139F/g. Further agree that the desirable capacitive qualities in carbon nanotubes could be attributed to the fact they have higher specific surface area, greater thermal and electrical conductivity, and lower mass.

Abstract:
Current global energy systems have proven unsustainable amid effects of the cumulative greenhouse emissions and climate change. The drive towards a low carbon future has precipitated the consideration of alternative energy sources. This paper captures the complex dimensions of scaling up energy supply with specific reference to bio-derived energy production. Within this sector sugar cane, grown widely in African countries, is known to be one of the most productive species in terms of its conversion of solar energy to chemical potential energy. However the supply of feedstock is limited to the harvest or crop season. More-so the sugarcane industry is faced a plethora of threats and challenges. The spatial system dynamics model (SSDM) of sugarcane industrial ecosystem presented in this paper is towards an integrated approach to simulate a bio refinery system suggesting directions for bagasse and trash-derived electricity generation. The model unpacks the complexity in bio-derived energy generation across the conversion pathways of the system from land use change, sugarcane production, and harvesting and electricity production amid a plethora of challenges in the system. Input data for land use and sugarcane production in the model were derived from remote sensing and spatial analysis. Simulated and validated results indicate that the alternative scenario of combined bagasse and trash with enhanced mechanisation and technology efficiency provides the highest efficiency in terms of electricity generation and emission avoidance compared to the business as usual or base case scenario. The applied SSDM demonstrates that modelling of feedback-based complex dynamic processes in time and space provide better insights crucial for decision making. This model provides a foundation for the broader study for cost benefit analysis of electricity production from a sugarcane industrial ecosystem.

Title: The dynamics of cost overrun in public sector construction projects in developing countries
Time : 16:25-16:45
Biography:

He has over ten years of experience in the Ghanaian Construction Industry with specialty in Construction Management and Quantity Surveying. He is a Senior Lecturer at the Koforidua Technical University and an Associate Member of the Ghana Institution of Surveyors. He can presently refer to a list of journal and conference papers
Abstract:
Cost overrun of projects has been a key concern for all stakeholders of projects for many decades now. However, the empirical evidence of the causes seem not be clear due to the silo approach in understanding the causes of project cost overrun. This study seeks to take the debate a step forward by providing an understanding of the causes of project cost overrun from a system’s perspective, especially from a less researched environment. Data was collected and analyzed from 131 respondents who were mainly involved in construction works in public procurement entities in Ghana. A two-staged approach was employed in collecting data from the respondents. The first stage involved an interview session with key informants in the construction industry in Ghana to ascertain the detailed causes of cost overrun of construction projects. The second stage focused on the validation of these detailed factors by a wider stakeholder group through questionnaires. Factor analysis was employed to consolidate these detailed factors into some main causes of project cost overrun. The results show that there are primarily four major causes of most public sector projects cost overrun. These four major causes of cost overruns are poor contract planning and supervision; change orders; lack of competence of the project team and lack of effective coordination among the contracting parties. The study sheds light on areas where public sector project planners and managers should focus on in order to alleviate projects cost overrun. In other words, it serves as a decision support system for planners and managers of public sector projects in effectively managing the challenge of projects cost overrun. The study provides more insights as to the critical factors that underpin public sector projects cost overrun and more importantly does so from a system’s perspective

Abstract:
With the rapid growth of battery technologies in renewable energy production, it is essential to understand the battery type and the model, to achieve a coordinated control. The research provides the grid-connected battery modeling that integrates wind. The advanced battery model utilizes the electrical equivalent (dual polarization) model for the analysis. The research involves deploying a 1 MWh energy storage system (at Reese Technology Center in Lubbock, Texas) to understand the renewable energy sources and load management, including battery applications such as ramp control, frequency response, voltage response, emergency backup and peak load leveling, when connected to the grid. In order to develop the test bed of the grid-connected battery project at Reese, the research provides the simulation results using PSCAD software on discharge and charge characteristics of the 1 MWh Lithium Manganese Oxide battery under transient fault conditions when it is tied to the grid for wind integration. Initially vector control technique was used to control the current flow and the results were validated using the experimental data. Later an emerging technique on model predictive control (for three phase bi-directional converter to integrate a battery system with the grid) was developed to compare its performance with the vector controller. The model predictive control technique is analyzed to integrate the 1MWh battery system in PSCAD simulation environment for both steady state and fault scenarios. The simulation results show the effectiveness of model predictive control technology for battery system integration with the grid.

Abstract:
A smart city is a sustainable urban center that interconnects and improves quality of life for its inhabitants which are ever increasing due to the rapid urbanization particularly in Asia. A smart city is composed of a number of components including smart buildings, smart grid, smart energy and smart transportation. Many of these components are supporting clean energy which is a promising solution to the threatening environmental problems such as pollution, carbon dioxide emission and ozone layer depletion. On the other hand, the integration and penetration of clean energy into smart cities poses challenges to the power systems that require sophisticated sensing in order to maintain power stability. Sensing is a major framework of a smart city as it gathers vital data and statistics to ensure the smooth operation of the city. Most of the smart city applications are created with the building blocks of sensors. Magnetic, being one of the six major sensor energy forms, plays an important technical role in both smart city and clean energy. Therefore smart city, clean energy and magnetic sensing form a trilateral relation that is shaping the current status as well as future prospect of smart living. In this talk we will discuss how magnetic sensing can be implemented to enable smart city with clean energy. We will look at the latest development of applications of magnetic sensors in smart city and clean energy. An overview picture of the technology trend will be presented to illustrate the contribution of magnetic sensing to sustainability and smart future.
