The Cost

In Italy in 2020, only 15.5% of school building heritage was retrofitted from an energy and environmental point of view. In this paper, the cost-optimal method was applied to two different school buildings belonging to the same Italian cold climate zone but characterized by different structural and technological solutions. The research aims at defining the cost-effective redevelopment solution among several ones proposed to apply to this building type. At the same time, this paper provides a critical analysis of the methodology applied, highlighting deficiencies related to a not proper evaluation of environmentally friendly retrofitting measures. In a cost-effective context, the main results show that the intervention on the heating system is more convenient than the retrofitting of the envelope. The energy saving is equal to about 35% for both considered schools. Among the different proposed requalification configurations, the adoption of PV (photovoltaic) electric generation is included. In this regard, an optimization procedure was implemented in a generative design environment to maximize energy production with reference to different design parameters. As a result, a solution with south oriented PV modules with a tilt angle of 42° and arranged in 0.7 m spaced rows proved to be the most effective.

Industry Area

A 1 MW grid-connected PV system is studied and analyzed in this project using the National Renewable Energy Laboratory’s HOMER simulation software. The economic feasibility of the system in a small industry area of Malacca, Rembia in Malaysia, is investigated. The aim of the proposed PV system is to reduce the grid energy consumption and promote the use of renewable energy. In this paper, the emphasis is placed on the reduction of greenhouse gases emission. HOMER is capable of performing simulation on renewable energy systems as well as system optimization, in which, the optimization is based on the available usage data and the renewable energy data, such as solar irradiance and temperature. In addition, HOMER can perform sensitivity analysis according to different assumptions of uncertainty factors to determine its impact on the studied system and also the per unit energy cost. Finally, the most suitable or the best configuration system can be identified based on the requirements and constraints.

There is an increasing requirement for a cost-effective means of updating digital base map and natural resources information systems. The Northern Forestry Centre of Forestry Canada is cooperating with Alberta Forestry, Lands and Wildlife and United States agencies to evaluate ER-2 high altitude (i.e., about 20 km) reconnaissance in Alberta. A demonstration flight was arranged on 20 July 1988 to cover flight lines from Waterton Lakes National Park to Lesser Slave Lake, and return (i.e., about 1500 km). The ER-2 platform provides both the high altitude perspective of earth satellite systems and the flexibilities of aircraft. The demonstration flight carried a panoramic camera, two mapping cameras and a digital scanner that were operated simultaneously. This provided rapid, high resolution and stereoscopic coverage of large areas. The savings from improved efficiencies for base map revisions alone, using one mapping camera were greater than the costs of routine ER-2 operations over Alberta. The three other selectable sensors would also permit natural resources information system updates for only the costs of processing, interpretation and data entry. These high altitude capabilities are required for forestry in Canada.

Connectivity within Association of Southeast Asian nation (ASEAN) member countries becomes a central issue in view of the  ASEAN Economic Community 2015. However, progress towards ASEAN connectivity especially for  infrastructure developments has been limited. One of the problems is  the resource mobilization for project financing.  In recent years, rising demand for Islamic securities among global investors in jurisdictions where  legal framework and financial infrastructure are well  established has made sukuk a cost effective and  preferred  method  of raising finance.  It has also attracted liquidity to and has made Malaysia a leading  global sukuk issuer and a leading Islamic financial  hub. This paper is a case study on how Malaysia has used the Public-private partnership (PPP) for infrastructure development and how this has extended into Islamic financing  and further examines how this model can be expanded into other ASEAN member countries in particular the Cambodia, Vietnam, Laos and Myanmar  (CVLM)  countries where issues of  infrastructure financing is critical and need to be quickly resolved in view of   an enhanced ASEAN connectivity and the future of an  ASEAN community development.

Abstract This paper examines an optimized strategy and approach for executing a marginal field re-entry in the face of harsh global economic realities in the oil and gas sector. With dwindling and depressing oil prices driven by demand & supply volatility with root causes traceable to some factors such as the prevalent health pandemic, clamor for green energy, climate change discussions, geopolitics etc, the operating model for oil companies will need to drastically change to reflect current realities. Due to rapid global urbanization and increasing population amongst other factors, there is a corresponding huge appetite for oil to meet energy demands. This has led to exploration in unconventional terrains, utilization of the full extent of primary and secondary recovery mechanisms to attain high RFs in already producing fields and in some extreme cases, the development of marginal fields. In the Niger Delta area of Nigeria, marginal fields usually given up by Oil majors or abandoned following production exigencies and government laws are acquired and operated by indeginous companies. These indigenous players look for the most cost-effective means to produce these assets as it becomes the only way to make profit. A case study for field re-entry in the Niger Delta, which emphasized relatively/comparatively reduced capital outlay dependent on the technical approach is examined. Lessons learnt are drawn to aid enlightened go-forward actions and that will ensure a go-to template for similar future marginal field re-entry projects.

This study investigates the technical and cost-effective performance of options renewable energy sources to develop a green off-grid telecommunication tower to replace diesel generators in Malaysia. For this purpose, the solar, wind, pico-hydro energy, along with diesel generators, were examined to compare. In addition, the modeling of hybrid powering systems was conducted using hybrid optimization model for energy (HOMER) simulation based on techno-economic analysis to determine the optimal economically feasible system. The optimization findings showed that the hybrid high-efficiency fixed photovoltaic (PV) system with battery followed by 2 kW pico-hydropower and battery are the optimal configurations for powering off-grid telecommunication towers in Malaysia with the lowest net present cost (NPC) and cost of energy (COE). These costs of NPC and COE are more down than diesel generator costs with battery by 17.45%, 16.45%, 15.9%, and 15.5%, respectively. Furthermore, the economic evaluation of the high-efficiency solar fixed PV panels system annual cash flow compared to the diesel generator with the battery system indicated a ten-year payback period.

Abstract: The earth receives solar power at a rate of 120 petawatts, meaning that the energy obtained from the sun in a single day could satisfy the world’s energy needs for almost twenty years. Africa is often considered and referred as the "Sun continent" or the continent where the Sun's influence is the greatest, yet over 600 million people in sub-Saharan Africa live without electricity. This inexhaustible, untapped, abundant, and environmentally friendly solar energy potential encouraged solar power generation technologies to flourish faster than any other renewable energy technology most especially in Africa. The amount of electricity generated by a fixed-tilt solar PV system depends on the orientation of the PV panel (tilt and azimuth angle) relative to the sun. The panel of a solar PV system collect solar radiation more efficiently when the sun's rays are perpendicular to the panel: when the sun hits it directly at a 90o degree angle; but the sun is a moving target. Not only does it move across the sky throughout the day, but it is higher in the sky in the dry season (winter) from October to March and lower in the sky in the wet season (summer) from April to September. Since the climate is usually characterized into two seasons, the system optimization presented in this paper was carried out based on: yearly irradiation yield (fixed tilted plane) to guarantee optimum solar irradiation throughout the year, with 0.0% loss with respect to optimum. The system eliminates the challenges associated with changing the solar panel orientation every season, or using the expensive and inefficient sun tracker in tracking sun energy; while guaranteeing higher energy production, better system performance, lower system losses, and low operational cost. The system optimization was carried out with the “PVsyst simulation software” made for PV system designers and researchers to predict the performance of different solar system configurations, evaluate the results, and identify the best approach for maximum energy production. This paper investigated the optimal tilt and azimuth angle for solar panel orientation techniques for a typical rural community in Nigeria (Ndikelionwu) to advance rural electrification. After series of simulation and optimization processes; the best yearly irradiation yield was recorded when the solar panel is at 40o tilt and 0o Azimuth angle; with 0.0% loss with respect to optimum.

In many areas in the world, the high voltage (HV) electricity grid is saturated, which makes it difficult to accommodate additional solar photovoltaic (PV) systems connection requests. In this paper, different scenarios to increase the installed PV capacity in a saturated grid are assessed on the basis of the net present value (NPV). The developed scenarios compare an increase of grid capacity, PV system azimuth variation, curtailment, and battery storage. For each scenario the net present value (NPV) is assessed using an optimization model as a function of the overbuild capacity factor, which is defined as the relative amount of PV capacity added beyond the available capacity. The scenarios are applied on a case study of the Netherlands, and the analysis shows that, by optimising curtailment, a PV system’s capacity can be increased to 120% overbuild capacity. For larger overbuild capacity investments in the electricity-grid are preferred when these costs are taken into account. However, the optimum NPV lies at 40% overbuild, thus the societal and NPV optimum are not always aligned. Furthermore, the use of a battery system as an alternative to an infrastructure upgrade was not found to be a cost-effective solution. Thus, applying curtailment could be cost-efficient to a certain extent to allow for additional PV capacity to be connected to a saturated grid. Furthermore, the inverter size compared to the installed PV capacity should be significantly reduced. For a connection request that exceeds 120% overbuild increasing network capacity should be considered.

This article tackles the relationship between Turkish-Belgian families with the Flemish society, within the specific context of their experiences with early childhood education and care (ECEC) system in Flanders. Our findings are based on a focus group with mothers in the town of Beringen. The intercultural dimension of the relationships between these families and ECEC services is discussed using the Interactive Acculturation Model (IAM). The acculturation patterns are discussed under three main headlines: language acquisition, social interaction and maternal employment. Within the context of IAM, our findings point to some degree of separationism of Turkish-Belgian families, while they perceive the Flemish majority to have an assimilationist attitude. This combination suggests a conflictual type of interaction. However, both parties also display some traits of integrationism, which points to the domain-specificity of interactive acculturation.
