The Impact

This paper focuses on the impact of Solar Water Heaters (SWH) at a higher institution of learning. An energy audit was conducted for the evaluation of the energy conservation measure: energy conoduction Energy is a key element in the development of any country or institution; as a result any shortage in energy will have a serious effect on the economy and social aspect of such country or institution. South Africa has, in recent years, experienced high economic growth as well as a rapid expansion in the elsumption analysis, correlation of consumption with weather; financial criteria, payback period and needed solar heater system (SWH) to determine the energy that may be termed as wastage or can be saved. The method of investigation includes assessment of the hot water usage within the institution campus and residencies, analysis of bills, metering and development of a software model for the analysis of energy use, system needed and environmental variables. This renewable measure (SWH) showed a high potential of energy and financial savings for higher education institutions especially those with residences.

The Impact

South Africa experienced a rapid expansion in the electric power consumer base after 1994 that was not matched by corresponding investment in the country’s generation capacity. By the dawn of 2008, the situation had reached a critical point, with regular countrywide blackouts and load shedding and is expected to persist for several years, before the proposed new base stations can come online. Currently, 92% of the country’s electricity is generated in coal-based power stations and are responsible for the country’s heavy carbon footprint. Additionally this power must crisscross the country to distant load centres via an aging transmission infrastructure and in the process massive amounts of energy are lost particularly during peak power demand. Electricity consumption in South African households accounts for approximately 35% of peak demand, with water heating constituting 40% of that. The country has abundant sunshine and solar water heating technology and offers one of the most viable compiementary solutions to the country’s energy and environmental crises. Moreover the location of the systems at the consumer end means that the need to upgrade the transmission infrastructure can also be differed.Application of technology alone however, may not necessarily result in the required energy savings particularly in cases of uninformed consumer usage. In this paper the authors evaluate the impact of consumer behaviour on the performance of domestic solar water heaters in South Africa and suggest measures that could be taken to optimize this performance.

Abstrak: Kebiasaan manusia berubah karena adanya wabah COVID-19, hal ini berpengaruh ketika manusia masuk ke dalam fase new normal. New normal diartikan sebagai keadaan yang tidak biasa dilakukan sebelumnya, yang kemudian dijadikan sebagai standar atau kebiasaan baru yang mesti dilakukan manusia untuk dirinya sendiri maupun untuk bersosialisasi dengan orang lain. Kebiasaan baru ini pun menimbulkan pro dan kontra seiring dengan dampak yang timbul. Lembaga pendidikan tinggi merupakan salah satu yang merasakan dampak penerapan new normal. Perkuliahan yang selama ini dilakukan secara online/daring, akan kembali dilakukan secara luring/tatap muka, dengan tetap menerapkan protokol COVID-19 seperti mengenakan masker, menjaga jarak, mengenakan sarung tangan, serta tidak melakukan kontak fisik seperti berjabat tangan. Masalah yang muncul bukan hanya kecemasan orang tua terhadap anak – anaknya, tetapi bagaimana lembaga pendidikan tinggi mengatur segala sumber daya yang dimiliki agar memenuhi standar penerapan new normal. penelitian ini bertujuan untuk mengetahui penerimaan  terhadap kondisi normal yang baru menggunakan Perspektif balance score card. Abstract: Human habits change because of the COVID-19 outbreak, this affects when humans enter the new normal phase. New normal is defined as a condition that is not normally done before, which is then used as a standard or new habits that must be done by humans for themselves or to socialize with others. This new habit also raises the pros and cons along with the impact arising with the new normal. Higher education institutions are the ones who feel the impact of implementing new normal. Lectures that have been conducted online / online will be re-done offline / face to face, while still applying the COVID-19 protocol such as wearing a mask, keeping a distance, wearing gloves, and not making physical contact such as shaking hands. The problem that arises is not only parents' anxiety about their children, but how higher education institutions regulate all available resources to meet new normal implementation standards. This study aims to determine acceptance of new normal conditions using the balance score card Perspective.

Building America (BA) partner McStain Neighborhoods built the Discovery House in Loveland, CO, with an extensive package of energy-efficient features, including a high-performance envelope, efficient mechanical systems, a solar water heater integrated with the space-heating system, a heat-recovery ventilator (HRV), and ENERGY STAR appliances. The National Renewable Energy Laboratory (NREL) and Building Science Consortium conducted short-term field-testing and building energy simulations to evaluate the performance of the house. These evaluations are utilized by BA to improve future prototype designs and to identify critical research needs. The Discovery House building envelope and ducts were very tight under normal operating conditions. The HRV provided fresh air at a rate of about 35L∕s(75cfm), consistent with the recommendations of ASHRAE Standard 62.2. The solar hot water system is expected to meet the bulk of the domestic hot water (DHW) load (>83%), but only about 12% of the space-heating load. DOE-2.2 simulations predict whole-house source energy savings of 54% compared to the BA Benchmark (Hendron, R., 2005 NREL Report No. 37529, NREL, Golden, CO). The largest contributors to energy savings beyond McStain’s standard practice are the solar water heater, HRV, improved air distribution, high-efficiency boiler, and compact fluorescent lighting package.

The Impact

PurposeDespite the significance, university student start-ups and student entrepreneurship ecosystems (SEEs) have been subject to little research. This study aims to apply a qualitative emergent enquiry approach to explore best practice SEEs in Australia, complimented by narratives from leading scholars in higher education institutions with the aim of delineating the integrative components of SEEs.Design/methodology/approachAdopting the entrepreneurial ecosystem framework and aligned to the social cognitive theory, this paper explores the components and dynamics of SEEs, contributing to an understanding of how such components can better support the growth, sustainability and success of student start-ups. The authors extend entrepreneurship research on social construction using narrative research.FindingsThe findings provide guidelines for researchers, entrepreneurship scholars and educators, entrepreneurship students, policymakers and practitioners to enhance the impact and success of university student start-ups by adopting a student ecosystem approach.Research limitations/implicationsThe narratives represent a limited number of universities with an opportunity for further research to empirically measure the impact and outcomes of SEEs. The research is exploratory, inherently conceptual and emergent, providing an opportunity for validation of narrative frameworks in future studies.Practical implicationsThe findings may assist university managers to be more aware of their own subconscious preferences to student entrepreneurship and start-up initiatives, which may be useful in refining their impact and offerings regarding a quest toward the entrepreneurial university.Social implicationsFrom social perspectives, the alignment of the components of SEE has the ability to enhance and shift the entrepreneurial mindset of entrepreneurship students, notwithstanding enhancement of intentionality and self-efficacy.Originality/valueThis is the first study of SEEs in Australia, highlighting the importance of the integration of entrepreneurship education programs, entrepreneurship education ecosystems, the entrepreneurial university and specific start-up initiatives such as university accelerators. Furthermore, students may enhance their entrepreneurial mindset by actively engaging in such ecosystems.

The Impact

This study examines the impact of energy management and productivity-enhancing measures, implemented as part of LEED Existing Buildings Operations and Management (EBOM) certification, on source energy use intensity and rental premiums of office spaces using data on four major US markets. Energy management practices, comprised of commissioning and advanced metering, may reduce energy usage. Conversely, improving air quality and occupant comfort in an effort to increase worker productivity may in turn lead to higher overall energy consumption. The willingness to pay for these features in rental office buildings is hypothesised to depend not only on the extent to which productivity gains enhance the profits of a commercial tenant but also on the lease arrangements for passing any energy savings to the tenant. We apply a difference-in-differences method at a LEED EBOM certification group level and a multi-level modelling approach with a panel data structure. The results indicate that energy management and indoor environment practices have the expected effect on energy consumption as described above. However, the magnitude of the achieved rental premiums appears to be independent of the lease type.

The Impact

COVID-19 has disrupted not only human lives but also the quality of education especially in developing countries of the South- Asian region. This study elaborates the impact of COVID-19 on education sector and also illustrate the strategies followed by the management of Higher Education Institutions (HEIs). The systematic review of 23 most relevant research studies shows that the Pandemic has affected students� learning, mental, physical, social and economical conditions badly. Particularly, students who do not afford the use of technological appliances are suffering more. HEIs need to have a smart online syllabus for various subjects. Furthermore, HEIs need to review their communication channel and technical assistance. The strategies implemented by HEIs during COVID-19 are useful and should be continued to keep offering quality education during upcoming academic sessions.
