Abstract In the hotel business, the use of energy is very important, especially in the use of electricity, the portion of usage and allocation of funds for its provision is the largest. It can be seen that equipment such as lights, elevators, refrigerators, laundry, heaters, pumps, to the air conditioning system are some of the dominant tools in operations in the hospitality world. The results of the initial energy audit and detailed audit at the Grand Clarion Hotel Makassar showed that the Energy Consumption Intensity (IKE) is still far from the standard, which is 300 kWh / m2 a year. The building uses the largest amount of electricity in the Grand Clarion Hotel Makassar in Building A, which is in the Guest Room area of the air conditioning unit. The results of the initial energy audit of Energy Consumption Intensity (IKE) electricity were 336.84 kWh / m2 year. Whereas based on the results of a detailed energy audit the electricity consumption intensity (IKE) of electricity is 395.51 kWh / m2 a year. Energy Saving Opportunities (PHE) in this energy audit is to evaluate the AC power in each room and recommend the replacement of lamp types. From the results of the IKE calculation after the application of PHE, it is found that the value is still quite high so that efforts to save must still be done.

Urban Microclimates

This paper presents a hypothetical and comparative performance of a 5 ton air conditioner (AC) operating in two zones in different urban microclimates for 25 days. One site represents a type of homogeneous planned urbanism and the other is a traditional heterogeneous zone. Air temperature data was collected and then processed using a linear regression model included in the operating manual of the AC in order to obtain their energy consumption. Results indicate that for an area with 500 homes, a traditional urban complex requires 12,350 kWh of electrical energy more than a planned zone (1.89%). This extra energy amounts up to $1180 and adds 9191 kg of CO2 to the atmosphere. The increased energy consumption has implications that increase the cost and environmental aspects of two urban microclimates, so that urbanization without planning is less friendly to the environment. In this sense, this study highlights the effects of urban microclimates on domestic electricity consumption from air conditioning. In addition, for a city with an arid desert climate, the variation in electricity consumption is associated with changes in the urban mosaic. The results found represent scientific evidence that can be used as a reference to establish public policies that could be incorporated into the local construction regulations, oriented to reduce the energy consumption associated with the use of air conditioning equipment.

AbstractThis paper presents the results of a study that explored the effectiveness of three intervention strategies in facilitating energy saving behaviour among resident undergraduate university students. In contrast to a dominant practice of motivating with rewards or competition this study sought to appeal to students' intrinsic motivations. An experimental design was used with two intervention groups and a control group. The interventions were the provision of real-time feedback provided by an inhouse energy consumption display unit (ecoMeter) and a targeted social marketing approach. They were evaluated using energy consumption data and self-report data from the participants via an on-line survey and focus groups. Across the three research phases the rate of reduced electricity consumption for the interventions ranged from an average of 17% to 28% less than the control group. The findings provide evidence that facilitation of intrinsically motivated behaviours can result in reduced energy use and greenhouse gas emissions.

Global Action

As household incomes rise around the world and global temperatures go up, the use of air conditioning is poised to increase dramatically. Air conditioning growth is expected to be particularly strong in middle-income countries, but direct empirical evidence is scarce. In this paper we use high-quality microdata from Mexico to describe the relationship between temperature, income, and air conditioning. We describe both how electricity consumption increases with temperature given current levels of air conditioning, and how climate and income drive air conditioning adoption decisions. We then combine these estimates with predicted end-of-century temperature changes to forecast future energy consumption. Under conservative assumptions about household income, our model predicts near-universal saturation of air conditioning in all warm areas within just a few decades. Temperature increases contribute to this surge in adoption, but income growth by itself explains most of the increase. What this will mean for electricity consumption and carbon dioxide emissions depends on the pace of technological change. Continued advances in energy efficiency or the development of new cooling technologies could reduce the energy consumption impacts. Similarly, growth in low-carbon electricity generation could mitigate the increases in carbon dioxide emissions. However, the paper illustrates the enormous potential impacts in this sector, highlighting the importance of future research on adaptation and underscoring the urgent need for global action on climate change.

Consumption Practices

All over the world energy is used for different purposes and hence its continuous high demand which has brought about an increase in crisis and prices of energy. Ghana has faced a lot of supply and high electricity consumption challenges over a period of time. The Energy Commission of Ghana has developed regulations and guidelines to help reduce high consumption challenges among users, these included the replacement of incandescent bulbs with fluorescent bulbs, ban of importation of low energy efficient appliances. In spite of the effort to reduce electricity wastage, there is still a high increase in electricity consumption. The research investigated what contributed to electricity consumption in Kwame Nkrumah University of Science and Technology with the lecture halls as the main focus, the research also analyzed the current occupant behavior characterized by the electrical energy consumption practices. And investigated how the contemporary theories for reducing energy consumption was used in the lecture halls. A questionnaire survey was conducted to investigate occupants on their energy use practices in lecture halls that causes wastages, observation was made to establish relevant data on the use of contemporary theories for energy reduction in lecture halls. In a total of 110 occupants that responded to the questionnaire, 79 occupants almost always turn off electrical fitting and fixtures when not in use. From the responses, a majority of the occupants claimed to comply to best practices of energy use. The research concluded that some contemporary theories to reduce energy consumptions was not used and considered in the lecture halls.

AbstractNon-residential buildings in the European Union consume more than one third of the building sector’s total. Many non-residential buildings are owned by municipalities. This paper reports about an energy saving competition that was carried out in 91 municipal buildings in eight EU member states in 2019. For each public building an energy team was formed. The energy teams’ activities encompassed motivating changes in the energy use behaviour of employees and small investments. Two challenges added an element of gamification to the energy saving competition. To assess the success of the energy saving competition, an energy performance baseline was calculated using energy consumption data of each public building from previous years. Energy consumption in the competition year was monitored on a monthly base. After the competition the top energy savers from each country were determined by the percentage-based reduction of energy consumption compared to the baseline. On average, the buildings had an electricity and heat consumption in 2019 that was about 8 % and 7 %, respectively, lower than the baseline. As an additional data source for the evaluation, a survey among energy team members was conducted at the beginning and after the energy competition. Support from superiors, employee interest and motivation and behaviour change as assessed by energy team members show a positive, if weak or moderate, correlation with changes in electricity consumption, but not with changes in heat consumption.

Intisari — Gedung A Fakultas Teknik Unila berlokasi di Jalan S. Brojonegoro No. 1 Bandar Lampung. Penggunaan energi listrik pada gedung A ini tidak tercatat secara pasti karena memang belum tersedia kWh Meter tersendiri pada Gedung, sehingga tidak dapat dipastikan apakah penggunaan energi sudah efisien atau belum. Untuk itu perlu dilakukan audit penggunaan energi listrik guna mengetahui nilai Intensitas Konsumsi Energi (IKE) yang memberikan informasi tingkat efisiensi penggunaan energinya. Pengukuran konsumsi energi secara langsung adalah metode audit yang dilakukan pada penelitian ini untuk mendapatkan nilai aktual dan peluang dalam rangka konservasi dan efisiensi energi. Dari hasil pengukuran diperoleh nilai IKE adalah 9,487kWh/m2/bulan dan termasuk kategori efisien untuk gedung ber AC menurut Peraturan Menteri ESDM No.13 Tahun 2012, namun demikian beberapa peralatan penggunaannya masih boros energi sehingga dimungkinkan adanya peluang yang dapat dilakukan untuk menjadi lebih efisien. Rekomendasi yang diberikan berkenaan dengan hasil audit dan temuan di lapangan adalah dengan menggunakan peralatan peralatan hemat energi, mengatur suhu ruangan yang tidak melebihi 10% lebih rendah dari suhu diluar ruangan, melakukan perawatan berkala terhadap peralatan listrik, menutup jendela ketika AC sedang nyala, memasang door closer pada pintu utama serta disiplin dalam pengoperasian peralatan listrik. Rekomendasi ini dapat menurunkan nilai IKE menjadi 8,424 kwh/m2/bulan (sangat efisien).Kata kunci — Audit Energi, IKE, Bangunan Gedung FT-Unila, Efisiensi Energi Abstract — A building Faculty of Engineering Unila is located at Jalan S. Brojonegoro No. 1 Bandar Lampung. The use of electrical energy in A building is not recorded definitively because it’s not available kwh meter in building it’s own, so it can’t be ascertained whether the use of energy is efficient or not. Therefore, it is necessary to audit the use of electrical energy in order to know the value of Energy Consumption Intensity (IKE) that provides information on the level of energy efficiency. Energy audits on buildings not only provide efficient level of information, but also provide  recommendations for actions that can be taken to achieve efficient value without compromising the sense of comfort in conducting activities in the space in each audited building. Direct measurement of energy consumption is an audit method conducted in this research to obtain actual value and opportunities in the framework of energy conservation and efficiency. From the measurement obtained IKE value is 9,487kwh/m2/month and belongs to the efficient category for air-conditioned buildings according to Regulation of the Minister of Energy and Mineral Resources No.13 of 2012, but nevertheless some equipment use is still wasteful of energy so that there are possible opportunities that can be done to be more efficient. Recommendations given with regard to the results of audits and findings in the field are to use energy efficient equipment, regulate room temperature that does not exceed 10% lower than the outdoor temperature, perform periodic maintenance of electrical equipment, close windows when the air conditioner is on, install door closers on the main door and discipline in the operation of electrical equipment. This recommendation can reduce the value of IKE to 8,424 kwh/m2/month (very efficient).Keywords— Energy Audit, IKE, the building of FT-Unila, energy eficiency
