“…Ruang yang telah dirancang tidak dapat memenuhi fungsinya dengan baik apabila tidak disediakan akses pencahayaan (Kong & Jakubiec, 2021). Penggunaan sistem pencahayaan yang tidak efektif dan efisien dapat menurunkan produktifitas, kenyamanan, dan menyebabkan pemborosan (Belany et al, 2021;Cho et al, 2020).…”

Hingga tulisan ini disusun, pandemi COVID-19 masih terus berlangsung, sementara proses pembelajaran harus terus berjalan, termasuk juga praktikum. Oleh karena itu, penelitian ini bertujuan untuk mengukur tingkat akurasi percobaan yang dilakukan secara mandiri dengan studi kasus pada pengukuran kuat terang cahaya. Metode yang digunakan yaitu melakukan pengukuran terhadap 2 sumber cahaya yaitu lilin dan senter handphone yang dilakukan pada variasi jarak 15 cm, 30 cm dan 45 cm, dengan menggunakan aplikasi smart lux meter. Hasil penelitian dibandingkan dengan rumus kuat penerangan yang sudah standar. Hasil penelitian menunjukkan bahwa percobaan yang dilakukan secara mandiri, dengan menggunakan aplikasi yang ada pada smartphone, mempunyai tingkat akurasi yang tinggi, dengan nilai akurasi pengukuran kuat terang cahaya lilin dan cahaya senter handphone masing-masing sebesar 84,05% dan 83,32%. Oleh karena itu, dapat disimpulkan bahwa percobaan yang dilakukan secara mandiri dengan menggunakan aplikasi smart lux meter mempunyai tingkat akurasi yang tinggi dan dapat digunakan sebagai solusi untuk kegiatan praktikum selama pembelajaran jarak jauh.

“…Pérez-Carramiñana et al studied the influence of retrofitting building envelope components on the energy efficiency of buildings in Mediterranean climate [17]. For the indoor facilities, Belany et al investigated the retrofit of three different lighting systems and analyzed the resulting economic cost and environmental impact [18]. Mukhtar et al analyzed and summarized the energy and environmental benefits of retrofitting the existing electric heaters for hot water and ordinary air conditioners for space heating with energy-efficient alternatives [19].…”

Building retrofit is one of the most effective ways to improve the energy efficiency of buildings. Many studies on building retrofit have been done in the literature. However, the methods provided in these studies are mostly specialized, which means they are suitable for professional building project decision makers and not for ordinary building owners. As we know, the main force to promote green buildings is ordinary building owners. Therefore, this paper studies the effects of retrofitting each individual facility in a building and simulations are done using EnergyPlus to ensure the accuracy of results, thereby, providing a simple and intuitive retrofit guide for ordinary building owners. Through this guideline, building owners can comprehensively understand the energy and economic benefits brought by the retrofit of each individual facility in the building. Based on this, building owners can easily make appropriate retrofit plans according to their buildings' situation without paying for professional consultation.

“…The energy efficiency of an old building can be increased by applying different retrofitting methods. Thus, an energy consumption reduction generated by any type of initiative (changes of the building envelope [2], changes of the lighting [3], heating systems of the building [4]) is translated to them into lower operation and maintenance costs.…”

Thermal performance analysis and the peak loads calculation of a building offer very important information in the design process and the implementation of a heating system. The paper presents the model developed to evaluate a building located in the campus of a university. The existing heating system of the building based on fossil fuels will be replaced by two geothermal heat pumps. The result of this study is the starting point of the heat pumps design process. A part of the thermal energy generated by the two heat pumps with a total heating capacity overcoming the heating peak load of the target building will be delivered to the heat network of the university. The paper also emphasizes a comparison between the results of a study carried out with TRNSYS software and results obtained within a study performed with Design Builder.
