Abstract: The Simpang Lima area is a city center with a variety of activities, the center of circulation, publik space, green space, religion, sports, economy, social and culture. In the regulation of vehicle and human circulation sistems it is very important and requires an impact analysis as well as very long projections. The intersection of five Semarang City known as the center of the economic area as well as the green open space that used as a publik space so that many activities and activities that occur in the area. In addition to being a business district and office intersection, there is also a weekly car free day event, becoming a very large center of activity on Sundays and a publik space in Semarang.The influence of the five intersections in this area will focus on humans who are in front of the five intersection (ciputra mall stop) with the intersection of five because the location is the number of people passing through more roads. So in this study two recommendations will emerge, the first of which relates to humans who crossed at one point, the second is recommendations for the entire region.Keyword: Circulation, Pedestrian, ConnectivityAbstrak: Kawasan Simpang Lima merupakan pusat kota yang terdapat berbagai macam kegiatan, pusat sirkulasi, ruang publik, ruang hijau, agama, olahraga, ekonomi, sosial dan budaya. Dalam pengaturan sistem sirkulasi kendaraan maupun manusia sangatlah penting dan memerlukan suatu analisa dampak juga proyeksi yang sangat panjang. Simpang lima Kota Semarang diketahui sebagai pusat kawasan ekonomi maupun ruang terbuka hijau yang dijadikan ruang publik sehingga banyak kegiatan dan aktifitas yang terjadi dikawasan tersebut. Selain menjadi kawasan bisnis dan perkantoran simpang lima juga terdapat event mingguan car free day, menjadi pusat aktifitas yang sangat besar pada saat hari minggu dan menjadi ruang publik di kota semarang. Pengaruh simpang lima pada kawasan ini akan focus terhadap manusia yang berada di depan simpang lima (halte ciputra mall) dengan lapangan simpang lima tersebut karena pada lokasi tersbut jumlah manusia yang melewati jalanlebih banyak. Maka dalam penelitian ini akan muncul dua rekomendasi, yang pertama terkait manusia yang menyebrang pada datu titik tersebut, yang kedua rekomendasi seluruh kawasan.Kata Kunci: Sirkulasi, Pedestrian, Koneksitas

Abstract

Energy Use Intensity (EUI) is a key indicator for evaluating the energy efficiency of buildings. This study aims to analyze the EUI factors in two government office buildings: the Ministerial Office (MO) building and the Directorate General of Water Resources (DGWR) building of The Ministry of Public Works. Both are located in close proximity and share similar physical characteristics under tropical climate. The EUI is analyzed using the walkthrough audit method as a practical approach for assessing energy performance. The results show that the DGWR Building exhibits higher energy consumption, primarily due to the dominance of cooling loads accounting for 54.13% of the total EUI, compared to 46.54% at the MO building.  There are three main factors contributing to the EUI variation include: (i) heating, ventilation, and air conditioning (HVAC) system – the water-cooled chiller used in the MO building shows higher efficiency compared to the air-cooled chiller system installed in the DGWR building; (ii) Overall Thermal Transfer Value (OTTV) – although both buildings utilize similar envelope materials, the OTTV value in DGWR building is significantly higher due to its larger window-to-wall ratio (WWR), which increases heat gain through the facade; and (iii) Lighting – while there is no significant difference in total installed lighting power, the higher lighting power density (LPD) in DGWR building contributes to a greater lighting energy load per unit area. Additionally, the implementation of smart lighting systems in MO building contributes to better energy efficiency performance.
