Berlimpahnya cahaya matahari juga dapat membantu penghematan energi untuk pencahayaan pada bangunan kantor. Namun, cahaya matahari yang berlebih menimbulkan silau dan panas terutama pada area di dekat jendela. Fasad kaca pada bangunan kantor mempengaruhi intensitas pencahayaan alami yang masuk ke dalam ruangan sehingga digunakan shading untuk mengatur pencahayaan. Namun, shading yang digunakan saat ini bersifat statis dalam bentuk horizontal, vertikal, maupun egg crate sehingga distribusi cahaya tidak merata. Dengan demikian, penggunaan dynamic shading perlu dieksplorasi karena kemampuannya dalam mengontrol cahaya dan mengurangi konsumsi energi pencahayaan. Penelitian ini bertujuan untuk mengembangkan jenis shading melalui konfigurasi dynamic shading untuk meningkatkan kualitas pencahayaan alami sehingga menurunkan konsumsi energi untuk pencahayaan. Penelitian terdiri atas lima tahap yang diawali dengan observasi lapangan pada tujuh bangunan kantor yang dipilih. Kemudian dilanjutkan dengan pra simulasi dan perhitungan OTTV untuk memilih satu bangunan kantor yang paling tepat untuk dipasang dynamic shading. Tahap berikutnya adalah simulasi eksisting dan modifikasi shading horizontal, vertikal, dan egg crate yang masing – masing memiliki konfigurasi fasad berbeda karena jenis rotasi yang berbeda pada fasad. Tahap selanjutnya yaitu pengukuran pencahayaan alami di bangunan terpilih dan tahap terakhir yaitu eksperimen. Lebar kisi – kisi dynamic shading, jarak dynamic shading ke kaca serta ukuran perforated aluminium adalah parameter penelitian. Hasil yang paling optimal untuk mencapai uniformity minimal 0,5 adalah dynamic shading egg crate dengan model 2 untuk pagi hari, model 1 untuk siang hari, dan model 3 untuk digunakan pada sore hari. ......The quantity of sunlight can also assist save electricity for office lighting. Excessive sunshine, on the other hand, generates glare and heat, particularly in places near windows. Because glass facades in office buildings modify the intensity of natural light entering the space, shading is used to control illumination. However, the shading currently used is static in the form of horizontal, vertical, or egg crates so that the light distribution is uneven. Thus, the use of dynamic shading needs to be explored because of its ability to control light and reduce lighting energy consumption. This study aims to develop types of shading through dynamic shading configurations to improve the quality of natural lighting thereby reducing energy consumption for lighting. The research consisted of five stages beginning with field observations in the seven selected office buildings. Then proceed with the pre-simulation and OTTV calculations to choose the most appropriate office building to install dynamic shading. The following stage involves the existing simulation and modification of the horizontal, vertical, and egg crate shading, each of which has a different facade configuration due to a different sort of facade rotation. The following stage is to measure natural illumination in selected buildings, followed by experiment of the best dynamic shading configuration. The research parameters are the width of the dynamic shading grating, the distance between the dynamic shading and the glass, and the size of the perforated aluminum. The dynamic shading of egg crate with model 2 for the morning, model 1 for the afternoon, and model 3 for use in the afternoon produces the best results for achieving uniformity of at least 0.5.

Konsep Nearly Zero Energy Building merupakan salah satu aspek kunci dalam menghadapi tantangan lingkungan global saat ini. Gedung X yang berlokasi di Jakarta Selatan selama tahun 2022 konsumsi energinya termasuk dalam kategori agak boros sehingga masih perlu dilakukan implementasi Nearly Zero Energy Building. Pengambilan data dilakukan dengan pengukuran langsung konsumsi energi untuk tiap klasifikasi peralatan listrik, kemudian dipilih alteranif investasi untuk pengemahatan konsumsi energinya. Penelitian ini bertujuan untuk memperoleh potensi penghematan dan produksi energi pada Gedung X yang dapat diterapkan. Terdapat empat alternatif strategi yaitu Penggantian Cooling Tower dan Pompa CWP, instalasi BAS, Penggantian LED Dim Light, Instalasi Panel Surya, semuanya mengahasilkan NPV yang positif kecuali Instalasi Panel Surya. Alternatif instalasi panel surya memakan biaya investasi yang paling mahal dan menghasilkan NPV yang negatif, seluruh kombinasi investasi yang melibatkan instalasi panel surya akan menghasilkan NPV yang negatif, sehinga penerapan NZEB dengan investasi panel surya disimpulkan tidak layak di Gedung X. Selanjutnya Kombinasi penggantian cooling tower & pompa CWP, Instlasi BAS, dan Penggantian LED Dim Light menghasilkan nilai paling baguns dibanding skenario lain yaitu pengembalian NPV Rp 437,853,822, penurunan IKE sebesar 11.76 menjadi “efisien’ dan penurunan emisi karbon sebesar 1,172,648 (kg CO2/kWh). ......The Nearly Zero Energy Building concept is one of the key aspects in facing current global environmental challenges. Building Data collection is carried out by directly measuring energy consumption for each classification of electrical equipment, then investment alternatives are selected to reduce energy consumption. This research aims to obtain the potential for energy savings and production in Building X that can be implemented. There are four alternative strategies, namely Cooling Tower and CWP Pump Replacement, BAS installation, LED Dim Light Replacement, Solar Panel Installation, all of which produce a positive NPV except Solar Panel Installation. The alternative of installing solar panels requires the most expensive investment costs and produces a negative NPV, all investment combinations involving solar panel installation will produce a negative NPV, so that the implementation of NZEB with solar panel investment is concluded to be unfeasible in Building X. Furthermore, the combination of replacing the cooling tower & CWP pump, BAS installation, and LED dim light replacement produced the best value compared to other scenarios, namely NPV return of IDR 437,853,822, IKE reduction of 11.76 to "efficient" and reduction of carbon emissions of 1,172,648 (kg CO2/kWh).

The Fire damage occurs in unpredictable time and can cause losses to the owner because of the damage. It can occur in buildings that do not have Fire Protection and Fire Safety Management System in the building. By detecting and preventing against fire damage, which arise in unpredictable times will prevent loss of lives and assets of the buildings. There has been considerable research into the fire damage such as at the Polo Condominium in Colorado. The Polo Condominium that was built in 1967 caught fire on October 31' because it did not have the Fire Protection System in each floor. When the fire came and burned the building interior, the building could not extinguish the fire because it did not have fire detector and sprinklers in place. To solve the problem, in Jakarta there are a lot of guidelines such as the Minister Of Public Works Decree # 02IKPTSI1985 for Fire Safety in building. But from many fire damages, the guidelines could not accommodate the problem because the buildings did not incorporate Fire Protection and Fire Safety Management System. Relevant research indicated that Fire Protection and Fire Safety Management System are very important to detect and prevent against fire damage. In this research, the Fire Protection and Fire Safety Management System are defined as Fire Safety Design which have been taken from many relevant theories and journals. From 50 questionnaires sent to various high rise office buildings in Jakarta, 30 responses were received to be viable for in depth analysis. The result of the analysis shows clearly that the Fire Safety Design is positively correlated in a linear manner to four of the key Fire Safety Design variables. The four key variables influencing building reliability in design carried out by the consultant and controlled by the construction manager in the projects are : detection and fire alarm, building architecture, the designer's fire certificate and special equipment to stop fire_ This research can then be used to control and measure the quality of Future Fire Safety Design of the high rise building reliability in Jakarta.
