Abstract

The facade is part of the architectural work that must meet the elements of aesthetics, safety, and comfort. Types of modern facade materials usually consist of glass and aluminum frames. The choice of facade material greatly affects the energy consumption of a building, so that in planning the facade work it is necessary to determine the performance of the material. This study uses the value engineering analysis method which is expected to help determine the quality and performance of the best facade materials for buildings. The results of the analysis in this study can also be used as consideration for stakeholders in making decisions from the impact of initial costs and energy consumption costs to create energy efficient buildings. The case study in this study is a 9-story building in Jakarta that uses a fixed glass window wall type facade or fixed glass. This study analyzes 3 choices of glass materials, namely laminated glass, IGU glass and a combination of placement of laminated glass on the north-south side of the building and IGU glass on the east-west side. Aluminum material also has 2 types of choices, namely insulated profile and non-insulated profile. The results of the analysis show that IGU glass is superior in reducing heat energy so that the electrical energy load can be reduced with a fairly high initial cost increase of 43% of the existing design (laminated glass). However, the positive impact of IGU glass is that it provides 31% savings in the use of electrical energy in AC. Aluminum specifications between insulated and non-insulated do not have a significant impact on building energy savings in areas with two seasons such as in Indonesia. Keywords: Green Building, Architecture, Façade, Value Engineering, Energy Saving Fasad merupakan bagian dari pekerjaan arsitektur yang harus memenuhi unsur estetika, keamanan, dan kenyamanan. Jenis material fasad modern biasanya terdiri dari material kaca dan rangka aluminium. Pemilihan material fasad sangat mempengaruhi konsumsi energi pada suatu bangunan, sehingga pada perencanaan pekerjaan fasad perlu ditentukan performa materialnya. Penelitian ini menggunakan metode analisis value engineering yang diharapkan membantu menentukan kualitas dan kinerja material fasad yang terbaik untuk bangunan. Hasil analisis pada penelitian ini juga dapat digunakan sebagai bahan pertimbangan bagi stakeholder dalam mengambil keputusan dari dampak biaya awal dan biaya konsumsi energi untuk menciptakan bangunan hemat energi. Studi kasus pada penelitian ini adalah gedung 9 lantai di Jakarta yang menggunakan tipe fasad dinding jendela kaca mati atau fix glass. Penelitian ini menganalisis 3 pilihan jenis material kaca yaitu kaca laminated, kaca IGU dan kombinasi penempatan kaca laminated di sisi utaraselatan bangunan serta kaca IGU di sisi timur-barat. Material alumunium juga memiliki 2 jenis pilihan yaitu insulated profile dan non insulated profile. Hasil analisis menunjukkan bahwa kaca IGU lebih unggul dalam mereduksi energi panas sehingga beban energi listrik dapat tereduksi dengan kenaikan biaya awal yang cukup tinggi yaitu 43% dari desain existing (kaca laminated). Namun dampak positif dari kaca IGU yaitu memberikan penghematan biaya pemakaian energi listrik pada AC sebesar 31%. Spesifikasi aluminium antara insulated dan non insulated tidak memberikan dampak secara signifikan pada penghematan energi bangunan di daerah dengan dua musim seperti di indonesia.
