Perancangan Green Office Berdasarkan Kajian Studi Kasus di Kantor Proyek Pembangunan Gedung Rumah Sakit

Abstract

Kantor proyek merupakan fasilitas sementara yang mendukung kegiatan konstruksi, tetapi umumnya belum menerapkan prinsip keberlanjutan. Penelitian ini bertujuan menilai penerapan prinsip green office pada kantor proyek pembangunan gedung rumah sakit berdasarkan parameter Bangunan Gedung Hijau sesuai Peraturan Menteri PUPR Nomor 21 Tahun 2021 serta menyusun rekomendasi perancangan untuk meningkatkan kinerja lingkungan bangunan. Data diperoleh melalui observasi, pengukuran teknis, kuesioner, dan wawancara, kemudian dianalisis secara deskriptif-komparatif, analisis kesenjangan, serta simulasi menggunakan aplikasi EDGE (Excellence in Design for Greater Efficiencies). Hasil penilaian menunjukkan bangunan memperoleh 59 dari 165 poin (35,76%), masih di bawah batas peringkat Pratama (45%), dengan kesenjangan terbesar pada efisiensi energi, pengelolaan tapak, dan efisiensi air. Rekomendasi meliputi penambahan ruang terbuka hijau, penggunaan AC inverter, occupancy sensor, meter air, sistem rainwater harvesting dan grey water recycling, serta air purifier dan tanaman indoor. Simulasi EDGE meningkatkan nilai kinerja menjadi 52,12% sehingga mencapai peringkat Pratama.

Project offices are temporary facilities that support construction activities, but generally do not yet implement sustainability principles. This study aims to assess the application of green office principles in hospital building construction project offices based on Green Building parameters as stipulated in Minister of Public Works and Public Housing Regulation Number 21 of 2021 and to develop design recommendations to improve the building's environmental performance. Data were obtained through observation, technical measurements, questionnaires, and interviews, then analyzed descriptively and comparatively, gap analysis, and simulation using the EDGE (Excellence in Design for Greater Efficiencies) application. The assessment results showed the building obtained 59 out of 165 points (35.76%), still below the Pratama rating limit (45%), with the largest gaps in energy efficiency, site management, and water efficiency. Recommendations include the addition of green open space, the use of inverter air conditioners, occupancy sensors, water meters, rainwater harvesting and greywater recycling systems, as well as air purifiers and indoor plants. The EDGE simulation increased the performance score to 52.12%, achieving a Pratama rating.
