Abstract

This study evaluates the energy performance of the Tower B building in Riau Province, Indonesia, based on green building assessment criteria, with a focus on energy use efficiency. The initial design showed a total energy consumption of 2,255,923 kWh/year, corresponding to an Energy Use Intensity (EUI) of 95.46 kWh/m²/year, and earned a moderate energy score of 30 out of 46. Two operational strategies were proposed to address inefficiencies: (1) reducing the number of elevator units from six to four, and (2) implementing separate grouping of luminaires based on daylight exposure. Simulation results indicated that these strategies could reduce energy consumption in the elevator system by 33% and in the lighting system by 13%, without compromising user service standards. The combined application of both measures reduced total building energy use to 1,949,861 kWh/year (EUI 82.51 kWh/m²/year), yielding a 29% overall reduction and increasing the energy efficiency score to 38. While the results are promising, further research is needed to validate implementation through sensitivity analysis, behavioral modeling, and integration into regulatory frameworks. This study highlights the potential of adaptive operational strategies in optimizing building energy performance in tropical urban contexts.

Abstract

Penelitian ini bertujuan untuk menganalisis kesetimbangan air pada Waduk Tugu, yang berfungsi sebagai sumber penyedia air baku dan air irigasi untuk daerah aliran Bendung Baru di Kabupaten Trenggalek. Pembangunan Bendung Baru memerlukan kajian kesetimbangan air untuk memastikan pemanfaatan aliran air dari Waduk Tugu secara optimal. Data sekunder yang digunakan dalam penelitian ini meliputi layout bendungan, data klimatologi, curah hujan, debit aliran, volume tampungan bendung, dan jumlah penduduk yang membutuhkan air. Analisis kesetimbangan air mencakup perhitungan debit air untuk irigasi dan kebutuhan air baku masyarakat, serta evaluasi debit evaporasi dan infiltrasi pada waduk. Hasil analisis menunjukkan estimasi kebutuhan air irigasi di daerah Bendung Baru, kebutuhan air baku untuk Kabupaten Trenggalek, serta kesetimbangan antara suplai air dari Waduk Tugu dan kapasitas tampungnya. Temuan ini memberikan gambaran penting mengenai manajemen sumber daya air di wilayah tersebut, guna mendukung kebutuhan irigasi dan pemenuhan air baku yang berkelanjutan. Kata Kunci: analisis, kebutuhan air, Waduk Tugu, kesetimbangan air, irigasi.
