Abstract

The potential of water energy in Bali Province, especially in Tamblang Dam, is very high and can be utilized to provide energy needs in the surrounding area. On the other side, the Buleleng Regency Government took the initiative to develop tourism potential by planning a green tourism-based Tourism Destination Area (DTW), which utilizes renewable energy as a supporting component. One of the renewable energy potentials that can be utilized in Tamblang Dam is Micro Hydro Power Plant (PLTMH), which is designed with a designed flow rate of 2.21 m3/s with a capacity of 1.2 MW. The design of Micro Hydro Power Plant of Tamblang Dam requires an initial investment cost of Rp 2,434,358,091, and based on the results of economic analysis, the design of Micro Hydro Power Plant of Tamblang Dam is classified as feasible for investment, with NPV of Rp 68.6 billion, BCR 40.81, and PP less than 10 years.

Abstract

Green building retrofit is an approach that involves modifying or enhancing existing buildings to achieve higher standards of sustainability and energy efficiency. By conducting an energy audit first, it's possible to identify potential energy savings in the housing, as well as components that need to be upgraded to reach the desired level of sustainability. Retrofit solutions may include the use of implementation of efficient HVAC systems, energy-saving lighting, and better energy management. The aim of this research is to explore the potential improvements that can be applied through Green Building Retrofit with a focus on energy efficiency and sustainability in Jadi Pesona II Barat Housing, comparing the energy consumption conditions of houses before and after the energy audit, as well as calculating the payback period for occupants after the retrofit implementation. After the energy audit and Green Building Retrofit, daily energy usage in homes in Perumahan Jadi Pesona II Barat decreased from 47.45 kWh per day to 36.91 kWh per day. This indicates a reduction of 10.54 kWh per day or approximately 22.22% from the previous conditions, and the payback period analysis results show that almost all air conditioners show values in line with the project investment feasibility parameter, which is below 4.2 years.
