Kinmen, the famous Cold War island also known as Quemoy, is a typical island with isolated power grids. It considers the promotion of renewable energy and electric charging vehicles to be two essential strategies to achieve the goal of a low-carbon island and smart grid. With this motivation in mind, the main objective of this study is to design and deploy an energy management system for hundreds of current PV sites distributed on the island, energy storage systems, and charging stations on the island. In addition, the real-time acquisition of the data for power generation, power storage, and power consumption systems will be used for future demand and response analysis. Moreover, the accumulated dataset will also be utilized for the forecast or prediction of renewable energy generated by the PV systems or power consumed by the battery units or charging stations. The results of this study are promising since a practical, robust, and workable system and database are developed and implemented with a variety of Internet of Things (IoT), data transmission technologies, and the hybrid of on-premises and cloud servers. Users of the proposed system can remotely access the visualized data through the user-friendly web-based and Line bot interfaces seamlessly.

Quemoy University has taken over Cemetery 2 region after it was released by the military. It became the school’s other campus, with plans to change the site from an unused military camp to a sustainable campus. The finished project will include a carbon inventory of the buildings and landscape of the original camp, and overall campus planning and design. Incorporating the concept of applying GIS, the planning and survey data mentioned above will be used as the basis for the future research design and implementation. Aerial maps will be combined with cadastral and topographic maps to establish a basic evaluation resource map: a site plan map, data point map, building carbon footprint map, and route carbon footprint map. The main carbon hotspot of each building’s life cycle total carbon footprint is 549,293.14 kgCO₂e/30 yr. Through putting solar panel systems on the buildings’ rooftops and the 30 year landscape carbon inventory principle of no disturbance as the carbon offset, the unused military campus will become a zero-carbon campus. The maps above will act as carbon diagnostics for future campus operation carbon footprint analysis and provide the current situation of the campus’s environmental sustainability and future visual scenario simulations, helping decision makers to build a sustainable campus environment strategy.

Military government was lifted from Kinmen in 1992. The opening-up of cross-strait relations transformed the island into a tourist destination. This transformation led to electricity and water shortages in Kinmen. With the reduction in the number of troops, military facilities fell into disuse and are now being released for local government use. The aim of this project was to monitor the carbon footprint of a reused military facility during renovation of the facility. The LCBA-Neuma system, a local carbon survey software developed by the Low Carbon Building Alliance (LCBA) and National Cheng Kung University in Taiwan, was used in this project. The system analyzes the carbon footprint of the various phases of the building life cycle (LC) during renovation and carbon compensation strategies were employed to achieve the low carbon target. This project has pioneered the transformation of a disused military facility using this approach. The carbon footprint of energy uses during post-construction operation (CFeu) accounted for the majority of carbon emissions among all stages, at 1,088,632.19 kgCO₂e/60y, while the carbon footprint of the new building materials (CFm) was the second highest, at 214,983.66 kgCO₂e/60y. Installation of a solar cell system of 25.2 kWp on the rooftop as a carbon offset measure compensated for an estimated 66.1% of the total life-cycle carbon emissions. The findings of this study show that the process of reusing old military facilities can achieve the ultimate goal of zero carbon construction and sustainable development.
