Energy efficiency is vital in today's architecture as effective energy can save money and reduce pollution to the global and the environment. As this is my first module that concentrates on in-depth learning of energy, so by completing this project, I have understood the role of energy efficiency in low-energy buildings. Additionally, learning through understanding an existing building brings me a deeper knowledge of the energy-efficient strategies by researching real-life conditions. Moreover, other than doing self-study on these strategies, the support and assistance from lecturers and my groupmate really help and clarify me a lot during the process.
