ENN553: 2019 Week 5 Case Study - Energy Optimized Building in Brisbane

This case study examines the design of a Net-Zero Energy (NZE) building, focusing on sustainable systems and energy optimization within the context of Brisbane's climate. The analysis covers various aspects including the building envelope (roof, walls, windows), ventilation strategies, building services (HVAC, lighting, water heating), and renewable energy integration (solar and wind). Detailed recommendations are provided for selecting efficient materials, such as specific window types with detailed specifications and justification for their use, and the integration of renewable energy sources. The study evaluates the impact of design choices on energy efficiency, greenhouse gas emissions, and electricity supply and demand, comparing the proposed strategy with 'as designed' and 'business as usual' approaches. The importance of BIM modeling and post-occupancy evaluation is also highlighted. The assignment aims to provide a comprehensive plan for achieving NZE goals through efficient systems, suitable materials, and on-site renewable energy sources, while also emphasizing the need for detailed data and photographic evidence to support design decisions, especially in relation to the specific climatic conditions of Brisbane.
