Abstract
Keywords
A modular-based Green Design Studio (GDS) platform has been developed in this study for fast and accurate performance analysis for early stage green building design. The GDS platform aims to simplify the design and analysis process by embedding performance parameters into design elements in modules and employing near-real-time model for whole building performance simulation as well as by providing an easy-to-use and intuitive user interface to assist users without extensive knowledge on building physics. The platform consists of building modules as fundamental building blocks, performance predicting models, and a user interface for visualization and interactive design. In the platform, a whole building is composed of modules organized in a hierarchical structure, including spaces, enclosures, service systems, sustainable resource systems and sites. Both physics-based and data-driven models can be used to simulate the building performance and optimize building systems. A simplified physics-based model, the Resistance– Capacitance (RC) model, has been proposed as a generic simulation model for the flows of heat, air, moisture and pollutants, which is significantly faster than conventional simulation tools such as EnergyPlus, and hence more practical for use in real-time design interaction and optimization. A pilot case study is conducted to illustrate the modular-based design approach using a section of an office building. Compared to conventional building performance analysis tools, the GDS platform can provide fast and reliable feedback on performance prediction for early design. The modular approach makes it easier to modify the building design and evaluate the potentials and contributions of various green design features and technologies.

Introduction
1.1 Background Rising global concerns over energy, environmental and climate issues such as air pollution and global warming have drawn increasing attention to high-performance building design. Buildings worldwide account for over 30% of total energy consumption and 30% of global carbon dioxide (CO2) emissions (Bosseboeuf 2015; BERC 2018; IEA 2018a, b; EIA 2019). Indoor environmental quality (IEQ) in buildings also plays a key role in occupant health and comfort as people spend nearly 90% of their time indoors (Klepeis et al. 2001; WHO 2005; Schweizer et al. 2007; E-mail: [email protected]
