Growing interest towards carbon neutrality have led to the proliferation of carbon footprint calculators (both online and software) to aid building professionals in quantifying the carbon impact of buildings. While carbon calculators can ease design-carbon quantifications and expedite design decision-making, the use of such carbon calculators is often tedious, time-consuming, and difficult due to the need for extensive input data, lack of dependable localized carbon data, transparency, scalability, and interoperability.

This research pursues an experimental implementation of an analysis framework in conjunction with an optimization framework for building design. The frameworks tie authoring and analysis tools together under one umbrella. In a prototype, the data flow uses a mix of proprietary and publicised file formats, exchanged through publicly accessible interfaces. An analysis framework brokers between the parametric authoring tool and the analysis tools.

A numerical model is developed to accurately simulate the transient thermal behaviour of rooms with sun-facing windows, with the use of a refined spatial and temporal discretization. For each node, the energy balance equations are developed based on a consideration of radiation, convection, air enthalpy and three-dimensional heat conduction. As buildings are exposed to rapid climatic variations (particularly incident solar radiation), we have added the different environmental conditions at short time-steps.
