The context for this article is sustainable and ecological green city and building design; the intent is to advance architecture and ecology integration and multi-species design in architecture through the development of a conceptual framework for and computational approach to the early-stage design of ecological building envelopes, which are enclosures of buildings that make provisions for humans, plants, and animals. This entails two research questions: (1) how to integrate architectural and ecological domain knowledge into a conceptual and methodological framework and (2) how to develop a computational workflow and components for the early-stage design of ecological building envelopes. A mixed-method approach was used to develop an <i>ontology-aided generative computational design process</i> that combines computational ontologies, a voxel model, and rule-based processes that generate design variety. The process was developed to support two dominant design cases in architectural practice: masterplan design and building design. This article outlines the underlying key concepts, the computational workflow, and the developed key computational components and summarily indicates validation approaches during the development process. Finally, thoughts on the technical implementation of the computational workflow and components are indicated and further research questions are outlined.
