The document discusses computational environmental design goals of providing comfort while reducing environmental impacts. It describes analyzing site climate data using Ladybug tools to understand temperature, humidity, wind, solar radiation and their effects. The environmental design process begins with research and analysis before brainstorming, testing and strategizing solutions using energy modeling tools like Ladybug and Honeybee for Grasshopper. Building performance is then simulated to evaluate techniques like a breathing facade. In tests, passive design reduced internal temperatures to the comfort zone in summer and winter.

- 8. BUILDINGS ARE DESIGNED FOR PEOPLE, and those people are trying to accomplish a task – whether it’s raising a family, running an office, or manufacturing a product. THE BUILDING NEEDS TO KEEP PEOPLE comfortable, efficient, healthy, and safe as they set about their task. ENVIRONMENTAL DESIGN SEEKS TO create buildings that keep people comfortable while minimizing negative environmental impacts

- 24. ENVIRONMENTAL SITE ANALYSIS Using LADYBUG FOR GRASSHOPPER
- 25. LADYBUG FOR GRASSHOPPER Ladybug is a free and open source environmental plugin for Grasshopper to help designers create an environmentally-conscious architectural design. Ladybug imports standard EnergyPlus Weather files ( .EPW) in Grasshopper and provides a variety of 2D and 3D designer-friendly interactive graphics to support the decision-making process during the initial stages of design.

- 28. The initial step in the design process should be the weather data analysis; a thorough understanding of the weather data will, more likely, lead designers to high-performance design decisions. The tool also provides further support for designers to test their initial design options for implications from radiation and sunlight-hours analyses results. with Grasshopper allows for an almost instantaneous feedback on design modifications, and as it runs within the design environment, the information and analysis is interactive.
