4. Goals

5. Providing comfortable and healthy environment for people

6. Reducing the Climate Change Gases emissions , and its impacts

7. Reducing energy cost of a building

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

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.

ENVIRONMENTAL ANALYSIS

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.

32. HONEYBEE FOR GRASSHOPPER
Honeybee connects Grasshopper3D to EnergyPlus, Radiance, Daysim and
OpenStudio for building energy and daylighting simulation . The Honeybee
project intends to make many of the features of these simulation tools available
in a parametric way.
