Green Roof Design Considerations
GBCI: 0910000152With a focus on hybrid green roof systems, this course provides an overview of green roofs, including system options and design and specification considerations such as plant selection, irrigation, mitigation of wind pressure and fire risk, sloped applications, and warranty options.

As energy demands rise and smog and other pollution impacts our cities, many cities and states are encouraging “green” building methods, including green roof systems. Cities also encourage green roofs to reduce storm water surges, to protect the ground water, lakes, and streams, and to conserve energy.
This course was developed to provide the best practices for designing green roofs and includes design-related issues which may not be obvious, but can have a large impact on the success of your project. Design considerations that will be reviewed include: plant selection, plant design, climate, and irrigation methods.
As well, engineering considerations are presented that help to optimize energy efficiency and to minimize the threats to the security of green roofs, such as high winds and fire.
An evaluation of the various green roof systems is included, along with hybrid systems that are designed to package all of the advantages of the different green roof systems and to leave out the drawbacks.
- Define and compare the various green roof system options in terms of performance, cost, maintenance, etc.
- State the recommended types of plants, plant designs, and irrigation methods that help reduce energy consumption and allow the green roof to be fully optimized.
- Discuss how to properly design and engineer the green roof so that it retains its integrity during high winds and mitigates fire risks.
- Review the design and specification considerations to avoid problem areas and facilitate a successful green roof installation.
