The Talk:

This talk is part of the ‘Building Accessibility’ series. The one hour talk discusses the need to provide a luminance contrast between architectural features in premises.

The presentation also provides an overview of the free Luminance Contrast Assessment Tool (LCAT) developed by Access Central (part of the Egress Group). The LCAT is available from

Suitable for anyone responsible for specifying architectural products, certifying designs or checking compliance.

The Presenter:

Who should attend?

This talk is suitable for people of all backgrounds and professions working in the construction and property management. It is designed as an entry-level introduction to the concept of luminance contrast and how to comply with the minimum prescriptive requirements of the Building Code and the Premises Standards under the DDA. Additionally, best-practice concepts will be presented. The use of the free Luminance Contrast Assessment Tool will also be demonstrated.
