Our

SDA Tools App

designed for NDIS Specialist Disability Accommodation (SDA) assessments has won the

2021 Australian Access Awards

Presented by Centre for Accessibility for the

Educational App of the Year !

 The Awards are presented by the Centre For Accessibility Australia which is an industry and not-for-profit collaboration working to promote digital access. 

Vista Access Architects have developed the SDA Tools App which are a series of 3 calculators designed to assist and educate Designers,Certifiers and Developers with 3 key areas required for compliance with the NDIS (National DIsability Insurance Scheme) SDA (Specialist DIsability Accomodation) Design Standards.

1. NDIS SDA Density Calculator:

This calculator is to determine the number of participants permitted on a single parcel of land based on our interpretation of the NDIS SDA Rules 2020

2. Luminance Contrast Calculator:

This calculator is to select colours to satisfy the minimum 30% luminance contrast requirements as noted in the NDIS SDA Design Standards for Improved Liveability Design category dwellings.

3. Slope / Gradient Calculator:

This calculator is to assist designers to convert measurements of slope and gradients between a percentage, degrees or as a ratio.

'LRV Contrast' App developed by Vista Access Architects and BEZAPPS for calculating LRV (Luminance Reflectance Value) Contrast has just been judged as a finalist in the 2019 Australian Access Awards for the Educational App of the year category.

The awards are an initiative of Centre for Accessibility The role of the Centre for Accessibility is to empower the accessibility movement and encourage organisations to implement digital access when designing online resources. In 2019 they announced the inaugural Australian Access Awards, celebrating organisations that have successfully implemented accessibility in their digital campaigns or resources.

The LRV / Luminance Contrast Calculator is an easy to use educational tool, available in an online version on our website at https://www.accessarchitects.com.au/calculators and also available to download for free at the AppStore link for iphones / Apple devices and GooglePlay link for Android devices.

The majority of people who are blind or vision impaired have some vision. The purpose of the LRV Contrast App is to assist with selection of colours for building elements to enhance access to information and navigation of the built environment for people with vision impairment.

This is based on not the colour contrast but the luminance contrast which is the light reflected from one surface compared to the light reflected from another surface.

The LRV Contrast App can calculate the luminance contrast based on the LRV of a colour which is easily available from all colour/paint suppliers or on paint samples / fandecks. While the surface or paint finish also plays a role in the Luminance Contrast, it is anticipated that this App will assist with colour selections, at the design stage itself and assist as an educational tool for designers and builders.

The App has been designed to check if compliance could be met with minimum contrast requirements of building elements such as doorways, stairway nosing, toilet seats, signage and different types of Tactile Ground Surface Indicators as mandated under the NCC (Australian National Consruction Code). The formula is based on the Bowman-Sapolinski Equation as required by the NCC (National Construction Code) and Australian Standards AS1428.

It also has a feature to check for compliance with American DDA (Americans with Disabilities Act) LRV requirements.
