Project summary

Are you living in a hot house? Is your home as comfortable as it could be?

The answers to these questions vary based on climate and geography, making it difficult to find the right advice. Home builders and renovators are confronted by many choices and need short, snappy advice to make sustainable choices.

Using internet of things devices we have captured the temperature inside two similar homes, differing in roof colour. The temperature and complimentary messages are streamed to a digital billboard in real-time.

The challenge

Builders are overwhelmed with decisions and have limited time and attention to incorporate sustainability into their homes. This is complicated by a lack of information at the point of purchase. Builders and renovators need to recognise that sustainability should be built into their homes and independently seek information. Available information falls broadly into two categories either from commercial entities (with a vested interest) or published at a national or international scale (with unknown local relevance).

To address these challenges it is necessary to undertake impartial, local research and present it to home builders. To encourage builders who would not otherwise consider sustainability when building, the information should be interesting and engaging as well as factual.


Our digital billboard is putting sustainability front and centre for builders and renovators. Attention-grabbing advice, in high traffic areas, guides home builders to make choices that will result in a comfortable and energy efficient home. Locally relevant information is distilled and displayed as eye-catching graphics. Drone footage showing the impact of roof colour, data-informed graphics updated in real time (see picture) and tips rotate across the digital billboard. This project delivers essential facts about sustainable building, without getting bogged down in details or complex ideas. The information is available to a passive audience, so builders do not have to go out of their way to seek information or look at multiple publications.

To encourage professionals in the field of energy efficiency, planning and building more detailed information is available on the website The website displays recent data visualised at a glance and available for download for personal use.


The benefits of building sustainable homes can reach individuals and communities. For the home occupant, a sustainable home can reduce electricity bills and improve comfort. One a neighbourhood-wide scale building sustainable homes can reduce urban heat-island effects.

This project provides proof of concept for linking internet of things devices to smart signs, which could be replicated.


The digital billboard has been deployed in high traffic areas and in at high exposure community events.

The data generated by the project has been published to and a dedicated webpage built to display the data and step builders quickly and simply through green building principles. The full dataset is available for practitioners to download from the website.
