There are several sustainability services we can provide for our clients including:

Embodied Carbon. We have invested in developing an exciting new embodied carbon assessment tool. Using the ECAT, Walsh have developed a system to internally monitor the sustainability of our projects via, in part, Embodied Carbon Assessments. Walsh can provide reports and graphics on the sustainable performance of our designs to our clients, as our way of helping raising awareness and inform on environmental impacts. The tool is built on the foundations of research, conducted at several leading universities, and we’re working with UK-GBC & industry experts on creating guidelines for businesses to use. The tool is currently being audited by a leading UK university.

Specialist BREEAM advice. There are numerous areas where Walsh has the capability to influence BREEAM credits gained throughout the design process, however use of our whole life carbon assessments opens up additional possibilities to gain innovation credits. We estimate that on a typical project we could add approximately 5 percentage points to the final score, with the potential for almost double.

Sustainable Urban Drainage. Walsh is proud of it’s expertise in Sustainable Urban Drainage Systems (SUDS), and even helped pioneer one of the earliest examples of a modern SUDS systems, which was later used by CIRIA as an industry case study.
