Excel Tools

With two long-time software applications developers in the team SustainSuccess are extremely conscious of the importance of ease of use in any software tool. The excel tools we have developed have been created to meet specialist requirements of sustainability, energy and resource efficiency programs which are not catered for by mainstream business applications. Here are a few of the SustainSuccess tools that are in use in energy and resource efficiency programs globally.

If you have a requirement for a software tool we will be happy to advise on the availability of commercial tools or give you a quotation for developing a solution for you. We currently program largely in Excel and other Office Applications. If you are interested in one of the applications shown below please click on the title for more details.
