Eight Associates tools – free to download and use



Sustainability decisions are best taken as early as possible in a project. To help ensure you are aware of and equipped to make some of these decisions we have developed a range of tools in some of the areas in which we work. Please feel free to download any of the Eight Associates tools below, and forward to any colleagues or contacts whom may find them useful. If you have any questions, our consultants are happy to informally discuss your project.


♦ Eight Associates Early Design Stage Daylight Predictor Tool – This tool is designed to enable the user to estimate the average daylight factor (ADF), the sky view area and the maximum room depth according to the BRE guidelines at the very early design stage.
