To significantly reduce costs and to improve levels of building user satisfaction, organisations are looking more at monitoring and managing their environmental performance. Eight Associates can provide a comprehensive package of services for organisations to recognise and trace behaviours, and understand the nature of their environmental impacts. This allows targets to be defined, plans of improvement to be put in place, and potential grants and funding opportunities accessed.
