Projects
The Estates and Buildings Energy team plan and implement an array of energy saving projects throughout the University estate. These projects have variable pay backs and all save carbon emissions.
The posters describe some of the energy saving measures installed in several University buildings:
Biological and Biomedical Sciences Building
Chemistry 4 - Fume Cupboard Optimisation
The tables below highlight some of the projects which have been carried out or in progress along with their associated carbon savings.
