The sustainability team of the University were under pressure to reach carbon dioxide reduction targets. They were aware that their laboratory buildings were the largest users of energy and in particular the synthetic chemistry building and its ventilation system. The building contains a large amount of fume cupboards, so safety was a prime concern during the project for both the University and EECO2.The brief for the EECO2 team was to address carbon dioxide reduction within the building and provide solutions for the sustainability team to help reach their targets, whilst working very closely with the University Estates Team and the users of the building, as to not disrupt the ongoing work within the building.
Firstly, the team assessed the safety requirements of the building during a fume cupboard survey. They then performed a HVAC survey to assess opportunities for improvements, again evaluating safety requirements of the building. The survey uncovered a satisfactory HVAC design, however there had been modifications made to the design and components that had failed, resulting in lower efficiency levels than the original design is able to deliver. Using the survey results, the EECO2 team produced safety and energy efficiency suggestions and created an implementation plan. The University’s sustainability team then hired EECO2 to implement the plan. There were issues along the way, which the team overcame, for example, there were concealed holes in the duct work, causing pressurisation issues. The team found and repaired the hidden cavities in addition to the scheduled repairs.
The repairs had to be organised with the University in mind. The EECO2 team had to be very flexible, often working out of hours, ensuring the fume cupboards were free for use when required, reducing the impact on the building users as much as possible.
EECO2 performed extensive testing to develop a revised exhausted fan control strategy, to ensure safe velocities were maintained in the air duct
Repairs, modification and recommissioning of the HVAC system, including the controls and the components
EECO2 did such a good job for the sustainability team, that they have been asked to assess a number of additional buildings on the University campus too.
