Laboratories are high-energy users, consuming up to 10 times more energy per meter squared than commercial office buildings, therefore potential savings are high. Fume cupboards, High extract rates, Poor ventilation design, Density of equipment in laboratories and Poor energy management. With high extract rates associated with the fume cupboards it is important to ensure that the ventilation systems are correctly integrated together to guarantee maximum energy saving potential. The makeup air for laboratory fume cupboards and extract systems are often poorly controlled resulting in excessive ventilation. Changing from bypass fume cupboards with constant volume makeup systems to variable volume systems provide enormous opportunities for savings. Balanced demand based ventilation systems avoid discomfort in adjacent offices and ancillary areas with natural ventilation. Fume cupboards should also be examined to determine the extract rate required to meet health and safety regulations rather than unnecessarily running them at full speed.
An energy survey was carried out in this Richview building and recommendations were identified. A full re-commissioning of the heating installation was recommended to identify any excessive energy cost/consumption within the facility and to help in resolving ongoing complaints about the thermal comfort in the laboratory areas .
The initial survey revealed the over-complex nature of the heating installation, poor implementation of controls to both the heating and the ventilation installation. The ventilation design which was intended to have demand based controls, to utilise the potential for reduced ventilation was only partially implemented in the original construction.
The initial service involved the provision, co-ordination and management of commissioning engineers to re-commission the installation to operate under a new low energy design regime.
Green Energy Solutions have carried out energy saving measures in EPA laboratories Monaghan. GES' role in this project included an energy survey and implementation of controls and commissioning improvements to the Heating, Ventilation and Air conditioning (HVAC) installations, to resolve excessive energy cost/consumption within the facility. Many staff too had been complaining about an uncomfortable working environment. Regulating temperatures in the laboratory area was a major issue and was leading to less efficient workers.
GES carried out works in Teagasc Dairyboard Biology and Chemistry Laboratories in 2013. The building in Moorepark, Co. Cork required a Mechanical Upgrade including a heating and AC refurbishment, a centralised Freezer / Cryogenic storage facilities and many much more. At a later stage, the ventilation and AC system laboratories were also upgraded. Up to this time, chilled beams and low velocity ventilation schemes in the existing laboratories where air movement and test sample contamination had been causing problems. Mixed mode ventilation for the cryogenic/ freezer storage were then introduced to reduce risk to valuable research samples. As this research was an important function to Teagasc, it was imperative that these changes had been made.
