Sustainable Laboratory Design
Laboratory buildings typically have 100% outdoor air requiring considerable energy to condition on hot days before being delivered to the rooms. Often energy consumption is 3 to 8 times higher than office buildings. This is driven by requirements to safeguard researchers with 24/ 7 operation and room air changes for dilution ventilation.
Room Environmental Control
With any building automation approach for laboratories, the ultimate objectives are:
- Researcher safety – local display and alarming of critical environmental parameters
- Room pressurisation – maintain correct airflow direction and pressure
- Ventilation – provide proper air changes for dilution control
- Comfort – provide proper temperature and relative humidity control
Air Conditioning and Ventilation Control
Venturi air valves that adjust and compensate for fluctuations of duct pressure by using a mechanical pressure-independent cone and spring assembly that moves in and out of the venturi orifice, increasing and decreasing the airflow in a very predictable manner.
Factory calibrated sensors for temperature, relative humidity and pressure combine quality and reliability.
Manifold Fume Cupboard Exhaust Control
A key component in a research laboratory is the fume cupboard. Selecting and maintaining proper face velocity at the fume cupboard particularly on a manifold laboratory exhaust can be a challenge for most control systems. The consequences of incorrect face velocity can lead to unsafe conditions with loss of containment when face velocity is too low and energy waste when face velocity is too high.
Demand Control Ventilation
Multiplexing sensing technology can significantly reduce on-going calibration costs over the life of the system. Laboratories air quality is clean and safe while ventilation requirements are optimised for energy efficiency.
