Life Science Solutions
Providing solutions and expertise from people dedicated to making laboratory environments that are safe, efficient and operationally consistent.
Laboratory buildings typically have 100% outdoor air requiring considerable energy to condition before being delivered to the rooms. Often energy consumption is 3 to 8 times higher than office buildings. This is driven by requirements for 24/ 7 operation, meeting room air changes for dilution ventilation and safeguarding researchers.
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
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 room temperature, humidity, pressure sensors and ductwork airflow measuring stations combining quality and reliability with the highest energy efficiency.
Fume Cupboard Control
A key component of safety in a research laboratory is the fume cupboard. Selecting and maintaining proper face velocity at the fume cupboard particularly on a manifold exhaust is a challenge. 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.
Integrating multiple indoor environmental quality (IEQ) parameters including TVOC’s, Air Particles and CO2 is used to dynamically adjust room air changes. This significantly increases energy savings while ensuring spaces are clean at all times.
Air Particle Measurement
Integrating air particle counting in clean spaces to dynamically adjust ventilation flow rates to reduce energy costs.
Indoor Environmental Monitoring
Validating room conditions and air particles in critical environments. Store and document temperature, relative humidity, air circulation, pressure and air particles.
Building commissioning provides confirmation that building systems function in compliance with criteria set forth in the Project Documents to satisfy the Owner’s operational needs.
