The NVLogiQ™ Room Controller has been designed to offer an effective, efficient and user friendly solution for adaptive natural ventilation applications that is easily integrated into a new or refurbished building.
The NVLogiQ™ Room Controller can be used as a standalone system or networked for individual room control with global common signals such as wind, rain and security closing.
The NVLogiQ™ Room Controller is supplied with a pre-programmed natural ventilation control algorithm developed in partnership with Loughborough University’s Building Energy Research Group.
The strategy was formulated by modelling hundreds of comparable scenarios in both education and commercial buildings in conjunction with industry recognised methods and data collected from natural ventilation projects installed over several years Requirements for regulations such as BB101 (internal environment for schools) and CIBSE Guides A have heavily influenced the design of the algorithms.
Dynamic Thermal Simulation models (DTS) and Computational Fluid Dynamics (CFD) have been used to analyse the effectiveness and efficiency of the algorithm.
The system controls room COÇ levels to a variable profile, ensuring that Indoor Air Quality (IAQ) is optimised. The temperature control strategy increases the ventilation rate before internal temperature escalates and becomes uncontrollable. There are multiple temperature control strategies based on external temperature and occupancy, which provides relevant temperature control during the year.
A night purge strategy cools the building for a fresh start and can provide prolonged daytime cooling in buildings with sufficient thermal mass. All settings are adjustable from standard or after the initial ‘learning’ period of occupancy.
Data logging is essential for pre or post occupancy performance analysis. It is capable of recording 3 months of sensor readings and operation signals and is downloadable using a dongle.
