Window automation for green building

AUTOMATION FOR WINDOWS
By the Integration in Building Management Systems (BMS) the window automation allows: ENERGY SAVING automatic switch-off or reduced use of Air conditioning, heating, lights. COMFORT in the building Easy control of window automation through computer or other devices, Quiet operation, Wellbeing that becomes health, then productivity at job place or school… … granting at the same time SAFETY by smoke ventilation in case of emergency.
INTRODUCTION
Total communication between the natural ventilation system and mechanical/air conditioning system to optimize energy saving and assure thermal comfort and wellbeing, becoming health and productivity. At the same time the building’s safety is assured by smoke ventilation in emergencies.
ENERGY SAVING (Natural Ventilation)
Besides capital cost savings worth 15% as compared to air conditioning, naturally ventilated buildings also substantially save on energy due to lower costs for operating the natural ventilation solution (70 – 90% less), in addition to the qualitative, psychological effects on the building’s occupants.
With the mixed ventilation mode, integration and total communication is essential between the ventilation system and mechanical/air conditioning system, in order to reduce the power consumed by fans which could represent up to 25% of total power consumed by the building.
COMFORT (Natural Ventilation)
Latest surveys report that 90% of people are more satisfied with their indoor environment in
naturally ventilated and mixed mode buildings than in buildings with mechanical ventilation and
air conditioning; this preference is mainly due to the fact that occupants have easy access, can
regulate their indoor environment and are not entirely cut off from the outside environment.
A higher ventilation rate implies curbing the concentration of CO2 which can negatively affect people going about their daily tasks, and, in general, reducing cases of illness: 25% to 67% less sick building syndrome symptoms, to the advantage of productivity by 3-18%.
SAFETY ( Smoke & Heat Extraction)
Dedicated Control Panels and actuators, tested in fire conditions, operate windows,
skylights and louvres to extract smoke.
Smoke is the principal cause of death in a building on fire
Emergency exits, escape routes must be free of smoke
Firemen are able to enter, save lives and extinguish the fire
Integrating window automation with BMS
new generation of compact and addressable actuators with integrated programmable circuit board, providing two-way communication with computer system. All actuator functions are totally programmable and the actuators provide 100% real-time feedback on their status. Integrating window automation with the BMS Building Management System will enable interaction with other systems in building (HVAC, lighting…) granting considerable energy saving, improving comfort and wellbeing, becoming health and productivity. At the same time the building’s safety is assured by smoke ventilation in emergencies.
The BMSline actuators are:
> Compatible with all existing building management systems.
> Continual, totally controlled window with real-time feedback. Not just an ON/OFF operation (open/close).
> Addressable actuators in order to control the environment of each room in a building.
> No need for external modules/control panels: the actuator has built-in intelligence.
> Window controlled locally by a standard wall switch, even with a centralized Building Management System.
> Smoke Ventilation Control Panels with back-up batteries can be directly and safely connected.
