Offices solution: Lighting + shutter + HVAC control for small & mid size office buildings

Value proposition

Main drivers

• Energy efficiency: Reduce energy bills; get credits for environment labels (LEED®...); achieve a better energy rating
• Flexibility : Easily change fit-outs for a new tenant during vacancy period; easily modify internal arrangement
• Employee productivity: Create a comfortable and safe atmosphere with individual local control

Solution in brief

• The solution is suitable for small and mid-size offices (typically <2500m²) buildings.
• Typical HVAC technologies: hot water, central heating, and split system for air conditioning or variable refrigerent fluid.
• The solution is engineered in the electrical package and installed by electrical contractors.
• The solution includes control of lighting, shutters, and HVAC in individual offices, meeting rooms, open space, corridors, and halls.
• Main control features for energy efficiency: automate lighting to people presence and daylight levels; control heating based off of temperature variation, people presence, and opened windows; shutter control
• Possible connection to any Building Management System for an overall time control, for monitoring real time operation of lighting, HVAC equipment in the whole building
• Well-designed and well-operated HVAC and lighting control allows for up to  30 - 50% reduction of energy consumption.
• Using this solution helps to achieve the best possible energy rating, for example in Europe -- an "A" rating for the building control according to the EN 15232 standard
• 20% t ime savings on average, when adding new functionalities or changing the office internal arrangement compared to using wired technologies
• No computer, no software is required to operate the building.
• Single engineering and contracting company for power and control: electrical engineering; electrical contactor takes the full responsibility of the installation, light level and temperature variation; time control
