Productivity Gains underpin strengthening interest in SenseAgent System

A high profile qualitative research paper from Harvard University School of Public Health has highlighted the cognitive effect of poor air quality and the importance of ‘Building Wellness’.

Previous months have seen a significant uplift in customer awareness of Levaux generally and with it a widespread acceptance of and consequential refocus towards building ‘wellness’ delivered by Levaux, alongside its lighting control and energy management solutions.

Backing the overall findings of the Harvard study, Schneider Electric have indicated they believe there may be as much as 25% improvement in productivity attributable to superior air quality. The implication for building owners and developers is very positive. Levaux is seeking to understand more and to validate empirical evidence of wellness and productivity. Initial findings are discussed below:

Deployments are delivering significant learnings

SenseAgent LP4-203 Hilbert sensors are equipped to monitor air quality through a range of metrics. Some interesting and significant discoveries have been made across our deployment sites. The SenseAgent cloud platform has enabled the following quantitative environmental comparisons across different geographical locations and regions.

This deployment below shows normal range of CO2 during business hours is well under the World Health Organisations 800ppm threshold.

Normal Co2 levels over 24 hour period in office space.

An office site where the climate is not as well ventilated in order to save energy, as shown below, sacrifices employee productivity as CO2 readings exceed safe guidelines.

Co2 levels which exceed WHO guidelines.

An interesting observation seen here at 3pm in this graph is how quickly CO2 can climb with the occupancy detection lag for climate systems to counter the effect of numerous people in a meeting room. This suggests intermittent automated ventilation to counter the CO2 spikes, which would improve productivity without reducing energy efficiency.

Co2 changes as HVAC configuration changes throughout the day.

Technology & Engineering

Levaux has been working closely with our technology partner Wirepas to accomplish new low latency mesh capability at scale for our SenseAgent solution on the 2.4GHz spectrum in a commercial environment. This is vastly higher bandwidth than IEEE 802.15.4 or flood broadcast BLE mesh network.

Our mesh network now has accomplished 1 second sampling of 10 different metrics/sensor with simultaneously 5-second live cloud tracking and bidirectional connections for endpoints. Tracking resolution is now approaching 50cm resolution. Our fingerprinting and trilateration algorithms are rapidly making gains in refining positional resolution. This is an important analytical tool for productivity and space utilisation with implications for security and energy management of lighting and climate.

Blancpain GT Asia Series

Levaux was proud to be invited by Craft Bamboo Racing from Hong Kong to participate in the opening round of the Blancpain GT Asia Series at the Sepang International Circuit, Kuala Lumpur. Craft Bamboo is the factory Porsche team in the Asian series and runs two 991 GT3-R race cars. We look forward to sharing in their success as the series moves from the racing in Malaysia to Thailand, Japan and China.

SenseAgent was proudly featured on the #911 car raced by Shae Davies (AU) and Sandy Stuvik (TH). It was impressive to observe an incredibly well managed racing organisation whilst networking with commercial property professional’s trackside. Asia represents a strategic focus for Levaux as we complete our first major deployment in Singapore.
