Delivering the continued promise of an Active house, needs rigour and continuous data collection. Leapcraft enabled this via AmbiNode - its indoor environment intelligence instrument with sensors and data processing software that can cope with real time analytics and streaming data. This opens up the possibility to actually look for patterns, analyse historic data and even deliver insights for both planning and remedial measures if required. The deluge of the so called Internet of Things (IoT) is creating unforeseen possibilities in using data to empower the Active house principles with new knowledge.

Leapcraft was invited by Velux to bring in their expertise in deploying sensors to measure and analyse indoor & outdoor climate data at the Green Solution House, a hotel and Conference Center, a zero-impact building built to meet or perform beyond multiple eco-friendly building codes.  Leapcraft’s deployment covered the spaces like a blanket, harvesting data continuously from over 10 locations in the GSH. They measured air quality, temperature-humidity and noise indoors along with environmental parameters outside since Sept 2017 over fall and winter observing the changes in the space. The sensors took thousands of measurements, every day and flashed them to Leapcraft’s lab back in Copenhagen.

Vinay Venkatraman, CEO Leapcraft says, “Our ambition is to enhance the well-being by empowering people with data and quantifying the built environment in real-time”

Leapcraft’s Lab continuously monitors the data on the dashboard custom built for GSH to look for patterns. These patterns have to be vetted against the Active House guidelines and the EN15251:2007 code at all times to look for anomalies and unprecedented events. During the period of approximately 120 days, an average of 15,700 events per device was received in total. That approximates to a total of 1,050 events per day for all boxes. Individually, that is an average of 130 events per day, per device, deployed during the testing period. The system actually measures an increase magnitude, the state changing process might not be seen. Instead, the result of a process are seen in the data. It is of interest to also see the process of change in an environment in addition to understanding the result of such a change.

Leapcraft deploys a family of sensors and continuously harvests data from them to see, if the buildings perform to the standards, they have been coded for. And all this data mining and insight delivers fascinating ways to see the space quantified.  For GSH, this data is valid proof of the indoor life quality it promises to offer. For the authors of the Active House Principles, this is a key feedback in the loop that keeps the certification valid and relevant and for the collaborators of the built space this longitudinal data goes on to see the performance of their products across seasons and time.
