Portfolio Company: Smart Metering by Silentsoft SA saves 10% energy

The railway construction cooperative Dietikon wanted to know the true results folowing the renovation of its buildings. A retro-fit smart-metering-system installed by the Swiss company Silentsoft SA not only demonstrated it – it also made supplementary energy savings. Silentsoft SA is a portfolio company of New Value AG is coached by paprico for several years.

Before the renovation, the buildings had a «D» classification and needed more than 65 kWh per m² per year. Following the renovation of the façade and heating system it improved one energy class to a «C». Energy consumption was reduced by 25%. Silentsoft installed a smart meter system. The devices capture consumption indexes every 5 minutes. For the gas burner, inputs and outputs, burner time usage, energy consumptions and inside and outside temperatures are measured. For the solar accumulator the volt-ampere in KWH and the temperature are measure. The data is sent once a day on the internet portal and is presented in a clear and understandable manner. The Silentsoft portal showed that technical improvements could be made in the heating systems: The cooperative could make improvements on the inputs and outputs of the distribution system, the time of burner usage, and the number of times the burner would turn on. These relatively simple measures resulted in extra savings of 12% in energy consumption.

Founded in 2000 in the campus of the EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland, Silentsoft developed a state of the art telemetry solution which enables automated real-time communication between machines and the provision of critical business information to customers. Silentsoft is a European leader in tememetry based solutions for building energy management and bulk product invetory monitoring. Silentsoft provides an end-to-end solution, including hardware, field services, data processing and information delivery. Once in operation, the web based portal “SevenDays” provides real-time visibility on inventory levels, energy consumption and CO2 emissions from a single tank or meter, to a single building, to an entire building park.
