Non-Commercial Buildings

Energy efficiency at maximum potential

There are many buildings in the non-commercial sector: public and private administration, education, places of worrship, social action. At SILENO, we prefer to take to set aside the health sector, which has certain particularities in terms of energy efficiency. There are several million employees working in offices and it can be estimated that this represents around 25% of the total electricity consumption of the tertiary sector. According to the French agency of ADEME:
• Heating accounts for 50% of energy consumption in the office;
• The lighting of the premises corresponds to 20% of the total energy bill.And as in the other buildings:
• Reducing temperatures by 1°C can reduce energy consumption by up to 8%
• 20% of the energy distributed is the observed average energy waste
But moreover:
• More than 70% of indoor lighting consumption in buildings is done during the day (Source because there are still few systems linked to presence detection or natural light
• The night lighting of buildings represents 15 to 30% of direct losses
• The vacancy rate for business premises has risen sharply in recent years with, for example: from 4.8% to 7.4% in one year in the business district of La Défense (source “La ville unoccupée” by N. Arab & Y. Miot – Presses de l’école nationale des Ponts et Chaussées-France).
With these impressive figures, we can think that the majority of these energy losses could be reduced by respecting internal regulations, discipline for everyone, but it is necessary to have detection tools to allow both:
– Identify consumption and correlate this data with the control of the use of the premises to verify that all consumption corresponds to the use of the place

– To respect the rules of energy efficiency and not to reduce the quality of service, the comfort of use of the premises for its occupants

e3m: Energy Efficiency made easy

Reducing my energy bills: it's possible!

Reducing my energy bills: it's possible!

According to the French Ministry of Ecological Transition, energy waste represents around 30% of building consumption, i.e. a loss of around €6,000 per year lost per 1,000m2 of surface area at the 2022 kWh rate in France… With the increases expected in 2023 in the price of electricity in France, the bill for a building of this size would rise by 30 to 50%. By comparison, in Switzerland, the increase announced for 2023 would double the total.
The implementation of our e3m solution makes it possible to identify waste easily and in a few weeks. With an early implementation of e3m system, it is possible to compensate for increases in energy by targeting the elimination of only 50% of the identified waste.
Thus, the return on e3m investment is extremely fast: from a few months to 4 years at most for installations that are already very efficient today.

Simplify the management of energy bills and customer relations

Simplify the management of energy bills and customer relations

Multiple sites, a continuous and permanent change of tenants and office configurations is already a significant management burden, but in addition, it is necessary to ensure the accuracy of customer consumption readings and provide clear justifications for invoicing.
With the a3m (Asset) and c3m (Contracts) portals, the management of contracts, subscriptions, billing of consumption natively integrated and of course interfaceable with existing accounting and customer applications.
e3m also integrates with existing management applications: accounting management, equipment management, customer management, all IT interfaces are available and easily configurable for your particular case.

Measure energies but not only that

Measure energies but not only that

Perhaps more than other sectors, the field of tertiary building requires the collection of energy data but also a lot of other information on the use of premises in order to adapt energy consumptions to usages. e3m from SILENO goes even further and also integrates building usage and comfort data using wireless sensors, for example in Lora, LoraWan, Sigfox, NB-IOT technology like independent wireless sensors linked to the quality of the atmosphere: measurement of temperature, humidity, air quality (C02, VOC, RADON, etc.), natural light, artificial light, door opening/closing, presence, movement, security of premises, ventilation, environment: outdoor meteorological sensors, solar luminosity, etc.
This resulting ability to acquire information and process massive data (Big Data) makes it possible to study all possible correlations and easily deduce potential energy savings.

No matter where your data resides: manual entry in Excel, supplier or distributor portals, BMS, BacNet/modbus field network… e3m is able to recover, log and analyze it in the simplest way possible.

e3m allows you very easily to correlate all types of data with powerful graphic tools (any type of curve, widgets, smart objects). In a few minutes, you have the ability to discover your installations in a new light.

Integrated SCADA

SILENO's e3m is not just an EMS system, the SCADA supervision functions (synoptics, installation monitoring and control, alarms, etc.) are natively integrated both locally with the e3m-Box (optional) and the local application or hosted e3m.
