Commercial Buildings

Energy: The gold mine for shops and commercial buildings

Buildings for commercial or non-commercial use are the largest energy consumers in all Western countries, with an average of between 30 and 40% of national consumption. For the merchant sector, based on US Energy Information Administration reports and other government sources, the numbers speak for themselves:
• A 20% reduction in energy costs representing the same net benefit as a 5% increase in sales
• 20% of the energy distributed is generally considered as the average energy waste
The evidence is clear: reducing energy losses is an action that is as effective, if not more effective, than the most productive commercial promotion action. For non-food distribution stores, characteristics 73% of energy expenditure is devoted to air conditioning, hot water, exterior and interior lighting. In a food distribution store, refrigeration (positive cold, negative cold, air conditioning) is by far the largest consumer of energy, typically using between 40 and 50% of the store’s total electricity consumption.
In addition, without compromising the comfort of stores for their customers, a simple reduction in heating or air conditioning temperatures by 1°C can reduce energy consumption by up to 8%.
The same goes for hotels/restaurants and office buildings where it is out of the question to reduce the comfort of the premises at the risk of losing customers or tenants or dissatisfying the occupants of the buildings.

The energy challenge in commercial buildings

Who consumes my energy?

Who consumes my energy?


The shops, supermarkets, malls and other commercial sites cannot be satisfied to see his energy bills continuously increase, increase, increase without reacting. It is directly the profitability of the activity that is called into question.
But it can be extremely complex to identify the major consumption items and the possible sources of savings:
• Electricity meters are connected to a beginning of analysis but often very imprecise because they have no real knowledge of the equipment installed and their use and are content to deduce an approximate distribution of consumption and generally 30 to 50% is allocated to “other uses”.
• Water, a major cost item, is also a real unknown because we are too often satisfied with a single overall consumption meter with periodic readings spaced out over time, allowing practically no interpretation
• Situation often similar for possible sources of fossil energy such as gas, fuel oil whose consumption measurements remain global and in time shifts

SILENO e3m is designed with BIG DATA in mind (3V rules: see the “link” techno page: Volume, Velocity, Variety) to collect as much information as possible and as much as possible in real time. Only a massive acquisition of this type of information will allow the fine analysis to identify the sources of immediate savings.

No concessions to the comfort of the customer's visit

No concessions to the comfort of the customer's visit

Points of sale must ensure a level of customer comfort: quality of lighting, comfortable temperature & humidity conditions, efficient and discreet ventilation, air quality, pleasant and non-intrusive sound environment… and many more other settings.
This overall comfort in the experience of the place of sale participates or even is predominant in the duration of the customer’s presence. Or all the statistics show a clear correlation between the amount spent and the duration of the customer’s presence in the store.
In other words, the more pleasant the customer’s visit experience, the higher his bill and the merchant’s profit will be. Similarly, a comfortable office is the guarantee of retaining its tenants.
The very basis of energy efficiency is to meet this need: to offer the same comfort and the same services without any concessions but consuming less (see the energy efficiency page – link).
SILENO e3m has the ability, different from technical management systems such as BMS for example, to be able to correlate source data as different as the technical data of the energy consumed by the point of sale, whatever the energy, with data outdoor weather or customer traffic data.

How to invest in times of budget crisis?

How to invest in times of budget crisis?

A commentary from the academic co-director of CERRE, Professor Nils-Henrik M. von der Fehr, May 2022 (source
“Rising energy prices have put considerable strain on the energy market. The most obvious implication is increased consumer bills, but more basic, power distribution is shaken to its foundations. Contracts have been broken, distributors have gone bankrupt and governments have brought back energy measures to support the market and compensate those who have been harmed.
This unprecedented rise in energy prices was impossible to predict. Consequently, it may seem unfair to criticize possibly being ill-prepared, whether consumers under variable price contracts, energy distributors who had not hedged their exposure to wholesale prices or regulatory authorities who were not prepared. “
However, the crisis is there and will probably be for a long time and companies, in particular in the retail sector, a large consumer of energy and for whom the relative bills weigh very heavily on budgets, must face up.
This is the paradox of the current crisis: retail budgets have not provided for investments linked to energy reduction and energy-related costs are exploding. It’s a double jeopardy.
SILENO e3m offers innovative methods of financing its solutions that allow you to reduce your energy-related costs: economy of use, economy of functionality, scalable localization… All these solutions can be adapted to your case and allow you to withstand this period of crisis.

e3m advantages

Easy data acquisition
Easy data acquisition

SILENO e3m has all the data exchange protocols used in construction and is able to extract the information hidden in your existing systems. No modifications to existing systems are required. The data is already there, it's up to SILENO to collect it.

No new system to install
No new system to install

SILENO e3m is non-intrusive and requires little or no local installation of new hardware or software. Preferably, installed in the cloud, SILENO e3m can however also be installed locally when the conditions impose it under, for example, data security or unstable internet connection.

Cost visibility and financing of your energy efficiency
Cost visibility and financing of your energy efficiency

Based on a simple usage model: annual cost per measurement point or with professional scalable and modular leasing, e3m allows you perfect visibility and forecasting of your operating costs to avoid investments and fixed assets but to integrate our solutions into operating costs.
