How to optimize your energy consumption?

As part of the energy transition, the law requires organizations to reduce their energy consumption and to favor the integration of renewable energy. To optimize energy consumption, it is essential to have a good understanding of energy data. With its N'Gage platform, Energisme supports actors in the collection, analysis and exploitation of energy data.

How to calculate the energy consumption of a building?

Before you can optimize your energy consumption, you need to measure it accurately. 

For that, it is not enough to add up the amount of your energy bills. The reality is more complex. A building mobilizes multiple energy vectors (electricity, gas, water, heat, …). 

Most of the time, these different vectors depend on different suppliers and networks. As they are not interconnected, the data you receive from suppliers are not necessarily interoperable. In a logic of optimization, the compartmentalization between actors and networks is an obstacle. 

The N’Gage platform, developed by Energisme, addresses this issue by facilitating the collection, analysis and exploitation of multi-fluid building data from multiple sources:

  • Billing data issued by suppliers
  • Remote reading data from network managers
  • PLCs and BMS (Building Management System)
  • IoT sensors connected to equipment

All these data sources are aggregated in the platform, cross-referenced and analyzed. You thus have not only a tool for real-time monitoring of your energy consumption but also a global building energy analysis system.

How to reduce your energy consumption?

Once you have an accurate view of your energy consumption, you can then implement optimization actions.

How to meet the objectives of improving energy performance?

For many organizations, this is even a regulatory obligation. For example, for the commercial real estate industry, the decree sets targets for improving the energy performance of the building stock by 2030, 2040 and 2050. 

To meet this obligation, the professionals concerned are required to measure their energy consumption and share their data on the centralized platform OPERAT, managed by ADEME.

At the same time, they must implement action plans to reduce energy consumption:

  • Energy renovation of buildings
  • Monitoring of energy performance, detection of energy losses and replacement of energy-intensive equipment
  • Adjustment of energy consumption to the real needs of the occupants

Energisme’s platform facilitates the implementation of a centralized energy management system within a building stock. It allows you to follow your trajectory in relation to your energy consumption reduction objectives. 


How to precisely identify the origin of energy losses?

But, above all, thanks to the granularity of the data and the analysis capabilities of the solution, you can precisely identify the origin of energy losses or adapt consumption to occupants’ uses. This smart building dynamic appears today as a priority lever to optimize energy efficiency.

Green energy: what is it?

In addition to reducing energy consumption, replacing fossil fuels with green energy is another aspect of the energy transition.

Energie verte

Green energy refers to electricity produced in an environmentally friendly way, generating no or low greenhouse gas emissions and waste. It is also a sustainable energy because it relies on renewable and inexhaustible energy sources. Among these renewable energies, we find solar energy, wind energy, hydraulic energy, …

The law of energy transition for a green growth plans to increase the share of renewable energy to 32% of the gross final consumption of energy in 2030.

The intermittence of certain renewable energies

Previously, the intermittency of certain renewable energies complicated their integration into the energy mix. Now, the increasing networking between energy consumers, suppliers and grid operators within smart grids offers new possibilities.

Our data collection platform

The collection, analysis and availability of energy data via the Energisme platform promotes synergies between players. This improved predictability of consumption facilitates the adjustment of consumption and the increase of the share of renewable energy in the mix.

Optimizing energy consumption

Environmental challenges

Environmental challenges

what are the challenges?

Optimizing energy consumption is primarily a response to environmental issues. The public authorities have made commitments to limit greenhouse gas emissions and global warming. The integration of renewable energies is also written into law.

The energy transition is now an obligation to which all organizations are subject. The laws sets quantified objectives and requires actors not only to monitor their trajectory but also to implement action plans.

A profitability driver

what are the challenges?

Reducing energy consumption in a building stock is also a question of profitability. As some aging buildings generate high energy costs and high maintenance and upkeep costs, energy retrofitting is a serious option.

However, in order to undertake actions to optimize energy consumption, real estate professionals must be able to rely on complete and reliable data. The evolution towards smart building allows rationalization of the approach.

The N’Gage platform, developed by Energisme, offers an overview of building data. It permits a move from scheduled maintenance to predictive maintenance, taking into account consumption, usage and the state of wear and tear of equipment. 

In addition, users can use the solution to make predictive estimates of their consumption and costs according to different optimization scenarios. Since the decision making is informed by the data, their risk taking is reduced.
