The systems approach to energy efficiency
Orygeen stands out for its systemic approach to energy efficiency. We work on all of the company’s activities: on tertiary and R&D buildings, on industrial sites, where the process is at the heart of the potential for reducing consumption, and on the consumption of the supply chain.
With its experience and the effectiveness of its recommendations, Orygeen guarantees the quality of the installations carried out and conceives the reduction of energy consumption in a logic of continuous improvement.
Optimising the energy consumed by industrial processes
Le process et les utilités concentrent l’enjeu énergétique d’un site de production. Alors comment appréhende-t-on son optimisation ?
REDESIGNING NEEDS AND OPTIMISING OPERATIONS
If you want to consume less energy while producing a product with the same or higher quality, safety and productivity, you have to really involve the teams in the company, for example via methods from Lean Manufacturing and Kaizen.
In close cooperation with its customers, Orygeen will :
Rethinking process steps, processing methods and associated technologies
Reviewing production and maintenance procedures
Optimising consumption during periods of non-production
RECOVERY OF WASTE HEAT
As a quantity of energy available when it is neither recovered nor used, waste heat is the largest source of energy still available in industry. Simple solutions allow, for example, to recover heat from compressors or boilers with very good return on investment times. In order to identify the best heat and cold recovery options at the heart of the process, thermal integration uses PinCH methods or process energy and exergy analyses.
Within a heat recovery mission, Orgyeen could:
Model thermal fluctuation
Choose the most profitable options
Design and adapt the exchange system
Implementing and measuring results
Propose and organise a portage via a third party financing
OPTIMISATION OF TECHNICAL PRODUCTION EQUIPMENT
The transformation of a product on an industrial site (e.g. in an oven, a mill, an extruder, a fryer, etc.) involves a number of possible optimisations of the technical equipment of the process as well as the production and distribution of utilities (heat, cold, compressed air, water, vacuum). A global approach to the entire production chain makes it possible to identify real levers for improvement by regulating equipment, optimising it or replacing it.
To optimise the technical production equipment, Orygeen takes care of :
Distribute and analyse consumption and equipment used
Detect and account for the possible improvements, including subsidies and CEE
Arbitrate between optimisation and replacement
Design the new solution
Install and commission the designed solution
Organising its portage and third-party financing
MEASURING AND MONITORING PERFORMANCE
In order to manage energy efficiency, set objectives and monitor their achievement, involve teams, react to deviations and demonstrate results, it is necessary to measure.
The transformation of energy performance is a continuous improvement process that can eventually be supported by the ISO 50001 standard.
For Orygeen, the implementation of energy efficiency management goes through the following steps:
Establish the metering and energy management strategy
Defining the follow-up indicators according to influencing factors
Choosing the adapted hardware and software digital solutions
Create pertinent dashboard
Define alarm levels and associated necessary actions
Implementing management rituals
Energy efficiency in buildings
Whether for production sites, logistics sites, office buildings or commercial areas, Orygeen works on the 3 main energy efficiency levers of a building :
- air conditioning, ventilation and heating,
For areas subject to the tertiary sector decree, Orygeen’s teams identify precisely the square meters concerned, define the reference consumption and design the action plan to achieve the 2030 and 2040 objectives.
We also assist companies in defining and implementing solutions for measuring and monitoring the energy consumption of buildings, particularly in relation to the new regulations.
To really improve the energy efficiency of a building under construction or renovation, Orygeen proposes to :
Define the real need
Propose the best technological choices
Define the appropriate steering systems
Installing the right solutions
Optimising maintenance and operating procedures
