Trade and Services

All the service sectors are a major focus of the Mindful philosophy. These buildings are continuously used and highly exposed to the public, and therefore they should serve as a prime example. In a society increasingly in need of environmental awareness, control of service buildings is undoubtedly a cornerstone in the evolution of this mind-set.

The adoption of sustainable behaviour is increasingly unrelenting in working towards reducing energy resources consumption, and consequently reduces operating costs and increases competitiveness. A more efficient use of energy allows at the same time to reduce the environmental impact and carbon emissions into the atmosphere, with all the benefits it can bring in terms of environment and external communication into your own business.

Through specialized teams, we work with our clients in the entire process of energy efficiency, providing a complete range of products and services:

  • Energy certification
  • Diagnosis and energy audit
  • Smart solutions for monitoring energy consumptions
  • Platform for managing energy consumption
  • Smart solutions for facilities management

Energy Professionals

We identified the interest amongst auditors and energy managers in companies for an integrated solution that supports the dematerialization of the whole process of managing energy efficiency with a central repository to store all the data produced, so that auditors and companies can easily access.

For energy professionals, the Mindful concept consists of using an ecoefficient tool that supports in an integrated system the entire array of energy management and audit processes of industrial & service businesses, and also in common homes. This solution is available in the Saas model (Software as a Service), and it will allow for fast noticeable results, efficiently aiding the energy manager/auditor in their daily tasks of energy efficiency analysis and the future impact of their improvement suggestions. This way the auditor will be able to ground their decisions related to improvement actions, reduce environmental impact and lower the global energy footprint of their facility.With this solution, it is possible to monitor the whole process of energy audit and subsequent control of the impact of the measures implemented. We offer the following product/service to increase the competitiveness of your business:

  • Applications and tools for process optimization in the field of energy and environment.
