Eneron - the solution and its development

Development of Eneron, its concept and procedures, has required cooperation with VTT Oy and TEKES (the Finnish Funding Agency for Innovation). The results were implemented in Eneron that now contains totally new methods for bench-marking and comparison of building energy data.

Eneron and ISO 50 001

We also wanted to demonstrate to our clients the conformity of our service to the international standard ISO 50 001:2011 Energy Management System. Bureau Veritas, one of the world's most respected inspection and certification bodies, issued a verification statement of the Eneron platform to this standard in 2014.

We believe that well communicated expert services, efficiency and high quality created by concepts and predefined processes, lead to positive customer experiences. Our systematic measurement of customer satisfaction and continuous development of the delivery process, ensure and continue to strengthen the competitive advantage. It is fun and mutually beneficial to improve and develop together.
