Effective integration of technical systems is the key to energy efficiency and optimal operation in modern buildings. At SustEvo, we offer complete ITB services and project management to ensure smart, operationally efficient and sustainable solutions. Integrated technical building installations (ITB) and good project management are crucial to ensure energy efficiency and optimal operation in modern buildings.
The NS3935 standard defines clear roles for integrated technical building installations (ITB). At SustEvo, we can provide ITB managers, RITBs and system integrators who ensure seamless interaction between technical systems in your projects.
By integrating ITB into your project management from day one, you avoid errors, reduce operating costs and ensure optimal performance over time. Our specialists ensure that the systems are designed, installed and commissioned correctly – so that the building functions optimally from day one.
The goal is to ensure holistic, operationally efficient and sustainable solutions through a structured ITB process. We at SustEvo can deliver all roles according to the NS3935 ITB standard. Contact us for help meeting your needs in your project.

Good energy management in a construction project is a critical factor in achieving energy-efficient and sustainable buildings. This involves systematic planning, implementation and follow-up of energy-related measures throughout the project's phases - from early design to completion. By integrating energy management into decision-making processes and technical solutions, one can optimize energy use in both construction methods and material selection, as well as ensure that technical installations are dimensioned and managed correctly. The use of energy budgets, energy frameworks and dynamic simulation tools provides decision support and documentation that the building meets requirements according to TEK and relevant certification schemes such as BREEAM or FutureBuilt.
After the building is handed over, it is crucial that energy management is continued in the operational phase to ensure that the energy targets are actually achieved in practice. This requires that the building's energy performance is monitored through continuous measurement, analysis and adjustment of operations – for example, through the use of SD systems, energy monitoring systems (EOS) and regular energy audits. In many cases, a significant deviation is seen between calculated and actual energy use, often due to inadequate training, errors in control systems or operating routines that are not adapted to the building's function. A systematic approach to energy management in the operational phase contributes to reduced operating costs, lower greenhouse gas emissions and increased service life of technical installations – while providing the owner and users with confidence that the building is performing as expected.
