Requirements and Criteria Type: 
  • Technical Specification (Requirement Specifications)

Main Objective: 

Motive

A building's calculated energy needs and actual energy consumption often do not match. There can be many reasons for this, but most often it is due to changed conditions.

Argument

A central operational control system (COCS) can be an important tool for finding out why energy consumption differs from the calculated figure. A COCS provides a basis for both efficient energy use and good utilisation of operating resources since data from all of the technical installations is available online via the internet. A COCS is a good tool for the day-to-day operating and monitoring of technical systems. The building should therefore be designed for good energy management and control. This means a building must have components and systems that make it possible to analyse energy data and monitor energy use during operation so that you can identify unnecessary energy use and implement measures to reduce the energy used.

Requirement Specification: 

The design project must include a central operational control system (COCS) that encompasses all the major technical installations in the building. It must be possible to integrate the system into a top level system.

A top level system means a central system that links together management and control of multiple buildings in an organisation, such as a municipality or agency.

The COCS must:

  • Manage, control and monitor all of the building's technical systems
  • Be an aid for the operating department that allows them to operate the systems simply in a correct and efficient manner
  • Continuously adjust the energy used to the actual needs so that the building does not use more energy than necessary
  • Enable power management

The selected solution must be documented by:

  • Defining all of the systems that must be linked to the COCS
  • A topology diagram showing the communication level between all systems, from sensors via sub-exchanges up to the top level system, as well as the connection of the building's technical network
  • A description of the data flow in the automation system, collection and exchange of data
  • a system for communicating with users

Requirements must be defined for technical specifications and a communication platform that ensures that every building can be linked to a central top level system so that important functions can be monitored and controlled in a single system. This allows the collection and presentation of operating information from multiple connected buildings. This makes it simpler to monitor operation or change operating parameters, and faults will be identified faster. If the organisation already has a top level system, it is important that the COCS works with all of the functions the organisation's top level system already has.
