OVERVIEW - Operational Management: International and European Know-How

This overview article describes a number of initiatives for managing building energy consumption. The projects discussed concentrate on different phases of a building’s energy usage, from commissioning to post-occupancy. Approaches include the monitoring and management of energy use within a building and the study of relationships between energy experts and building users.

The importance of commissioning in the international context

The process of commissioning comprises several different functions. These include: clearly identifying the owner’s requirements, monitoring the progress of the project in consultation with those involved, and ensuring that the work is being completed to a high standard. There are several international energy commissioning projects, e.g. Annex 40 and Annex 47 of the Energy in Buildings and Communities Programme (IEA-EBC) of the International Energy Agency.

 

Re-commissioning: a systematic approach!

You can save 10 % of energy costs without large investment. This approach will improve your working environment and enable you to stay in line with regulations for improving energy efficiency in buildings.

Re-Commissioning is a systematic approach to examining building equipment systems, their operation and maintenance procedures, and interactions with building occupants. In order to achieve performance specifications, improvement measures are developed, implemented and followed up with quality assurance procedures. Of particular importance is an interdisciplinary perspective: besides technical issues, economic, financial, organisational and legal aspects are investigated and accounted for. It is based on five key components:

 

What about the inspection of HVAC systems?

iSERVcmb challenges building owners and facility managers to improve HVAC system monitoring and achieve substantial energy savings.

The project iSERVcmb (inspection of HVAC Systems through continuous monitoring and benchmarking) has shown that better understanding of building services can lead to substantial reductions in overall building energy consumption. Reductions in electricity consumption of between 19 to 33 % have been achieved in buildings using the iSERVcmb approach. The system consists of a spreadsheet to collate the information required and then a database to provide feedback. The database contains information for HVAC systems from all over Europe. The approach has the potential to reduce EU electricity use as a whole by up to 4 %, with many of the savings achievable for little or no financial outlay.

 

In the social housing stock…

The AFTER project enables European social housing organisations to optimise their energy performance through the effective management of their housing stock. Specifically, AFTER investigates two important relationships: the contractual arrangement between heating providers and facilities management companies, and the relationships between these companies and their tenants.

In order to develop the best housing management practices, AFTER partners are implementing three energy saving measures in three pilot buildings owned by European Social Housing Companies (France, Czech Republic and Denmark). The objectives of the project are improving social housing organisations’ awareness and knowledge on energy saving measures, reducing short term energy consumption of buildings, increasing tenant involvement in reducing energy consumption and developing strategies linking energy efficiency and low cost investment.

As mentioned in the last AFTER newsletter, a first evaluation of the results will be presented after the end of the implementation process in December 2013.

 

From inspection to domestic advice by service companies

Who is better able to provide advice to users than the professional who controls the system? MOVIDA project has involved different categories of inspectors and tested their capability to provide advice to users, based on an automatic generation of recommendations. The tool for generating advices was initially developed in the Netherlands (Installatie Performance Scan). Several hundred heating and cooling systems have been visited, recommendation reports delivered, and results evaluated by statistical analysis and a market survey. Users appreciate the additional service, and the inspectors develop the market to future interventions.
