Energy screening is a thorough study of an installation on a technical and energy level, whereby technical problems are detected and analysed, among other things. This can be carried out for new or existing installations.

Each screening report includes a master plan in which different proposals are compared on a technical and financial level (cost/benefit ratios), including the calculation of the pay-back period of the investment.

Typical installations that are the subject of energy screenings:

steam production,
compressed air production,
cooling (both positive and negative, either based on direct expansion (HFC, ammonia) or ice water/glycol),
heating,
ventilation,
air conditioning,
lighting,

Can also be taken into consideration:

processes (dryers, cooling tunnels, packaging lines, cogeneration, ...),
energy media and utility ducts.

In short, energy screening consists of the following phases:

inventory of energy consumers,
on-site checking of functional diagrams,
carrying out measurements and determining the characteristics of consumers,
mapping out energy flows,
analysis of existing installations / determining the needs for new installations,
cost-benefit analysis and calculation of pay-back period,
determining the distance to the world top and drawing up an Energy Plan (according to the mission),
developing the master plan (according to the mission),
drawing up the screening report.

Within the framework of the Benchmark and the Audit Covenant, screening is defined as a systematic inventory of the possibilities to achieve energy savings within a company. It is a study, possibly supported by measurements, tests, experiments or other means to establish the energy consumption or saving. With respect to a normal screening, for the Covenant, the distance to the world top must also be established and an Energy Plan must be drawn up. This Plan indicates for the different process installations how, and how fast, the world top for energy efficiency will be reached.
