Air conditioning – split units Split systems are a type of air conditioning systems that consist of an indoor (evaporator) and an outdoor (condensator) unit.
Central heating systems A central heating system generates heat (hot water) at one central point (boiler) and transfers it to multiple rooms of a building or premises through pipes and radiators. The best temperature for each room can be regulated by means of thermostats. This leads to an optimization of the heating demand of the building and a reduction of the energy costs during the year.
CFL: Compact fluorescent lamp A compact fluorescent lamp (CFL), also known as energy saving lamp, is a type of fluorescent lamp that can consume 80% less electricity than a conventional light bulb for the same amount of light.
Chiller Chillers are components commonly used in central AC systems. Its function is to cool the refrigerant fluid (mainly water), which is distributed to terminal devices and cool the air in the respective spaces.
CNC machines
(computerized numeric control)
CNC machines are operated by using a computer and are fully automated. The working process and the final product are defined by a program.
CNC machines are more productive and improve the quality of the final product, which leads to reduced energy costs, better product prices and higher profitability per produced unit. Common types of CNC machines are lathe, drill, laser cutting, press machines, etc., which can be found in metal, plastic or wood processing industries.
EE: Energy Efficiency Energy efficiency can be defined as the reduction of the energy used to provide a certain amount of goods and services, or to obtain a certain degree of confort. It also can be the increase of productivity or confort levels under maintaining or slightly increasing the amount of energy needed for such purposes.
Edge-banding machine A machine for furniture production that covers or bonds plywood, particle boards or similar wood borads with edgebanding materials like PVC, acrylic or melamine, etc.
EPS: Expanded Polystyrene EPS is a common thermal insulation material for buildings. It is a type of polystyrene (commonly known as stiropor)
EER: Energy Efficiency Ratio An indicator that shows the ratio between the cooling power (in Watt) of and the electricity consumption (in Watt) of a refrigeration or cooling equipment.
The higher the EER, the more efficient is a refrigeration equipment.
Example: If an air conditioner is rated with 3,500 Watt and consumes 1.000 Watts of electricity per hour, its EER is 3.5
Emissions certifications
(e.g. EURO 5 and 6; TIER III)
Most new vehicles, construction or agriculture machinery have now certifications regarding the emission of certain gas and particles like soot, carbon monoxide, nitrogen oxide, etc. Vehicles that have these certifications produce generally less pollutants and consume less fuel than those without certifications.Well-known certificates are:
  • EURO Certification: mandatory in the European Union
  • TIER II: mandatory in the USA
Energy audits An energy audit is a survey and analysis of energy flows and uses in a building, process or company. The final objective of an energy audit is to optimize the energy consumption without negatively affecting the output. For example, an energy audit can identify cost effective ways to reduce energy losses and achieve energy savings.
Energy labels
(Categories A, A+, A++, A+++; Energy Star)
Energy labels indicate if a device is energy efficient compared to similar devices. This can be found in office equipment, consumer electronics and appliances. The best known examples are:
  • Energy classes: Mandatory energy label in the EU. The energy efficiency of equipment is categorized into classes from A+++ (most efficient) to D (least efficient).
  • Energy Star: Voluntary certification for equipment made in the USA. If a device has the Energy Star symbol, it is usually 30% more efficient than conventional equipment.
Fermentation chamber Bakery equipment consisting of a chamber with controlled humidity and warm temperatures inside that increase the activity of the yeast resulting in a higher, faster rise of dough.
Heat pumps Heat pumps are devices that drive the heat from a renewable heat source (soil, water or air) to another space (a building), by using some electricity.
ISO 14001 The ISO 14000 is a group of international standards that provide a framework that helps organizations to create an environmental management system. In the end, the environmental management system aims at minimizing the own negative environmental impact, complying with the existing environmental legislations, and to continously improving the own environmental performace.
LED: Light-emitting diode LEDs are lighting applications that present many advantages over conventional bulbs including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching.
Organic production/farming Organic farming aims to minimise the harmful human impact on the environment. Organic farming usually includes e.g. crop rotation, avoidance of synthetic pesticides, fertilizers or antibiotics, avoidance of hormons or food additives, prohibition of genetically modified organisms, etc.
PV: Photovoltaic systems Photovoltaic solar panels usually consist of thin cells of silicon that convert sunlight directly into electricity by means of the photoelectric effect.
Profile machine A woodworking machine that used to shape wood (profiles) by using special cutter heads
Reactive energy compensators These devices help to increase the power factor (which measures the correct use of electricity in a company) and reduce the energy losses in companies with high electricity consumption. The incorporation of this device to the electrical system of a company reduces electricity costs and avoids paying penalties to the utility for low power factor.
RE: Renewable Energy Renewable energy comes from natural energy sources and exist in almost unlimited amounts (e.g. wind, sunlight, hydropower, geothermal energy), or replenish more quickly than they are consumed (e.g. biomass)
SWHS: Solar water heating system SWHS use sunlight to produce hot water. These systems have primarily a thermal collector (which in most cases consists of a flat metal plate or evacuated glass tubes), a piping system and water storage tank.
VSD: Variable speed drives Variable speed drives (VSDs) are devices that control and change the speed of an electrical motor by regulating the amount of energy which enters the machine. By this way, VSDs save energy. VSDs may be suitable for pumps, milking machines, conveyor belts, ventilations systems, saws, etc.
