Air handling unit Ventilation system for large-scale use in residential, office and business premises. Outside air is supplied to the rooms and "used" or polluted exhaust air is discharged. It transports, filters, heats, cools and disinfects the air.

Artemis Beteiligungen I AG Affiliated company that is controlled by Michael Pieper and has been the main shareholder in Arbonia AG since December 2014.

Building Information Modeling (BIM) Describes a method of networked planning, execution and management of buildings and other constructions with the help of software. All relevant building data is digitally modelled, combined and recorded. The structure is also geometrically visualised as a virtual model.

Cash flow Positive or negative surplus cash arising from commercial activity, measured over a certain period. Cash flow can be used to evaluate how financially strong a company is.

Cash flow from operating activities Describes the liquid funds generated by the business activity in a given period. The operating cash flow includes the net income for the year, changes in depreciation, amortization, provisions and current assets.

Combined heat and power (CHP) The simultaneous generation of mechanical energy and usable heat produced in a joint thermodynamic process. The mechanical energy is usually converted directly into electrical power. The heat is used for heating purposes. The advantage of CHP is the reduced fuel requirement for simultaneous electricity and heat production, which greatly reduces greenhouse gas emissions. CHP can be used with almost any fuel and heat source.

Computerized Numerical Control (CNC) Refers to an electronic process for controlling machine tools which, through the use of control technology, are capable of automatically producing workpieces with high precision, even for complex shapes.

Controlled residential ventilation A mechanical form of ventilation, used for ventilating residences with heat recovery. An integrated heat exchanger is used to transfer heat energy from the exhaust air to the outside air supply. Residential ventilation ensures that air is replaced in the building at a defined rate, creating a hygienic means of air exchange.

EBIT Earnings Before Interests and Taxes: a company’s operating results before interest and taxes are taken into account.

EBIT margin Indicates EBIT in relation to revenue.

EBITDA Earnings Before Interests and Taxes, Depreciations and AmortiSation: a company’s operating results before interest, taxes, depreciation and amortisation are taken into account. EBITDA is one of the most meaningful figures in evaluating a company’s earning power.

EBITDA margin Indicates EBITDA in relation to revenue.

Employer branding A strategic corporate measure to present a company as an attractive employer. The goal is essentially to permanently increase the efficiency of personnel recruitment as well as the quality of applicants due to the marketing effect. In addition, qualified and committed employees are to be tied to the company in the long term through a higher level of identification and the development of an emotional bond.

Equity ratio Indicates the shareholders' equity in relation to total capital. It is used to assess a company’s financial capacity and stability. If the equity ratio is high, you can assume that the company is less dependent on third-party funds.

Fan coil Depending on the temperature of the flow water for a connected water heater/chiller, fan coils are able to heat, cool and dehumidify a room, and are able to provide ventilation and the option of filtering indoor air. This results in maximum comfort with optimum room air quality. A fan radiator is able to heat (but not cool) a room by means of convection when the fan is switched off.

Free cash flow The operating cash flow minus cash flow from investing activities; illustrates how much cash remains free for shareholder dividends and/or any repayment of debt financing that may be required.

Heat pump Draws its heat energy from the air, groundwater or soil, and uses this extremely efficiently to generate the heat required for heating drinking water and rooms. Compared to heat pumps, no other kind of heat generator is a more environmentally sustainable solution or is more fit for the future.

Laminated safety glass Consists of two or more glass panes joined together with highly tear-resistant, tough-elastic intermediate layers. In the event of mechanical overloading by impact and shock, the glass breaks, but the fragments adhere to the uninjured intermediate layer. This reduces the risk of injury and the glazing retains a residual stability.

Manufacturing ExecutionSystem A level of a multilayer production management system that operates close to the process. Compared to similarly effective systems for production planning, the so-called ERP systems, the MES is characterised by the direct connection to the distributed systems of process automation and enables the management, guidance, control or monitoring of production in real time. This includes classic data acquisition and processing, but also all other processes that have a real-time effect on the production process.

Market capitalisation A company's stock market value. It is calculated using the number of shares x the current share price.

Net debt The total that remains when cash and cash equivalents are deducted from non-current liabilities. This expresses how much money would be needed to repay loans if the liquid assets were already used up and the company had to liquidate fixed and current assets.

Product Information Management (PIM) The provision of product information for use in different output media or distribution channels as well as for different locations. The prerequisite for this is the media-neutral administration, maintenance and modification of the product information in a central system in order to be able to supply each channel with consistent, accurate information without a large expenditure of resources.

Redox flow technology Storage technology based on vanadium in which electrical power can be stored. This storage technology is particularly climate-friendly, as it does not require rare materials and conflict raw materials, is fully recyclable and also has a high level of operational reliability and durability.

Science Based Targets Initiative (SBTi) An initiative of various organisations that sets reduction targets for greenhouse gas emissions. It specifies how much and how quickly a company must reduce its greenhouse gas emissions in order to limit global warming to below 1.5 °C in accordance with the Paris Agreement.

Security Information and Event Management (SIEM) Performs real-time analysis of security alerts from various sources, applications and network components to serve an organisation's computer security.

Security Operations Centre (SOC) A central point of contact that monitors, detects, analyses and resolves security incidents 24 / 7.

Single-pane safety glass (ESG) A glass in which a strong internal stress is built up by heat treatment. This significantly increases the impact and shock resistance compared to normal flat glass.

Social engineering Interpersonal influence with the aim of inducing certain behaviour in people, for example, to disclose confidential information, to buy a product or to release funds.

Softforming In this process, a profile is milled onto an already coated panel, which is later coated with a special edge banding machine. This creates a joint at the point where the panel coating meets the edge. This contrasts with the postforming process, in which the profile is coated with the same coating as the panel after the milling process, so that no joint is created.

Stratified buffer storage Ensures that heat generation and heat consumption are decoupled. This means that heat can be generated independently of the time of consumption. The heat pump does not have to restart every time the radiator is turned on, for example. The stratified buffer tank therefore stores the heat energy generated by the heat pump and transfers it to the heating system and to the domestic hot water.

UN Global Compact A worldwide pact made between companies and the UN to make globalisation more social and ecological. These companies undertake to comply with certain minimum social and ecological standards.

Volume-weighted average price (VWAP) Indicates the volume-weighted average price of a security in a given period.
