ISO 50015: Implementing the measurement and verification of energy efficiency correctly

ISO 50015

Information on ISO 50015: Principles and guidelines for energy management Improving energy efficiency has long since become a key competitive factor for businesses. However, savings alone are not enough—they must also be measurable, traceable, and reliably verifiable. This is precisely where ISO 50015 comes in. The standard provides a structured framework for measuring and verifying […]

Saving on heating energy: Practical tips on heating and how to reduce your heating bills

Saving on heating costs

Ventilation, windows, insulation, a new heating system – what really helps? Saving on heating costs: Rising energy prices and growing environmental awareness mean that efficient heating is more important than ever. However, many households and businesses are not yet making the most of their heating systems’ full potential for savings. Yet even simple measures can […]

ISO 50006 – Energy performance indicators, baseline energy consumption and energy efficiency explained in simple terms

ISO 50006

Energy performance indicators and assessment of energy-related performance Nowadays, an effective energy management system is much more than just a tool for cutting costs. In the face of rising energy prices, increasing regulatory requirements, and growing pressure to be sustainable, it is becoming ever more important for companies to systematically record, evaluate, and specifically optimise […]

Investment in energy efficiency and efficiency measures: top returns for 2026

Efficiency measures

Lighting, compressed air or heat generation: saving energy through efficiency measures Many companies are regularly faced with the question of which projects to invest in to ensure long-term financial success. The focus is often on new production facilities, digitalisation or the expansion of business areas. However, one area is frequently underestimated, even though it plays […]

Physics Explained: The difference between calorific value and net calorific value, explained in simple terms

calorific value

How much energy is contained in the fuel for my heating system: efficiency, performance and heat of condensation? Whether assessing heating systems, analysing energy consumption, or comparing different energy sources, the terms ‘calorific value’ and ‘net calorific value’ play a central role in energy technology. Nevertheless, they are often confused or misinterpreted. Both metrics describe […]

Physics Explained: The Efficiency of Synthetic Fuels (E-fuels, Hydrogen)

E-Fuels

Synthetic fuels: Are they carbon-neutral? E-fuels are seen as a beacon of hope for a climate-neutral future – particularly in areas where direct electrification is difficult. They can be produced from renewable energy sources and make use of existing infrastructure, which reduces the transition costs for the system as a whole But beyond application scenarios […]

Calculating total final energy consumption under the Energy Efficiency Act (EnEfG) – Which consumption figures are relevant, and which can be disregarded?

Total energy consumption

Important exceptions when calculating total final energy consumption in accordance with Section 8 of the Energy Efficiency Act We have already written about the importance of calculating a company’s total energy consumption in other blog posts (for example, here and here). However, in day-to-day practice, it is often the case that calculating total energy consumption […]

Physics explained simply: How does a heat pump work?
