Audit of energy saving solutions

Any audit is a first step towards clarity and solutions. Traditionally, resource and energy efficiency solutions are very complex and cover many areas. Approached from only one angle, the information is incorrect, the results are inaccurate, and instead of improving the situation, the end result may even worsen the situation.

The audit begins with the collection of source data, in the framework of which it is important for the contracting authority to provide source data that is as accurate and up-to-date as possible. The more accurate the source data, the more accurate the payback periods, energy cost estimates and solution costs calculated in the final audit.

Mapping and measurements

In order to analyse and map the building data, the relevant experienced engineers will be involved in the project, who will work through the source information and, during the mapping, assess the current state of the technical systems and identify solutions to improve the existing situation. Unlike a classic energy audit, the audit of energy saving solutions involves various measurements, including indoor climate (temperature, CO₂, relative humidity), light levels in rooms and workplaces, random thermography, faucet and shower water consumption, electricity consumption and measurements of the proportion compressed air leakage or already mapping in industrial plants. Based on the results, solutions with a reasonable payback period are prepared for the customer, which, depending on the field, help to save 40-90% of energy costs.

Training and implementation

The audit service includes the presentation of a summary of the completed work and training on the proposed solutions so that our client does not receive another classic energy audit, which typically establishes the facts of the current situation, but does not offer a specific solution, payback periods and action plan.

The audit of DeltaE Engineering provides the client with specific solutions to improve the condition of the technical systems and proposes a further work plan based on the priorities. In addition, the audit provides a thorough overview of the energy consumption of each complex and the trends in electricity consumption.

After the contracting authority’s training, the client can decide whether to invest in the implementation of the solutions oneself or with our help. We are ready to finance our own solutions. We are so confident about savings!
