Can go through the building construction, type and condition. Cover the building services, water, electrics, heating/ventilation, air-conditioning etc, and equipment used. All in a very easy manner which any person can understand, and explain over the phone. From this information, a report can be written to cover the advice on where energy can be saved. The report then emailed or posted to the client.

Visit the site to view the condition of the property and equipment used, to collect copies of the documentation on energy and water used. To discuss with the personnel responsible for the building services, to get insight into how the equipment performs. Produce a report advising on the areas where energy can be saved, with recommendations on how to go about making savings.

Given the full details of the process, calculations can be made on the amount of energy that can be recovered. Advice can be given on how the energy can be used within the same process or other process.
Exhaust gas heat into inlet gas heat, hot water or steam if possible.

Design and specify equipment required to recover identified waste energy. Identify where recovered energy can be integrated into other processes.

Many control systems are either designed incorrectly, installed incorrectly or are not tuned correctly.
Most controls are not commissioned correctly, having been installed and left in the factory settings.
Badly tuned controls can be worse than no controls, by wasting energy, warring out equipment within the system by constantly oscillating valves, dampers, variable speed drives, etc.

When the controls are badly set, the set point has to be set further away from the desired position, to avoid going into, an area where the process will damage the product. The result of the poor setting is that the process will go to higher temperatures, higher process flows, etc, thus wasting energy and or product.
