Becoming more energy efficient is important for organisations aiming to reduce their environmental impact, and as a means of reducing energy bills and making financial savings.

Data loggers can be a useful tool in helping organisations monitor energy consumption in line with energy management regulations. Data loggers provide energy usage data, as well as temperature, humidity, CO2, count and other environmental information.

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment and energy saving identification scheme for large undertakings (those that have ISO 50001 Energy Management System are exempt).

ESOS is being established by the Department of Energy and Climate Change (DECC) in response to the requirement for all Member States of the European Union to implement Article 8 of the Energy Efficiency Directive. In simple terms, an ESOS Assessment requires participants to do three things:

1. Measure total energy consumption across their buildings, transport and industrial activities.
2. Conduct energy audits to identify cost-effective energy efficiency recommendations.
3. Report compliance to the Environment Agency (as the scheme administrator), and keep records.

Energy Data Loggers can help meet the requirements of ESOS, monitoring energy usage and identifying areas of significant consumption. Data can be used to determine how and where energy is used, to identify energy consumption changes over time, and to identify energy usage patterns and opportunities for reduction - all of which can lead to cost savings.

The Tinytag Energy Logger is a portable and easy to use device for recording energy consumption. It accurately records single and three phase power usage, and can be used to:

• monitor at the board level and individual pieces of equipment
• build energy consumption profiles
• identify variations in energy usage, both over time and between different areas
• identify faulty equipment or high-consumption areas, allowing efficiency saving to be made

Data loggers in the Tinytag range also monitor temperature, relative humidity, CO2, voltage, current and count. ESOS has some suggestions on common energy savings opportunities, and Tinytags can be used to help provide information in many of these areas. For example, this can include monitoring the performance of HVAC systems, the efficiency of building materials (e.g. insulation), the efficiency of equipment such as boilers and refrigerators, and helping to assess before and after performance of replacement lighting and heating systems.
