What is Weather Adjusted Energy Data?
Weather adjusted energy data establishes a baseline of energy used by your business for its operational requirements. Weather adjusted data factors out the energy used by your business on heating or cooling. It’s also known as “weather normalisation” or “weather correction”.
Why is Weather Adjusted Energy Data important?
In short, weather adjusted data will allow you to see if your energy-saving measures have had a real impact on your baseline energy. Weather adjusted data gives you your baseline energy by separating your operational energy consumption away from energy used to meet heating or cooling demand.
Understanding your baseline energy gives energy managers a clearer indication of the energy that’s required for business operations. This allows energy managers to assess the effectiveness of any practical energy-efficiency measures introduced, and to see if their measures have had the desired impact on their baseline energy by separating the variable energy consumption caused by weather changes.
Energy managers will be aware that there isn’t always an easy way to know if any steps taken to reduce energy consumption have actually worked. Establishing a baseline energy profile for your business is made difficult due to weather conditions increasing heating and cooling demand.
Using ALPHA. Lite to manage your energy data.
ALPHA. Lite is a quick and easy subscription-based software which remotely analyses the last 14 months of your energy data, without any intrusive hardware – something no other platform is able to do.
ALPHA. Lite, with its built-in Weather Adjusted Data parameter, will apply the global industry standard of Degree Day Analysis to your data to very quickly reveal your baseline energy consumption – all within two minutes of signing up.
ALPHA. Lite: A Case Study for Weather Adjusted Energy Data
The following is a Case Study demonstrating the insights that ALPHA. Lite can offer its subscribers. This example uses data from January 2019 at a site in Milton Keynes, which had an average temperature of 5 degrees C. To evaluate its consumption, the data is compared with another site operated by the same client under similar conditions.
January 2019 – Milton Keynes Site. Average temperature 5 degrees C.
Table 1 shows a client using 38% of their overall consumption on heating energy alone, at 40,010 kWh. In Milton Keynes, with an average temperature of 5 degrees C in January 2019, this client consumed a total of 105,088 kWh. After correcting the data to factor out heating energy, the weather adjusted baseline consumption was 65,079 kWh.
Table 1: January 2019 – Milton Keynes Site: Overall Consumption, Weather Adjusted Consumption and Heating Energy.
Figure 1 and Figure 2 demonstrate the level of insight which ALPHA. Lite provides, showing the client’s baseline consumption at a daily average of 2,099 kWh.
Figure 1: Daily breakdown on Overall Consumption.
When this data is compared to a similar site operated by the same client in Liverpool (Table 2), with the same outdoor temperature, ALPHA. Lite revealed 24.6% less efficiency in Milton Keynes’ baseline consumption. The data encourages the client to take practical, energy-efficiency measures to reduce their baseline consumption.

January 2019 – Liverpool Site. Average temperature 5 degrees C.
Table 2 shows a similar site which uses 13.4% of their total energy on heating, despite having similar weather conditions. Energy efficiency measures have proven to be successful at this site, as the client was able to operate their site using 23% less overall consumption than Milton Keynes.
This client could implement similar energy efficiency measures from their Liverpool site to reduce their consumption in Milton Keynes, resulting in improved sustainability and overall cost-effectiveness across more of their sites.

With a subscription to ALPHA. Lite, businesses can instantly get detailed insights into multiple sites’
consumption over the past 14 months. This process used to be invasive and lengthy, often requiring site visits and expensive hardware. But with ALPHA. Lite’s cloud-based technology, you can now monitor your business’ consumption remotely with just a few clicks.
ALPHA. Lite is dedicated to helping businesses minimise energy wastage and improve their carbon footprint. The ultimate goal is to achieve net zero carbon.
That’s why subscription is just £15 a month with no contract ties. You can sign-up for as long as you like and ensure your business maximises its efficiency. It’s never been so rewarding to manage your energy.
