How Gemini Data Loggers can make buildings greener and more energy efficient

  • 9 Aug 2023

Before-and-after power/energy usage analysis is vital in energy audits and for organisations to validate energy-saving plans. Gemini Data Loggers designs and manufactures comprehensive building monitoring equipment, including temperature and relative humidity data loggers for assessing occupant comfort, data loggers for monitoring energy usage and efficiency, and carbon dioxide data loggers for monitoring indoor air quality.

Hundreds of public buildings throughout England will cut their use of fossil fuels and save millions of pounds on energy bills thanks to funding from the government’s Public Sector Decarbonisation Scheme (source: GOV.UK). The scheme aims to cut emissions from public sector buildings by 75% by 2037 (compared to 2017 levels).

Powered by cheaper and cleaner renewable energy, Phase 1 of the scheme ‘aimed to support up to 30,000 jobs in the low carbon and energy efficiency sectors and reduce carbon emissions from the public sector’.

Phase 2 then provided ‘£75 million of grant funding for the financial year 2021/2022’, supporting the ‘public sector in taking a whole building approach when decarbonising their estates’.

Now onto Phase 3, the scheme is providing ‘over £1.425 billion of grant funding over the financial years 2022-2023 to 2025-2026’. The next round of applications, for Phase 3c of the scheme, will open in Autumn 2023.


The Tinytag Energy Logger

For a small investment of £995, the Tinytag Energy Logger provides businesses with information about significant areas of energy usage, leading to energy savings. Recording data before energy-saving implementation can inform your strategy by revealing areas of high power consumption that could be easy to reduce, as well as the peak times for energy usage in your facility.

Data recorded after energy-saving plans are executed verify the energy savings of the methods in place, providing useful historical data to refer back to and report on.

Bedford Hospital, run by the Bedfordshire Hospitals NHS Foundation Trust, uses the Tinytag Energy Logger as a key tool in electrical monitoring. The hospital is a local acute trust which also provides many outpatient services on-site, including a branch of Moorfield’s Eye Hospital serving Bedford and the surrounding area, and hosts a large base for GSTS Pathology, which provides services to several hospitals across the East of England.

For a site of this size and scope, accurate monitoring of power usage and energy efficiency is of ongoing importance. The data from the Energy Logger is used to confirm if upgrades to infrastructure are needed or if energy-saving measures are to be deployed and verified.

Tinytag data loggers can evaluate a range of building projects, such as in the Post-Occupancy Evaluation (POE) of certified Passive House buildings. The Tinytag Ultra 2 (TGU-4500) temperature and relative humidity data logger was crucial in this project for understanding how the Passive House building performed in real, lived-in conditions.

Data from the Ultra 2 logger reveals the average indoor temperature over the year was 20.5°C, matching Passive House requirements, and the average relative humidity was a comfortable 47.4% (within the recommended range).
