Building energy efficiency 

Improving building energy efficiency is a crucial aspect of sustainable development and environmental conservation. It involves implementing measures to reduce energy consumption and minimise waste in residential, commercial, and industrial buildings.

What factors influence a building's energy efficiency?

The factors affecting a building's energy efficiency below fall under our building energy audit.  

Insulation and Weatherisation:

  • Proper insulation of walls, roofs, and floors helps regulate indoor temperatures, reducing the need for excessive heating or cooling.

  • Weatherisation measures, such as sealing gaps and cracks, prevent air leakage, maintaining a more consistent indoor environment.​

Energy-Efficient HVAC Systems:

  • Upgrading heating, ventilation, and air conditioning (HVAC) systems to high-efficiency models can significantly reduce energy consumption.

  • Regular maintenance and cleaning of HVAC systems improve their efficiency.


Energy-Efficient Lighting:

  • Transitioning to LED or other energy-efficient lighting technologies reduces electricity consumption and extends the lifespan of lighting systems.

  • Incorporating sensors and automation for lighting control ensures that lights are only on when needed

Smart Building Technologies:

  • Implementing smart building management systems allows for better control and optimization of energy use.

  • Smart thermostats, occupancy sensors, and automated systems can adapt to occupancy patterns and adjust energy usage accordingly.


Energy-Efficient Windows and Doors:

  • Installing energy-efficient windows with proper glazing and seals helps control heat transfer and maintain indoor comfort.

  • Energy-efficient doors and windows also contribute to reducing the load on HVAC systems.

Renewable Energy Integration:

  • Incorporating renewable energy sources such as solar panels or wind turbines can offset the building's electricity demand.

  • On-site renewable energy generation contributes to sustainability goals.

  • We can advise on renewable energy integration as part of our Capital Investment Strategy

Energy Audits and Monitoring:

  • Conducting regular energy audits helps identify areas for improvement and assess the overall energy performance of a building.

  • Continuous monitoring of energy usage allows for proactive adjustments and optimisation.

Occupant Behavior and Education:

  • Educating building occupants about energy-efficient practices and encouraging energy conservation behaviours can contribute significantly to overall efficiency.

Lifecycle Cost Analysis:

  • Considering the lifecycle cost of building materials and technologies helps make informed decisions, as upfront costs may be offset by long-term energy savings.

What is involved in a building energy audit?

  • Our energy saving specialist will visit your building and do a walk around with the facility manager.

  • We will analyse the energy performance of your building using invoice and meter data.

What will you get from working with Pilio?

  • ​A report and presentation to share with key decision-makers.

  • Recommendations for energy management and investments for energy efficiency and renewable technologies.

  • Suggested next steps for saving energy.

  • A license to Pilio's energy saving tool for ongoing building monitoring and management. 

These audits are compatible with the British standards for energy auditing.

Pilio has performed over 250 building energy audits across a variety of commercial buildings including ACO Technologies, Fabrix, English National Opera, National Theatre, Tullie House, and YMCA.
