Building standards regarding energy efficiency are increasing at their highest rate ever. Experts across the construction industry are searching for new ways to boost a building’s thermal performance and reduce carbon emissions. Much of the focus has usually surrounded new-build properties with Passivhaus Standards creating the benchmark.

The Passivhaus Standard, however, was put in place to focus on improving energy performance and focused entirely on new build projects. The fabric and structure of a Passivhaus building is chosen and designed to enhance thermal performance. However, with retrofit or renovation projects, the high Passivhaus standard wasn’t always achievable, and therefore EnerPHit was created.


What is the EnerPHit Passivhaus retrofit?

 EnerPHit is a quality approved retrofit with Passivhaus components certification. This certification sets a slightly different standard in comparison to a new build project to allow for existing property orientations and thermal bridges. EnerPhit focuses on fixed aspects of existing buildings. This includes elements such as:

  • External walls
  • Roofs
  • Top floor ceilings
  • Windows
  • External doors
  • Thermal bridges
  • Ventilation
  • Electrical efficiency of ventilation systems

The Passivhaus Institute recognises that many older buildings can’t pass the original Passivhaus standards. The EnerPHit certificate allows renovations of older properties to the rigorous Passivhaus standards giving existing buildings the ability to achieve high energy efficiency and reduce energy demands by up to 90%. Some EnerPHit reports have even achieved an impressive 93% reduction in energy loss.

Why is EnerPHit needed?

 In 2019, the UK government pledged to reduce the country’s carbon emissions to net-zero by 2050. This legislation has transformed the construction industry’s approach towards building design. Products such as Green Life Building’s SIP panels look set to play an instrumental role in the future of house building and property renovation, helping developers meet the required thermal performance standards.

SIP panels can be retrofitted into an existing property and can be used to meet EnerPHit standards. Retrofitting or renovating an existing property by the EnerPhit standards can reduce your annual heating energy requirements and carbon dioxide emissions by 75%-90% in comparison to the average existing building. By following the EnerPHit standards for retrofit properties, your project will benefit from increased insulation and improved airtightness. This will provide thermal comfort and reduce the risks of surface condensation and mould growth. It will also help to reduce carbon emissions and create a more energy efficient building, with lower ongoing costs.



What are the benefits of retrofits that are in line with the EnerPHit certificate?

 At GLB, we strongly believe the EnerPHit certification gives strong incentives for homeowners and commercial property developers. The cost of achieving the standards is far outweighed by the long-standing savings received by investing in your future energy efficiency. Some benefits of renovating a property with GLB:

  • Energy bills are greatly reduced
  • Contribution to energy security
  • More comfortable living conditions
  • Increased property value
  • Reduction in carbon footprint

With an EnerPHit retrofit, a property can achieve comfortable ambient air temperatures, consistent surface temperatures, draft-free spaces, and better humidity control. This will give a home or commercial property constant comfort and maximum energy efficiency.
