Retrofitting for the Future Homes Standard 

Sustainable living is crucial for the health of our planet and the well-being of future generations. The UK government’s commitment to achieving net zero greenhouse gas emissions by 2050 under the Climate Change Act 2008 set the stage for a new set of sustainable building regulations, the Future Homes Standard, which underpins a national effort to combat climate change. 

What is the Future Homes Standard?

The Future Homes Standard (FHS) is a set of regulations that will come into effect in 2025 in England to ensure that new homes are more energy-efficient and produce lower carbon emissions. 

The FHS aims to decarbonise new homes by focusing on improving heating, hot water systems, and reducing heat waste. It will require new homes to be future-proofed with low carbon heating and world-leading levels of energy efficiency, aiming to reduce carbon emissions by 75-80% compared to current standards. 

Crucially, the FHS will also apply to existing homes and certain home improvements, with higher standards being required for thermal upgrades or extensions. 

However, there is a significant retrofit skills gap in the UK. And the qualifications required to assess, design, and install improvements that lead to enhanced energy efficiency are vital to all aspects of the UK 2050 climate commitment. 

In support of these initiatives, we’ve developed our renewable energy programs, including the new Retrofit program, to help educate a skilled workforce capable of transforming existing buildings into energy-efficient, sustainable structures. 


Understanding Retrofitting 

Retrofitting refers to the process of updating existing buildings to improve their energy efficiency and functionality. This is a key strategy in reducing carbon emissions, as a significant portion of the UK’s carbon footprint comes from the built environment. 


Benefits of Retrofitting 

Retrofitting buildings not only contributes to the reduction of carbon emissions but also enhances the comfort and health of occupants, reduces energy costs, and supports the UK’s transition to a sustainable, low-carbon economy. 

So, what can you do to help? What techniques are involved? And where can you start learning about retrofitting? 


Introduction to Retrofitting Techniques 

Various techniques are essential for upgrading buildings. Each of these techniques is in line with the UK Net Zero Carbon Buildings Standard, which provides a methodology for proving that built assets are net zero carbon. 


Retrofitting Techniques for Energy Efficiency 

Energy efficiency is a key aspect of retrofitting, contributing to reduced energy consumption and lower carbon emissions. Techniques include: 

  • Insulation: Adding or improving insulation in walls, roofs, and floors to reduce heat loss. 
  • Energy-Efficient Windows: Installing double-glazed or triple-glazed windows to improve thermal performance. 
  • LED Lighting: Replacing incandescent bulbs with LED lighting to reduce energy use. 
  • Solar Panels: Incorporating solar photovoltaic panels to generate renewable energy. 
  • High-Efficiency HVAC Systems: Upgrading to more efficient heating, ventilation, and air conditioning systems to reduce energy consumption. 
  • Smart Thermostats: Using programmable thermostats for better control over heating and cooling, optimising energy use. 


Retrofitting Techniques for Water Conservation 

Water conservation is a critical aspect of sustainable living. Retrofitting techniques such as installing low-flow fixtures and rainwater harvesting systems can significantly reduce water usage in buildings. 

  • Low-flow Faucets and Showerheads: Installing devices that reduce water flow without compromising functionality. 
  • Toilet Retrofits: Using toilet inserts or dual-flush mechanisms to minimise water per flush. 
  • Leak Detection and Repair: Identifying and fixing leaks to prevent water wastage. 
  • Rainwater Harvesting Systems: Collecting and using rainwater for non-potable purposes like irrigation and flushing toilets. 
  • Water-Efficient Landscaping: Employing drought-resistant plants and efficient irrigation systems to reduce outdoor water use. 


Retrofitting Techniques for Waste Management 

Effective waste management strategies, including recycling and composting, can be integrated into retrofit projects to minimise the environmental impact of buildings. 

  • Recycling and Composting Facilities: Implementing systems for separating and recycling waste, as well as composting organic materials. 
  • Construction Material Recycling: Reusing and recycling materials during the retrofitting process to reduce waste. 
  • Waste Audits: Conducting audits to identify major sources of waste and opportunities for reduction. 
  • Sustainable Materials: Choosing materials with lower environmental impacts, including recycled content and sustainably sourced products. 


Retrofitting Techniques for Indoor Air Quality 

Improving indoor air quality is essential for occupant health. Retrofitting can address this through better ventilation systems, the use of non-toxic building materials, and the incorporation of air-purifying plants. 

  • Enhanced Ventilation Systems: Installing or upgrading ventilation systems to ensure adequate fresh air supply. 
  • Low-VOC Materials: Using materials and finishes that emit low levels of volatile organic compounds. 
  • Air Purification: Incorporating air purifiers or plants that can help remove pollutants from indoor air. 
  • Regular Maintenance: Ensuring HVAC systems and filters are regularly cleaned and maintained to prevent indoor air pollution. 


Why Retrofitting is Important for Sustainable Living 

Retrofitting aligns vitally with the national retrofit strategy and contributes to the achievement of zero-carbon homes. It’s just one of the many ways that we’re helping provide the educational resources to support a more sustainable future. 

If you’re interested in learning more about best practices for retrofitting, the LETI Retrofit Guide provides comprehensive guidance on retrofitting homes to support the UK’s Net Zero targets. 

If you’re ready to get involved, Metaverse Learning’s Retrofit program provides the necessary training and skills development to close the skills gap and accelerate the development of sustainable living in the UK.
