Ventilation Solutions: Enhancing Indoor Air Quality for Sustainable Properties

At TF Energy we provide ventilation solutions for both domestic and commercial properties.


From simple extract systems to advanced mechanical ventilation with heat recovery (MVHR), we ensure every installation is designed to meet PAS 2035, Building Regulations, and occupant needs. 

Good ventilation is essential for healthy, comfortable, and energy-efficient buildings. As insulation levels improve and properties become more airtight, effective ventilation ensures that fresh air circulates, moisture is controlled, and indoor air quality is protected.

Domestic Ventilation:

As UK homes become more airtight through insulation and energy upgrades, ventilation is no longer optional, it is a regulatory requirement under PAS 2030 and PAS 2035. Proper ventilation strategies ensure that stale, warm, humid air is extracted and replaced with clean, fresh air, protecting residents’ health, the building fabric, and the long-term performance of retrofit measures. 

 

At TF Energy we design and install full domestic ventilation strategies for residential properties, ensuring compliance, comfort, and efficiency. 

Why Domestic Ventilation Matters:

  • Prevents condensation, damp, and mould that damage properties and impact health. 
  • Protects insulation and retrofit upgrades from premature failure. 
  • Ensures indoor air quality meets PAS 2030 requirements. 
  • Balances energy efficiency with comfort, avoiding overheating or stale air. 

Whole-House Approach:

PAS 2030 requires that ventilation is considered as part of every retrofit project. At TF Energy we take a whole-house approach, combining extraction, background ventilation, and roof space ventilation to ensure properties remain healthy, compliant, and efficient. 


We install low-voltage, continuous mechanical extract ventilation units (dMEVs) in all wet rooms such as kitchens, bathrooms, and utility spaces. These continuously remove stale, warm, moisture-laden air at source. 

 

Key outcomes: 

  • Constant extraction in high-risk areas. 
  • Reduced condensation and damp. 
  • Quiet, energy-efficient operation. 


Background Ventilation:

Background ventilation is essential to ensure a constant flow of fresh air through the property. This can be achieved through: 

  • Wall vents 
  • Trickle vents in windows 
  • Window slot vents 
  • Door undercuts (minimum 10mm) to enable whole-house circulation 

 

Key outcomes: 

  • Continuous airflow without resident intervention. 
  • Whole-house air circulation to support dMEVs. 
  • Compliance with retrofit ventilation requirements.


Loft & Roof Ventilation:

Roof spaces also require adequate airflow to prevent condensation build-up, which can lead to damp and structural issues. 

 

We provide: 

  • Roof tile vents 
  • Felt lap vents 
  • Soffit vents 

 

Key outcomes: 

  • Dry, healthy roof spaces. 
  • Protection of insulation and timber structures. 
  • Long-term building fabric performance. 


Positive Input Ventilation (PIV):

PIV systems bring in filtered, fresh air from outside and gently circulate it through the home, pushing out stale air and maintaining healthy airflow. 

 

Key outcomes:

  • Constant supply of fresh, clean air. 
  • Reduces allergens, pollutants, and humidity. 
  • Affordable, whole-house solutioN.


Loft & Roof Ventilation:

MVHR systems continuously extract stale, warm air and replace it with fresh, filtered air — while recovering the heat energy from the outgoing air to reduce energy waste. 

 

Key outcomes:

  • Balanced ventilation for the entire property. 
  • Fresh air supply with minimal heat loss. 
  • Ideal for airtight or highly insulated homes. 


Positive Input Ventilation (PIV):

PIV systems bring in filtered, fresh air from outside and gently circulate it through the home, pushing out stale air and maintaining healthy airflow. 

 

Key outcomes:

  • Constant supply of fresh, clean air. 
  • Reduces allergens, pollutants, and humidity. 
  • Affordable, whole-house solutioN.
