RETROFIT SERVICES 

What is Retrofit?

BSI PAS 2030 refers to the specific requirements for retrofitting properties, including the assessment of properties for retrofit. It also allows for the identification and evaluation of improvement options (energy efficiency measures or EEMs), which not only save money but also keep your property warmer during the winter months. The standard covers the design and specification of EEMs (whether individual measures or packages of multiple measures), as well as the monitoring and evaluation of retrofit projects, including External Wall Insulation, ventilation, and air source heat pumps.

PAS 2035 is the overarching document in the retrofit standards framework. Users of the TrustMark Government-endorsed quality scheme are required to comply with PAS 2035 when carrying out domestic retrofit work.

Those involved in domestic retrofit projects (including retrofit advisors, assessors, coordinators, designers, and evaluators) should have a working knowledge of building physics/building science appropriate to the nature and scale of the retrofit project. This includes an understanding of heat, moisture, and air movement through dwellings.

Occupants’ comfort, health, and safety depend on the proper control and management of heat, moisture, and air within their homes to maintain appropriate thermal and moisture equilibrium. The dynamic heat balance of a property (i.e., the way in which heat losses are balanced by heat inputs) is an important element of its energy efficiency, alongside moisture balance.

What Role Does EEH Solutions Play?

We are an accredited retrofit installer with the relevant PAS 2030/2035 competency. We have access to a wide range of professionals, including trade teams for our installations, covering domestic homes to low-rise apartments and flats.

Before each project, EEH Solutions carries out a thorough technical survey, including an on-site assessment to evaluate the property, structural evaluation, and resource planning. This data is crucial for a smooth transition from start to finish, as well as for completing the necessary retrofit assessment.

We also perform retrofit coordination in-house, planning and scheduling the development of projects in compliance with Health and Safety, Legal Regulations, Environmental Guidelines, and accessibility requirements. Communication remains consistent throughout the project, and we conduct evaluations at the end of each project to ensure complete satisfaction.

EEH Solutions also manages projects internally, including on-site supervision with relevant Health and Safety management, resource management, and Quality Control, all of which are paramount to the safety of our employees and clients.

Surveys and Assessments

Before any retrofit work begins, a comprehensive survey and assessment process is conducted to ensure the most suitable measures are implemented. This includes:

  • Retrofit Assessment: Evaluating the property’s existing condition, identifying areas for improvement, and determining the most effective energy efficiency measures.

  • Structural Evaluation: Ensuring the building can accommodate retrofit installations without compromising its integrity.

  • Technical Surveys: Gathering essential data for retrofit planning, including insulation, ventilation, heating systems, and energy consumption.

 

PAS Roles

EEH Solutions ensures full compliance with PAS 2030 and PAS 2035 standards through designated roles within the retrofit framework:

  • Retrofit Assessor: Conducts property assessments and provides detailed reports on necessary energy efficiency improvements.

  • Retrofit Coordinator: Oversees the entire retrofit project, ensuring compliance with PAS standards, quality assurance, and efficient project execution.

  • Retrofit Installer: Implements energy efficiency measures in accordance with PAS 2030 requirements.

  • Retrofit Evaluator: Reviews completed projects, assessing performance improvements and ensuring customer satisfaction.

 

Testing and Commissioning

Additional Ventilation Requirements

The ventilation improvements carried out under PAS 2030 and PAS 2035 ensure properties are well-ventilated, maintaining fresh air circulation and preventing moisture-related damage to walls. Proper ventilation helps retain warmth within the home, ultimately improving indoor air quality and making homes more comfortable and energy-efficient.

Air Pressure Testing Requirements

Air pressure testing under PAS 2030 and PAS 2035 helps identify uncontrolled air leakage through gaps and cracks in the building. This assessment determines how much energy is lost due to air infiltration and highlights areas where further measures or improvements may be required to enhance energy efficiency and overall comfort.
