Retrofit

When embarking on a renovation project, there is a lot to consider. Balancing aspirations, budget and the refurbishment needs of the property is not a simple task.

Our dedicated refurbishment offering allows you to clearly identify and prioritise different areas of work to and best understand the cost and carbon impacts of the choices you’ll make at each stage; allowing you to mitigate risk and make confident decisions.

Existing Property Heat Loss Measurements

During a site visit, our engineers will test the air leakage, and wall u-values, set up monitoring devices, and take meter readings to allow us to establish the properties heat transfer coefficient (HTC) and peak heat load (over a three-week period).

For this service to be effective external temperatures need to be c.10°C or lower.

Building Fabric Risk Assessment

Ahead of retrofit projects, it’s important to identify & plan to mitigate against the potential risks associated with the building’s fabric—walls, floors, roofs, windows, and doors—before implementing energy-efficient upgrades.

Our survey will identify the existing fabric build-ups for accurate heat loss modelling later on and provide a prioritised pre-retrofit recommendations report.

Moisture Management

Evaluating risks related to condensation, dampness, and mould that could affect both new and existing building elements.

Thermal Bridging

Identifying and addressing areas where heat transfer might bypass insulation, reducing overall efficiency and create an increased risk of mould and damp.

Ventilation

Ensuring that retrofitting measures do not adversely affect air quality and ventilation, which are crucial for occupant health and comfort.

Pre-Retrofit Maintenance Works

A prioritised list of maintenance work which would need to take place before thermal upgrades.

Heritage Risk Assessment

Thermal Imaging

A thermal imaging survey is a useful addition to highlight areas of air ingress, thermal bridging and risk of interstitial condensation and mould growth. It is also very useful to help understand if insulation has been installed correctly or if cavity wall insulation has failed.

This is most effective when a property is heated and the temperature outside is lower than c.10°C, we would only advise under these conditions.

Insulation Optimisation

Post Occupancy Heat Loss Measurements

This service is for new build properties or newly completed retrofits.

We know that there is often a shortfall between what is designed and what is achieved from a building fabric performance standpoint. Our comprehensive survey allows you to assess the as-built performance of the building fabric to best understand if the project goals have been met.

During a site visit our engineers will test air leakage, wall u-values, set up monitoring devices and take meter readings to allow us to establish the properties heat transfer coefficient (HTC) and peak heat load (over a three-week period).

For this service to be effective external temperatures need to be c.10°C or lower.
