Air Tightness Testing for Public Sector Buildings

Public sector buildings have a lot to deal with.

Schools, hospitals, council buildings, and government sites all need to stay safe, comfortable, efficient, and compliant — often while being used every day.

That means energy performance can’t just look good on paper. It needs to work properly in real life.

We help public sector teams understand how their buildings are performing, where energy is being lost, and what needs improving to support compliance, comfort, and long-term running costs.

Who This Is For

This service is typically used by:

  • Schools and academy trusts
  • NHS estates and healthcare buildings
  • Local authorities and councils
  • Government buildings
  • Facilities and estates managers
  • Public sector contractors

If you’re responsible for keeping public buildings compliant, efficient, and comfortable, this is where clear testing makes a real difference.

Why Public Sector Buildings Need Clear Performance Data

Public sector buildings are often complex.

You may be dealing with older buildings, mixed-use spaces, phased upgrades, limited budgets, and high occupancy.

Common issues we see include:

  • Heat loss through ageing building fabric
  • Poor airflow in busy spaces
  • Ventilation that doesn’t perform as intended
  • Inconsistent temperatures across different rooms or areas
  • Higher-than-expected energy use

These issues can lead to:

  • Higher operational costs
  • Reduced comfort for occupants
  • Damp, condensation, or poor air quality
  • Difficulty proving compliance
  • Pressure on maintenance budgets

Testing gives you the evidence needed to make better decisions.

If you’ve got a project coming up and want to avoid delays at the final stage, get in touch and we’ll help you get it right first time.

Air Tightness Testing For Public Sector Buildings

Air tightness testing measures how much uncontrolled air is leaking through the building.

In public sector buildings, this can affect:

  • Energy performance
  • Heating and cooling costs
  • Occupant comfort
  • Compliance with building standards

Our testing helps you:

  • Identify where energy is being lost
  • Support energy efficiency improvements
  • Improve comfort across the building
  • Meet air tightness and energy compliance requirements
  • Plan works based on real evidence

We explain the results clearly, so your team understands what’s happening and what needs to happen next.

What Happens During a Test?

We use specialist testing equipment to measure how air is moving through the building.

The process usually involves:

  • Setting up calibrated testing equipment
  • Pressurising and depressurising the building
  • Measuring air leakage rates
  • Identifying likely areas of air loss
  • This gives you a clear picture of how the building is performing in real conditions.

For public sector estates, that evidence can help prioritise improvement works and avoid wasting budget on the wrong fixes.

Energy Efficiency And Sustainability Support

Public sector organisations are under increasing pressure to reduce energy use and improve sustainability.

We support this by helping you understand where buildings are underperforming and which improvements are likely to have the biggest impact.

This can help you:

  • Reduce avoidable energy waste
  • Lower long-term operational costs
  • Support sustainability targets
  • Improve comfort for staff, patients, pupils, visitors, or building users
  • Make evidence-led decisions across your estate

Ventilation Compliance And Indoor Air Quality

Ventilation matters in public buildings — especially in busy spaces like classrooms, clinics, waiting rooms, offices, and shared facilities.

If ventilation is not working properly, it can lead to:

  • Poor indoor air quality
  • Condensation and moisture issues
  • Discomfort for occupants
  • Inefficient heating and cooling

We assess ventilation performance to help make sure airflow is working properly, supporting both compliance and a healthier indoor environment.

Built Around Public Sector Sites

Public sector buildings are rarely simple to access or test.

You may need to work around:

  • School hours and term dates
  • Patient care and clinical spaces
  • Staff working areas
  • Public access
  • Security requirements

We keep the process practical, with:

  • Flexible scheduling
  • Clear communication with site teams
  • Straightforward reporting
  • Practical advice your team can act on

Our aim is to help you improve building performance without creating unnecessary disruption.
