Our service

Our Pre-Construction Technical Design Reviews covering Air Tightness and Ventilation provide you with a comprehensive evaluation of your design and plans for your project. Ecotest will review your plans and any specifications in detail to identify potential risks and if necessary we will make recommendations for improvements. Our goal is to save you time and money throughout the build supporting you to achieve the required standards or air tightness and ventilation.

Contact us about your project


Ecotest want to support your project to achieve positive outcomes when it comes to Air Tightness and Ventilation. There’s a well known slogan in the energy efficiency sector of the construction industry that states, ‘build it tight, ventilate it right’.

We’ll review your design and plans


The design and plans are reviewed in detail to ensure that they are complete and accurate.

We’ll identify any details/risks to Air Tightness and Ventilation


Ecotest will identify any details that could provide risks to air tightness or the ventilation system, which may affect final building performance (energy efficiency and indoor air quality) sign off and the comfort of its occupants.

Analysis and Recommendations

Ecotest analyses the identified issues and makes recommendations for improvements, including design changes, alternative materials or systems, potential cost savings and risk reduction strategies.

A comprehensive report tailored to you

Final Report

Ecotest will provide a final report which summarises our findings and recommendations. The report will support you with the next steps towards implementation in your project. We can also continue to support you by working with designated site representatives, to ensure the delivery of our recommendations thought the project’s lifecycle.

What are the benefits of Pre-Construction Technical Design Reviews

The purpose of a Pre-Construction Technical Design Review is to identify and address potential risks early in the project, such as but not limited to:

  • incorrect ventilation specification and sizing, poor ducting design, inefficient layout and installation issues
  • air leakages that are difficult to access and rectify

We reduce the risk of costly remedial work later on in the project and ensure that the project meets the design intent, budget, schedule and requirements for compliance.

The benefits of reviewing drawings in advance of construction for air tightness and ventilation are as follows:

1. Compliance with Building Regulations

Reviewing the drawings in advance of construction can help to ensure that the building meets the requirements of the Building Regulations, reducing the risk to sign off with the build control body.

2. Cost Savings

Identifying and addressing potential issues with air tightness and ventilation design before construction begins, can help to reduce the risk of costly remedial work and the ongoing operational costs of the building for its intended occupants/owners.

3. Improved Air Tightness

A review of the building details, materials, and air tightness methods/products can help identify any potential sources of air leakage. These can then be addressed before construction begins and awareness and responsibility can be given to the on site construction team. This can improve the overall air tightness of the building, reducing energy consumption and improving indoor air quality.

4. Optimal Ventilation Design

The review of the ventilation design and specification of equipment can help ensure that the system is designed to meet the required building ventilation rates. This can help to ensure compliance to the Building Regulations, the design intent is achieved, improve indoor air quality, reduce the risk of indoor air pollution and reduce the risk of noise pollution.

5. Better Building Performance

Reviewing the air tightness and ventilation design in advance of construction can help to ensure that the building performs optimally, reducing energy consumption, improving indoor air quality and indoor comfort for its occupants and ultimately contributing to a more sustainable environment.
