Assistance and Advice


Our projects division has a wealth of experience designing low energy, cost effective ventilation projects nationwide for Architects, M&E Consultants and Contractors.

We offer a design and consultancy service to our clients including assistance in selecting products and putting forward proposals for ventilation systems based on industry specifications, guidelines and criteria.

Our design engineers can provide bespoke product design using the latest 3D and 2D design applications, provide analysis and feasibility studies and carry out simulations to ensure the best possible and efficient solution is selected for your project.

All our projects comply to the CIBSE Guidelines for ventilation and indoor air quality. We adhere to designing the best solution with thermal comfort, air quality and energy efficiency in mind.

Our in house thermal modelling and CFD software allows our design team to simulate overheating and ventilation in all building environments.

Thermal Modelling

GDL has in-house thermal and air flow modelling software to simulate overheating and ventilation for the construction industry. Our designers and engineers can use 3D modelling techniques to model buildings for simulating solar heat gains using EDSL TAS.

Thermal modelling is an integral part of designing systems to ensure overheating and over cooling of buildings for the future is kept to a minimum.
