Heat Ventilation
D & E Technical Services Ltd
When designing a project requiring ventilation, extraction or both there are several key factors that have to be considered to comply with the latest building regulations.
The stated fresh air requirement for general buildings is 10 litres/sec per person which meets Design Part F & Part L Building Regulations. We ensure our designs achieve the design criteria for that particular environment allowing fresh air to circulate around the workplace effectively whilst replacing stale and noxious air, providing a healthier working environment.
Our design engineers calculate the required air change rates, air volumes, fan duty, duct work and grille sizes to ensure acceptable air velocity and sound levels are achieved. This combined with systems offering excellent performance and energy efficiency.

- Fresh air ventilation
- Extraction of stale pollutants air
- Improves productivity in the workplace
- Significant saving in energy consumption
- Maintains a fresh healthy working environment
- Designed to work alongside air conditioning systems
Our designs primarily focus on providing energy efficient, effective, reliable systems designed to meet your exact requirements and budgets.
We can design and implement a bespoke ventilation/extract system at an affordable cost that can operate independently or in conjunction with existing or new air conditioning systems. We also install heat recovery ventilation (HRV) systems designed to reduce energy loss through buildings. | ![]() |
