Car Park Ventilation: How much attenuation should a design include?

Posted by Conor Logan on 31/05/16 12:00

As a designer working on a car park project, there are important considerations you will need to make about ventilation to ensure good air quality. Approved Document F (ADF) stipulates that sufficient ventilation must be provided to enclosed car parks to avoid an excessive build up of carbon monoxide (CO).

When is smoke control needed in a car park?

Posted by Conor Logan on 24/05/16 12:00

Let me make it clear. I’m talking here about systems providing smoke control, not just smoke clearance as recommended in Building Regulations. These systems are much more complex and costly than compliant smoke clearance systems, so why would anyone choose to use them?

EcoDesign: will new regulations prevent jet fans from being used in car park ventilation schemes altogether?

Posted by Conor Logan on 15/09/15 11:30

The EU EcoDesign Energy Efficiency Regulation for Fans 327/2011, which sets EcoDesign requirements for fans, is going through its final stages of preparation. It has raised an important issue that impacts on car park ventilation schemes.

How to make car park ventilation schemes more energy-efficient

Posted by Conor Logan on 09/06/15 11:30

The Building Regulations do not advocate energy efficiency in car parks

The regulations applying to ventilation of car parks (at least in England and Wales) do not specifically advocate the conservation of energy, but surely they should do. It does not make sense that while buildings are subject to energy efficiency and low carbon emission targets driven by the Approved Document L of the Building Regulations, car park ventilation has no such requirement.

Moreover, an emphasis on lowest initial cost can mean that there is no consideration of the huge potential costs of running a ventilation system over the lifetime of a car park, and the CO2 emissions associated with this.

Can car park ventilation schemes be more energy efficient? Yes – and they should be!

Posted by Conor Logan on 07/10/14 11:30

Why is energy efficiency not regulated in car parks?

The regulations applying to car parks do not specifically advocate the conservation of energy but surely they should do. It does not make sense that buildings are subject to energy efficiency and low carbon emission targets driven by regulations such as Approved Document L (ADL), while car parks have no such requirement.

Inverter control for car park ventilation: Good or bad idea?

Posted by Paul Compton on 03/06/14 11:30

The debate: what is it all about?

Over the last few years there has been a lot of discussion about use of inverter control for smoke extract fans. This has centred on concerns that the changing characteristics of the fan motor as it heats up may cause inverter failure. Inverter manufacturers do offer models with an “emergency mode”, where the majority of protections are disabled with the intention of allowing the motor to run to destruction.

Car park ventilation: getting ‘free areas’ right in your design with the Colt webinar

Posted by Paul Compton on 20/08/13 11:17

Getting the design of car park ventilation systems right is essential car park screeningto the safety of a car park, as they must provide both day to day ventilation for the people using it and protection against fire, as required by Building Regulations. However, it’s not as straightforward as you might think.

Simple guidance on "free areas"...

Guidance on the ventilation requirements for car parks to meet the Building Regulations’ requirements is available in Approved Document B (ADB) and Approved Document F (ADF) for England, and their equivalents in Wales, Scotland and Northern Ireland.
