This course will revolutionise the knowledge on smoke control for all sectors of the industry. We have developed a highly innovative method of determining the ventilation requirements of virtually any building with an atrium from start to finish. Application of this method has been designed to make sure you consider all areas required to ensure the smoke control system is compliant and will certify that the design objectives are met.

Smoke Control Made Simple – Version 2

Smoke control made simple version 2 is a comprehensive course covering all the principles of smoke control following the eleven step guide and incorporates all the areas covered in version 1. However, this course goes into detail on all the calculations involved in determining the requirements of a smoke control system.  The course is accompanied by a workbook incorporating 69 pages of exercises. This course will give you an invaluable insight into the principles of smoke management. On completion of this course you will have the ability and confidence to carry out calculations that previously had to be carried out by qualified Fire Engineers. It will enable enforcing authorities, including building control bodies and fire authorities, to be able to check schemes prior to confirming code compliance. This should allow the field of smoke management to advance due to a greater understanding of the subject.

On completion of this course you will be able to complete the following exercises

Exercise 1

A twin span sprinklered building is used for the storage of miscellaneous goods up to a height of 7m. The smoke exhaust system is for property protection only. The assumed heat release rate for the goods stored is 625 kWm-2.

Exercise 9

An office building has a 32m high atrium. The atrium is entirely enclosed by fire resisting glazing and construction but at ground floor and first floor there are a small number of openings into the atrium from adjacent rooms. The building is sprinklered with the exception of the atrium. There is no fire loading is permitted within the atrium base. The design fire is based on the figures for offices given in table 3.3 on page 18 of BR368. There will be a very small ambient temperature gradient between the top and the bottom of the atrium equal to 0.3Km-1.

 
 
Exercise 9

Exercise 9

The openings into the atrium are as follows:

a) Two at ground floor, both 2.6m high and 9m wide. These come from separate rooms with fire resisting walls separating them

b) One at first floor level 3.2m high and 6m wide.

c) c) One at second floor level 2.6m high and 5m wide. The top of this opening is 9.0m above the ground floor in the atrium.

Any spill plume would be adhered. There are no balconies outside the openings, the smoke will simply leave an opening and travel straight up the wall above it. There is a downstand at the openings. There is to be mechanical ventilation at the top of the atrium (32m above ground). The fans are rated at 11m3.sec with a throat diameter of 0.9m

The atrium is not large enough to require more than a single reservoir (1450m2) so replacement air for the SHEVS will be supplied by automatic opening doors and vents at ground and first floor level with a total geometric area of 8.2m2.

  1. Where should the base of the smoke layer be allowed to descend to ?
  2. Determine the ventilation requirements of the atrium
  3. Does the glass require to be insulating?

Exercise 12

A plan has been submitted to convert two adjacent shop units into a single shop unit. The width of the proposed shop front will be 14m wide and 2.2m high. The shop is fitted with fast response sprinklers

Exercise 12

The units are on the ground floor and the mall has two storeys. There are balconies above the ground floor shop fronts as shown in this diagram which represents a section through the shop unit and mall outside it. The appropriate value for the coefficient of entrainment within the shop is 0.21. The down stand at the shop front is 0.5m deep. Assume the ambient temperature to be 288K or 15oC. Because the new large shop unit would spill smoke into two separate reservoirs, the designer proposes to create a small reservoir outside the shop unit to contain the smoke and to extract it mechanically from there.

The small reservoir will be 14m wide and 5.6m from the shop front downstand to the containment screen at the edge of the underside of the balcony. They have proposed to have 4 ventilators rated at 10m3.sec with a throat diameter of 0.9. The inlet air is provided by doors and automatic opening vents with an area of 11m2

Exercise 13

A shopping mall is fitted throughout with standard response sprinklers. There is a proposal to convert two adjacent shop units into a single shop unit. The width of the proposed shop front will be 12.2m and it will be 2.4m high.

Exercise 13

The units are on the ground floor and the mall has two storeys. There are balconies above the ground floor shop fronts as shown in this diagram which represents a section through the shop unit and mall outside it

The appropriate value for the coefficient of entrainment within the shop is 0.21. The down stand at the shop front is 0.5m deep. Assume the ambient temperature to be 288K or 15C.Because the new large shop unit would spill smoke into two separate reservoirs, the designer proposes to remove the down stand and use mechanical slot extraction at the front of the shop to stop any smoke from leaving the shop into the mall.

They have proposed a system which will extract 45m3.second

As a building control inspector can you check that the system will be adequate?

Exercise 14

A plan has been submitted to convert two adjacent shop units into a single shop unit. The width of the proposed shop front will be 11.5m wide and 2.4m high. The shop is fitted with standard response sprinklers

Exercise 14

The units are on the ground floor and the mall has two storeys. There are balconies above the ground floor shop fronts as shown in this diagram which represents a section through the shop unit and mall outside it. Because the new large shop unit would spill smoke into two separate reservoirs, the designer proposes to create a small reservoir outside the shop unit to contain the smoke and to extract it mechanically from there. The small reservoir will be 11.5m wide and 4.8m from the shop front downstand to the containment screen at the edge of the underside of the balcony
