 Houses - Checklist of Items to be completed prior to our arrival on Site

 

                         

  1. Prior to attending site we will require a set of dimensioned floor plans and elevations to calculate floor, wall & roof areas.

 

  1. We will require the Design Air Leakage Rate or Air Permeability for the building. For commercial buildings this is generally 10 m3/hour/m2, but can be lower, if requested in the SAP rating report.

 

  1. We require TWO 240v Electric sockets within 25 metres of EACH of our testing equipment set up.

  

  1. Ensure that the completed building envelope is finished. All doors, windows, and cladding must be installed, or if items, such as glazing are missing, they should be sealed up to prevent air leakage. Please note that temporarily sealing items with tape should be limited to those items detailed in item 5.

 

  1. Seal with tape or cardboard any duct work and mechanical vents to the outside. Pay particular attention to the air conditioning system.

 

  1. Seal all ducts and penetrations where the main services enter the building. We have encountered many tests where a water pipe duct has been left unsealed underneath kitchen units. After services have been installed in the duct, seal the rest of the duct.

 

  1. Seal all SVP and waste pipe penetrations passing through external walls and ceilings. Make sure that the tops, sides & ends of all pipe boxing’s are sealed to prevent air leaking into the boxing and escaping through SVP/waste pipe penetrations. Bath panels should also be fully sealed.

 

  1. Ensure that all toilets and U bends in sinks have water in them.

 

  1. Ensure all external doors and windows are closed fully and make sure all trickle vents closed but NOT SEALED. Internal doors should be wedged open.

 

  1. All penetrations through floors & ceilings should be sealed.

 

  1. The boiler flue must be sealed where it penetrates walls or ceilings

 

  1.  In some houses storage cupboards have been built into the roof space. The doors when closed should seal the room from the roof space. Fit draught excluder if necessary to top, bottom & sides of door/frame

 

  1. Have a competent member of your staff available on the test day to modify and/or seal any further areas that we identify as requiring extra work.

 

  1. If the door/s chosen for the test have a larger opening larger than 1.200m x 2.100m high, you will need to modify the opening to suit our standard template.

(Please call us for advice should this be required.)

 

  1. Whilst we would prefer to have the building empty during the test duration, people can stay in the building whilst the test is in progress. They may not however enter or leave during the test period. (Approx 1 hour)

 

  1. We require a parking space for a transit van type vehicle within 10 metres of the test location on site.

 

  1. Testing cannot take place in high winds or if significant temperature differences persist, particularly for high buildings. You should inform us immediately if on the day of the test high winds in excess of 6 m/s are experienced, and a personnel door in a sheltered area cannot be utilised. If we arrive on site to carryout the test and have to abort the test due to windspeeds in excess of 6 m/s the full test fee will be payable.

 

  1. If we arrive on site and are delayed due to the site not being prepared adequately, or the items in this checklist not being completed prior to our arrival, we reserve the right to cancel the test. The full test fee will be payable.
