1/4OF THE TOTAL HEAT LOSS CAN BE
ATTRIBUTED TO SUSPENDED FLOORS
1. Opportunity – Heat loss from suspended timber floors

1. Opportunity – Heat loss from suspended timber floors
The heat loss from suspended timber ground floors includes not just conductive heat loss to the ground and surroundings, but also the infiltration of cold air through the void and floorboards, driving heat loss through the rest of the property.
1. DECC, Digest of UK Energy Statistics, 2012
2. I. A.Rock, I.R.Macmillan, The Victorian House manual. Care and repair for all popular house types, Somerset, Haynes Publishing, 2005.
The Air Changes per Hour (ACH) can be as high as 0.5 to 1 for a property with a suspended timber floor. This means that the air in a room is completely replaced every 1-2 hours, therefore the air in the room also has to be reheated every 1-2 hours or temperatures will quickly fall when the heating is turned off.

3. Impact – How we measure impact
Step 1: Determine the U-Value (W/m2.K)
of the floor via one of two methods:
• Measurement of the U-Value in situ
and internal temperatures by pre and
post install data logging (ISO 9869).
• Calculation of the U-Value based on
physical measurements of the void
and property (ISO 13370).

Step 2: Air tightness testing to measure
pre and post Air Permeability (m3/hr.m2).

3. Impact – How we measure impact
Step 3: Independent calculation using SAP of EPC rating pre and post install.
Step 4: Calculation of pre and post install EPC ratings for other energy efficiency measures for
comparison.
Step 5: Pre and post resident questionnaires to gauge qualitative feedback.

3. Impact – Feedback from the residents
“I am absolutely delighted. My flat has never been described as cosy before. It is warm, quieter and there are less cold draughts.”
“I have definitely noticed a difference. The property keeps the heat better, stays warm and is a lot less draughty now.”
“The work was done efficiently and at all times politely.”
“Much warmer – I now make more use of the ground floor, before the heating just couldn’t make it warm.”
“It has been great over this cold snap, it’s been much warmer and I’m spending less on heating.”
“I’m not using the heating as much as before as the flat holds the heat much better.”
“Friends no longer comment on my flat being freezing.”
“It does feel warmer in here, it did immediately.”
“No draughts up the floorboards, which is great.”
