Proving a point…
Recently, Rob conducted a heat-loss calculation on his own three-bed Victorian terrace which showed a 4.76KW of heat loss through the building fabric.
Measure to manage
Rob told us “I was shocked at the result but had faith in the science and set about hydronically balancing and adjusting the heat curve and output on my boiler to match the calculated requirement. The result of these small changes has shown a vast reduction in gas usage and yet my property maintains a very comfortable 21oC.”
Rob points out “We have got it so wrong for so long. We could do so much more and my boiler still cycles somewhat because one simply cannot turn it down far enough.”
Rob wants to see government update the building regulations to incorporate accredited heat-loss calculations into the planning process. This will work alongside the current, theoretical-only SAP and ErP reports. The final icing on the cake for Rob would be building performance testing under full heat load with calibrated thermography imaging.
Rob concludes “…Is it really too much to expect that minimum building regulations are applied, enforced, calculations are done and proper performance testing is correctly administered? No, I didn’t think so either!”
