Extension & Refurbishment of Victorian Townhouse using Passivhaus methodology and CarbonLite guidance. Certified to the Passivhaus Institute's new EnerPHit (refurbishment) Standard. CAUTION wrt forecast vs measured performance data: first 18 months after construction work can involve a lot of 'drying out', this can potentially temporarily double space heat requirements. Forecasts are based on a 'typical year' rather than 'actual' year measured. Measured data here is from 2005/06 (before) and 2009/10 (after). Measured room temperatures show an average of 21 degrees centigrade during the heating season. Other factors may also influence results. Following certification some information is in the process of being updated. Please note the final air leakage as certified under EnerPHit was an N50 of 1.0 ACH.
