Because the labour is semiskilled, it helps to keep build costs down too. There was also a wider emphasis on using local suppliers and labour on the job and, according to Beattie Passive estimates, for every £1 spent on the Bradwell project, £2.84 was circulated back into the local economy. Beattie Passive has published a breakdown of the costs for two of the certified passive houses at Bradwell on its website: www.beattiepassiveprojects.com.
