This project examined a range of different retrofit options for the DHHS’s extensive range of public housing. The housing was divided into categories and recommendations were made on the most cost-effective options for each housing type. For example, some housing types gain the most value from draught-sealing, others from solar power systems, others from insulation. The project also made recommendations on how different retrofit measures complement each other, e.g. airconditioning gives the best results in terms of cost-effectiveness and resident comfort if it is paired with draught-sealing.
The project considered the various options from a cost-effectiveness and resident comfort point of view. The information AEF provided is now used by DHHS to inform decision-making on housing retrofits.
