The IHBA says this is not the sole challenge facing the sector.
Builders say there is a concerning lack of skilled labour in Ireland's construction sector.
It is particularly the case in the wet trades - bricklaying, plastering and stonelaying, has seen drops of between 30% and 44% in the number of new apprentices.
It comes as a member of the Climate Advisory Council warned the workforce isn't there to meet the demand for new homes and deep retrofits.
A new climate plan with details of a retrofit programme is expected to be published in the coming months.
