With over 1,450km of rocky shoreline, Ireland's coast is surrounded by hundreds of species of seaweed. For centuries, this seaweed has been harvested by coastal communities and used by farmers for fertilising their fields, as a home remedy for bronchitis and chronic coughs, and is even said to be one of the two foods that St Colmcille survived on.

Healthier houses are an important step to help mitigate climate change, with Irish homes responsible for one quarter of overall energy use and 10% of greenhouse gas emissions. As well as reducing a home's emissions, modern ventilation and insulation systems are key to improving air quality in houses, benefiting the health of the buildings themselves and the health of the people who live and, now more frequently than ever, work in them.
