The CREST Passive Pavilion, Northern Ireland’s first Passive House, BREEAM Excellent and carbon neutral building, and an exemplar of sustainable construction. CREST provides industry R&D, demonstration and testing facilities for new renewable energy products and sustainable technologies. The facilities are available to businesses or individuals within Northern Ireland, the border counties of Ireland and Western Scotland who have ideas for new products or process developments but who do not have the physical and/or technical capacity to develop, test and commercialise them. The facilities include laboratory space, testing equipment, demonstration technologies and the assistance of technical staff to help bring ideas and concepts to the next stage of development.
