ChangeX is an annual exhibition of new graduate designs and ideas that address issues of sustainability, environmental change and responsibility, social equity and community, often directly challenging conventional expectations. The twenty or so student works range across the design spectrum from industrial design, graphics, architecture, textiles, planning, through to landscape design and more. This years exhibition will feature 2D / 3D works, audio/visual content and even high fashion model. We noted last years event here. Organised by the volunteer run Society for Responsible Design (SRD), one of the world’s oldest eco-design organisations, (founded in 1989), ChangeX is about showcasing the future thinking of today’s university graduates. In past years significant interest has been expressed in commercialising some the student’s work. The breadth of their passion and imagination will be on display at GREX 07 (the 2nd Australian International Green Build & Renewable Energy Exhibition and Conference) which starts Friday 1 June and runs through to Sunday 3 June, at the refurbished locomotive workshops that are now known as Australian Technology Park in Redfern, Sydney. Not only will the SRD’s ChangeX be in attendance, but also other events such as the G-Film World Environment Day Short Film Festival, the House of the Future Competition, the GREX Innovation Awards and a Green Living Zone. Additionally there will be 30 keynote seminars on all manner of green issues. Entry is free on the Friday with ID, the weekend days are $15 AUD. ::ChangeX '07 and ::GREX.Disclosure: This writer has been a committee member of the SRD for the past dozen or so years.
