Stage C Landscape Plan • REALL will build all major low carbon construction types to future targets now • All types will be subject to rigorous Energy, Occupant Satisfaction and IAQ POE •REALL will become an open source reference trial for use by Scottish Industry and Government •REALL will trial domestic Soft Landings procurement process •REALL offers industry the chance for integrated product testing and a high profile route to market REALL is Heriot Watt research contribution to Scottish Low Carbon Economy 17

Conclusion Despite nearly 50 years we do not consistently evaluate and fine tune in-use performance of our buildings. This results in a 2 to 5 increase in energy use We will not achieve Carbon Emission Targets We are adding complexity and cost to our buildings One Planet Living, Soft Landings, REALL closes this loop: Lessons learnt fed back into new and refurbished projects Design out complexity and reality check against real examples Graduated handover and focus on performance outcomes 18
