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

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
