Project AimsProject Aims
•Low energy, sustainable building
•Develop energy systems
•Create environment that is not compromised
Initial Design Proposal
OccupantsOccupants
• Outdoor community• Relaxation• Sustainable• Low visual impact• Local Materials• Aesthetically pleasing
Initial ResearchInitial Research
•Site selection– Access – Topography– Geology– Visual impact
•Water supply
•Waste management
•Site Analysis–Climate–Local resources

Solar intensitySolar intensity
Direct solar intensity• Unpredictable• Peaks at 870W/m²K
Diffuse solar intensity• Sinusoidal• Average around
100W/m²K
Passive Solar DesignPassive Solar Design
• Passive Solar Heating in winter
(sunspaces, thermal mass)
• Passive Solar Cooling in summer
(thermal mass, night ventilation)
Wind Driven VentilationWind Driven Ventilation
Savings• Energy consumption
up to £6000• CO2 emissions upto
100 tonnes
Reduce requirement for mechanical ventilation
Cross ventilation and stack effect also a possibility

Local ResourcesLocal ResourcesTimber
Utilisation from nearby forests
NHFT promote• Woodchip for cattle corals• Woodchip as fuel source for swimming
pools• Development of log buildings and training
in log building
Local ResourcesLocal Resources
• Local quarries • High quality stone• Used internally and externally
Stone
Site Selection CriteriaSite Selection Criteria
•Topography•Site offers many views•Most important would be view of Loch and Quinaig (nearest mountian range).
Site Selection CriteriaSite Selection Criteria
• Geology• Surrounding metamorphic and igneous
rocks • Alluvial and glacial deposits at Loch side• Alluvial and glacial deposits cheaper for
excavation• Test on Californian bearing ratio will be
required (on granular and unbound sub soils)
Site Selection CriteriaSite Selection Criteria
• Access• Fish farm there at present so roads to
site C will be able to handle lorries (local information from fish farm and hotel)• Virgin roads built with passing places,
drainage and fencing can cost £250 thousand
(fife council)• Site C also has advantage of Jetty
Site SelectionSite Selection
• Visual Impact
• Site C- In amongst other buildings so visual impact will be reduced
• A and B are virgin sites so will stand out
• Especially B which is on an open embankment
Site Selection CriteriaSite Selection Criteria
• Water access• Mains saturated in highlands(highland free press)• Site B is closest to road so would be
cheapest to connect to mains.• All sites are close to stream, • Site C has largest stream and deepest V
valley. More likely for reservoir.
Site SelectionSite Selection
Conclusion• We therefore choose site C as it offers
the greatest flexibility and opportunities for further design.

Biodigester Good Good Environmentally friendly
Stabilisation pond
Fair Good No treatment requiredLarge area needed
Solid WasteSolid Waste
• Council collects bins twice weekly
Recycling• Kerbside collection for paper/card• Local Availability of recycling banks• Possible other options from LA
Initial ConclusionsInitial Conclusions
• Site C– Better access – “easier” excavation– Less visual impact– greatest water source
Targets for FutureTargets for Future
•Presentation 2– Initial building design– Ventilation and Heat Recovery– HVAC systems– Demand profile– Demand reduction
•Presentation 3– Continuation of building design– Lighting and Electrical Supplies– Control strategies– Power supply
Targets for FutureTargets for Future
•Presentation 4– Continuation of building design– Supply/Demand matching techniques
•Presentation 5– Final Proposal– Prime example of sustainable design
