•Supply Technology

•Demand Reduction

•Matching Supply with Demand

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 speed and directionWind speed and direction

Prevailing wind direction SW

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

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

•Topography•Site offers many views•Most important would be view of Loch and Quinaig (nearest mountian range).

Site Selection CriteriaSite Selection Criteria

Site Selection CriteriaSite Selection Criteria

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 Selection CriteriaSite Selection Criteria

• Existing road conditions

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.

Solid WasteSolid Waste

• Council collects bins twice weekly

Recycling• Kerbside collection for paper/card• Local Availability of recycling banks• Possible other options from LA

Future Projections

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
