Sustainable Hotel Design Presentation 1 Site and Resource Analysis Group 5
Semester 1 • Supply Technology • Demand Reduction • Matching Supply with Demand
Project Aims Initial Design Proposal • Low energy, sustainable building • Develop energy systems • Create environment that is not compromised
Occupants • Outdoor community • Relaxation • Sustainable • Low visual impact • Local Materials • Aesthetically pleasing
Initial Research • Site selection – Access – Topography – Geology – Visual impact • Water supply • Waste management • Site Analysis –Climate –Local resources
Climate and Local Resources
Maximum and Minimum Temperatures Summer Max 25. 7 °C Min 2. 5 °C Mean 13. 6 °C Winter Max 11. 4 °C Min -3. 9 °C Mean 5. 1 °C Transitional Max 19. 8°C Min -2. 5 °C Mean 9. 2 °C
Solar intensity Direct solar intensity • Unpredictable • Peaks at 870 W/m²K Diffuse solar intensity • Sinusoidal • Average around 100 W/m²K
Passive Solar Design • Passive Solar Heating in winter (sunspaces, thermal mass) • Passive Solar Cooling in summer (thermal mass, night ventilation)
Wind speed and direction Prevailing wind direction SW
Wind Driven Ventilation Reduce requirement for mechanical ventilation Savings • Energy consumption up to £ 6000 • CO 2 emissions upto 100 tonnes Cross ventilation and stack effect also a possibility
Rainfall Annual rainfall • 2277. 8 mm Collection: roof, pipes, tank pumps. Use: dishwasher, laundry, toilets, showers, etc
Local Resources Timber 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 Resources Stone • Local quarries • High quality stone • Used internally and externally
Site Selection Criteria
Site Selection Criteria • Topography • Site offers many views • Most important would be view of Loch and Quinaig (nearest mountian range).
Site Selection Criteria C B A
Site Selection Criteria
Site 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 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 Criteria • Existing road conditions
Site 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 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 Selection Conclusion • We therefore choose site C as it offers the greatest flexibility and opportunities for further design.
Water Supply
Water Supply Option Installation costs Maintenance Notes costs Mains Supply Poor May be ‘Unreliable’ Local Source Fair Good Could be difficult Reservoir Poor Fair Appropriate site needed Dig a well Fair Good Subject to survey
Water Supply Option Installation costs Maintenance Notes costs Septic Tank Fair Poor Needs secondary/ tertiary treatment Biodigester Good Environmentally friendly Stabilisation pond Fair Good No treatment required Large area needed
Solid Waste • Council collects bins twice weekly Recycling • Kerbside collection for paper/card • Local Availability of recycling banks • Possible other options from LA
Initial Conclusions And Future Projections
Initial Conclusions • Site C – Better access – “easier” excavation – Less visual impact – greatest water source
Targets 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 Future • Presentation 4 – Continuation of building design – Supply/Demand matching techniques • Presentation 5 – Final Proposal – Prime example of sustainable design
