Project 3: Finalising scheme

Some finalised sketches of the scheme.







actually added the screen sheilding the northern glazing as it was a very large expance and the factor of glair on the basketball court had een an unconsidered factor. Fixed and manouvarable slats have been put in place to counted this effect, whilst still llowing light in.





Materiality wise i am looking at using polished concrete floors and rammed earth walls for thermal mass, angled reflective kingspan roofs to deflect unwanted sunlight and also allow solar panels to catch the rays.





The kingspan website was really useful in that it made avaliable a variaty of details spesifying exactly how their product would work with various methods of construction - I found really interesting! I used this to work ut a bit of my detail.



The configuration of these details is crutial to the effectiveness of the system. Particuallary around glazing and roof and wall connections the intrusion of water or wind can be detrimental to the effect of the system causing fluctuating air temeratures and atmosphere.

Hopefully with the incorporatin of various design elements listed below, I have managed to addrees some f the piviotal engins in regards to sustainability ane enironmentally friendly building design and lifecycle
Sustainability
  • Large north facing glazed areas to ensure good daylight – windows double glazed and tinted
  • Panels of louvered windows allow natural cross ventilation, operable solar control and sun shading
  • Outside air is drawn from the cooler south-side lower level of the gym and dragged past the colder thermal mass of the concrete walls. It is then draws up through a riser to the upper floor where is is distributed via outlets to provide cool air.
  • East and West windows kept at a minimum
  • Thick foil-coated insulation retains winter warmth while reflecting summer heat.
  • The over sailing roof offers shade
  • Reflective roof material deflects heat
  • Thermal mass provided through concrete floors and (rammed earth) walls, also acting to stabilise internal air temperature
  • Hot water needs will be provided by the Apricus solar hot water system.
  • Rainwater tanks collect water for use in the toilets and garden/ outdoor sports areas
  • BT bamboo flooring used in the gymnasium
  • Plantation pine used for structural timber
  • Solar hot water system installed with panels on the southern for angled at 30 degrees
