Stack Effect and Wind Pressure
Utilising the benefits of the roof form in order to increase passive ventilation via the stack effect and wind pressure differentials.
Main Ventilation Requirements
Specific areas of the building require mechanical ventilation
Cooking Spaces
Toilets
Offices
Minimising costs through air tightness and passive ventilation
Energy Consumption
My main driver for heating and ventilating my project was the need to keep running costs as affordable as possible whilst reducing the reliance on fossil fuels.
Strategies were inspired by Shepherds Robsons energy efficient 'Lighthouse'
Air Tightness Strategies
Ventilation Strategies
1.large area of glazing requires thermally insulating glass
2.Polycarbonate windows allow light without heat loss
3.isolating main lobby area helps reduce heat loss
4.prefabrication of various side walls
5.using high point of window to purge stale air
6.double height space allows air movement
