Primary School - Chyne New School, 2015
The main intention is to provide comfort to the occupants while having a sustainable building, which works as a school and cultural centre for the community, and also as an energy power source. Some conclusions were drawn after Chyne´s climate and context analysis: low solar radiation in this latitude provides no scope for solar passive heating during Czech Republic´s long winters with large significant diurnal thermal difference. Therefore, the use of thermal insulation and mass are essential. Ventilation is advised during warm periods due to high temperatures and internal heat gains. Wind shields are needed for protection against high wind speeds in a non-obstructed context, as Chyne´s urban morphology.
The form, section, orientation, deep plan and compactness allow for an efficiency of the program, cost and energy. The passive strategies used are: natural daylighting and ventilation, using atriums and patios with openable windows; a gym as a buffer space; overhangs, shutters and blinds for solar control; canadian tunnels for heating, cooling and fresh air; mechanical ventilation with heat recovery; external insulation without thermal bridging; triple glazing windows with timber frame; green roofs for acoustic and thermal insulation.
Regarding the energy concept, a biomass renewable energy system is adopted using any kind of waste to generate energy. The main idea is to provide clean energy using a two-stage strategy. First the boiler will generate electricity from school waste. Second it will provide energy for the whole community, using their own waste, waste from local industries and the surrounding woods. Other solutions include low maintenance and manual systems, use of LEDs, occupancy sensors and schedules for lights and water, “A+” rating equipment, use of bikes, car sharing, electrical charging points and “green days” for the community.
