Climate Design

1. Climate Design Industrial Building BLOB ZAPPI Informatics • Self breathing building • Natural ventilation of buildings can play a significant part in reducing the energy consumption and - costs. To obtain a guaranteed operation of the system and a high thermal comfort, research has to be done on several elements. • Working principle • One side of the building will function as a chimney. At the other side of the building slots will be made to enable outside air entering the building. The chimney effect will pull this ventilation air into the building at each floor level. Out of the floor the air will flow to the ceiling level and via an opening in the partition wall to the corridor. From an opening in the corridor ceiling the air will enter directly the space under each floor to exchange the warmth to the fresh air and will leave the building through the chimney. • Using solar energy to heat up the water for the floor heating can complete the system. Also a combination with energy aquifer storage can be considered. • Both colouring the facade in black and silver and the use of sunscreens will contribute to the functioning of the system. Implementation of new building materials with specific building physics needs to be studied. • Leo de Ruijsscher • p.m.

2. Climate Design Industrial Building BLOB ZAPPI Informatics • Self breathing building • The research can be done in three independent phases; • Phase 1 - The feasibility of the system • Is the chimney effect a feasible option? • What will be the minimum building height to assure • functioning of the chimney effect? • First estimate, of the required ventilation openings in the • building facade • First estimate, of the necessary building surface for heat • exchange purpose • Phase 2 - The working of the system • Required air quantities • Air-supply without draught complaints • Required amount of energy • The most economic energy source • Principle of the heat exchange • Operation in summer and winter • Way of filtering the fresh air • Phase 3 - The application in the building concept • Integration with the building structure • Design of the most suitable building facade • Impact on the contribution of different building materials • Acoustic consequences • The application in relation to the building function • Approval on the overall function and feasibility of this • concept • Rough cost estimate of the system • Leo de Ruijsscher • p.m.
