The thesis deals with architectural solutions based on thermodynamic calculations for the integration of air-based active solar energy systems in energy conserving buildings (following climatic design guidelines).
To improve the thermal response of the envelope (skin) and thermal ,mass of energy conserving high-rise buildings, to the ever-changing external climatic conditions, an integrated active solar energy system (for heating and cooling) combined with an improved passive window system, is proposed. Significant reductions of energy needed for thermal comfort conditions, were obtained.
The balanced integration of the active solar energy system, with the climatic design guidelines of energy conserving buildings (including passive solutions) is referred to as “integrated climatic design”. Integrated climatic design guidelines for office and apartment high-rise buildings are developed and architectural solutions are proposed, suitable for Israel, and Mediterranean countries with similar weather and building practices.
The unique feature of the proposed integrated air-based active solar energy system is characterized by a rational and simple, decentralized and modular design solution. The building components are simultaneously heating system components. South (±30°) oriented facades perform as air solar collectors and structural hollow concrete floor slabsperform as thermal storage. While the south (±3O°) oriented rooms are heated by passive solar energy systems the north oriented are heated by the active solar energy system. South (±30°) oriented windows are integrated with operable internal venetian blinds (with slats black on one side and white on the other). With the black slats facing the sun, the window performs as a passive solar air collector, with a reduction of glare disturbance in winter.
With the white slats undesired heat is screen out and reduced, in summer.
Passive cooling by shading and natural (or forced) ventilation are considered.
