Introduction: ● Background ● Relevance to History ● Significance ● Challenges faced ● Future of this technology

Background: ● Passive heating and cooling is a building design ○ Focused on innovation ○ Utilizes indoor climate control with low energy consumption

Relevance to History: In Germany 70 million square meters (1995) to 230 million square meters (2005). Rain water concrete cistern cycle. Benefit : Temperature is more stable than the ambient air temperature Avoids contamination of water. (Kalz). Setback: Weather Dependant

Relevance to History: In America Solar Chimney Benefits Reliable Cost Effective Setbacks (Maerefat). Depends on Temperature Depends on Solar Energy

Why is it significant? ● Estimated savings around 70% when compared to traditionally air conditioned buildings (Santamouris, Mattheos, and Dionysia Kolokotsa) ● No decrease in the comfort conditions of the buildings (Orosa, José A. , and Armando C. Oliveira)

Where Passive Heating currently is? ● Many options when it comes to technologies that can be applied: ○ Permeable coverings (Orosa, José A. , and Armando C. Oliveira) ○ The use of the ground as a heat sink (Santamouris, Mattheos, and Dionysia Kolokotsa) ○ Night time ventilation ○ Special roof systems as thermal buffers (Wong, N. h. , and S. Li. ) ○ Building orientation, i. e. North-South in sunny climates ○ Increasing the thickness of the external wall on the sides with the most sun exposure (east and west) ○ Automated window shading

Challenges: ● High initial cost ● More difficult to achieve desired temperatures in extreme climates ● Cistern - Generated more heat in comparison to cooling. ● Difficult to incorporate multiple technologies for climates with changing seasons

Future of Passive Heating and Cooling: More passive heating and cooling technologies will be developed and researched It will be used to control the climate in most new buildings
