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.

Setback: Weather Dependant

(Kalz).

Relevance to History:In America

Solar Chimney

Benefits

Reliable

Cost Effective

Setbacks

Depends on Temperature

Depends on Solar Energy

(Maerefat).

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
