Antananarivo Solar Air Conditioning

Does Antananarivo have a cooling period?

We can observe that Antananarivo does not have a cooling period but some hours during summer that are above the thermal comfort zone limits. This matches the case of Antananarivo, which is located at an altitude of 1300 m above sea level.

How climatic zoning enables a passive solar design in Antananarivo & Toamasina?

Our climatic zoning allowed us to place Antananarivo in Zone 3b and Toamasina in Zone 4. This enables a quick determination of a passive solar design and the evaluation of their (passive design measures) potential application for building designs in these major cities of Madagascar.

How much heat does Antananarivo need?

As shown in Fig. 8b, Antananarivo has 22% of its hours in the temperature comfort zone, the majority of the year it would need passive heating (18.5) coupled with high internal heat gains (35.5). As shown in Fig. 8 c, Toamasina presents an extreme level of average humidity with more than 81% of the year that is above 80% of relative humidity.

Are thermal comfort models suitable for Toamasina and Antananarivo?

We advise further investigation into the most fit and proper thermal comfort models that could be suited to Toamasina and Antananarivo. We also recommend further studies defining thermal comfort boundaries for heating and cooling demand estimation in Madagascar’s urban settlements (Roshan et al., 2017 ).

Can solar thermal air conditioning reduce the footprint of solar-thermal air conditioning system?

New development activities are necessary in order to promote market integration and to reduce the cost of using solar-thermal air conditioning in buildings. Such new systems will be a future option for sunny climates zone. The aim of this project was reducing the footprint of solar thermal air conditioning system.

What zone is Antananarivo in?

Antananarivo is in Zone 3b and Toamasina in Zone 4. Table 1. Climate characteristics. 3.2. Thermal comfort models
