|Climate responsive Building (SKAT, 1993)|
|4. Case studies|
The main points:
In spite of its sophisticated design the building does not fully fulfill expectations, because:
· the system of heating air by a passive solar collector is not efficient enough;
· the users are generally careless about heat conservation and do not close doors.
This house was built in 1979, at an altitude of 4000-m. The southern elevation is fully glazed, consisting of 1/3rd windows and of 2/3rd solar collectors as a solar wall for space heating. Because of the severe climate at this altitude (below zero) the collectors were designed as air heaters.
Other climatic design features were also applied:
· Curved south front for wind protection
· Buffer zones on east and west side
· built-in to the slope on the north side
Experience has shown that the concept was not fully successful:
· The human factor was not sufficiently considered; for
instance the outer doors were never closed.
· Mice had blocked the air-ducts with rice which they collect and store in the inaccessible parts of the ducts.
· The efficiency of air-heating compared to water-heating systems is low.
