PURPOSE:To make it possible to collect solar heat effectively by a method wherein a light transmissive plate is arranged outside the outer wall of the building so that a clearance is formed between the outer wall and the light transmissive plate and air heated by a solar heat collector provided in the clearance is utilized for heating the room. CONSTITUTION:The light transmissive plate 4 is arranged outside the building in parallel and spaced apart relationship with the outer wall 2 of the building with the exception of the window opening 3 of the building so that the closed space 5 is formed between the outer wall 2 and the light transmissive plate 4. Then the solar heat collector 6 is arranged within the clearance and the air heated in the clearnace 5 by the heat collector 6 is guided to a part required to be heated. More particularly, the air heated to an elevated temperature by a lighting device or the like near the ceiling of the ground floor is introduced into the clearance 5 through a lower vent hole 9, heated by the heat collector 6 and is supplied to the ceiling of the second floor from an upper vent hole 8 through a conduit 10 so as to help heat the upper floors. Further, in case where there is a plenty of sunshine in summer and no heat collection is required, the heat collector 6 is rolled up so as to reflect the thermic rays of the sun outwardly of the building to thereby prevent the interior of the building from being heated to a high temperature. |
