How do we take advantage of passive solar energy in this 1964 raised ranch from only the gable end?
We have a client in a Zone 5 climate. His house does not have any south-facing fenestrations to take advantage of passive solar energy.
He is proposing to remove a gable-end chimney and fireplace, which occupies a good portion of the south facing gable wall, and replace it with low U, high solar heat gain glass to superheat his house interior, hoping the thermal mass of the drywall interior will be enough to store the heat energy his family would need at night. His design includes superinsulated polyiso interior shutters to cover the windows at night.
I feel that with better sealing of house penetrations, increased ceiling insulation and appropriate modifications to the chimney, he would be better served by using its 2-story mass with a glass surround to create a Trombe wall with blower to achieve a better use of his southern exposure without risking the house interior to such temperature swings and related potential problems.
What direction or suggestions should we pursue to properly and safely utilize the passive solar exposure he has to heat his home?
