Worked Solution & Example Answer:The following considerations are important in passive solar design: - insulation; - orientation and shade; - energy efficient glazing and frames - Leaving Cert Construction Studies - Question 10 - 2008
Step 1
Using notes and freehand sketches, propose a design layout for the rooms adjoining the sunspace that would maximise the passive solar heat gain from the sunspace.
Answer
To maximize passive solar heat gain:
-
Room Layout: The living areas, such as the living room and kitchen, should be located adjacent to the sunspace. These rooms can benefit directly from the solar gain captured in the sunspace during the day.
-
Multi-Function Spaces: Create multi-functional spaces that allow for easy movement of heat and light. For instance, an open plan design connecting the sunspace to the main living area can enhance heat distribution throughout the space.
-
Thermal Mass: Installing materials with high thermal mass (e.g., concrete or stone floors) in the rooms adjacent to the sunspace can absorb heat during the day and release it at night, thus evening out temperature fluctuations.
-
Double Glazing: Ensure all windows facing the sunspace are at least double-glazed to minimize heat loss and maximize solar gain. Incorporate operable windows or vents for cross-ventilation to prevent overheating during the peak heat times.
-
Sunspace Design: Use large windows and skylights in the sunspace to enhance direct sunlight exposure. The sunspace can serve as a buffer zone, moderating the temperatures in adjoining rooms.
Step 2
Give two reasons for the proposed room layout adjoining the sunspace.
Answer
-
Enhanced Solar Gain: The proposed room layout maximizes solar heat gain from the sunspace, particularly in winter months, improving overall energy efficiency and comfort.
-
Improved Ventilation and Comfort: Rooms that are designed adjacent to the sunspace benefit from improved natural ventilation and allow for a more pleasant living environment, making them warmer in winter and cooler in summer due to the thermal regulation provided by the sunspace.
