Worked Solution & Example Answer:The elevation and ground floor plan of a house are shown - Leaving Cert Construction Studies - Question 6 - 2012
Step 1
With reference to the design shown, discuss in detail, using notes and freehand sketches, three features of the design that reflect the sustainable ideal of doing more with less for longer.
Answer
-
Use of Space: The design maximizes the use of space with a compact layout, featuring three bedrooms and a bathroom on the upper floor. This minimizes the environmental footprint while maintaining functionality and comfort. By keeping the design compact, it reduces material usage and resource consumption during construction, promoting sustainability.
-
Roof Design: The house features a roof design that includes multiple breaks and angles, maximizing daylight penetration with minimal artificial lighting needs. This design reduces energy demands and reliance on fossil fuels, reflecting a sustainable approach by utilizing natural resources effectively.
-
Sustainable Materials: The use of timber frame construction for the external walls, combined with a concrete block outer leaf, enhances the house's energy efficiency. Timber, being a renewable resource, lowers embodied energy costs, while the concrete provides durability and thermal mass, which aids in maintaining comfortable indoor temperatures.
Step 2
Discuss in detail the importance of each of the following when designing an environmentally sustainable dwelling house: orientation of house
Answer
The orientation of the house is crucial as it influences its energy efficiency and comfort. Positioning the house to face south maximizes sunlight exposure, reducing heating costs during winter and utilizing passive solar gain. Proper orientation can minimize energy consumption for heating, leading to lower carbon footprints and creating a comfortable living environment.
Step 3
Discuss in detail the importance of each of the following when designing an environmentally sustainable dwelling house: flexibility of design
Answer
Flexibility in design is essential for accommodating the changing needs of occupants over time. A well-thought-out flexible design allows for easy adaptations, making it possible to repurpose spaces for different functions, which contributes to sustainability by extending the life of the house. Universal design principles support accessibility for all ages and abilities, ensuring the dwelling can adapt as families grow or change.
Step 4
Discuss in detail the importance of each of the following when designing an environmentally sustainable dwelling house: sourcing of materials
Answer
Sourcing of materials significantly impacts a building's environmental sustainability. Using locally sourced materials reduces transportation emissions and supports local economies. Additionally, selecting renewable resources, like sustainably harvested timber, lowers the embodied energy associated with construction. Incorporating recycled materials and low-impact products further minimizes environmental harm, supporting a more sustainable construction process.
