Worked Solution & Example Answer:The elevation and ground floor plan of a house are shown - Leaving Cert Construction Studies - Question 6 - 2011
Step 1
With reference to the design shown, discuss in detail, using notes and freehand sketches, three features of the design that ensure the house has low environmental impact.
Answer
-
Rainwater Harvesting System: The design incorporates a rainwater harvesting system that collects rainwater from the roof and other surfaces, storing it in an above-ground storage tank. This reduces the dependency on municipal water supply, lowering both operational costs and environmental impact.
-
Solar Panels: The inclusion of solar panels on the roof allows the house to utilize renewable energy, significantly decreasing reliance on fossil fuels. These panels can provide substantial amounts of hot water, achieving an efficiency of up to 60% depending on seasonal variations.
-
Use of Sustainable Materials: The construction material consists of concrete blocks and cedar cladding. These materials are chosen for their durability and low embodied energy, minimizing the overall environmental footprint of the building during its lifecycle.
Step 2
Discuss in detail the importance of each of the following when designing environmentally sustainable housing: form of the house
Answer
- Form of the House: Choosing a narrow plan with optimal orientation maximizes natural light while minimizing heating needs. It also allows for efficient use of space, reducing the amount of materials required in construction.
Step 3
Discuss in detail the importance of each of the following when designing environmentally sustainable housing: materials and labour
Answer
- Materials and Labour: Utilizing local materials reduces transportation costs and emissions associated with transporting building supplies. Additionally, the use of local skilled labour can enhance community engagement and sustainability, creating jobs and reducing the carbon footprint.
Step 4
Discuss in detail the importance of each of the following when designing environmentally sustainable housing: design for lifetime use
Answer
- Design for Lifetime Use: Implementing adaptable spaces and features accommodates changing needs over time, which prolongs the useful life of the building. For instance, integrating features for accessibility ensures the house can be used by individuals regardless of age or ability.
