Worked Solution & Example Answer:The elevation and ground floor plan of a house are shown - Leaving Cert Construction Studies - Question 6 - 2013
Step 1
With reference to the design shown, discuss in detail, using notes and freehand sketches, three features of the design that contribute to the house having a low environmental impact.
Answer
-
Steep Pitched Roof
A steep pitched roof permits additional living space by utilizing the attic, thus making the most of vertical space. It also minimizes energy consumption because the design reduces heat loss during cold months, enhancing heating costs. The roof can incorporate solar panels at an optimal angle (45°), which maximizes solar energy absorption, reducing reliance on conventional energy sources. -
Rainwater Harvesting System
The house is equipped with a rainwater harvesting system that collects rainwater from roof surfaces and stores it in an above-ground system. This minimizes water consumption and reduces the reliance on municipal water systems. In addition, the use of rainwater for gardening helps in maintaining the ecological balance in the environment. -
Use of Sustainable Materials
The use of timber frame construction lowers the carbon footprint. Timber is renewable and its low embodied energy makes it less harmful to the environment compared to traditional materials like concrete. This choice contributes to a lower CO2 emission profile, aligning with sustainable building practices.
Step 2
Discuss in detail the importance of each of the following when designing a house suitable for first-time buyers:
Answer
-
Modest in Scale
A modest scale minimizes land use and construction costs, making it an attractive option for first-time buyers who often have budget constraints. By limiting the floor area, the house remains affordable in terms of mortgage, utility, and maintenance costs. -
Easy to Modify
Flexibility in design allows for future adaptations as family needs change or as financial situations improve. A house that can easily be modified or expanded will appeal to first-time buyers who may eventually need more space without the cost of moving. -
Proximity to Services
Being close to essential services like schools, healthcare, and public transport is crucial. This reduces long commutes, lowers transport costs, and promotes a more sustainable lifestyle. Access to amenities like parks and grocery stores enhances the living experience for first-time buyers.
