2016 Construction Studies Higher Level Question 10 a

Concise Summary of 2016 Higher Level Construction Studies Question 10a In the YouTube video, the speaker discusses Question 10a from the 2016 higher-level construction studies paper. This question focuses on Passive House design principles, particularly on minimizing heat loss and maximizing heat gain storage. The question presents three options (foundation, ground floor, walls) for maximizing heat storage in a Passive House, requiring two options to be selected. It also involves addressing overheating issues and proposing design details to reduce overheating risks. The speaker chooses to focus on ground floor and walls for their sketches. For the ground floor, they showcase elements like a concrete slab, insulation, DPM, aerated block, and insulation thicknesses to illustrate best practices for minimizing heat loss. Similarly, for the walls, the speaker highlights the use of the internal leaf as a storage heater, the importance of airtightness, and the role of insulation and external factors in heat retention. Regarding overheating reasons in a Passive House, the speaker emphasizes the impact of large glazed windows facing south or southwest for maximizing solar heat gain and potentially causing overheating. Additionally, the airtight design of Passive Houses can lead to overheating by trapping warm air inside. To counteract overheating risks, the speaker suggests design features like extended eaves for shading and strategic tree planting to filter sunlight. The video concludes by exploring the advantages and disadvantages of mandating Passive House standards for all new houses in Ireland. While Passive Houses reduce the need for fossil fuels, cut CO2 emissions, and save long-term heating costs, their initial high costs and the requirement for skilled construction teams pose challenges. In summary, the video delves into the practical application of Passive House design principles, emphasizing key elements like solar heat utilization, airtightness, insulation, and thermal mass. It illustrates how thoughtful design choices can mitigate overheating risks and maximize energy efficiency in construction projects.
