2.1 Different types of Passive house Construction The images below show some of the various different wall constructions that are often used to build a Passive house. Figure 2.1: different types of wall construction used to build passive houses which should give the desired U-value of 0.15W/m2K or less Some of these options would be more structurally sound compared to others. Some of the above options may be used that can often make a passive build cheaper than a conventional build.
2.2 Classification
Table 2.1: outlines the specification requirements for a house to be classified as passive.
Space Heating Demand not to exceed 15kWh annually OR 10W (peak demand) per square metre of usable living space
Space Cooling Demand roughly matches the heat demand with an …show more content…
3.2 Case Study – Rosslare
A case study was carried out in Rosslare on 1 of the 8 Family homes that were built in this project.
The spec for the house was as follows:
• The two story house had a floor area of 167m2 or 1,806sq.ft.
• Space heating demand of 10KWh/(m2a).
• Windows when installed a U-value of 0.85W(m2K).
• A Dwelling heat load of 1.5KW.
• The building requires a structural air tightness of less than 0.6h-1.
This case study only took into account the construction of the house, solely taking into account the materials and requirement that differ from a standard conventional build. This meant that land cost, planning permission, and furnishing the home were not taking into account.
Table 3.1: This table taken show the breakdown of costs associated with building this specific Passive house.
