Modern Ventilation can provide a good indoor air quality for people who are living in the house, and make sure the building performance is effective enough and improves the health and comfort. Carbon Dioxide, waste, pollution and ecology are always the factors accessing sustainabllity. Bad ventilation could cause energy waste. Besides, under the Building Regulation of UK Rule F (Ventilation), it ensure houses with good indoor air quality and ventilation.
Below is the link of Part F Regulation:
Link about code of sustainable home:
Fans, windows and vents are the types of ventilation which provided in the pass. They all can extract the room moisture and decrease the humidity. Extractor fan is the most common type of ventilation in bathroom. It turns on when the lights is on, and it will stay for 5-10 minutes on when the light is off. (Photo A). This type of fan it normally can see it on top of the bathroom window. For those bathroom without a window, it normally use Vents fan (Photo B), the duct connect between Sofie vent and fan and ventilate the bathroom. In the modern days, these types of ventilation depends on the type of dwellings.

Mechanical ventilation with heat recovery (MVHR) is one of the modern type of ventilation. The idea of MVHR is like “exchange” the cold air to hot air, vice versa. Air from the extract hood and bathroom is removed and exchange to fresh air. However, some houses are small may just need a small amount of input heat, therefore MVHR may not applicable to some dwellings.
As Oxley Wood is an example of sustainable house, the designer chose to apply EcoHats (Photo D) in the dwellings. EcoHats is a new system of ventilation. It is fitted on the top of the roof. The diffuser inside the base unit filtered fresh air into the building, and it reuses the air due to it can prevent the loss of heat. Besides, it uses solar energy to provides solar preheated the air . Thus, it can decrease 23% of carbon dioxide emissions.

In addition, one other advantage of a dwelling in Oxley Wood is some areas in the houses does not have a window, and the designer put a ventilation spacer at those places. It helps the enteral house can always getting fresh air. It led to more energy efficiency. (Photo E). As I mentioned about window, windows are applied in all bathrooms, it helps the bathroom ventilate the humidity after shower quickly. (Photo F). Balcony also can help the ventilation. In Oxley wood, every floor fitted with a big balcony, as the doors of the balcony can open, during the summer time, it can ventilate the heat in the house. It helps cool down the temperature during summer time. (Photo G)
