We Asked Chat GPT about Building Performance

We’ve all heard about Chat GPT by now, how it’s taking over the creative world by storm, so we decided to ask it to write an article about Building Performance in relation to air tightness, sound insulation and ventilation.

Here’s the video showing the result… (transcript below)

The information really does depend on how you asked the question or phrase. We asked it the same question a couple of times and got similar but not identical results. One of the searches related sound insulation to air quality! It’ll be interesting to see how this information is developed over time.


Building performance is a critical consideration for architects, builders, and homeowners alike. When constructing a building, there are several factors that need to be taken into account to ensure optimal performance. These factors include air tightness, sound insulation, and ventilation. In this article, we will discuss these factors in more detail and how they relate to building performance.

Air Tightness

Air tightness is the measure of how much air can pass through the building envelope. A building with poor air tightness can experience heat loss, moisture damage, and poor indoor air quality. To improve air tightness, builders can use high-quality building materials, such as double-glazed windows and doors, and properly seal gaps and cracks in the building envelope.

Air tightness is crucial for building performance, especially in cold climates. In a poorly insulated and air tight building, heat loss can be significant, leading to higher energy bills and decreased comfort. Moreover, an air leak can allow moisture to enter the building, leading to mould growth, rot, and structural damage. Therefore, it is essential to maintain an appropriate level of air tightness to prevent these issues.

Sound Insulation

Sound insulation is another critical factor that affects building performance. A building with poor sound insulation can experience noise pollution from outside, leading to decreased comfort and productivity for occupants. Sound insulation can be improved by using sound-absorbing materials such as insulation, acoustic panels, and double-glazed windows.

A building with good sound insulation can also help to increase privacy, prevent sound transmission between different rooms, and reduce noise from outside. This is especially important for buildings located in noisy areas, such as near highways or busy streets.


Ventilation is the process of exchanging indoor air with outdoor air to improve indoor air quality. A well-ventilated building can prevent the build-up of pollutants, such as carbon dioxide and volatile organic compounds (VOCs), which can be harmful to human health. Proper ventilation can also prevent the growth of mould and bacteria, which can cause respiratory problems and allergies.

To improve ventilation, builders can incorporate mechanical ventilation systems, such as heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs). These systems can help to circulate fresh air while also recovering heat from the outgoing air to reduce energy consumption.


In conclusion, building performance is dependent on several critical factors, including air tightness, sound insulation, and ventilation. A building with good air tightness can prevent heat loss, moisture damage, and improve energy efficiency. A building with good sound insulation can increase comfort, privacy, and productivity. Lastly, proper ventilation can improve indoor air quality and prevent the growth of pollutants and mould.

When constructing a building, it is essential to consider these factors to ensure optimal performance. By incorporating high-quality building materials and systems, such as mechanical ventilation, builders can create a comfortable and healthy indoor environment for occupants.
