Construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning. Building construction is the process of adding structures to areas of land, also known as real property sites. Some construction projects are small renovations, repairs, painting, and fixing leaks. However, more complex or ambitious projects usually require additional multi-disciplinary expertise and manpower.
Building science is a field of knowledge that draws upon physics, chemistry, engineering, architecture, and the life sciences. Understanding the physical behavior of the building as a system and how this impacts energy efficiency, durability, comfort and indoor air quality is essential to innovating high-performance buildings. Modern building science attempts to work with models of the building as a system, and to apply empirical techniques to the effective solution of design problems.
Building science is concerned with heat flow through building enclosures and heat supplied to or removed from conditioned space. The laws of thermodynamics lay down the fundamental rules for understanding heat, and that means if you want to understand building science better, you need to know some thermodynamics. Temperature, moisture and air pressure all have an effect on durability of your home, indoor air quality, and whether your home is comfortable or not.
There are a few ways heat moves through at building. It sounds complicated but the basics of heat movement are really quite simple. Here are some examples.
