Of all the construction materials available today, concrete is perhaps the most ubiquitous and unique. Concrete is the most widely used construction material in the world and is produced and consumed in every part of our country. In fact, no construction takes place without the use of some concrete product.
In its simplest form, concrete is a mixture of cement, water and aggregates. Within this process lies the key to concrete's remarkable trait: it's plastic and can be molded or formed into any shape when newly mixed, strong and durable when hardened. These qualities explain why concrete can build skyscrapers, bridges, sidewalks, superhighways, houses and dams.

Energy and thermal performance requirements are growing and playing an increasingly significant role in building codes throughout North America. However, understanding and meeting the requirements has also become increasingly complex for building designers. At the same time, it has become clear that important decisions regarding basic enclosure assembly design and window area need to be made early in the design process to result in the most cost-effective, energy-efficient, and comfortable building.
This guide provides designers, builders, and building owners with a brief introduction to compliance options for modern building codes, and details calculation methods suitable for quickly estimating, at an early design stage, the thermal performance of concrete enclosure wall systems. The guide is not a comprehensive summary of energy codes in force or of their different interpretations across the country, which remains the responsibility of the designer of record.

Durability is the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties. Different concretes require different degrees of durability depending on the exposure environment and the properties desired. Concrete durability is one of the most important considerations in the design of new structures and when assessing the condition of existing structures.
