13.6 : 設計例: コンクリート建築における持続可能性

A construction firm specializing in concrete buildings constructed a sustainable commercial building. 

The various sustainable practices incorporated in the concrete building include providing a concrete parking area under the building to create more open areas around it.

Some portions of the open areas use permeable concrete paver blocks that allow rainwater to flow through them.

Rainwater is collected and stored in an underground concrete cistern, from where it can be reused, facilitating water-efficient construction.

Using ready-mixed concrete with regional materials and some portions of slag cement, fly ash, and recycled aggregates enables material cost savings.

Incorporating reinforcements made from recycled steel adds to the material recovery.

Floors and ceilings are made of exposed concrete to minimize the use of coatings.

Using concrete roofing material with a high solar reflectance index and insulated concrete systems reduce the demand for air conditioning systems.

Lastly, a small depth from the building's facade to its core and large column-free spaces maximize the entry of natural daylight, increasing the energy efficiency of the building
