Bricks, tiles and DGNB

 

In Denmark, DGNB is the most widespread method of certification when it comes to rating sustainable construction. However, there are a number of international standards, all of which are based on similar principles. In Denmark, we generally use the DGNB method. Below you can read more about the various criteria that appear in the scheme. Products from Randers Tegl form an important part of a sustainable construction.

The system is based on a points scheme in which points can be accumulated throughout a construction project. The number of points that can be obtained from using bricks and tiles will vary from project to project. There are many factors that affect the envelope of a building, and these must be taken into account. We are happy to advise on how best to use our products, and we will be pleased to help you by providing information and advice throughout your project.

Below we have listed some of the areas where bricks and tiles impact positively on your DGNB rating.

 

Process

Bricks and tiles are very durable materials. They require very limited maintenance when used correctly. Bricks and tiles are harmless building materials. Any bi-product that is properly sorted and managed can be reused in the production of bricks and tiles. Used pallets are returned for reuse. Bricks and tiles ensure that buildings are healthy and suitably solid and weatherproof, and do not contain organic material that can result in the formation of mould and fungus.

Environment

Since 2018, Randers Tegl has had an environmental product declaration (known as the EPD) on many selected products. All our products will soon be EPD-certified. These can be profitably included in LCA studies, which means that you can avoid having a 30% increase in generic values.

Note that bricks do not emit or consist of environmentally harmful substances and can be used indoors and outdoors without environmental risks. Bricks and tiles also offer the highest score when it comes to the environmentally sensitive extraction of the actual building materials. Clay pits are restored to arable land once the clay has been extracted. When roof tiles are used, rainwater can be collected for various purposes, and using brick paving facilitates drainage.

Brick and tile surfaces are suitable for vegetation and for providing habitat for various species of animals, especially when this is factored into the design.

Total overall costs (LCC)

Using bricks and tiles reduces costs especially when it comes to operational costs. These materials generally ensure that the total overall costs of a building project are reasonable. Determining the necessary data for calculating costs early on in any building project is relatively easy.

Making minor changes to walls made of brick (both in load-bearing and non-load-bearing masonry) is easy too. Careful planning in the design phase ensures that recesses, doors and window cavities can be prepared for later use. Bricks and tiles have a long functional life. Roof tiles last for more than 70 years and bricks and brick paving last for more than 150 years.

Bricks and tiles help protect buildings from the effects of the sun, thereby achieving exceptional savings in running costs. When used on the inner skin of buildings, bricks have excellent properties in terms of thermal insulation.

The social aspect

Interior brick walls absorb excess heat and prevent big differences in temperature. Brick walls do not emit odours or dangerous substances. They can look very good and can provide outstanding acoustics. The ability of bricks and tiles to protect buildings from the effects of the sun also means that the building is easier on the eye. Bricks also reflect less than other building materials. Bricks and tiles can be used for functional designs.

The different structural and colour properties in bricks can be used in design solutions where such combinations are used to help a range of disabilities. Over time, bricks and tiles have allowed artists to express a range of artistic styles. Bricks can also be used for structures and features inside buildings such as stairs and window seats.

Technology

Bricks and tiles do not contain PVC and do not therefore emit toxic waste gas in the event of a fire. Buildings built using bricks and tiles, as well as other materials, can achieve high u-values. Thermal bridges can be avoided with careful planning in the design phase. A brick-built building with filled mortar joints is solid and weatherproof.

Using brick walls for outer walls and partitions helps a building to retain heat.

Bricks, tiles and brick paving are all materials that can easily be recycled. Almost 100% of these materials can be recycled if they are carefully dismantled. We recommend using binders and mortars that can be easily removed.

There are currently environmental product declarations for selected types of bricks and tiles. All products from Randers Tegl will soon be EPD-certified. These products will be continuously updated while we continue to make improvements to our production process and transition to green energy sources.
