Building Regulations 2015​

Building work in new and altered buildings in Denmark

The Building Regulations contain the Danish rules for building work in new buildings, extensions, conversions and other rebuilding work, as well as changes in the use of buildings that are important in relation to the Danish Building Act or the Building Regulations, the demolition of buildings and alterations and other rebuilding work that may affect the consumption of energy in the building. The Building Regulations apply to building work carried out in the Danish market.

Their primary field of application is multi-storey buildings for residential purposes and all kinds of commercial, industrial and institutional buildings, including the categories listed in section 11 of the Danish Building Act, single-family houses for permanent residence, either as detached single-family houses or linked single-family houses, holiday homes in summer house areas, allotment sheds, campsite cabins and garages, outbuildings, and other secondary buildings.

(1) EN 1991-1-4 gives guidance on the determination of natural wind actions for the structural design of building and civil engineering works for each of the loaded areas under consideration. This includes the whole structure or parts of the structure or elements attached to the structure, e. g. components, cladding units and their fixings, safety and noise barriers.
(2) This Part is applicable to:
. Buildings and civil engineering works with heights up to 200 m. See also (11).
. Bridges having no span greater than 200 m, provided that they satisfy the criteria for dynamic response, see (11) and 8.2.
(3) This part is intended to predict characteristic wind actions on land-based structures, their components and appendages.
(4) Certain aspects necessary to determine wind actions on a structure are dependent on the location and on the availability and quality of meteorological data, the type of terrain, etc. These need to be provided in the National Annex and Annex A, through National choice by notes in the text as indicated. Default values and methods are given in the main text, where the National Annex does not provide information.
(5) Annex A gives illustrations of the terrain categories and provides rules for the effects of orography including displacement height, roughness change, influence of landscape and influence of neighbouring structures.
(6) Annex B and C give alternative procedures for calculating the structural factor cscd.
(7) Annex D gives cscd factors for different types of structures.
(8) Annex E gives rules for vortex induced response and some guidance on other aeroelastic effects.
(9) Annex F gives dynamic characteristics of structures with linear behaviour
(10) This part does not give guidance on local thermal effects on the characteristic wind, e.g. strong arctic thermal surface inversion or funnelling or tornadoes.
11) This part does not give guidance on the following aspects:
