Redlining Analysis - Combined

Building Regulation – BR18 Ch. 9 – Building layout Layout of building with access for the public §214. Buildings with access for the public must be designed with sizes and layouts of the individual rooms which ensures that the functions and activities to be carried out in the building can be carried out functionally and safely. (2) In storeys where public toilet facilities are established, minimum one room must be established which fulfils the following requirements: 1) Level access to the toilet room. 2) Free passage through the door to the toilet rooms must be minimum 0.77 metres. 3) Washbasin and toilet must be located across a corner on adjacent walls to enable hand wash by a person sitting on the toilet. 4) Free distance of minimum 0.90 metres on the side of the toilet facing away from the washbasin. The wall next to the toilet which faces away from the washbasin must be free of permanent fixtures. 5) A free area with a diameter of 1.5 metres in front of the toilet and free of the door opening range must be available for manoeuvring. 6) The toilet seat must be placed at a height of approx. 0.48 metres. 7) Foldable armrests must be established at a height of 0.80 metres on both sides of the toilet. 8) The washbasin must be established at a height of approx. 0.80 m, and the drain behind the washbasin must be installed further back. §215. Minimum one toilet room equipped according to s. 214 must be established on the ground floor or on other storeys accessible via lift, stairlift, etc.

Layout of standard classrooms §228. The area and volume of standard classrooms in schools, etc. and of living spaces in day-care facilities for children must be appropriate for the number of children and employees at the facility. §229. Living spaces in schools and day-care facilities must have: 1) Minimum 3 sq. metres free floor space per child in day nurseries and 2 sq. metres per child in kindergartens. 2) A volume of minimum 6 cubic metres per person in standard classrooms at schools, etc.

Redlining Analysis - Combined

Building Regulation – BR18 Ch.5 – Fire

§99. In case of a fire, buildings and building parts must be sufficiently fire resistant. §100. The fire resistance of load-bearing building parts are determined either by standard fire effect or by use of a natural fire process as described in DS/EN 1991-1-2 Eurocode 1: Load on load-bearing structures – Part 1-2: General loads – Fire load and DS/EN 1991-1-2 DK NA National annex to Eurocode 1: Load on buildings – Part 1-2: General loads – Fire loads.

Ch. 15 – Structure Special provisions for wooden structures §348. In addition to the provisions of s. 344, planning and construction of wooden structures must be carried out in accordance with: 1) DS/EN 1995-1-1 Wooden structures, General rules and rules for building structures with DS/EN 1995-1-1 DK NA. 2) DS/EN 1995-1-2 Wooden structures, Fire safety dimensioning with DS/EN 1995-1-2 DK NA.

Ch. 17 – Sound §374. For non-residential buildings it must be ensured with due consideration of the use of the building that persons in the building are not disturbed by sound from adjacent rooms, from installations in the building or from roads and railways in the surrounding area.

§375. If rooms with noisy activities in the same or adjacent buildings are adjacent to teaching rooms or living rooms, sound-proofing must

be carried out.

Ch. 18 – Light and view of surroundings §377. Buildings must have light conditions that ensure that no risk will occur to the health, safety and comfort of people. Sufficient daylight and view of the surroundings must be ensured as well as sufficient electric lighting with due consideration of the use.

§381. Windows must be established, placed and possibly shielded to ensure that direct sunlight does not cause overheating of the rooms and to prevent nuisance form direct sun radiation.

Redlining Analysis - Combined

Building Regulation – BR18 Ch.11 – Energy consumption General minimum requirements for building envelopes §257. Each building part must be insulated to ensure that the heat loss coefficients do not exceed the values stated in Appendix 2, Table 1. In certain cases, e.g. in case of tall buildings or complicated soil conditions, the requirements for linear thermal transmittance at the foundation cannot be observed. In such cases, a corresponding higher linear thermal transmittance coefficient can be accepted if problems with moisture and condensation do not occur. Heating of buildings §293. Heating of buildings must be based on renewable energy. §294. In buildings located in area where connection to a district heating supply grid is possible, buildings may be heated by district heating irrespective of s. 293.

Ch. 19 – Indoor climate §386. In rooms where people stay for longer periods of time, it

must be ensured that a satisfactory thermal indoor climate in terms of health and comfort can be maintained during the intended use and activities of the room.

Ch. 22 – Ventilation Ventilation of day-care facilities and teaching rooms §447. Living spaces in day-care facilities, teaching rooms in schools, etc. must be ventilated via a ventilation system which includes injection, evacuation and heat recovery for heating of the injection air. (2) In day-care facilities, injection of outdoor air and evacuation must be minimum 3.0 l/s per child and minimum 5.0 l/s per adult and 0.35 l/s per sq. metre floor area. In teaching rooms in schools, etc., the injection of outdoor air and evacuation must be minimum 5.0 l/s per person and 0.35 l/s per sq. metre floor area. In day-care facilities and teaching rooms in schools, etc. it must also be ensured that the maximum CO2 content of the indoor air does not exceed 1,000 ppm for the dimensioned conditions. (3) In a ventilation system with demand-controlled ventilation is used, the stated air quantities can be derogated from when the demand is reduced. During the period of use, ventilation may not be less than 0.35 l/s per sq. metre floor area.
