Concepts.
The building industry is full of jargon. Here are 25 terms explained so you understand what's happening with your building.
BBR — Danish Building and Dwelling Register
The BBR is Denmark's official register of all buildings and dwellings. It contains data on size, materials, year of construction, heating system and more — and it's public.
BIM — Building Information Modeling
BIM is a digital 3D model of a building containing data about all building elements — not just drawings, but information about materials, dimensions and properties.
BR18 — Danish Building Regulations 2018
BR18 is the Danish building code that governs all construction in Denmark — from fire safety and energy performance to accessibility and climate impact.
Building Permits in Denmark
A Danish building permit is the municipality's formal approval of your construction project. Without it, you risk being ordered to demolish what you've built.
CO₂ Limit — Danish Carbon Threshold for New Buildings
Denmark's CO₂ limit in BR18 sets a ceiling on how much carbon a new building can emit. From 2023, the limit is 12 kg CO₂-eq/m²/year for large developments.
Comprehensive Renovation Plans for Social Housing
A comprehensive renovation plan coordinates major work across a Danish social housing estate and is partly funded by the Danish National Building Fund.
Energy Labels in Denmark
The Danish energy label rates a building from A to G based on its calculated energy consumption. It's mandatory for all property sales and rentals.
EPD — Environmental Product Declaration
An EPD is a standardised document that shows a building material's environmental impact — including its carbon footprint, energy use and resource consumption.
Foundation in Construction
The foundation transfers your building's entire weight to the ground. Foundation failure is one of the most serious and expensive building defects.
GWP — Global Warming Potential
GWP measures the climate impact of a material or building in kg CO₂-equivalents. It's the fundamental unit behind carbon calculations in construction.
Heating Systems in Danish Buildings
Your heating system is the technology that warms your home. The choice of heat source has a major impact on your energy bills, carbon footprint and property value.
Land Parcels in the Danish Cadastral Register
The Danish cadastral register is the official register of all land parcels. Your cadastral number uniquely identifies your plot in the official land register.
LCA — Life Cycle Assessment
A Life Cycle Assessment measures a building's total environmental impact from raw material extraction to demolition. It's the most honest way to calculate a building's carbon footprint.
Listed Buildings in Denmark
A listed building in Denmark has the highest level of legal protection. Even minor changes require approval from the Danish Agency for Culture and Palaces.
Local Development Plans in Denmark
A local development plan is a legally binding municipal document that determines what you can build, how high, what colours are allowed and how the land can be used.
Moisture Damage in Buildings
Unwanted moisture in building structures is one of the most common causes of building damage and mould in Denmark. Here's what every homeowner should know.
Planning Zones in Denmark
Denmark divides all land into three planning zones: urban zone, rural zone and summer cottage area. Your zone determines what you can build and how your land can be used.
Property Easements in Denmark
A property easement is a registered legal restriction on your property — it may limit what you can build, plant or use your plot for, and it runs with the land.
Property Maintenance Obligations in Denmark
Danish property owners have a legal duty to keep their buildings in sound and safe condition. Neglect can trigger enforcement notices from the municipality.
Retrofit Insulation
Retrofit insulation means adding insulation to an existing building — in walls, roof or floor. For most Danish homeowners it's the fastest payback renovation investment.
Roof Structure
The roof structure is the load-bearing framework beneath the roof covering. Its type determines insulation options, lifespan and renovation needs.
SAVE Value — Danish Heritage Assessment Score
The SAVE value is a Danish heritage assessment score from 1 to 9 that determines whether a building is considered architecturally and historically significant.
Site Coverage Ratio in Denmark
The site coverage ratio determines what percentage of your plot you're allowed to build on. In Denmark it's typically 25–40% for single-family homes.
Sustainability Class in BR18
The sustainability class is a voluntary Danish building class with stricter requirements for carbon footprint, indoor climate and resource use — above the legal minimum.
Vapour Barrier in Construction
A vapour barrier is a membrane that prevents water vapour from penetrating walls and roofs — stopping mould, rot and structural damage.
