Aerius calculation
The AERIUS calculation tool is part of the Dutch integrated approach to nitrogen (or PAS, from the Dutch Programmatische Aanpak Stikstof). It is used to calculate the nitrogen deposition on Natura 2000 areas as a result of projects and plans. Pursuant to the Dutch Nature Conservation Act, these calculations are mandatory for permit granting.

Beyond Eyes

Building Information Model (BIM)
A central, digital platform that combines all relevant information during the construction process and which is used by all parties involved to achieve consistent interpretation and to steer the construction process in the right direction. This leads to a digital (3D) model of the structure to be realised.

BREEAM score
Building Research Establishment Environmental Assessment Method. BREEAM-NL has been the certification method for a sustainably built environment since 2009. This method can be used to assess projects for overall sustainability.

Chain integration
Cooperation within and between the successive links within an organisation or business column, from suppliers right through to the client. 

Climate adaptation
Climate adaptation combats the effects of climate change and could help the Netherlands become resistant to climate change. Adaptation is made possible by setting climate buffers

CO2 credits
A CO₂ or carbon credit is a tradable unit that allows an organisation to offset its own CO₂ emissions by reducing CO₂ emissions elsewhere.

CO2 emissions
CO2 (carbon dioxide) emissions measured over a period of time.

Financial parties that act as custodians for shares.

DBFM contract
DBFM stands for Design, Build, Finance and Maintain, a type of contract under which the contractor is responsible for both the design and building of the project, as well as financing and total maintenance. It often concerns long-term, large infrastructural projects in ground, road and waterway construction (such as roads, locks and bridges) and property development.

Energy transition
This is the transition from fossil fuels (natural gas, coal, oil) to sustainable energy (wind, solar, biomass and hydrogen). Targets and the measures to achieve these targets are laid down in the Climate agreement.

Generic Gate Instructions (Dutch - GPI)
This is a uniform set of safety instructions followed by everybody who enters a building site: this is mandatory at all Dutch building sites from 1 April 2019. 

An internal safety improvement programme designed to eliminate accidents (‘No accidents’) and improve safety and safety awareness in the organisation.

Green Deal
Green deals are agreements between organisations, citizens and public sector bodies to provide space for innovative initiatives from society to accelerate the transition to a sustainable economy.

Greenhouse Gas Protocol
This is a protocol initiated by the World Business Council for Sustainable Development and the World Resources Institute, together with a number of NGOs, including the WWF and a number of companies, including Royal Dutch/Shell. The aim is to develop procedures and instruction manuals for the calculation and reporting of greenhouse gas emissions.

Fleet review
The annual review of know-how, talents and competencies of Heijmans’ employees.

Heijmans B’woond
Renovation concept for existing/occupied homes targeted at housing corporations and investors. 

Heijmans Horizon
Timber frame homes that Heijmans will build in its own factory in Heerenveen

Heijmans Huismerk
This is a concept home with a high level of standardisation, intended for the rental market, commissioned by housing corporations and investors. The production process is largely industrialised. Prefab sections are assembled at the building site. 

Heijmans ONE
These are moveable one-person homes for specific target groups that are poorly served in the current housing market, such as starters, people in urgent need of a home and refugees with residence permits. 

Huismerk Apartment Concept
An apartment concept jointly developed by Property development and Residential building for urban development or redevelopment areas. Faster development and construction should result in affordable apartments for various target groups in the social, mid-market and higher segments (both rental and owner-occupier).

IF figure
The Injury Frequency (IF) index figure is the number of accidents resulting in absenteeism that occur in a particular timeframe, divided by the number of work hours.

Integrated Reporting Framework
This is integrated reporting in which organisations indicate how sustainably they operate and how strategy, governance, performance and outlook deliver (social) value in the shorter and longer term.

Key performance indicators, or KPIs, are variables used to analyse the performance of companies. 

LEAN is a business methodology designed to increase efficiency. Application of the LEAN methodology is used primarily to develop flexible working practices, driven by customer demand and the maximum elimination of waste.

Nature-inclusive construction
Nature-inclusive construction is an approach – tailored to the area due to be developed - that combines the design of the construction project with the strengthening of the natural green areas. The aim is to create a healthy, future-proof living environment for both people and animals.

Near Energy Neutral Building (BENG) standard
Standardisation that sets criteria for the energy performance of a building and expresses this using three indicators: energy demand, primary energy use and share of renewable energy.

Porthos ruling
 Porthos is a collaboration between the Port of Rotterdam, Gasunie and EBN. Porthos is developing a project in which CO2 from the industry in the port of Rotterdam will be transported and stored in empty gas fields under the North Sea. In November 2022, the Council of State issued an interim ruling on Porthos’ use of the statutory construction exemption. This exemption means that no permit is required for nitrogen emissions that occur during project construction. The Council of State ruled that the construction exemption may not be used, as it cannot be ruled out that it could damage nature in Natura 2000 areas. This ruling has major implications for construction, infrastructure and sustainability projects in the Netherlands.

Procurement is the process of finding, agreeing on terms and acquiring goods, services or works from external parties.

Procurement spend

This is the application of smart technologies so buildings and areas can generate data that enables the more effective management of resources.

Smart grid
A smart electricity system that matches demand for electricity with supply at any given moment.
