Healthy environment

More efficient energy consumption, fossil-free energy sources and sound material selections are all important components in terms of minimizing our impact on the environment.

Lower climate impact and energy consumption

Energy consumption impacts the climate

Production of electricity and heat causes a great deal of the greenhouse gas emissions that impact the earth's climate. The construction industry uses a great deal of energy – approximately 30 percent of Sweden's total consumption (according to the National Board of Housing, Building and Planning) – and energy consumption is thus the most crucial environmental impact issue faced by the industry. During the building's entire life cycle – from production to demolition – the greatest amount of energy is utilized during the long usage phase (operational phase). It is therefore important to minimize the energy requirements of buildings.

Energy consumption during the production phase

JM also works proactively to reduce energy consumption during the production phase. Only eco-electricity is purchased in Sweden (Bra Miljöval – Good Environmental Choice). All work sites have energy-efficient sheds and low-energy lighting with light and motion detectors, and energy consumption can be further reduced by using early startup of district heating to heat the building frames during construction.

Reduced energy requirements

In order to ensure low energy requirements in JM's buildings, a high level of energy efficiency is planned as early as the drawing table. Direct electrical heating was prohibited in all buildings as far back as 1999. Energy-efficient appliances and fans have also been mandatory for many years. Requirements for especially well-insulated windows were introduced in 2005, and from 2007 all of the buildings have been designed to include hydronic heating systems

All of JM's residential units have been built in low-energy buildings since 2008. All residential project development that JM has initiated in Sweden since 2008 has been based on JM's low-energy housing concept. Low-energy buildings are buildings that meet the authorities' energy requirements during operation by a substantial margin. JM's low-energy buildings have, for example, extra insulation in the walls, energy-efficient windows, energy-efficient appliances and low energy lighting, and they recover heat from ventilation and have individual hot water meters. We improve the energy performance of our buildings on an annual basis through a number of measures, and we aim to be the leader in building low-energy buildings in all of our projects – not just individual pilot projects.

Climate-efficient transportation

Construction machinery and transport of goods and people are responsible for considerable emissions of substances that impact health and the environment. JM procures the majority of goods transportation and work requiring heavy machinery from suppliers. To a large extent, subcontractors take care of JM's transportation needs and work that is performed with heavy machinery. By developing our logistics processes in relation to these subcontractors, we hope to be able to reduce the environmental impact significantly. In the agreements we sign with transportation companies under which we purchase transportation services ourselves, we are gradually introducing more in-depth work environment, safety and environmental requirements in accordance with the Swedish Transport Administration's Qlll system.

Impact of materials on health and the environment

Sound materials

The problem posed by the increased usage of chemicals in society is growing. JM's residential units are built using sound, proven and natural materials such as tile and wood. Since the mid-1990s, we have had an environmental assessment system in place in order to steer the use of building materials toward reduced usage of chemicals and reduced burden on the environment. Our materials must not cause our customers or our employees to become ill, and their impact on the environment must be minimized.

Energy ratings of homes

 JM applies a system for rating energy in residential units – an initiative that benefits our customers. The energy rating system is similar to the one used for major appliances, and it indicates a residential unit's energy consumption. The system is based on Swedish Standard SS-24300 and JM's guidelines. In addition to customer benefit, the energy rating also provides JM with increased understanding of the energy consumption in our residential units. With JM's low-energy housing concept, we have laid the groundwork for an energy-efficient building, but the buildings' energy consumption will nevertheless vary depending on the inhabitants' behavior, the design of the energy system and where in the country the building has been built.

How we calculated (see our Guidelines for Rating Energy in Residential Units)

Examples of measures within the field of transportation

  • we place demands on the fuel that suppliers use – alkylate-based fuel is to be used in small gasoline-driven machines
  • we place demands on age, Euro class and maximum allowed greenhouse gas emissions from the vehicles, and suppliers must be able to demonstrate that they follow up on their fuel consumption and that they take measures to decrease their consumption
  • we test and assess consolidated shipments of materials, degree of utilization in trucks and the right type of delivery vehicle to the work sites
  • In the agreements JM signs with transportation companies, we have implemented stricter requirements that are in line with the Qlll system, a tool that was specially designed by the Swedish Transport Administration. The aim is to become a better purchaser of transportation as regards work environment, road safety and the outer environment.
  • Business trips for JM must be conducted so that impact on the environment is minimized as regards carbon dioxide emissions.
  • all company cars are green cars (as defined in the Road Traffic Tax Act)
  • train travel is prioritized over air travel, and public transit is encouraged
  • JM offsets carbon emissions from air travel (via Plan Vivo)
  • videoconferencing equipment at the offices reduces the number of business trips.
