Setting high aims for lower energy consumption

AF Bostäder works intensively to reduce energy consumption. The focus is on properties built before 2009 and the aim is a 15 % reduction in energy consumption among the older properties in the portfolio by 2019.

AF Bostäder’s newly-built properties are constructed with a requirement that they will use 15 % less energy than the National Board of Housing, Building and Planning’s requirement. Whereas AF Bostäder’s new construction requirement is 64 kWh per m2, the older properties can use as much as 195 kWh per m2, which explains why these properties are the top priority.

“We have run a project at Kämnärsrätten since 2015 in which we measure the room temperature in 25 % of the apartments,” says Staffan Jacobsson, Technical Services Manager at AF Bostäder. “The average temperature of the apartments then automatically controls the heat flow temperature to the radiators. This method reduces energy consumption. Technical upgrades, such as replacing fans and pumps with more energy-efficient upgrades also makes a considerable difference. All our buildings are now computerised and connected via built-in, fully graphical web servers, which gives us the possibility to optimise the operation of our heating and ventilation systems. We have everything monitored in real time, 24/7.”

AF Bostäder has also installed a new geo-energy unit in one of the properties at Kämnärsrätten. The unit consists of two heat pumps and 14 energy wells, which take heat energy from a depth of 250 metres below ground.

“The unit covers almost the whole building’s heating requirements,” says Staffan Jacobsson. “Compared with electrical energy, we obtain four times as much heat energy using geo-energy. The unit is a considerable investment, but provides a total saving of SEK 8.5 million over the unit’s depreciation period.”

AF Bostäder renovated 12 apartments at Studentlyckan in 2017.

“Among other things, we have replaced the older natural ventilation with modern kitchen fans,” states Staffan Jacobsson. “The fans contain FTX units, which ensure that the warm room air heats up the fresh air from outside to 18 degrees. This provides about 80 % energy recovery.”

Ever since the early 2000s, AF Bostäder has conducted various water-saving projects including the installation of low-flow taps and shower hoses. AF Bostäder has also replaced the adjustment valves for hot water circulation in almost 500 apartments at Kämnärsrätten, so that hot water is supplied immediately, without having to run cold water through taps or shower hoses first.

“An important complement to our efforts is to engage our tenants. We have, for example, produced a film called Värmeresan (Heat Flow). The film covers areas such as how to air a room, how to furnish a room to avoid blocking the heat flow and why you should never close your ventilation when you are cold,” says Staffan Jacobsson.

Three years have passed since the target for increasing energy efficiency was set, and so far AF Bostäder has reduced the energy consumption in its older properties by 6 %.

Ulrikedal gets the best conceivable outdoor life

In a two-year initiative, AF Bostäder has renovated and renewed the outdoor environment at Ulrikedal. In addition to technical maintenance and improved waste systems, the initiative has given the students secure, well-lit bicycle parking spaces, pleasant areas for socialising where lawns and meadows are interspersed with barbecue areas, boule court, outdoor gym and much more.

Strong focus on indirect emissions in scope 3

AF Bostäder has achieved good results in measuring and reducing emissions of greenhouse gases in its own operations and from purchased energy. Now, the focus is intensifying on other indirect emissions. A recent review is to form the basis for reducing emissions from new construction projects and property management.

Sedum and meadows promote biodiversity

One of AF Bostäder’s prioritised global goals concerns protecting biodiversity and natural living environments. AF Bostäder promotes a great variety of species by means such as confining new construction to areas with already impervious surfaces and laying sedum roofs. Much remains to be done and several new initiatives are under way.

Success for the recycling shelves!

The students can hand in waste such as batteries, electronic devices, light sources and bulky furniture in the Green Room, which also has the popular recycling shelf where objects disappear just as fast as they are handed in.

Emissions target for building projects

Since 2020, AF Bostäder has carried out climate impact calculations for all new construction projects, something that will be required by law from 2022. The aim is to map and reduce the impact of new construction on the climate.

Fat collection fuels emissions reduction!

Cooking fat that is disposed of in the kitchen sink can cause damage to drains and sewers and attract pests, but if the fat is collected, it can be converted into biofuel. In a pilot project, the students have recycled a total of 700 kilos of cooking fat, and the initiative is now being expanded.

Ash deals with cigarette butts!

Most of us know that cigarette butts should not be discarded on the ground or in nature, but even so they tend to end up there. With a newly started nudging project at Delphi, AF Bostäder wants to inspire more people to dispose of their cigarette butts in the correct way, for the benefit of wellbeing and the environment. At the heart of the project is AF Bostäder’s newly engaged staff member: Ash.

Green Room inspires reuse

AF Bostäder’s bulky waste stations have been given a new design to inspire the students to minimise their waste, increase their recycling and find satisfaction in reuse. Say hello to the Green Room!

Continuing challenge to be 100% fossil fuel-free

In 2016, AF Bostäder decided to be 100% fossil fuel-free in terms of electricity, heating, transport and equipment by the end of 2020. A minor volume of fossil fuels is still used, but emissions have been reduced by 92%. Over the next five years, the focus will be on indirect emissions – an area in which the company has the greatest possibility to exert an influence.

Improving the living environment with underground recycling

Area by area, AF Bostäder is replacing all its waste stations with Underground Waste Systems (UWSs). Initially, it entails a considerable investment, but there are many benefits in the long term. Waste sorting increases, waste management becomes more cost-effective and above all the students get a living environment that is clean, tidy and secure.

Successful textile collection

In Sweden we are good at waste sorting, but only about 20% of clothing is recycled – something AF Bostäder wants to improve. Between 2015 and 2020, the students have collected 130 tons of textiles in easily accessible containers from Human Bridge.

Halved heat consumption

We continue to optimize energy use in the older property portfolio. That's why we installed our first geothermal plant at Kämnärsrätten - and halved the property's heat consumption.
