Castellum’s efforts to reduce the company’s climate impact are
ambitious, and are in progress throughout operations. Working
efficiently to develop a more sustainable property portfolio has
been a goal of the company since the mid-1990s. This work has
yielded results, and Castellum is now among the most sustainable
companies in the industry.
To future-proof Castellum’s property portfolio and attain the global sustainability goals established by the UN and prioritized by the company, several challenging goals have been set. Buildings must be more energy-efficient, natural resources must be more efficiently utilized, biodiversity in urban environment must be increased, renewable energy must be improved and changing weather conditions must be taken into account.
Castellum is involved in the climate plans and policies of its customers and of government agencies. It supports international treaties such as the Paris Agreement, displays leadership and to the greatest extent possible influences the industry to reduce its climate
impact. For example, Castellum was the first property company to sign the Swedish government’s “Fossil Free Sweden” initiative, and also works actively with industry organizations such as the Sweden Green Building Council to develop environmental certification systems and the national initiative to create more sustainable buildings.
Castellum is also the first property company in the Nordic region to have its climate targets approved by the Science Based Targets (SBT) initiative. Castellum’s target is to achieve 100% climate neutrality in its operations by 2030, thereby supporting the UN’s climate agreement and the national ambition for a fossil fuel-free Sweden.
More efficient energy use
Castellum works continuously to reduce energy use by optimizing operations and investing in energy-efficient technologies. Over the past year, 93 developments comprising MSEK 73 were implemented, of which MSEK 5 pertained to investments in solar
cells (6 facilities) for the purpose of enhancing efficiency. Energy use within the Group is systematically monitored and then
analyzed in follow-up systems. The measures implemented are prioritized in order of greatest potential for enhancing efficiency.
Expansion is underway for Castellum’s own portal for webbased property monitoring, to check values for operations,
alarms, elevators and entries. This project saves energy and time, and simultaneously provides customer benefits in the form of better services through preventive measures. At present, 304 properties representing 2,213 thousand square meters are connected to the portal.
In 2018, the normalized energy consumption for heating and
property electricity in the comparable portfolio (like-for-like) increased
3% year-on-year. The increase is due to the challenging
weather conditions in 2018: a long, cold winter with increased
need for heating and an extremely
warm summer that involved
extra air conditioning. Another contributing factor was that over time it was not possible to maintain the full effect of 6% conservation, attained the preceding year, in property management. Heating
use increased 1% in 2018, while electricity use increased 4%. Since 2007, energy consumption has decreased by a total of 28% per square meter. Castellum’s heating consumption of 64 kWh per square meter can be compared with the industry average according to the Swedish Energy Agency’s reference value for heating premises of 122 kWh per square meter. This means Castellum’s buildings are 47% more energy efficient than the Swedish
average for these premises.
