Site, Architecture & Energy
The European Spallation Source will be one of the most advanced science infrastructure projects ever built. The architecture and design of ESS should reflect and contribute to the organisation’s core values: excellence, collaboration, openness and sustainability.
The ESS site is located in a highly developed scientific and industrial environment, providing access to an educated and technically-skilled workforce, and with proximity to Lund University and other major research centres.
The ESS complex will greatly influence the visual impact of the area as the site is prominently placed on a ridge of gently sloping hills between 74 and 82 meters above sea level.
The ESS facility is being built on a 74.2-hectare site in the northeast outskirts of the Brunnshög district of the city of Lund, in close proximity to the MAX IV synchrotron.
ESS and Max IV construction plans call for an area between the two facilities, the “Science Village”, which will include shared infrastructure and services. The Brunnshög district is currently undergoing extensive growth and development. A mixed-use neighbourhood is being planned, with around 3,000 dwellings and businesses providing employment for 20-25,000 individuals by 2025.
Previous archaeological excavations made in the farmland north of Lund, where the ESS construction site is located, detected early settlements indicating that the area has been populated for millennia.
An extensive programme of archaeological investigations was carried out prior to construction by a team of archaeologists managed by the Swedish National Heritage Board (Riksantikvarieämbetet).
Antiquity Meets the Future—Archaeology at the ESS Site was published in 2015 to accompany an exhibit of the findings at the Lund Historical Museum.
Landscaping and urban planning of the ESS site requires the same level of careful attention as the design of buildings.
As the facility stretches out over almost 1 km2 of land and the chosen site is on a ridge rising above the surrounding landscape, ESS will direct particular attention towards layout of the site, flexible development, transportation within the site, with an eye toward views of the site from neighbouring locations. The challenges and unpredictability of the Scandinavian climate during winter will be taken into account, and the effects minimized, when planning the landscape design. ESS will promote biodiversity in the area as the site neighbours parkland and the typical rural landscape of the Scania region of southern Sweden.
Terracing for the accelerator, target, and instruments will be carried out to accomplish a common ground level, balancing the masses within the designated area, which minimizes the need for transport of soil. Use of storm water ponds and open ditches will create a pleasant and natural outdoor environment. Trees, bushes, and other landscaping elements will contribute to the goal of a soft and green environment around the facility and connect it with the surrounding farmland.
A system of roads and pathways is planned around the buildings to facilitate transport and access for various types of traffic across the site, including heavy transport, bicycles, and pedestrians.
Sustainability is an important factor when planning the road structure, therefore pedestrians and bicyclists will be given priority over car traffic.
When planning the parking requirements for the facility, the fact that ESS will be frequently visited by many guest researchers has been taken into consideration. Landings sufficient for loading and unloading heavy goods at the loading bays are required. Bicycle parking facilities are planned and will be located near entrances with good lighting and weather protection.
As part of the ESS “zero impact vision”, where the goal is to avoid emitting any pollutants into the environment, a system for treating polluted storm water will be designed.
The goal will be to clean the water in such a way that the storm water running back to the natural streams will not deteriorate the environmental status of the stream or its surroundings. To avoid an overload of existing drainage systems, the storm water flow from the development site will be collected, through pipes and open systems, in detention ponds with regulated outlets. There will be a closing device on the detention ponds in order to facilitate sample-taking, treatment, and disposal of polluted storm water.
Many of the buildings at ESS will be technical utility buildings of an industrial nature, which imposes limits and challenges for the architectural design. The architectural conceptualization of the buildings is vital for the visual impact of the facility and for the integration into the surrounding landscape and neighbouring Science Village.
After an international design contest held in 2012, and a following negotiated procedure, Team Henning Larsen Architects was chosen to develop the overall architectural concept. The contest jury’s motivation was the following:
The proposal shows great skill and sensitivity in creating in-between spaces and a strong urban context. There is a strength in the campus concept and the possibility to achieve differentiation and variation in buildings and places. The link to Science Village is a clearly expressed theme well developed in the proposal. There is a human scale represented as well as a dramatic scale in the roof structure.
The architectural strategy is based on three layers of design:
The central element of the spallation process, the Tungsten target wheel, is used as inspiration for the roof of the Target Station and Experimental Halls, in order to create one coherent image of ESS.
The second layer of design materialises in the campus layout allowing for growth and change.
The European Spallation Source (ESS) will be the world’s first sustainable research facility. One of the major challenges to accomplish this will be the facility’s energy consumption and costs related to it. ESS's Responsible, Renewable, Recyclable energy concept is the primary tool for realising this goal.
ESS is a long-term commitment that will benefit coming generations and contribute to managing global environmental challenges both by scientific results and by how the facility itself is built and operated.
Setting a new standard for how research infrastructures are managed over their lifecycle is an important development for the future.
The main purpose of Responsible is to monitor the estimated electricity consumption of ESS so it stays below the committed 270 GWh and to predict future energy related operations costs for the possibility to lower these as much as possible for the benefit of science.
Systematic energy management involves creating and maintaining an inventory of energy flows, including temperature levels. Together with system audits, this will be the base for an Energy Management System consisting of a policy, follow-up and reporting.
The cyclic energy inventory and audits encourages and maintains continuous dialogue between the energy group and all the other projects, thus promoting a strong energy culture at ESS.
The amount of electricity required for the operation of ESS corresponds to the annual output from 30-40 wind turbines (around 270 GWh/year). This is about as much as the annual consumption of 40 000 apartments or of a small Swedish municipality.
When ESS is fully commissioned, the power consumption in Lund will rise by 20-30%. The extra load on the Nordic power system would require power compensation from what is referred to as marginal production that currently emanates, to a substantial degree, from fossil fuels. That is not acceptable according to the energy policy of ESS.
When it comes to the supply of electricity to the facility, ESS has two main policies:
ESS is committed to renewable power production to compensate for the increased power consumption caused by ESS
It is vital for research operations that the cost of electricity for running the facility is competitive, stable and predictable
The first and second policies together imply that ESS cannot just buy electricity from an existing power source. The renewable promise combined with low cost, stability and predictability makes it necessary for ESS to initiate production of new renewable production facilities to compensate for its power consumption.
The second policy has to do with operation costs—establishing a well-designed solution for the power supply to ESS will serve as financial cushion and risk mitigation. By having a partnership with an external party in a way that resembles ownership will make a considerable contribution to channel scarce funds to the main purpose, i.e., research.
ESS is committed to not only recycle the surplus energy from its operations but also do it under a scope that is responsible. The total amount of surplus energy is estimated to 254 GWh annually and consists of hot water that is a result of the cooling process in the facility.
In order to optimise heat recovery efficiency, the cooling system is calculated to operate at three temperature levels: 30 °C, 55 °C and 80 °C where the high-temperature waste heat can be transferred and recycled directly into a district heating network. The lower temperatures are suitable to be utilized in food production systems.
For the medium and low temperatures of waste energy ESS holds a unique possibility to set a new standard on how to recycle energy and are in the process of developing a so called hybrid food production chain that can utilize the energy in commercial food production such as fish farming, green house production, feed protein production, micro algae and biogas.
A successful development would certainly connect ESS with its environment in an unexpected, although natural, way and contribute to a social and economic sustainability that goes beyond the walls of the facility.
