ECO-buildings |
ECO-buildings at Helsingør: In Helsingør,
improved energy efficiency is planned for demonstration in administration buildings, schools and institutions (in total 25,000 m2)
selected from a long-list of candidate buildings; and during the initial analysis, Prøvestenen, which houses the Social
Administration Office and Job Center of the Municipality, has been selected as one of the building complexes for demonstration of
energy efficiency measures.
The ECO-City project has also included new ECO-buildings at the Tretorn site at the northern side of the harbour, which will
be constructed during 2008-9.
Furthermore, it has been decided to include the ECO-City components in the large project called Kulturværftet, which will become
the new cultural centre in Helsingør including a theatre, exhibition areas, café etc. in a selected area of approx 9,500 m2 net.
The ambition of the ECO-City is to carry out the rehabilitation with a solar façade and several energy-efficiency actions. The
location is the most exposed in Helsingør at the harbour front just opposite Kronborg Castle.

ECO-buildings at Helsingborg: In Helsingborg, an analysis
of the planned building projects of Helsingborgshem has been carried out in 2006-7. COWI analysed alternative total ECO-energy concepts for
different building sites for new ECO-buildings in close collaboration with Helsingborgshem for both new ECO-buildings and ECO-rehabilitation
in close collaboration with Helsingborgshem.
A number of project sites have since been selected for ECO-City measures, including for instance Fronten in Helsingborg.

In the "Kvarteret Fronten 3" project in Helsingborg, a series of energy
efficiency and sustainability measures has been included in the design and construction of the building. The project consists of
50 new, relatively small, ECO-dwellings for elderly people distributed over 14 storeys. The main features to reduce the overall
energy demand include additional insulation (above current Building Regulations), low-e windows, heat recovery ventilation and
district heating.
The building is currently under construction and is expected to be finished in January 2008.
The Portalen project in Helsingborg consists of 107 new ECO-dwellings in a 6 to 7-storey building and is built to the same high energy efficiency standards as the Fronten project. Pre-fabrication, additional insulation, energy monitoring, low-e windows, heat recovery ventilation and district heating all help reduce the overall energy demand in this building. Further, 80 m2 of evacuated tube collectors will be installed at the façade and on the roof, thus delivering additional heating energy. The project is also currently under construction and is expected to be finished in March 2008.
Another part of the building is equipped with heat pumps for preparation of domestic hot water.
It will be compared whether solar collectors or heat pumps are the most suitable for preparation of hot water.

Parkkvarteret is also part of the ECO-City project, where 111 dwellings
in relatively old city apartment blocks to be ECO-rehabilitated and completed in phases 2007-2009. One block is presently
being renovated as a pilot for the whole project. The project includes introduction of balanced ventilation with heat recovery.

Also the Hamilton area in Helsingborg has been part of the project,
consisting of 140 dwellings in concrete apartment block from 1968 which is to be ECO-rehabilitated (approx. 14,400 m2) to
low-energy standard. A central heat pump plant and air heating are central elements in this project. Construction to be
carried out in 2007-2009.

Control management and metering

Helsingborgshem and Öresundskraft have worked with the development and improvement of the Comfort metering system and have been in current dialogue with COWI and the Norwegian partners.
The combined metering control and information system is to be integrated
and tested in the buildings of Portalen.

Training and campaigns |
Common workshops: Helsingør and Helsingborg have
worked together on a strategic training event, where stakeholders involved in energy efficiency campaigns created a network
and started up defining themes and a work procedure for energy savings campaigns towards end-user in the region.

Energiverkstaden: In Helsingborg, the buildings of a "City Farm", which were previously occupied by animals, have been refurbished to now host a new Energy Centre basically used for pupils. The so-called "Energiverkstaden" provides a series of outbuildings displays and training activities for school classes. The displays include a "Tree and Wood" section and small-scale building services systems consisting of a heat pump, a heat exchanger, and thermal solar and PV panels. This is a particularly nice example of how to bring the topics of "sustainability in buildings" in an exciting "hands-on" way closer to pupils. The Energiverkstaden is already open to school classes and welcome an average of 2 classes per week.

Renewable Energy Plans
|
Biomass boiler in Helsingør: The design and planning
of the biomass boiler has been carried out, and a conditioned contract has been signed.
Steffen Agger, the manager of the district heating company in Helsingør, is showing the ECO-City team the location of the coming
biomass boiler. The building comprised an old incineration plant. The building will be renovated as well.

Wind turbine: Öresundskraft has worked intensely with
investigation of possible wind turbine sites in Helsingborg and has identified a suitable area at the harbour for investigations
of geotechnical issues, noise and wind regime.
The wind turbine will be 2 MW and is planned to be constructed in 2009.

Polygeneration: Lund University has prepared a
hydro-geological documentation and prepared a report. The evaluation, which concerns different concepts for three identified areas
where a demonstration project can be implemented, is almost finalised. Öresundskraft has also been working with location of the
combi-cooling plant together with Lund University. IKEA is one possible option.
CONCERTO plus
In May 2007, the CONCERTO plus team was invited for a site visit in Helsingborg, at this picture visiting the ECO buildings of Türket.
