Hillerød, Denmark

In Hillerød, the regional capital of Denmark's North Seeland region, is showing that a zero CO2 community can become reality, with a development of more than 78,000 m² eco-houses that will exceed by at least a quarter of current energy efficiency standards.

The CONCERTO approach

A combination of a number of renewable sources will provide power for the settlement. Biomass will be burned to produce electricity and heat, with the biomass plant having 500kW heat capacity. There will also be a major investment in solar power, with the construction of the 3,000 m² solar thermal plant that will be connected to the district heating grid. A variety of other techniques will be used to complement the main renewable sources, including wind energy, PV capacity, heat pumps, and low-energy district lighting.

Around 670 houses in the new community will be Class 2 dwellings, meaning they go beyond mandated Danish standards by reducing heat energy demand by additional 25%. The Class 2 housing development will cover more than 72,000 m², and will include single family houses, row houses and high rise apartments and small industry. These will be accompanied by 6,500 m² of Class 1 apartments, meaning their heat energy demand is 50% below national standards. All housing will be well insulated, and will have other energy saving measures.

Importantly, a system for energy data collection of each house will be developed, with energy usage information collected in a central computer. In this way, the utility company can follow the individual consumption of each household and hence target energy advice.


Use of Renewable Energy Sources

•    CHP using Biomass
•    Solar Thermal Collectors
•    Photovoltaics
•    Wind energy


Low Carbon Technologies

•    Heat pumps
•    Low-energy district lighting
•    Insulation
•    Intelligent Energy Management System
•    District heating    


Highlights

Consumers will be able to monitor their consumption of both heat and electricity through an online graphical presentation available through the Internet, on their television, or via an energy meter. Additional data from weather forecasts and heat storage status will be available on the supply side, so that the utility can moderate its energy output accordingly.
