Underground Cold Storage for Hybrid Cooling of Buildings
The SoilCool/Rekyl project aims at supporting further exploitation of
Underground Thermal Energy Storage in the Nordic as well as European countries.
The project brings together important actors to collect and exchange experience
and disseminate this in a simplified way to increase awareness at design
consultants, investors, building owners and authorities.
The goals are to enhance the design of cooling systems, which can reduce the
energy consumption and CO2 emission related to cooling by 75-80%, integrate use
of district heating and renewable energy for cooling and use of re-cooling
energy for heating purposes using heat pump applications.
The project has been supported by EU SAVE Programme, project ref. no.
4.1031/Z/02-102/2002 and Nordic Energy Research Programme, project ref. no.

Background:
Energy consumption related to cooling of office buildings in Northern & Central
Europe has increased over recent years.
The architecture with large glazed facades, high use of IT-equipment and high
comfort demands have made it necessary to provide active cooling in typical
three to five months of the year. Energy consumption to meet this demand can be
reduced substantially and economically by use of underground cold storage and
use of energy efficient cooling systems in the buildings (high temperature
cooling). The cold storage technology invites for extended use of renewable
energy sources and improved energy efficiency. Therefore these systems are worth
to consider to comply with intensions of the Energy Performance in Buildings -
Directive 2002/91/EC.
