Energy Efficient Buildings

TermoDeck® Buildings fulfill high requirements from an energy, environmental and thermal comfort perspective. Therefore, high ratings have been achieved by methods used for green buildings such as BREEAM, LEED, Passive House standard, Miljöbyggnad, etc.

  • In Sweden two residential projects have achieved the Passive House Requirements and more recently two other residential projects have been designed to achieve ”Miljöbyggnad Guld” criteria
  • In UK, a commercial building was awarded a BREEAM rating of 87.5% in 2007 which was the highest ever BREEAM rating at that time

The TermoDeck® System has been proven to have very low energy consumption in several countries. Why?

Large amounts of energy (heat or coolth) can be stored in the hollow core slabs of a TermoDeck® building and utilised later, which leads to very energy efficient buildings.

Therefore, the highest energy savings are achieved in cooling mode in commercial and institutional buildings with high and fluctuating internal loads that are stored in the slabs during daytime.

  • In cold and temperate climates passive cooling can be used during nights using mainly cold night air to cool the building. Very little cooling is needed during day time
  • In hot climates, where nights are often hot, off peak cooling is used by running the chiller (AC-system) both day and night. During the night, the efficiency (COP) of the chiller is higher as the outdoor temperature is lower than during day time. The supply air is circulated through the uilding during the night using no fresh air

In residential buildings the energy savings are smaller but there are examples showing that residential projects using the TermoDeck® system are also energy efficient buildings.

energy consumption in Scandinavia and UK

Operational experiences of existing TermoDeck® buildings in Scandinavia and UK show energy consumption for heating to be between 20 to 50 kWh/m2 per year.

Middle East

A report carried out in 2005 by ASA Consulting showed that TermoDeck® would save around 40% in running costs compared to conventional HVAC systems.

AC System Installation Cost (%) Operating Cost (%)
Conventional AC 100 100
Ice / Chilled Water Storage TES AC 185 106
TermoDeck TES AC 80 60

CO2 Emissions

The CO2 emissions are heavily reduced in TermoDeck® buildings since the energy consumption in new buildings is normally reduced by 10-30% compared to equivalent buildings with the same initial costs. This leads to large cumulative savings of CO2 during the building's life cycle. In older buildings the energy savings have been higher in many cases.

A report commissioned by British Offset concluded that the increased utilisation of TermoDeck® in Saudi Arabia would lead to estimated savings of CO2 emissions until 2020 of 18.2 million tonnes.

TermoDeck® System

TermoDeck differs from other energy saving systems because the overall construction cost is lower than conventional buildings as no extra equipment is added.

Thermal energy storage

Thermal energy storage (TES) systems can heavily reduce the installed cooling loads and peak power loads.

Energy efficient buildings

 TermoDeck® Buildings fulfill high requirements from an energy, enviromental and thermal comfort perspective.

Cost-efficient buildings

Independent reports have been carried out comparing capital costs of TermoDeck and conventional HVAC systems.
