Low Energy HVAC System

TermoDeck Cooling, heating and lighting buildings uses as much as 40% of the world’s energy. In warmer climates, blasting air conditioning on hot days is a huge problem, leading to power shortages at peak demand and productivity losses when people cannot work effectively.

Today, the solution is spare generators, often run on dirty fuels which produce high emissions of CO2 and other gases. In addition, large investments must continually be made in the power sector to cope with rising peak demand, though peaks are only 5% of the entire annual demand.

There’s a better way. TermoDeck is a low-energy HVAC system which adds thermal energy storage into new building structures. TermoDeck’s energy storage technology added to concrete floor slabs can translate to 20-50% less energy for heating and cooling, and a 70-90% reduction in peak cooling loads.

By replacing traditional steel ducts with hollow core floor slabs, TermoDeck taps the thermal storage capacity of almost any building – offices, hotels, hospitals, schools – to regulate internal temperatures. TermoDeck’s special method of using the concrete floor slabs with their hollow centers make then work as mini heat exchangers, warming or cooling air before it enters rooms.

TermoDeck has been proven in all types of global climates (cold, temperate, hot and dry, hot and humid) and views the market for their product as world wide. This smart technology, which stores energy right in a building, has huge potential to cut on site energy.

If this energy storage technology were used in one out of ten newly-built buildings from 2010, it would reduce CO2 emissions by 114 million tonnes per year by 2020.*

TermoDeck will continue to improve upon a control system for stored energy as well as increasing the ability of hollowed slabs to store thermal energy. In order to create an even more energy-efficient building, TermoDeck can be combined with other types of systems (such as PVs, solar panels, absorption chillers, smart diffusers, solar shading, etc). A test project with ClimateWell is in the works, while co-operation with other companies for comprehensive solutions is planned.

At the moment TermoDeck is raising funds in order to take advantage of an increased interest in energy storage technology. More employees are necessary as our small team is unable to handle opportunities that exist today let alone planned expansion in Europe, the Middle East and Asia.
Barriers and challenges
So far the major barrier for TermoDeck technology is conservatism within the construction industry, especially among mechanical consultants who are often reluctant to try new systems that they don’t fully understand. The bright side is new building regulations (especially in the EU) which demand reduced energy consumption in new buildings and thus new solutions. There is also a great interest among architects and developers to design energy-efficient buildings.

One of the company’s main challenges will be to find new partners in strategic markets. These partners will then need training and support, as well as help in promoting TermoDeck.

TermoDeck was invented by Loa Andersson (he is currently Technical Director) and the late Engelbrekt Isfält. For nearly a decade, Andersson worked for AxRo Consult in Stockholm while simultaneously developing the TermoDeck system. From 1977, Strängbetong has sold the TermDeck system in Sweden.

Together with John Durham, TermoDeck was introduced in the Middle East in 1990, and in the UK in 1993. Since 1995, the UK is TermoDeck’s biggest market. A separate company operating only in the UK was formed in 1998, and a license was sold to Tarmac.

To gather all the resources, income and IP in one company, TermoDeck International Ltd (TDI) was formed in 2003. TDI has global rights to TermoDeck technology, with the exception of Sweden where Strängbetong holds these rights.
