Energy efficient solutions are a pre-requisite to achieve Green Buildings status

The World Green Building Council and its regional satellite operations located around the world, set challenging targets to property owners intent on achieving the coveted Green Building status. Utilising a wide range of energy efficient solutions will help, but is generally not enough. What is needed is a holistic approach that considers all aspects of a buildings energy consumption, recovery and potentially generation. It is only by coordinating all aspects of the energy management strategy to create a fully integrated design solution, that Green Building status becomes a realistic objective.

Owners of buildings in a wide variety of market applications are turning to Fläkt Woods in an attempt to achieve this high profile accolade. With a list of references extending across Europe, the USA, the Middle East, Far East and Australia, the Group has a wide portfolio of solutions that can form part of a cohesive Green Building strategy. Look for the e3 logo throughout this website for details of products designed to deliver economic, energy-efficient solutions that are kind on the environment.

Examples of Fläkt Woods Products & Systems that can form part of Green Building Energy Management Strategy include:

Econet® Energy Recovery

The Econet® energy recovery system is a coil-based energy recovery system, providing class-leading levels of performance. Unlike most high-efficiency recovery systems, Econet® relies on heat transfer via water-filled coils. The two opposing air streams are therefore kept totally separate, ensuring that no contaminates can pass between the two.

Another key advantage of Econet® is that it a low-temperature system, which means that it is possible to use waste heat from a variety of sources to heat the incoming air. These can include ground source heat pumps or waste water from chillers or industrial processes. Heat recovery, heating and cooling are integrated into a common circuit, with coils, pumps, valves, pipe systems, insulation, etc. The result is a shorter and more compact ventilation unit.

3 Angstrom Wheel Technology

If even higher levels of energy recovery are required, then a thermal wheel may be the answer. Fläkt Woods offers a comprehensive range of single and twin wheel configurations for a wide variety of applications. In climates with high humidity levels, such as the Far East, a Desiccant Wheel can provide an ideal solution. By transferring moisture as well as heat, the product can provide both humidity and temperature transfer, providing very substantial savings in energy consumption.

Fears of contaminant cross-over have deterred many designers from using this concept in Hygiene applications where the exhaust air may be contaminated. However, Fläkt Woods has the solution.

SEMCO has been producing and refining a unique 3-angstrom wheel technology for 20 years and was the first company worldwide to address the problem of desiccant carry-over. The firm’s patented 3A molecular sieve coating has been proven to limit contaminant carry-over in laboratory testing as well as in numerous field studies over many years.

Chilled Beams

Chilled Beams are now widely recognised as one of the most energy efficient methods of controlling the air climate in buildings. Traditionally however, they have been criticised for lacking the flexibility to cope with the increasingly frequent changes of use and layout that occur in today’s typical office environment.

The launch of Fläkt Woods’ Astra Integrated Beam from the IQ Star® range provides a perfect solution to this dilemma. The product includes a unique combination of a “Boost Function”, allowing air volumes to be adjusted to reflect changing CO2 levels in the various zones, and “Flow Pattern Control”, providing the ability to direct air in various directions from one or both sides of the beam. The Boost Function ensures that only the necessary amount of treated air and cooling capacity is provided, avoiding significant waste, whilst the Flow Pattern Control maintains the efficiency of the air distribution regardless of changes to the layout of the space.

This combination of features provides a perfect solution for Green Buildings; minimising energy consumption and maintaining good air quality, whilst accommodating any required changes to the use of the building.

In a typical large, modern commercial building, the initial capital investment will represent only 15% of the lifetime cost of the building, with HVAC only representing a small proportion of this. Of far greater importance is energy consumption, which typically accounts for a massive 80% of the total running cost for the building. Effective heat recovery, highly efficient fans and innovations such as Free-Cooling Chillers provide substantial opportunities for cost savings. A combination of these, forming part of an integrated system, can help to deliver Green Building status at a remarkably low cost.

Unlike most suppliers of HVAC systems, Fläkt Woods manufactures the majority of key sub-systems in-house, including thermal wheels, fans and structural assemblies. By selecting an integrated Fläkt Woods System, you can be sure that the combination of components will have been optimised for maximum overall efficiency. By taking a holistic view, substantial savings in capital and running costs can be achieved.
