Dynamic Roof SDR [Standing Seam]

Dynamic Roof SDR products are designed for use in commercial or residential roofs

The 240mm deep roof systems reduce a 0.21W/m²K static U-value by up to 80% to 0.05W/m²K with the resultant reductions in space heating costs.

Dynamic Insulation in Commercial Buildings

In most commercial buildings the dominant energy user is air conditioning to cool internal heat arising from lights, equipment and occupancy. Insulation products that limit heat loss from the building envelope are therefore less applicable. 

A building envelope that can retain heat when required and then switch performance to dissipate incidental heat gain when required can transform the energy efficiency of Commercial Buildings and lead to much smarter carbon reductions. 

Energyflo's Dynamic Insulation technology is capable of both retaining and dissipating heat and therefore has the potential to improve the energy efficiency of Commercial Building envelopes.

Results have shown that Dynamic Insulation technology allows the building fabric to adapt to meet the thermal comfort needs of the building in the most carbon efficient manner. In a typical UK office, built to BCO guidelines, applying a dynamically adaptive roof system will result in CO² savings of circa 20% compared to a roof with U value of 0.1W/m².K.

The application of Dynamic Insulation creates a building fabric that is able to adapt to the transient energy requirements of the building. The fabric can now act as a blanket to keep heat in and take advantage of solar gains, and act as a sieve to permit heat to escape from the building whilst minimising solar ingress. It thus enables builders and designers to meet today's ever-increasing requirement for low carbon thermal comfort.  

Dynamic Insulation is a simple building fabric solution that converts the building fabric into a heat exchanger.  The heat contained in the air can be directed:

1. into the building to reduce heating load and / or 
2. away from the building to reduce cooling load.

Three Modes of Operation are possible when the dynamically insulated fabric is coupled to the mechanical ventilation system. For each mode of operation, it is possible to vary the air speed through the building fabric. Varying the air speed varies the heat recovery process allowing additional flexibility in fabric heat transfer processes to be achieved.

• Mode 1: Dynamic Heat Recovery - Dynamic Insulation recovers heat through conductive loss through the roof and from incidental solar gain. The air passing thorough the building envelope is entrained into the building offsetting ventilation conductance load. Equivalent roof U-value of 0.05W/m^2.K is possible
• Mode 2: Dynamic Heat Dissipation - Dynamic Insulation recovers heat through conductive loss through the roof and from incidental solar gain. This heat is unwanted and is contributing to a cooling load. The air passing thorough the building envelope is exhausted from the building offsetting the cooling load. Equivalent roof U-value of 1.0W/m².K is possible.
• Mode 3: Static Mode No air is moving through the building fabric. The fabric reverts to its ‘static’ U-value of circa 0.20W/m².K. This mode of operation is particularly useful as night time operation in buildings with internally driven cooling loads.
