With LSC, D+H offers a system for smoke exhaust and ventilation of lift shafts as a complete system, all from one source.
Up to now, lift shafts were often equipped with a permanent vent at the top of the shaft which supplied the lift shaft with fresh air and ensured that in case of fire smoke could escape unhindered.
These permanent vents represent a breach in the building's thermal insulation.
The result: Rising air in the shaft, caused by thermal effects (stack effect) draws the building's warm air through the joints of the shaft doors out of the corridors and rooms into the shaft. From there it can escape outside unhindered through the opening at the top of the shaft.
LSC prevents unnecessary energy loss as a permanent opening at the top of the shaft is avoided and therefore uncontrolled deairing of the building prevented.
The Energy Directive 2002/91/EG requires that in future all heat-transferring surfaces surrounding buildings must be constructed in a way that ensures that they are permanently airtight according to the latest technology.
LSC consists of a smoke detection system in conjunction with an electric motor driven smoke exhaust system and reliably ensures rapid smoke removal in case of fire. At the same time, unnecessary loss of heat within the building is avoided as the smoke exhaust opening at the top of the shaft is permanently closed and is only opened for smoke exhaust in the event of a fire.
The continuing high oil price as well as the generally rising energy costs are forcing operators and users to rethink. The D+H System LSC prevents unnecessary energy loss as it avoids a permanent opening at the top of the shaft and thus eliminates uncontrolled deairing of the building.
The result: The operating costs of the building are significantly reduced.
The optimised thermal insulation leads to better values in the energy performance certificate which is to be successively compiled for all buildings from 2006. This will have a positive effect on the image of the building.
This enhances the building's attractiveness for tenants due in no small measure to the lower utility costs. This in turn has a positive effect on the value of the building.
The closed smoke exhaust openings reduce the draught in the stairwell and consequently increase the thermal comfort for the user. In addition, any whistling sounds resulting from an excessively high air current are prevented.
