To create an efficient automatic entrance, start by looking for a solution that meets footfall and other efficiency requirements of the facility. Then optimize thermal transmittance and sealing.

This was the advice given by ASSA ABLOY Entrance Systems' specialists, who were the subject of an editorial in the trade journal and magazine, Building Products, in January 2016.

Making sure that the optimal door solution is specified is vital to ensure that exits and entrances to any building of any size or function are as efficient as possible.

The quantity of footfall, but also the type and at which times the facility may experience an influx are important data to consider to have a true picture of the solution needed. Doors can be programmed to operate according to the peaks, opening for longer than at quieter times, when you understand the traffic patterns of both people and goods.

Revolving doors are often seen as the ultimate energy saving solution, providing an 'always open, always closed' entrancehowever they are not always feasible. Automatic single and bi-parting sliding doors are also highly functional entrances for heavy traffic areas. Sliding entrances can be thermally optimized, with bi-directional sensors to reduce 'stand open' times, telescopic opening, air curtains and tight-seals around leaves and fixed screens they create a thermally sealed external entrance. 

Optimal efficiency

The quality of the install affects operational and not least the energy efficiency. Tight sealing is a priority and site surveys to measure clear detailing of the frames/surfaces door systems will be fixed to, and post-installation quality checks to identify snagging issues quickly, are vital.

Remember the back door entrance

Equal weighting should be placed on working, intermediate and public-facing entrances, and all should be considered carefully. For example, large delivery doors at the back of a retail store, standing open for long periods of time could have as much impact on energy performance as smaller pedestrian entrances.

In delivery areas, high-speed doors which only activate when sensors detect a vehicle approaching helps reduce energy loss. For larger sites and distribution centers, dock shelters further improve both energy efficiency and working conditions.

Considering all factors for the front, back and interior entrances creates optimum operational and energy efficiency in a building, without compromising comfortable, flexible and safe access for staff, visitors and deliveries.
