The Passive House Institute encourages using material, software and design concepts that reduce energy consumption and improve the thermal performance of buildings.\u00a0 There are several ways the doors and hardware specified for a building can help achieve these goals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Exterior door openings are a target for thermal transfer.\u00a0 They are, after all, holes in the wall. But not all doors are created equal when it comes to energy efficiency.\u00a0 An insulated door significantly reduces thermal transfer<\/strong> between the interior and exterior of a building.\u00a0 Look for polystyrene or polyisocyanurate insulation,\u00a0 or specific brands, like Trio-E from ASSA Abloy<\/a><\/span>.<\/p>

And don\u2019t forget about the frames.\u00a0 Exterior steel frames are normally back-filled with grout, so they help prevent thermal transfer in a different way.\u00a0 By making the frame out of two separate pieces and connecting them with non-conductive material, energy transfer from one side to the other is prevented.\u00a0 This is referred to as a thermally broken frame<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Another consideration for thermal performance is making sure the door closes properly and has an airtight seal around its perimeter.\u00a0 After all, an insulated door won\u2019t do much good if it\u2019s open or drafty.<\/p>

Selecting the appropriate door closer is a first step.\u00a0 Factors to think about are the size and weight of the door, its frequency of use and how the closer will be mounted.\u00a0 There are tons of options out there.<\/p>

The next step – closer adjustment \u2013 deserves equal attention.\u00a0 Closers on exterior openings need routine adjustments and maintenance to ensure they close properly.\u00a0 Stack pressure, seasonal changes to HVAC systems and simple wear and tear can all affect the closer.\u00a0 Inspect and adjust exterior closers every few months to ensure the door closes completely without slamming or being difficult to open.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Automatic door operators require the same consideration for specs and adjustments. Some operators, like the SW200i from Besam, have controls that can sense whether extra closing force is required to close and latch the door.\u00a0 They automatically apply some extra power to get the job done.<\/p>

Once the door closer is working properly, it\u2019s time to seal the gap between the door and frame to prevent thermal transfer.\u00a0 We have separate article dedicated to sealing drafty doors \u2013 read it here<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

From security devices to automatic door operators, electrified hardware is being specified more than ever.\u00a0<\/p>

Selecting the most energy efficient products can greatly reduce a building\u2019s overall consumption.<\/strong><\/p>

Most hardware manufacturers recognize this and design products with efficiency in mind.\u00a0 Some electrified devices use Power over Ethernet (PoE), meaning they can use a building\u2019s network cabling for power. This eliminates the need for a separate power supply.\u00a0 In the case of integrated cardreader locksets, the network cable is used to transfer data to the security system as well.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Other devices, like electric strikes, electrified exit devices and electrified mortise locks are being redesigned from their traditional power configurations.\u00a0 Some are retooled so they only draw power when activating, or so that they can activate with far less voltage. Sargent\u2019s EcoFlex\u2122 mortise locks claim to consume 96% less energy than traditional solenoid electrified locks.\u00a0 You can imagine the impact this could have in a large building.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

For the hospitality and\u00a0 student residence sectors, Salto’s aptly named Energy Saving Device (ESD) controls the electrical consumption in a room.<\/strong><\/p>

The user must insert their access card (the same one they use for the door) into the ESD in order to switch on the lights and other designated electrical equipment.\u00a0 When the occupant leaves and removes their card, the light and power shut off, prevention power form being wasted in empty rooms.<\/p>

The system can even distinguish between guest cards and housekeeping cards<\/strong>, only allowing maintenance staff to use the electrical devices they need to do their work.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
