Low Carbon Demo House Built with H+H

The H+H Thin Joint system with large format Jumbo Bloks has been used in the construction of a low carbon home deigned to meet level 5 of the Code for Sustainable Homes. Town and Country Housing Group (TCHG) in Kent constructed the prototype home to act as a test bed for building to level 5.

The house is designed to be as energy efficient as possible to reduce running costs for the occupants. A fabric first approach means the building structure is constructed to be airtight and thermally efficient to reduce heat loss to a minimum; using Thin Jointed aircrete significantly contributed to this way of building.

Paul White, design and quality manager, TCHG said: 'We used H+H aircrete blocks for the project for their high recycled content as well as their inherently high insulative qualities'. 'This allowed us to construct thinner external walls than alternatives on a tight site whilst still achieving a low U-value'.

He added: 'Using the Thin Joint system with the Ra Build method is a good option because speed of construction means the inner shell can be made weather tight extremely quickly, faster than using traditional masonry techniques thus preventing the structure becoming damp in wet weather and allowing other trades to start internal work earlier'.

'Furthermore, the system offers some thermal mass (to help regulate the temperature in hot weather) over and above standard timber frame options', Paul concluded.

The home is designed to fit in with others in the area and costs GBP205,000 to build - including the renewable energy technology that was being trialled - on land already owned by the housing group.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
