PRODUCTS & SERVICES Knights to the rescue on NOx emissions Lochinvar has added four models to its Knight range of water heaters so end users can meet emissions regulations. The latest phase of the Energy-related Products (ErP) Directive came into force in September 2018, introducing a maximum level of NOx emissions for water heaters. Lochinvars new Knight models produce between 22mg/kWh and 48mg/kWh comfortably inside the ErPs 56mg/kWh. They offer storage capacities of 108l to 358l, with recovery rates of 140 to 290 litres per hour based on a temperature rise of 50C.

The 6,846m2 building is located in a prominent corner position within the square and was fully refurbished with underfloor air conditioning. The building, described as a subtle blend of heritage features and contemporary finishes, now has services, including heating, ventilation and air conditioning, and has been transformed into modern offices. The system at 17 Devonshire Square is a CAM-V direct expansion system, using the plenum beneath the raised access floor as the supply air path with return, spent air received back at high level. Because there is no division in the floor plenum, adding and repositioning Fantiles is unrestricted, easily adapting to future change of use and making it ideal at Cat-B fit-out stage.

The range features 35kW and 54kW appliances, and the larger model can act as a high-efficiency alternative to gas-fired storage appliances. Lighter than glass-lined heaters, with a far greater life expectancy, the stainless steel cylinders also have extremely low heat loss figures as low as 1.41kW/h per day.

The Sound of Silence looks at common mistakes and discusses how to reduce noise and vibration to make internal drainage systems quieter. It also introduces Rehaus Raupiano Plus pipe, which has three layers to increase rigidity and enhance its sound-insulation properties. The Sound of Silence is the first free-to-download guide to be published under Rehaus Build Your Legacy campaign.

That was the message from Geze UKs national sales manager for window technology, Spencer Allen, during his talk at the Smart Building Show in London. Controlling a buildings heating, lighting, ventilation, air conditioning and other applications offers improved efficiency, reduction in energy consumption and extended product life-cycles, he said. The greatest return on investment, however, could be by creating better workplaces for the occupiers. According to Knoll Workplace Research, 90% of an organisations expenditure is on its people, with only 10% spent on operations and energy consumption. The need to look after our people is evident, said Allen, who suggested better ventilation could help with this. Natural ventilation will save a property between 10% and 30% in energy consumption, help remove air pollutants by as much as a third, and offer low-maintenance and easy-to-access operation of windows, helping staff feel in control and more satisfied in their working environments. Allen highlighted how technological advances have increased the opportunity for connectivity and how intelligent hubs, such as the Geze Cockpit, could integrate natural ventilation with the management of automatic doors, smoke and heat extraction, escape and rescue route management, and access control. But this requires designers to consider the proposed use of the building and to create a workplace that puts people at the heart of how it should operate, he added.
