Hot water made AquaEasy AquaEasy is an imaginative addition to the Alfa Laval range of domestic hot water systems designed for a control- lable, straightforward supply of hot water in apartment blocks, hotels, schools, sports centres etc. Compact, simple, yet effective AquaEasy provides up to 350kW of capacity within a slim, space-saving sil- houette, which allows it to be floor or wall-mounted or installed in a cupboard. AquaEasy can be connected to any heating source on the primary side, whether conventional gas boiler, district heating network or a renewable energy source such as solar panels or a heat


pump. A high efficiency CB60 copper-brazed heat exchanger transfers energy from the primary to the secondary side. A 2 or 3 port thermostatic valve combines with a rapid response thermostat to provide quick and precise regulation of the water temperature, while efficient insulation minimises heat loss.


Healthy buildings in a natural way The Healthy Building Concept®


of Renson®


aims at a healthy comfortable and energy effi- cient indoor climate in a natural way, combin- ing ventilation and sun protection. It offers a good air quality through natural ventilation as well as a pleasant temperature during summer through controlling solar gain by means of sustainable exterior solar shading and by applying intensive natural ventilation at night. Basic ventilation guarantees a perfect indoor air quality. In conformity with the stan- dards, a sufficient supply of fresh outside air used to force the contaminated inside air out of the building according to the principle of air supply, transit and extraction. This ventilation is permanently guaranteed through the supply of fresh air via window vents or acoustic ven-


tilators. Intensive night ventilation (Nightcooling) is the concept of natural airflow overnight to cool down a building and its air content.


Macbryde Homes use Automist from Plumis When Macbryde Homes embarked on designing a terrace of 2½ storey homes with open plan kitchen, dining and living room, they were faced with the problem of providing a cost effective and appropri- ate fire protection solution. For their open space design the Building Regulations demand that a protected enclosed stair- well is provided or they require the use of alternative compensatory measures such as sprinklers. The alternative was Automist


from Plumis, which uses a high pressure pump to generate a fine water suppres- sion mist from nozzles, which can be mounted under a standard monobloc mixing tap, on a work top, a wall, or on the side of the staircase with the pump assembly hidden under the staircase. The benefits include rapid and automatic fire suppres- sion and neat and economical installation.

Creating a quiet, sustainable internal environment


In any large, busy building, noise transfer from one area to another has always been a problem – but no more, with a revolutionary yet simple product by Passivent developed in association with Arup. WhispAir significantly reduces sound transmission from one area to another, whilst enabling low resistance airflow – essential in naturally ventilated buildings. This can help reduction in energy consumption as part of the continuing drive for zero carbon buildings, without compromising acoustic performance targets as described in British Standards and Building Bulletins. In a cross ventilation application, WhispAir is positioned at high level in the partition between two internal spaces, enabling air transfer with minimal pressure drop. The unique combination of design features, including a patented sound absorbing lining, is optimized to attenuate mid-fre- quency sound, typically the most problematic. Accredited laboratory testing has demonstrated that an acoustic performance of up to Dnew44 can be realised. WhispAir’s innovative design of an ABS sleeve with foam lining enables it to be flat-packed for easy transportation, with 16 product models available to suit most situations.

Gothic style Banwell castle gets fire protection Stunning 18th


century Banwell Castle in Somerset had suffered a fire in 1905 when


the fire brigade were battling away for a full two days. Owners, the Parsons family, embarked on a search in 2009 and selected the Detectomat SRC 3000. They then contacted Argos Fire Protection, who they knew worked with Detectomat. The Grade II* listed castle is now run as a bed and breakfast and is also open to the public as well as being a family home. The stone walls are so thick that there is no chance of a mobile phone signal and they knew that they had to be able to hear any alarm through the thick walls – the Detectomat alarm can be heard all over the building. Furthermore, they were determined to avoid unsightly wiring, which would mar the beautiful stone interiors. The Detectomat SRC 3000 wireless detect system includes optical smoke detectors with integral sounders, break-glass call points and heat detectors. Because installation is so fast, labour charges are kept to a minimum and there is very little disruption.
