CONTRACTS AND PROJECTS Borehamwood development


The Schöck Isokorb thermal break module type KS, for concrete-to- steel connectivity, has been combined to good effect with Holorib decking for the balcony construction of an extensive new residential development at Borehamwood in Hertfordshire. This is the first project in the country where the Isokorb has been used in conjunction with Holorib, which provides permanent shuttering and is an extremely strong profile allowing the design of a thinner slab. Foster House, inMaxwell Road, provides 114 one and two-bedroom flats, all of which meet with level three of the Government’s Code for Sustainable homes. The Code measures the sustainability of a new home against nine categories of sustainable design, rating the whole home as a complete package. The type KS Isokorb from Schöck provides a structural, thermally efficient connection for the steel balcony to the composite slab. The product is simply positioned within the Holorib decking and tied to the slab reinforcement. The design and detailing of this connection is carried out, in conjunction with the project engineer, by the Schöck team of structural engineers at the design office in Kidlington. The KS is fully BBA certified and LABC registered, maintenance free, and once installed can be fine tuned and adjusted to optimise fitting tolerance. Isokorb modules meet full compliance with the relevant UK building regulations. These require that the temperature factor used to indicate condensation risk (fRSI), as described in BRE IP1/06 – a document cited in Building Regulations Approved Documents Part L1 and L2 and Section 6 in Scotland – must be greater than, or equal, to 0.75 for residential buildings.With the type KS Isokorb the temperature factor (fRSI) is in excess of 0.91 and furthermore enables optimum compliance with the Building Regulations Approved Documents by using numerical modelling to calculate the building’s energy performance.

Turning daylight into electricity


Acurtainwall engineering business in Chessington claims to be one of the first commercial firms in the Royal Borough of Kingston upon Thames to install a photovoltaic systemto reduce its carbon emissions.As part of its commitment to protecting the environment, StructuraUKLtd sought professional advice about cutting its electricity consumption. Installing solar PVpanels in a portrait configuration on the south-facing roof of the company’s office and factory premises provided the answer - turning daylight into electricity. The system, designed and installed by Red Solar Ltd, consists of 165 SchücoMPE Series 05, 215Wp polycrystalline solarmodules or cellswith an output peak of 34.475 kWp which is expected to generate in the region of 29,750 kWh per annum. Thiswill considerably reduce StructuraUK’s electrical costs and avoid approximately 17 tonnes of harmful CO2 emissions per annum. Themodules fully complywith stringent ISO9001 and ISO14001 quality and environmental standards.An inverter converts the direct current produced by the solar PVpanels into the alternating current required. In order tomonitor howmuch electricity StructuraUKis generating, the company has fitted a real time display unit (RTD) in its reception area. By generating its own electricity fromsolar PVpanels, Structura UKwill receive payments for everyKilowatt produced for a period of 25 years after installation under the government’s Clean Energy Cash Back scheme. In addition, StructuraUKwill be paid by its electricity company for the surplus energy it feeds back into the national grid through a Feed-in Tariff, a government initiative to encourage businesses to use renewable energy systems, thus reducing carbon emissions, by offering tax-free income and lower electricity bills. The PVpanels are fixed to a discrete aluminiumalloy framing systemandmeasure 1498mmlong x 1001mmwide x 46mmdeep. They offer a 25-year, 80 per cent power output warranty period, and a five-year product guarantee.
