GROUND FLOOR PLAN will be carried out in accordance with Chartered Institution of Building Services Engineer standards – a key component of an energy-efficient building, while power factor correction – to optimise the balancing of the electrical system for increased energy efficiency, is included in the design. SOLAR ENERGY SOLUTIONS COMMENT The solar installation at Pam Golding on Main is a 36 kWp system. The system comprises one hundred and twenty 300 Watt polycrystalline solar photovoltaic modules, optimally inclined at ±15 degrees to produce 59,885.14 kWh energy per year. This is equivalent to a reduction of 53 tons of CO2 per year, which is the equivalent of taking more than 80 cars off the road. The installation covers an area of 225m2, and is able to produce up to 25% of the total power requirements of the building when operating at capacity. The PV system achieves financial savings for the new building by reducing the amount of energy as well as the maximum demand utilised from the utility. Pam Golding TYPICAL FLOOR PLAN CONSULTING CIVIL & STRUCTURAL ENGINEERS REPORT De Villiers Sheard were originally appointed as consulting Engineers for am Golding on Main in 2001. The project parameters, and architectural characteristics, changed several times over the period between 2001 and the completion in 2015. The most significant structural implication of the various interactions of the design related to the depth of basement and the requirements for lateral support to retain surrounding buildings and roads. The eventual basement provided for 3 levels of underground parking. The lateral support was installed by Franki and comprised concrete gunite arches between ‘CFA’ piles. These were temporarily tied back by prestressed archors. These were destressed and rendered inert once the concrete structure was built. The building is founded on ‘CFA’ piles which were installed from the base of the excavation. Suspended slabs comprised both conventionally reinforced concrete (parking and ground floor) and post-tensioned (1st to roof). 45
