The Livingstone Tower

The strength of the reinforced concrete structure is the main design feature which contributes to the durability of the Livingstone Tower. Some elements of the building envelope (windows) have already been replaced because of poor quality, and the rest of the building envelope is also due for replacement because of failures (muroglass panels) and inadequate U values (lack of thermal insulation). Some of the original interior finishes and fittings are due for replacement. The later adaptations and refurbishments have improved thhe appearance of many spaces. It is important that good quality finishes are used in future adaptations. The durability may be adversely affected by water penetration through the flat roof if this is not monitored.

The strong structure, large distance between the columns and large spans contribute to the adaptability of the building. This type of structure, combined with the deep plan and the position of windows, is suitable for uses which can be organized in medium size rooms or inn an open plan. The smaller rooms are too narrow because of the window spacing. The partitions with generous glazing towards the internal corridor are more suitable than full partitions, because of the need for natural light deep in the pl

lan. The generous floor-to-ceiling height allows for installation of suspended ceilings and raised floors, and thus for easier maintenance and alteration of services.

The energy conservation of the Livingstone Tower is adversely affected by the exposure to winds, unsatisfactory U values of the major parts of the building envelope and the inefficient heating system. The spaces in the centre of the deep plan need artificial lighting throughout the occupancy period. The glazed partitions between corridors and perimeter rooms would provide natural light in the corridors. This would also improve the appearance of the corridors. The planned conversion from electrical to gas powered wet heating system will significantly decrease the cost of energy consumption and the total energy consumption will be deecreased when the thermal insulation of the building envelope is improved.
