INTERNATIONAL PROJECT geometry was designed and manufactured using algorithm- aided parametric 3D design methods in order to achieve the required precision. The appearance of the façade will develop over the years towards a deeper, richer version of its initial hue. The design of the building envelope is intrinsic to the passive energy approach adopted by the project team. Detailed analysis of the façade performance has informed the environmental solutions and has allowed the team to minimise the requirement for mechanical environmental control systems, which facilitates the highly flexible architectural solution. The glass facades allow for large amounts of functional daylight in the public areas, reducing the use of artificial light and enhancing the quality of the interior spaces as a multifunctional citizen’s forum. The carefully planned placement and optimisation of building services has enabled the flexibility of the spatial arrangements. All public levels of the building are equipped with access floors to allow for changes in use during the estimated 150-year life span of the building. The library building will be extremely energy efficient. Its energy consumption level is that of a nearly Zero Energy Building (nZEB). This is mostly due to the efficiency of the building services. The material efficiency of the building has benefitted, among other things, from the use of wood in the exterior cladding. Building information modelling was used in both architectural and engineering design, as well as in checking the compatibility of the designs. Building information model will also be utilised for maintenance. The budget for the project was EUR98-mil and took just under three years to complete. The library is expected to attract 10 000 visitors per day and 2.5 million visitors per year. The library was crowned winners of the Helsinki library competition. The flooring of the library was made from timber. The library offers various services alongside an abundance of lounge spaces and auxiliary services within the building. www.timberiq.co.za // DECEMBER 2019 / JANUARY 2020 25
