Cost model: 21st-century university building | Features

Design issues for specialist space
Libraries and learning resource centres
Design drivers	Solutions
Continuing expansion of library collections	Greater use of electronic journals, provision of flexible internal accommodation to allow for growth of hard and soft copy collections
Increasing requirements for group-based working	Provide separate spaces for quiet and group working and special consideration of acoustic management in open-plan areas
Greater use of IT	Provide central IT resource areas to reduce network costs and to control noise. Increase space allowances to permit screen and desk working. Provide quiet work space for book-based study
Environmental control	Maximise natural ventilation and daylight where possible. Restrict use of cooling to archive and IT areas only where conditions require it
Research facilities	听
Need to attract research scientists and external funding	High-quality architecture, high standards of internal and external environment and up-to-date equipment
Facilitation of creative multidisciplinary working	Provision of hierarchy of workplaces to enable group and solo working and range of spaces to encourage interaction
Flexibility to accommodate change	Flexible fit-out and servicing solutions that facilitate replanning and restacking
Separation of undergraduate teaching and graduate research activities	Clear separation of activities either through the development of stand-alone buildings or the internal planning of larger schemes
Laboratories	听
Close environmental control	Extensive, high-capacity building services, large ceiling voids, solid floor slabs to control vibration and avoid infestation in floor voids
Quality of working environment	Quality of write-up areas, flexibility of lab space and quality of natural light and air-conditioning systems
Flexibility	Modular laboratory design and services distribution, easily accessible services installations, independent structure and services
Security to protect research projects and equipment	Physical and electronic security measures, balanced against requirements to promote interaction between researchers. Specialist security for animal houses and other high-risk areas
Teaching spaces	听
Flexible floorplates	Column-free space, lightweight partitions, regular planning grid, small power and IT distribution equivalent to commercial office standards to provide flexibility for replanning
High-quality space	Shallow floor plates of 12-15 m for daylight and natural ventilation, clear orientation, use of atriums to provide circulation and social space, use of good-quality, robust materials
Low operational costs	Natural ventilation, limited cooling and ventilation for peak lopping only, and use of cost-effective sustainability features
