Greg Penoyre and Sunand Prasad (recently elected President of the RIBA) have been in practice together for 18 years. In that time, they have garnered an eclectic portfolio of buildings that are both visually striking and practical, and for a variety of uses, including education, healthcare, housing and culture. "Transformations: The Architecture of Penoyre & Prasad" consists of eight essays written by Prasad: 'The Anchor of Function'; 'Architecture, Art and Culture'; 'Plan Section and Elevation'; 'Who Designs?'; 'From DIY to PFI'; 'Environments for Healing'; 'Environments for Learning'; and 'Working with Existing Buildings'. These texts discuss Penoyre and Prasad's engagement with their clients and examines its relationship to both architectural history and the contemporary situations and purposes for which the practice works. "Transformations" provides a unique and personal insight into Penoyre and Prasad's major projects, including Moorfields Eye Hospital, the Rich Mix Centre, Wolverhampton Civic Halls, Woodacre Farm Learning Difficulties Unit and the University of Portsmouth Frewen Library.

Retrofit for Purpose explores the art and science of bringing energy efficiency to existing buildings; one of the biggest challenges facing the industry today. The essays and case studies included here explore the main issues, offer practical solutions and provide a clarion-call to architects and clients for better, smarter retrofit. The eleven case studies focus as much on the transformation of usability and image as on the improvements in the energy and resource use of non-domestic buildings. The essay section puts these projects into a wider context, arguing that while there is much more to retrofit than energy efficiency, gathering, sharing and analysing reliable energy performance data are absolutely critical. The authors take a range of other retrofit variables; from client ambition to tenure, budget, use-type, age, context, fashion and fiscal arrangements and assess how retrofit can be made affordable, how it fits in with wider government policy and how performance can be measured. Lavishly illustrated, covering both theory and practice, and with essays from internationally recognised experts, alongside revealing best-practice case studies, Retrofit for Purpose will be of use to architects, developers, other construction professionals and clients alike.
