Modern Urban Landscapes is a significant contribution to the conversation on sustainable landscape design, providing energy efficient models and water saving landscape ideas. There are many factors that would help realise energy efficient landscapes, including (but not limited to) the use of energy saving lamps, such as LED; the integration and adoption of renewable energy, including solar-powered and wind-powered landscape lighting; energy-efficient landscape design, particularly through the correct placement and selection of shade trees, and the creation of wind breaks. This book shows techniques for creating landscapes that also save water, for example by choosing correct planting materials; reducing stormwater run-off through the use of bio-swales, rain gardens and green roofs and walls; reducing water usage in landscapes through best-practice water-wise garden techniques, including irrigation using gray water. Permeable paving materials can also help to reduce stormwater runoff and allow rainwater to infiltrate into the ground and replenish groundwater rather than run into surface water systems.

The Council on Tall Buildings and Urban Habitat's Outrigger Working Group has addressed the pressing need for design guidelines for outrigger systems with this guide, now in its second edition, providing a comprehensive overview of the use of outriggers in skyscrapers. This guide offers detailed recommendations for analysis of outriggers within the lateral load resisting systems of tall buildings, for recognising and addressing effects on building behaviour and for practical design solutions. It also highlights concerns specific to the outrigger structural system, such as differential column shortening and construction sequence impacts. In this edition, a new chapter explores the use of 'hybrid' outrigger systems that can 'tune' the stiffness of outrigger trusses, use leverage of the outrigger arms to drive non-linear damping devices, and use yielding materials that absorb seismic energy. Several project examples are explored in depth, illustrating the role of outrigger systems in tall building designs and providing ideas for future projects. The guide details the impact of outrigger systems on tall building designs, and demonstrates ways in which the technology is continuously advancing to improve the efficiency and stability of tall buildings around the world. The new second edition features updated design considerations to reflect current practices, expanded systems organisation and examples, and updated recommendations and suggestions for future research.
