Challenges: Tall Buildings & Sustainability – the Case ‘Against’
“The age of skyscrapers is at an end. It must now be considered an experimental building typology that has failed”
Kunstler & Salingaros, in Roaf et al (2005)
Factors:
• Construction & Operation
• Internal Environment / People
• Urban
Challenges: Tall Buildings & Sustainability – the Case ‘Against’
Construction & Operation
Higher embodied energy in constructing at height – structure, materials etc.Greater wind loading at height (impact on size of primary structure, façade design
etc).High energy consumption in operation – elevators (up to 15% of bldg energy
use), services etc.
Higher energy consumption for cleaning and maintenance (e.g. replacement of façade silicon joints).
Energy consumption is a small percentage of total costs (salaries etc) – little incentive for owners / operators / developers.
Implications of Power failure (impact on vertical circulation, safety etc).Recycling potential / urban impact of demolition / disposal of materials after
demolition.
Challenges: Tall Buildings & Sustainability – the Case ‘Against’
Internal Environment / People
Less net usable area to gross area and restrictions on internal planning; vertical circulation core etc.
Anti-social internal environment – lack of open, recreational, communal space (esp. in residential).
‘Sealed’ environments at height – thus requirement for air conditioning, artificial lighting etc.
Safety and Security fears (especially post 9/11) – including safety during construction.
Increased travel time (wasted time?).People suffering from vertigo – building occupation / human rights legislation?
Challenges: Tall Buildings & Sustainability – the Case ‘Against’
Urban Factors
Impact on urban scale; cities that ‘don’t want’ to be tall?The poor ground floor interfaceWind downdraftsOvershadowing (solar rights / right to light)Wind rights (ventilation?)Overpopulation in certain localities / greater demand on existing urban services
and infrastructure.
Climate Change will increase all these pressures on high rise – wind, storm, solar, power failure etc …….
Challenges: Tall Buildings & Sustainability – the Case ‘For’
Efficient land use in population concentration – reduced suburban spread / loss of countryside.
Denser cities = reduced transportation (and consequential impact on environment). Reduced size of infrastructure networks (urban / suburban, power, services, waste
disposal etc).Proximity of residence and workplace; therefore less travel time (less wasted time?).More of the ground floor / urban level can be dedicated to ‘public’ use e.g. retail.Standardisation of floor plates and use of materials – prefabrication efficiencies? Higher wind velocities at height = greater potential for harnessing wind energy.Potential for natural ventilation through increased ‘stack effect’ etc.High ‘thermal mass’ potential for use in natural ventilation / heating / cooling strategies.Potential for good internal daylighting (and thus reduced energy).Increased quality of life at height – view etc?The potential for ‘secure’ communal / recreational spaces at height, away from traffic,
pollution etc.Increased ‘legibility’ of the city – urban signposting etc.Life-cycle costing; re-use of building structure, services etc in refurbishments.
The U.K.
Factors:
- longer life expectancy- smaller household size(single person households, divorce rate, children outside marriage, etc)
Results:- a government demand of
2.6million new homes by 2020
- An annual requirement of 189,000 new homes
“the high energy, gas-guzzling fully glazed office block is … at the end of an era … façade design is on the frontline of a change”

A new Vernacular for the Skyscraper?
Seven Design Principles for future Tall Buildings ……….
1. Should vary with height – not be just vertical extrusions of an efficient floor plan.
2. Varying Texture and Scale essential – should be designed as many small buildings harmoniously together, rather than one piece of iconic sculpture to be viewed from afar?
3. New functions to be introduced4. Communal, open, recreation space vital5. More facade opacity (and variation / texture) in skin / cladding6. Organic matter (vegetation) to become an essential part of the
material palette.7. More physical, circulatory, social and programmatic
connections (skybridges!).
Tall Buildings have an opportunity to lead the way for the benefit of the entire construction industry, due to the financial and professional expenditure involved and thus the opportunity for incorporation of experimental technologies etc......
