Just how smart are intelligent buildings?
Linda Forbes Unit A3
An intelligent building • should be productive, safe, healthy, thermally, aurally and visually comfortable; • has the potential to serve future generations: sustainability or adaptability over its life cycle, while safeguarding environmental resources; • can be built within some cost constraints whilst retaining market value.

Benefits of intelligent buildings Lighting
More natural daylight Lower energy requirement
Ventilation
Stack effect; night cooling; mixed mode Lower energy requirement
Heating
Solar gain used to pre-warm incoming air Lower energy requirement
Environment
Lower energy requirements Renewable energy (Merton Rule)

Issues to consider Proximity of other buildings
Less solar gain; less daylighting Air turbulence; wind speeds and direction
Urban Heat Island (UHI) effect
Higher temperatures at night Diurnal range reduced; less night cooling
Pollution from vehicles and industry
Noise and smell Photochemical smogs
Double Ventilated Facades

Regional Government
Regional Spatial Strategy (Regional Planning Bodies RPBs and elected Regional Assemblies inc London)
Development strategy covering 15-to-20 year period Contributes to achievement of sustainable development Incorporates Regional Transport Strategy
Local Government
Local Development Framework (District Councils, Unitary Authorities, National Parks)
Development plan documents Local development scheme Statement of community interest Annual monitoring report Supplementary planning documents Local development orders and simplified planning zones

Ancient Rights in UK
Right of light, once right acquired Freedom from noise or smell No right to wind
Potential outcomes of increased building density Increased energy demand Higher running costs Who is liable?
Renewable energy supply
Failure to meet renewable obligation (10% or more)
Local authority for granting permission?
In breach of planning regulations?
Owner of buildings in proximity?
Require building more capacity off-site to meet requirements?
Conclusions • Intelligent buildings can deliver energy savings • Highly technical, with high embodied energy • Planning systems may defeat objectives • What future in a hotter, more humid and crowded world?
