Smart Buildings
- 1. SMART BUILDINGS By- MOHIT Kumar 13CE01006 IIT Bhubaneswar
- 2. CONTENTS • What are smart building ? • Smart windows • Smart shade • Smart concrete • Smart wall • Smart brick • conclusion
- 3. What are Smart buildings?? • Deliver useful building services that make occupants productive at lowest cost and environmental impact on building lifecycle. • Smart building is Integrated Intelligent Automated High performance Designed for longevity
- 4. SMART WINDOWS • glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. Generally, the glass changes from translucent to transparent changing from blocking some (or all) wavelengths of light to letting light pass through.
- 5. SMART SHADE 1. controls the amount of sunlight passing into a building's interior a. With the help of sensors
- 6. SMART SHADE b. With the help of complex alloys 2.controls the level of carbon dioxide in a room
- 7. SMART CONCRETE Can sense the stress and strain applied on it. Made as a sensor by the addition of carbon fibres or carbon nano tubes.
- 8. CEILINGS • Anti microbial ceilings • Destabilise the cell membrane • Inhibit critical enzymes • DNA interruption ROOFING •Building-integrated Photo Voltaic (BIPV) •Mono crystalline silicon, polycrystalline silicon and thin film silicon (using amorphous silicon)
- 9. 1.Trombe wall 3.Micro encapsulated PCM 2.PCM SMART WALLS
- 10. • Monthly expenses comes around $1600 • Reduction by 40-50% • Hospital infections are adding $5 billion every year to US national healthcare costs • The study showed a 95.8 % reduction in microbial growth
- 11. SMART BRICKS SMART AIR BRICKS Smart brick for controlling lego-vehicle Bricks stuffed with sensors, signal processors and wireless communication links warning about hidden stresses, or damage in the aftermath of natural calamities like earthquakes, storms or hurricanes. A "smart brick" that could monitor building's health and save lives. A sample of smart concrete using electrical properties as an ideal sensor of stress, weight and vibration. Deborah Chung Chang Liu
- 12. ENERGY EFFICIENCY OF BUILDINGS New insulation materials: thinner and able to store energy • nano porous silica • phase change materialswall coating support balls of paraffin Lighting efficiency with LEDs : from 20 toward 150 lumen / W
- 13. Self-powered buildings Dynamic Tower Dubai Self rotating tower WALGREENS: The first net-zero store, in Evanston • More than 800 solar panels on the roof. • Two vertical wind turbines. • Geothermal cooling and heating. • LED lighting and daylighting. • Carbon dioxide refrigerant for heating, cooling and refrigeration equipment. • Energy-efficient building materials
- 14. REAL WORLD EXAMPLES FOR ENERGY EFFICIENT BUILDINGS • Stop and Shop, Royal Ahold (Massachusetts - USA) • High energy efficiency lights with automated lighting control • Use of natural light (50 roof glass panels), • Results : • Annual energy savings : 25%, • 50% less energy for lighting • Increase of average customer purchase versus other stores, • Blanquefort College (Aquitaine - France) • Use of solar energy : 120 m2 of solar collectors and 140 m2 of solar panels, • On-line monitoring of energy consumptions and air quality, • Results : • Coverage of energy needs by renewable energy : 42% • Annual energy consumption : 72 kWh/m2 • Annual CO2 emission : 8 kg/m2 • 8 Brindabella Circuit, Canberra (Australia) • Full control of HVAC, lighting, … per office zone with activity sensors • Use of eco efficient lights and photovoltaic panels for hot water production • Results : • Energy savings : 45% • 45% less CO2 emissions • Hot water energy needs 100% covered by on site solar energy 2001 2005 2006
- 15. CONCLUSION • Longevity • Energy efficiency • Comfort and satisfaction • Utilize new technology • Reducing man power • Advanced control systems
- 16. TAKE HOME POINTS • Smart buildings are automated. • Senses indoor and outdoor activities and react in most efficient way. • 45% energy efficient. • Reduction in pollution 30%. • Reduction of waste.

Editor's Notes
- In age of technology, believing in every out of box imagination is valid because technical wonders can make that thing really happen’
- It Hosey's Smart Shade employs the thermodynamics of zinc and steel to control the amount of sunlight passing into a building's interior. Yang and Benjamin's Living Glass uses elastic shape memory alloy (SMA) wires to control the level of carbon dioxide in a room. The blind consists of a composite layer of zinc and steel, two metals with different thermal tendencies. Expansion and contraction of these sandwiched materials in response to temperature cause the blinds to curl up in winter (allowing more sunlight in) and curve down in summer (allowing less).

- 1.Smart bricks allows air to pass through but not water 2. Built into a wall, the brick could monitor a building’s temperature, vibration and movement. Such information could be vital to firefighters battling a blazing skyscraper, or to rescue workers ascertaining the soundness of an earthquake-damaged structure

- 1.In its first experiment in net-zero stores, Walgreen is combining several clean energy technologies, which it plans to extend to many of its 8,000 stores. The first net-zero store, in Evanston, Ill., will get renewable energy from solar, wind and geothermal, along with extremely efficient refrigerators, LED lights and green building materials. 2.Solar panels, wind energy
