- Your Building Can Save the Planet
- Resource Positive Architecture
- The heating and cooling of buildings emits at least 30% of the world's greenhouse gases.
- If you add in the manufacture and transportation of construction materials buildings account for 48% of the world's greenhouse gases.
- Our cities and communities consume 75% of the world's energy and generate 80% of its greenhouse gases.
- Every year in North America, buildings release some 2200 megatons of carbon dioxide into the atmosphere.
- In Canada buildings account for: · 50% of the natural resources used in a year
- In Canada buildings account for: · 50% of the natural resources used in a year · 25% of the materials in landfills
- In Canada buildings account for: · 50% of the natural resources used in a year · 25% of the materials in landfills · 12% of the non-industrial water usage.
- In the United States , the annual cost of building-related sickness is estimated to be at $58 billion.
- Green buildings could generate an additional $200 billion a year in the United States in worker performance by creating healthy workplaces.
- More than half of the world's new construction is taking place in China and India alone.
- China and India could cut current building energy consumption by 25 percent simply by using energy more efficiently.
- In China a dollar spent on green buildings has a 4 times greater impact than a dollar spent on energy generation .
- Green and Healthy Buildings have many benefits .
- Green and Healthy Buildings can decrease: · Absenteeism by 15%
- Green and Healthy Buildings can decrease: · Absenteeism by 15% · Carbon Emissions by 35%
- Green and Healthy Buildings can decrease: · Absenteeism by 15% · Carbon Emissions by 35% · Energy Costs by 30%
- Green and Healthy Buildings can decrease: · Absenteeism by 15% · Carbon Emissions by 35% · Energy Costs by 30% · Hospital Stays by 2.5 days
- Green and Healthy Buildings can decrease: · Absenteeism by 15% · Carbon Emissions by 35% · Energy Costs by 30% · Hospital Stays by 2.5 days · Waste Management Costs by 50-90%
- Green and Healthy Buildings can decrease: · Absenteeism by 15% · Carbon Emissions by 35% · Energy Costs by 30% · Hospital Stays by 2.5 days · Waste Management Costs by 50-90% · Water Usage by 30-50%
- Green and Healthy Buildings can increase: · Factory Production
- Green and Healthy Buildings can increase: · Factory Production · Retail Sales per Square Foot
- Green and Healthy Buildings can increase: · Factory Production · Retail Sales per Square Foot · Office Productivity by 2-20%
- Retrofitting existing buildings with current, cost-effective technology, would reduce our climate change impact by 40%.
- Using new technology would reduce our climate change impact by 60%.
- Using existing technology we can now construct Net Zero Buildings which consume as much energy as they use and have a neutral effect on the environment.
- But we could do more.
- Resource Positive Architecture is about buildings and communities that have a regenerative or positive effect on the environment.
- Resource Positive Buildings generate more energy than they consume.
- Resource Positive Buildings purify more water than they use.
- Resource Positive Buildings sequester more carbon than they emit.
- Resource Positive Buildings also have the potential to generate revenue for their inhabitants.
- The performance of a building is determined: · 25% by its architecture · 50% by its systems · 25% by the behaviour of its occupants.
- We can use all three to create Resource Positive Buildings.
- Here's how we do it: 105% Total 20% Alternative Energy Systems 15% Better Insulation and Materials 20% Energy Smart Appliances 10% Energy Efficient Lighting 15% Change our Behaviours 15% Passive Solar Design 10% Metering & Monitoring
- Metering and Monitoring: People will use 12% less energy if they have legible meters that tell them how much they are using.
- Passive Solar Design involves no advanced technologies but can generate huge savings.
- Passive Solar Design includes: · Orientation of the building to maximize daylight · Natural Ventilation · Shading Devices · Passive Heating with Thermal Mass · Efficient Envelopes.
- Passive Solar Design: New technologies can capture and concentrate natural light and deliver it 100 feet inside a building - with a 25% saving in lighting power bills.
- Change our Behaviours: · Turn down the thermostat · Turn off the lights · Power off the computer.
- Energy Efficient Lighting: Compact Fluorescent Bulbs use 75% less energy than incandescent bulbs and deliver the same amount of light.
- LED (Light Emitting Diode) bulbs now under development will offer even more energy savings, last longer and be better for the environment.
- Energy Smart Appliances: Our electronic devices are energy hogs and they're getting worse.
- Energy Smart Appliances have the following energy savings over conventional models: · Refrigerators 15% · Clothes Washers 50% · Dishwashers 25% · Air Conditioning Systems 20%.
- Better Insulation and Materials: The Passive House uses superinsulation and other methods to avoid the need for a furnace or air conditioning system.
- Better Insulation and Materials: · Build out of Wood
- Better Insulation and Materials: · The manufacture of most building materials generates greenhouse gases. · Wood soaks up and stores greenhouse gases as it grows.
- Alternative Energy Systems: · Solar Thermal · Solar Photovoltaic · Wind · Geothermal.
- Alternative Energy Systems: · Solar Thermal Collectors can reduce water-heating costs by 70%.
- Resource Positive Architecture is the best means of reducing global warming.
- Collaborative research is the best means of making resource positive buildings.
- The problem is: Levels of building research pale in comparison to amounts being invested in other sectors .
- In the United States research on green buildings was only about 0.2% - two-tenths of one percent - of all federally-funded research from 2002 to 2004.
- We need an international program of research, development and commercialization.
- Schools of architecture and engineering working with practitioners could move us quickly towards resource positive architecture.
- Great progress could be made simply by connecting together existing initiatives and sharing best practices.
- A comprehensive approach provides a competitive advantage.
