- 5. BUILDING AN ENVIRONMENTAL ETHIC: architecture – fitting in the environment
- 7. WHAT IS ENVIRONMENTAL DESIGN? “The modern architect has produced the most flagrantly uneconomic and uncomfortable buildings, which can be inhabited only with the aid of the most expensive devices of heating and refrigeration. The irrationality of this system of construction is visible today in every city: glass-sheathed buildings without any contact with fresh air, sunlight, or view.” Lewis Mumford (1895-1990), American architectural critic and scientist
- 8. ENVIRONMENTALLY SENSITIVE DESIGN In harmony with, and in response to the climate. Use natural solar and ventilation Minimize dependency of non-renewable energy sources Attempt that there will be quality and resources remaining for following generations.
- 9. SUSTAINABLE BUILDING - THE SUSTAINABLE ETHIC Not a new building style A new way to think about how we – design –construct - operate buildings Primary goal Lessen the harm of poorly designed buildings, by using the best of ancient building approaches, in logical combination with the best of new technological advances. Ultimate goal To make buildings to net producers of energy, food, clean water, air, beauty, and healthy human and biological communities Trying to take less from the earth and give more to people.
- 10. SUSTAINABLE DESIGN - DEFINITIONS Sustainable development is seeking to meet the needs of the present without compromising those of future generations. (Kyoto Protocol) Sustainability envisions the enduring prosperity of all living things – seeking to create communities, buildings, and products that contribute to this vision. (American Institute of Architects) “Sustainable design is the careful meshing of human purposes with the larger patterns and flows of the natural world.” (David Orr, educator and author) “Sustainable design is a process that supports and improves the health of the systems that sustain life.” (Bill Reed, architect)

- 15. RADICAL PHILOSOPHY/CONCEPT WASTE = FOOD (the HUMAN RACE is the only species to DESIGN things with the INTENTION that they become GARBAGE!) MIMIC NATURAL CYCLES Design for a closed loop where WASTE becomes FOOD and FEEDS back into a healthy cycle… Cont.’ In architectural terms: changing the current “cradle to grave” method of building into a “cradle to cradle” methodology – designing reusable building products
- 16. Cont.’
- 17. Cont.’ INCONVENIENT TRUTH buildings are responsible for between 40% to 70% of world carbon emissions THEREFORE: the way we design buildings MUST change that we don’t use up our natural resources, in terms of building Materials the way how buildings use energy MUST change

- 20. Cont.’ RADICAL is PASSIVE PASSIVE DESIGN The use of SUN–WIND-NATURAL LIGHT To heat, cool, and light architecturally- responding effectively to local climate
- 21. Cont.’ SUSTAINABLE CHECKLIST Ideally a sustainable building should: make appropriate use of land use water, energy, timber, and other resources efficiently enhance human health strengthen local economies and communities conserve plants, animals, endangered species, and natural habitats protect agricultural, cultural, and archaeological resources be economical to build and operate be nice to live in “Treat the Earth well. It was not given to you by your parents. It was loaned to you by your children." Kenyan Proverb

- 23. Cont.’ THE PROBLEM - THE CHALLENGE We are not ready for it!!! Not enough fuel to heat and cool the present buildings Increasing heating and cooling needs for additional buildings we might add between now and then…. Supposedly there is enough coal to be mined to maintain energy consumption for hundreds of years Coal produces more GHG than burning oil and gas § if we run out of oil - we will just burn coal…??? Architects need to figure out, how to solve this problem - designing buildings more sustainably. We need to figure out, how to use less fossil fuel
- 24. Cont.’ THE SOLUTION Environmental/Sustainable Architecture!!! The Design and Construction Industry the potential single largest contributor to solutions in compliance with the Kyoto Protocol and for creating long term ecological sustainability. Environmental Design - a way towards sustainability. Architectural Profession -Great potential for ‘Environmental Leadership’ -No one else in the building industry is so educated to be able to incorporate all aspects of technology, environment, culture and design into our built environments.
- 25. FIVE PRINCIPLES of ENVIRONMENTAL ARCHITECTURE (Thomas A. Fisher, Educator USA, 1992) Healthful Interior Environment Energy Efficiency Ecologically Materials Environmental Form Good Design
- 26. FIVE PRINCIPLES of ENVIRONMENTAL ARCHITECTURE (Thomas A. Fisher, Educator USA, 1992) 1. Healthful Interior Environment materials and building systems shall not emit toxic substances and gasses into the interior - air can be revitalized with plantings. 2. Energy Efficiency Cooling, heating, and lighting shall conserve or eliminate the energy use - the building’s energy use should be minimal. 3. Ecologically Materials products that minimize the destruction of the global environment 4. Environmental Form The design must be related to the site, the region, and the climate, the ecology of the site is to be conserved. 5. Good Design provides efficient, long-lasting, and well-designed used areas, circulation, building form, mechanical systems, and construction technology. Finished buildings shall be well-built, easy to use and beautiful.
