Sustainability Defined Life Cycle Design Operations Renewable Resources Reflection Conclusion Questions
Sustainability Defined
Sustainability – “The ability to provide for the needs of the world's current population without damaging the ability of future generations to provide for themselves. When a process is sustainable, it can be carried out over and over without negative environmental effects or impossibly high costs to anyone involved.”www.sustainabletable.org/intro/dictionary/
Sustainable Design – “Sustainable design or building “green” is an opportunity to use our resources efficiently while creating healthier buildings. It provides cost savings to all through improved human health and productivity, lower cost building operations, and resource efficiency—and it moves us closer to a sustainable future.” - http://www.ciwmb.ca.gov/greenbuilding/
Sustainable Building – “A sustainable building, also known as a green building, is a structure that is designed, built, renovated, operated, or reused in an ecological and resource-efficient manner. Green buildings are designed to meet certain objectives such as protecting occupant health; improving employee productivity; using energy, water, and other resources more efficiently; and reducing the overall impact to the environment.” - http://www.ciwmb.ca.gov/greenbuilding/Basics.htm
Life Cycle
Steps toward a sustainable building are made in each phase of a building’s life cycle
Design* Construction Operation* Renovation Etc.
Design
The design process is crucial in the creation of a sustainable building
The building must be designed with the ability to help further the goal of self-sustainability
Design Considerations
A designer must consider: Window size, placement, and type Floor to ceiling heights Aesthetics; efficiency can be
beautiful
Design Alternatives
A designers view on conservation: Ideas of using the “rubble” from a
destroyed building to give it new life Utilizing materials found on site Lebbeus Woods
Operations
Statistics – Current Buildings Root of 30% of all green house
emissions Produce 136 million tons of waste
annually Consume 36% of total energy produced
in U.S. Consume 65% of total amount of
electricity produced
Operations
Actions New ways to use current energy –
through new innovations of current technology
Development of new energy sources (i.e. hydrogen, biomass)
Use of renewable energy sources (i.e. solar, hydro, wind, geothermal)
Hydrogen
Most plentiful element on Earth When isolated, can produce clean
burning fuel Can be used for both electricity and
transportation Viewed by many experts, on a large
scale, to be the only true replacement to fossil fuels
Bioenergy
Derived from stored biomasses animal waste, plant matter, agricultural residue, landfill methane, and much more
Very versatile Can be used in the energy forms of
steam, heat, or electricity, but also can be converted to a fuel for direct combustion, and co-firing.
Solar
Derived from the sun to produce clean burning fuel through utilization of photovoltaics
Constantly replenished Two forms
Passive – windows, skylights Active – devices such as boilers and
furnaces being ran off of electricity produced by solar cells
Hydro
Derived from natural movement of water which is then converted into electricity
Accounts for 10% of United States’ total energy production
Increase in utilization is unlikely due to dwindling numbers of new available sites and strong opposition from environmentalists.
Wind
Fastest growing renewable resource Just until recently have wind turbines
and other energy producing wind devices been implemented into the actual building design
Dependant on climate and weather conditions
Intrusive to environment
Geothermal
Originates from heat within the Earth Obtained through thermal conduction Energy can be harnessed in the form
of hot water or steam Two uses
Direct – heating of building or drying food Indirect - production of electricity
through a generator to distribute power.
Reflection
Wise energy choices are just the beginning. A building must be:
Aware of itself Aware of its environment Aware of its own effects on the
environment
Aware of itself
Awareness of energy its energy needs
Awareness of system capabilities Such awareness can be achieved
through the use of technology Sensors Databases Robotics
Aware of its environment
Understand external conditions in order to make efficient system adjustments
Decrease the need to design all systems for extreme conditions
Aware of how much energy is available to it at any given time
Awareness achieved through technology including innovative software and sensor networks
Aware of effects of environment
Take steps toward reducing impact Note when more emissions are made Note what positive impact it can have
on its neighboring community or society at large
Can it produce extra energy and put it to a humanitarian use?
Conclusion What is an intelligent building?
An intelligent building is a self sustaining structure independent of all outside variables in which appeases all stakeholders’ needs in the most efficient manner possible through out its entirety.
An intelligent building is one which utilizes various methods (including technology) in order to improve comfort, increase efficiency, reduce impact, and improve the building process in order to effectively serve its purpose as a structure.
Is a sustainable building an intelligent building? YES! A sustainable building, through adaptive computer
technology, would produce all required necessities throughout its entire life cycle while efficiently utilizing resources and having a minimal impact on its surroundings; thus achieving “Intelligence”!
