part 1: Examining Sustainability and Ourselves
concept of sustainabiltiy
_sustainability is more than maintaining a stasis
_we cannot live as we are now
_humans are a part of nature and must recognize this to see integrated solutions
_live within and inspired by nature
_look to a re-conceptualization of values, ideals and methods to provide a sustainable path
what does sustainability need?
_we must change perceptions and practices
_high quality of life with minimal impact
_reduce and eventually eliminate consumerist and disposable society mindset
_reduce, reuse, recycle
_interdisciplinary cooperation to derive solutions
_systems theory approach to modelling and feedbacks
applicability of sustainability
_sustainability must be applied unilaterally to work
_costs must be subsidised to provide incentives to make it attractive to everyone
_governments need to apply legislation to push for sustainable actions and practices
problems and barriers tosustainabiltiy
_sustainability is hampered by attitudes and ingrained societal values
_sustainability is good, but making money and having ‘stuff’ is better
_North American sense of entitlement and concept of the ‘American Dream’spreading globally
_rampant consumerism
_long term ROI a hard sell
_do we lose or gain humanity through sustainability?
_will place survive?
approaches to sustainability
_status quo
_minimal impact _small steps _change values as long as they are profitable
_medium impact _conservation and reduction _efficiency and environment more important
_extreme _legislation _paradigm shift _net zero _live completely in balance with nature
sustainability and architecture
_more efficient and ecologically friendly design
_lower impact development
_viable for multiple generations
_building performance programs _LEED _builtgreen _R-2000
our approach to sustainability
_awareness is key
_informed decision making
_lower impact
_as efficient as possible
_limit use of new raw materials
_use only what we need
_responsible development
_design with sustainability in mind
_look at the past as we design the future
examples of sustainability
_solar initiatives _ABENGOA Solar _SOLUCAR project _powers small town _eventually will power Seville
_masdar city _zero waste, net zero city in persian gulf _automobile free
examples of sustainability
_electric transportation
_tesla motors _all electric vehicles _proven viability
_daimler _electric smart car _commuter vehicle
_guided light rail _translohr GLR _electric mass transit _lower impact than traditional light rail
examples of sustainability
_CMHC Equilibrium _net zero demonstration homes _EcoTerra _Eastman, Quebec _modular factory construction _solar energy and heat _80% more efficient than standard home
examples of sustainability
_solar decathlon _international showcase of net-zero and zero waste technologies
_team alberta _2009 entry _aims to be self sufficient
part 2: EEEL Building Examination
Insert info here
building emphasis
_pedestrian access
_learning by visualization
_flexible design layout
_day lighting
_innovative design: mechanical system
pedestrian access
_encourage use of stairs
_learn from landscape
_interdisciplinary interactions encouraged
_visual connection from the promenade to the labs
flexible design
_easily adapted to accommodate growth and future changes.
_to limit the amount of ‘down’ time required to reconfigure
_reusing existing resources
daylighting
_reduce energy costs
_increased productivity
_increased learning ability
_for most spaces that are frequently occupied
material selection
_glass curtain wall system
_rundle stone
_douglas fir
_glass storefront walls are easily relocated
_complex analysis for selecting materials
mechanical system
_earth tubes
_heats or cools the outdoor air to +4 degrees Celsius
_heat or cool the air to the appropriate temperature via mechanical system
_pump to rest of building
_saves the energy required to heat (-30 air) or cool (+30 air)
LEED
_NC New Construction and Major Renovations
_CI Corporate Interiors
_EB Existing Buildings
_CSCore and Shell
_H Homes
_ND Neighbourhood Development
LEED
26 – 32 points = Certified
33 to 38 points = Silver
39 – 51 points = Gold
52 + = Platinum.
sustainable sites
_limit pollution to water and air supply
location of development
developing on a previously developed site
providing native plant vegetation
providing pervious paving
reducing storm water runoff
treating storm water
reducing heat island effects
eliminating light pollution
providing easy access to transit facilities
selection of site materials to eliminate heat island effects
water efficiency
_reduce the amount of potable water used for irrigation or disposal
collecting storm water for irrigation
provide low flow faucets, shower heads
prevent ground water consumption
energy & atmosphere
_reduce the amount of energy consumed
_production of energy creates green house gases
select energy efficient lighting, heating and cooling systems, receptacles,
use onsite renewable energy systems to reduce the dependence on fossil fuels
commissioning ensures that the building systems are operating as projected
help to reduce the ozone depletion and use of renewable power systems
materials & resources
_reduce the impact of material selection on the environment
location of the manufacturing process
energy required for manufacture, transportation
product durabilityoff gassing during manufacture and during installation
recyclability after its use
purchase costs
raw material renewability
materials & resources
_chart used by architects to determine the sustainability of the products selected
_used Athena EcoCalculator to help
indoor environmentalquality
_reduce the amount of pollutants in the indoor environment
monitor indoor air levels
ensure the air supply is clean
ensure mechanical systems are working properly
eliminate moisture problems
provide views of the outdoors from the interior
provide daylighting accessibility
provide thermal comfort
specify materials with low VOC’s or little off gassing effects
optimizing the fresh air intake
innovation & design process
_reduce the amount of pollutants in the indoor environment
earth tube system
heliostats bring in daylight to areas that are not adjacent to the building shell
use ‘green housekeeping’ that does not produce toxic gases
use 100% green power
areas of improvement
_stormwater management, onsite treatment beneficial to the environment
a great visual learning experience for university students
Sidwell Friends Middle School in Washington, D.C. designed a wetland in a central courtyard that treats storm water runoff and waste water on site.
areas of improvement
_EA controllability of systems
Perimeter Spaces and Non-Perimeter Spaces to be controlled by users.
Because EEEL is an institution, providing control of heating or cooling systems to students may be misused.
areas of improvement
_non LEED suggestions
photovoltaics
extend lifespan of buildings to more than 75 years
implement more passive mechanical systems that can be used year round
building to relate to the site – shape, form, size, materials, color
green roof
salvage materials from other locations
alternative construction techniques
conclusion
we need to be the first to change. others will follow
we realize that we are not very conscious about how much natural resources we use or how we impact the natural environment by pollution
EEEL is the future of building practices
LEED is only a minimum standard
= lower operating costs and increased productivity
conclusion
“To move the world, we must first move ourselves’ — Socrates.”
“If we think of providing sustainable workplaces as a service, rather than as a commodity, we will build what is most economical for us to maintain and operate, and easiest for occupants to comfortably and productively use.” –William McDonough.
"The world will not evolve past its current state of crisis by using the same thinking that created the situation."- Albert Einstein
