The main study you refer to is very interesting, especially when they talk about how
embodied energy of solar panels is calculated.
They offer sustainable solutions with
low embodied energy, reduced waste and minimal carbon emissions — all factors that can help save our planet for future generations.
This report describes
embodied energy for cellular base stations, which is a major part of the electricity used for the cellular network.
With their study the researchers provide an innovative and comprehensive global analysis of
embodied energy use and indirect greenhouse gas emissions — from all relevant power sector technologies.
Reducing
embodied energy costs, increasing efficiency and increasing depth of discharge will also further improve the energetic performance of batteries.
The problem is that traditional materials generally contain much
less embodied energy per pound than the high - tech ones.
It is a lot easier pay back the loan if you don't use materials with
high embodied energy like concrete, plastic or aluminum.
And we will also be talking about embodied water, water footprints, or virtual water, as much as we are talking
about embodied energy or carbon, or carbon footprints.
Further, as the life cycle is increased beyond 50 years to 100 years, the
recurring embodied energy can eventually exceed operating energy in buildings with low operating energy demands.
These factors will
reduce embodied energy through improved durability and lifespan and will greatly reduce energy use for space conditioning.
You may notice that I have not
mentioned embodied energy, green building materials, or improved indoor environmental quality at all.
Forty percent on an annual basis is attributed to building operations; 8 % is attributed to building the buildings, what I talked about
as embodied energy.
Most of the energy and materials consumed by a device is consumed during the manufacturing process,
called embodied energy.
The traditional argument has been that
embodied energy doesn't matter much over the life of a building and that it is much more important to save operating energy.
From heating our homes to operating our businesses, to lighting our roads, anything we use and
consume embodies energy.
What counts is total energy consumption:
embodied energy + energy consumption during the use phase.
Of all the green conferences I've attended, it's the first time that I've
seen embodied energy labels in bathrooms.
Perhaps I have been taking the wrong approach all this time, promoting natural materials with
low embodied energy.
We often complain that there is a lot of
embodied energy in existing buildings and that they should be preserved and renovated; we have also repeated Donovan Rypkema's comment that architects are overly fond of «green gizmos» instead of simpler
According to the press release it will «demonstrate how to transform this challenging building stock into a prototype of ultra-efficiency that will use no HVAC system, no electric light use during the day, 100 % ventilation, almost zero energy, and produce zero carbon emissions,
including embodied energy of materials.»
Meanwhile Breeam, and its emphasis on using low
embodied energy materials, led the design team away from steel and towards timber.
I have dreams of only wearing chiffon dresses that
embody energy from the 60», 70's, running around barefoot and living in a bungalow house on Laurel Canyon.
In addition,
embodied energy calculations are almost never done conclusively, really looking at EVERY material that goes into a building, and the localised variations in the procurement chain (eg aluminium in NZ is produced with 100 % hydro electricity), but rather picking and choosing structure, insulation and whatever else is de rigueur.
In addition to this, the remaining films also question familial relationships, time and place, but they
also embody the energy, capacity for change, as well as the character of this celebrated location.
Its production is efficient too: the cellulose is derived from 85 % recycled paper products, and manufacturing plants nationwide cut transportation requirements, and therefore the
overall embodied energy of the product.
Annualized embodied / manufacturing energy to produce tablet (details in this report) ~ 100 kWh / year per tablet, and cell network operating energy equals
annualized embodied energy of network equipment used for 5 years.
Once you are building to such a high energy efficiency standard,
embodied energy really matters, and I continue to believe that it should be part of every Passivhaus designer's toolkit; I think it should be built right into their giant spreadsheet.
The difference between the two totals (125kWhp / d / p and 195kWhp / d / p) is identified on p116 — for example the lower total
excludes embodied energy in imported goods.
Located in midtown and inspired by each city block, Aldo Sohm Wine
Bar embodies the energy of New York with the laid back atmosphere of Aldo's own living room.
Bringing a corner of Nashville to the center of Manhattan, Printers
Alley embodies the energy and laid - back charm of the south.
By refurbishing the building modules and preserving these elements which have
significant embodied energy, Foremans is extending the life of the building.
That's the
full embodied energy in all the materials and construction equipment and trucks doing deliveries for the construction of the building, paid back over the estimated 60 year life of the building, generated through self - produced solar, wind, and cooling from the sea, air or the ground via heat pump.
But anything that makes bike maintenance accessible and easy for the masses is likely to be a boon for sustainability, given the
relative embodied energy in a bike, compared to a pipe cleaner.
The Nirvana of Zero - Zero — energy efficiency and low
embodied energy by Gareth Roberts (Sturgis Carbon Profiling)
► Embodied energy is the energy used to produce a material substance (such as processed metals or building materials), taking into account energy used at the manufacturing facility (zero order), energy used in producing the materials that are used in the manufacturing facility (first order), and so on.
When the entire existing global building sector — 1.49 trillion square feet — is taken into account, annual building operations energy consumption and GHG emissions greatly exceeds the
annual embodied energy and emissions of new construction.
This means that, in 2030, the 900 billion square feet of global floor space constructed from 2015 to 2030 will be heavily weighted
toward embodied energy and associated GHG emissions (embodied carbon).
I am not arguing to
neglect embodied energy altogether, but to either do it right, which is a hell of a lot of work, or to simply adhere to some rules of thumb.
