Carbon Footprint Definitions
CARBON FOOTPRINT DEFINITIONS . What is carbon footprint? Carbon foot printing is a sub-set of a broader measure, the ecological footprint, which itself is a measure of the human demand on the Earth’s ecosystem and compares that demand to the Earth’s ecological capacity to regenerate resources and provide services. Carbon foot printing calculates ‘ the amount of GHG emissions caused by a particular activity or entity’ (British Standards Institution (BSI), 2008). This is commonly also referred to as global warming potential (GWP) and is measured in tonnes (or kilograms) of carbon dioxide equivalent (CO2eq.).
CARBON FOOTPRINT DEFINITIONS. What is embodied energy? Embodied energy is the energy consumed by all of the processes associated with the production of a building, from the mining and processing of natural resources to manufacturing, transport and product delivery.
CARBON FOOTPRINT DEFINITIONS. How does a tree store carbon?
CARBON FOOTPRINT OF TIMBER. Where does a tree store the carbon? Timber is a negative carbon footprint building material . For every 1 m ³ of pine at least 1 tonne of carbon is stored in the cellulose fibre of the timber.
CARBON FOOTPRINT TREND. Is carbon pollution really a BIG deal?
CARBON FOOTPRINT EFFECTS. Its not only about energy efficiency of your home; have you ever asked yourself what the environmental impact was of the material used to build your home?
Comparing Carbon Footprint of Different Materials CARBON EMISSIONS FROM THE CEMENT INDUSTRY • The cement industry accounts for around 5% of global CO2 emissions. • Cement production is growing by 2,5% annually, and is expected to rise from 2,55 billion tons in 2006 to 4,4 billion tons by 2050.

Energy Efficiency Definitions
ENERGY EFFICIENCY DEFINITIONS. What is Energy Efficiency? “Is simply the process of doing more with less to accomplish the same tasks and functions as before while using less energy”.
ENERGY EFFICIENCY DEFINITIONS. What is R-Value? Measurement of the thermal resistance of a material. The HIGHER the R-Value, of a material, the GREATER its insulating effectiveness. Around most of the world, R-values are given in SI units(physical units), typically square-meter kelvin per watt or (m 2 · K/W)
ENERGY EFFICIENCY DEFINITIONS. How we calculate heat loss? To find the heat loss per square meter, simply divide the temperature difference by the R-Value. i.e.: If the interior of a home is at 20 °C, and the roof cavity is at 10 °C, the temperature difference is 10 C° (= 10 K difference). Assuming a ceiling insulated to an R–Value of 2 (R = 2.0 m 2 K/W), the energy will be lost at a rate of 10 K/ 2 K · m 2 /W = 5 watts/per hr for every square meter of ceiling.
ENERGY EFFICIENCY DEFINITIONS. For the exact same temperature difference but with insulation of an R-Value of 1 the calculation will be as follows : If the interior of a home is at 20 °C, and the roof cavity is at 10 °C, the temperature difference is 10 C° (= 10 K difference). Assuming a ceiling is insulated to an R–Value of 1 (R = 1.0 m 2 K/W), the energy will be lost at a rate of 10 K/1 K · m 2 /W = 10 watts/per hr for every square meter of ceiling.

LET’S COMPARE DIFFERENT HOMES. BRICK & MORTAR HOMES vs TIMBER FRAME HOMES
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • Timber Homes are much quicker to build. i.e.: quicker turn around on investment.
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • Suspended Timber Homes may be built on difficult slanting building sites and are in many cases cheaper than brick & mortar and concrete homes.
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • In terms of durability, a correctly built timber frame structure has a significant life span, a strength-to-weight ratio that outperforms conventional building materials, and good performance under fire conditions.
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • For every cubic metre of timber, one ton of carbon is absorbed from the atmosphere.
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • This type of construction is unique in that it has the potential for carbon- neutrality, or even a negative carbon footprint, and is supported by trees, a renewable and sustainable resource if harvested from responsibly managed plantations.
OTHER REASONS WHY TIMBER HOMES ARE MORE CONVENTIONAL THAN OTHER METHODS: • With the solid backing of centuries of use, timber, as a building material, has stood the test of time. This reliability underpins its natural design flexibility, potential carbon neutrality, and gentle ecological footprint for a truly modern, forward-thinking construction material that is poised to serve an ever-growing market of environmentally conscious and responsible individuals.
WORLD WIDE TRENDS
WORLD WIDE TRENDS: • “Timber frame is expected to account for 27% of new housing in the UK by 2017, according to a new report.” REF: http://www.structuraltimberawards.co.uk/news/timber-frame-heading-for-27-new-housing-market-share/ • “ Back into the woods: global construction trends show that people are returning to wooden houses .” REF: Ideologist and creator of Dores Factory Egons Garklavs tells his recent observations in global construction trends that people are returning to wooden houses. • “The quarterly European Architectural Barometer survey of 1,200 architects across six European nations showed most architects expect the use of timber frames to increase over the next five years.” REF : http://www.building.co.uk/timber-frame-building-set-to-increase-say-architects/5041252.article
