Green Building Materials - moladi moladi - Green Building Materials Green Building Materials Embodied Enegrgy: " Embodied energy  is the sum of all the energy required to produce any goods" Refering to the above chart reflecting the energy required to produce a kilogram of raw material in MJ/kg - it is obvious that aluminium consumes the most energy during the production cycle wheras cement per kg is much lower.  The higher the energy cost the higher the cost of product - e.g. Sand to Glass or Bauxite to Aluminium - That is why  moladi   is the most cost effective way to build #green.

Embodied Energy in Construction Material

Image
Embodied Energy in Construction Material-moladi   Embodied Energy in Construction Materials Embodied Energy Embodied Energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy-saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in deciding whether a product contributes to or mitigates global warming. One fundamental question is: does the device produce more energy or save more energy than it took to make it? Embodied energy is an accounting method which aims to find the sum total of the energy necessary for an entire product life-cycle. Determining what constitutes this life-cycle includes assessing the relevance and extent of energy into raw material extraction, transport, manufactur...

Increased temperature - Thermal mass vs. lightweight timber homes

Increased temperature - The Concrete Centre embodied energy-moladi When taking account of the environmental sustainability of a construction material it is disingenuous to consider only its embodied carbon dioxide. Embodied CO2 is only part of the story. Embodied CO2 is considered a useful metric for comparing the global warming potential (GWP) of different construction materials. Based upon the extraction and transportation of raw materials and their manufacture into the final product, embodied CO2 is expressed as CO2 per unit mass (kgCO2/tonne) or CO2 per unit area for a completed building (kgCO2/m3). Interestingly, once issues such as raw material transportation are taken into account, the misconceptions about the embodied CO2 of different construction materials are made apparent ( see table: embodied carbon dioxide and construction materials ). However, when considering the sustainability of a construction material you need to look beyond the material's initial em...

Housing construction costs in Yemen: Affordability & Purchasing Power - Middle East News

Housing construction costs in Yemen: Affordability & Purchasing Power - Middle East News : The substantial problem of a housing shortage is becoming an enduring feature in Yemen. All the same, the response to housing needs was hasty. Construction projects were executed using inappropriate and costly construction and design practices resulting in low-quality housing, causing further escalation in construction and housing costs to prices beyond the financial reach of the majority of the population in Yemen. A report by Dr. Basel Sultan.Improving the construction and housing sector is essential for several reasons. First for economic reasons, the performance of the construction & housing sector has a considerable influence on the overall economy where it contributes seven to 15 percent of the Gross National Product (GNP). Secondly, for social reasons, because housing is a basic human need. Third, for environmental reasons in order to reduce the consumption of resources, especially...

What is the cost to 3D print a house?

What is the cost to 3D print a house? What is the cost to 3D print a house or rather the "walls" of a house? What is the cost to 3D print the walls of a house? Whenever there is a post regarding 3D printing of homes, we are tagged by friends and colleagues to respond to the advantages of moladi vs 3D Printing. We therefore want to make it quite clear that this post is published purely to summarise our take on the topic and to have the ability to reference these questions and statements without having to repeat what we see as inherent issues associated with the 3D printing process of houses. All of the numbers used for 3D printing cost purposes are assumed, as these cost are not readily available for the purpose of this cost example. We would invite any 3D printing entity to help with the actual numbers to take any guesswork out of the cost estimation. First 3D printing post in 2017:  3D Printing a house or is it in reality - 3D Printing Walls?    - Link The de...

Moladi reduces high costs of conventional building techniques through new technology

Moladi reduces high costs of conventional building techniques through new technology Moladi reduces high costs of conventional building techniques through new technology New moladi construction technology Africa is a rapidly urbanising continent, which according to the UN Habitat, is increasing at a rate of 230,000 people who are moving into cities across Africa each week. Currently, sub-Saharan Africa alone has an estimated housing deficit of 30 million units and every year, the backlog of houses across Africa’s 54 countries collectively increases by 4 million houses. With the population of the African continent expected to reach a staggering 2 billion people by 2050, almost twice the population number estimated in 2010, it is a stark reality that every year, there will be more and more people needing homes, over and above the current demand.  reduce cost of housing construction Although the extensive and many complex difficulties, relating to the delivery of a...
