Which method is most efficient for mortar removal from RCA?
Relevant answer
Answer
The use of an impact crusher as a secondary crusher is recommended when the RCA particles require less adhered cement-paste (Silva et al. 2014). Snyder et al. (2018) reports the use of a jaw crusher reduces the amount of fines produced, as compared to core and impact crushers.

Do construction professionals (especially construction managers, project managers and quantity surveyors) need environmental sustainability competencies?
Looking at how the construction activities affect the environment and yes we have environmental engineers but wouldn't it be good to have construction professionals that are also aware of the environmental impacts/issues, especially during the construction, operation and demolition phases.
Assistance will be appreciated.

Bontle Chabaesele The construction industry contributes nearly 1 billion tonnes of waste every year and also contributes to about 37% of CO2 emissions. Sustainability, Green construction, Environmental Impact Assessments (EIA) and minimizing the impact are the norms of the day and these cannot be called needed knowledge areas anymore. Now these need to be the core requirements for construction professionals

Hi,
While each of the 4 main criteria can include many sub-criteria, this question is about how companies in real-world projects set boundaries between them in their documentations (submittals and reports). For example, the training of project people criterion is it reported in the cost, or the quality, or the sustainability. Are there any references for these boundaries? With my very limited experience, I think tools like BREEAM and ISO are not clear enough for me as an academic student to help setting up such boundaries.
Please, can you indicate if your answer is based on project experience in this field?
Thank you very much beforehand.

Answer
Badeel Almahdawiy there are many ways and surely the experts have tried to answer and I am impressed with the answers above laid by the experts as they have nailed it., However I do feel strongly about such points which I have listed below and these are quite helpful when you want to set boundaries between cost, time, quality, and sustainability .... and you can say there are simple five ways where the impact by making more sustainable projects can be seen such as:
Reduction in the overall fuel consumption and this has to be reduced drastically
Designs of the buildings have to be Environmental friendly and conscious
Waste treatment methods should be scientific
There should not be any type of pollution
The material used has to be in the form of sustainable material and hope so this is in line with your requirement

Hi dear Divyesh.
Today, the growing need of society for buildings and housing, the need to use new building systems and materials to increase the speed of construction, lightening, increase useful life and earthquake resistance of buildings has become more and more. In this regard, upgrading the scientific and professional level of the engineering community and familiarity with new systems and building materials in order to apply these systems, is inevitable. Solving problems such as long construction time, low useful life or high cost of construction of buildings in the housing sector requires the provision of solutions for practical use of new building systems and new building materials to reduce weight, reduce construction time, more durability and ultimately reduce costs. Is run. These measures are considered essential for sustainable development. Also, in the long run, these efforts will reduce the waste of construction materials and consequently meet environmental needs, optimize construction, increase housing production and achieve optimal operating conditions. On the other hand, such developments will lead to the expansion of infrastructure investments in the housing sector, especially by the private sector, which will help governments achieve their housing goals.

Dear Dariusz Prokopowicz the sustainability criteria must be the core of our efforts to maintain our course towards a climate-resilient low-carbon transition, rather than continue the vicious cycle of environmental degradation, biodiversity loss, and zoonotic infectious disease outbreaks. For instance, the world response to the COVID-19 pandemic must be focused on addressing underlying factors through the SDGs to recover prosperity and restructure our society in a healthier, safer, fairer, and sustainable path. The option for a brown recovery instead of investing in a sustainable growth will depend on how human society will deal with the emerging risks from the COVID-19 pandemic. Kind regards, Ernani

Numerous research works have been conducted on development of sustainable materials and methods in construction technology. However, ground reality is that only few users have adopted such materials and methods.
Though sustainable development is the crucial need in construction industry, it has not been acknowledged and implemented in letter and spirit.
How can we overcome this challenge?
How can we convince the users regarding the benefits?
How can this be brought to ground from paper?
Relevant answer
Answer
Good evening,
I would suggest that the development and use of sustainable materials in construction technology is dependent on a number of factors like:
  • Building Regulations and Technology (e.g., if there is a requirements for a building construction to achieve a particular U-value, there would be a need to introduce insulation materials that would support this achievement).
  • Investment in research and innovation (e.g., investment of this nature can support development of local sustainable materials based on historic local tradition or new materials based on local waste or row materials; this could include financial support for change of existing construction materials manufacturing processes in favor of production of sustainable materials).
  • Education (e.g., education of professional and general public about the benefits of sustainable materials, where the use of sustainable materials become consumer preference).
  • Financial incentives (e.g., where use of sustainable material is potentially subsidized at least for a period of time until the sustainable materials become prevalent on the market).
  • External funding requirements (e.g., external funding for the construction process could be conditioned by the use of a certain percentage of sustainable materials on the project).
  • Introduction of local eco-ratings (e.g., where local construction materials can be rated based on their ecological impact; then these achieving certain ratings of materials or building can be linked with availability of government funding, etc.)
These are probably some of the ways how the use of sustainable construction materials might be promoted.

Its no new research that several studies have explored the use of alkali activated materials and geopolymer as a sustainable replacement to the conventional ordinary Portland cement. However, the sustainability of these materials is relative as it depends mainly on the availability of materials locally which eliminates the huge emission and cost associated with the transportation of both the raw materials and finished products. Therefore, the use of OPC might still be sustainable in some parts of the world compared to alkali activated materials and geopolymers
Relevant answer
Answer
The only real universal sustainable solution is not producing concrete.
In the comparison of binders, you have to look specifically to each location. Are you in a region where calcite and silicate minerals are abundant, but no producer of NaOH/Na-silicate or aluminosilicate can be found? In this case transport costs & footprint would shoot up for the alkali-activated material or geopolymer and might become less sustainable. In the situation of Belgium, which I know better, alkali-activated materials perform much better in comparison with Portland cement, because of the proximity of Na-silicate producers and the abundance of metallurgical residues.
Now, of course, there are other sustainable cements too, even OPC based systems, where the OPC is blended with high volume replacements of slag (blast furnace or others). In that case, comparing a 40%-60% blend (OPC-slag) with an alkali-activated material, the environmental gain is not that much anymore. Especially if you compare with geopolymer mixtures with metakaolin that you find in literature.
About the difference between geopolymers and alkali-activated materials, well, different definitions exist, which heat up discussions for some reason I never understand. So, just to be clear, the definition of alkali-activated material I used in this answer is "a material that becomes hard after mixing a powdered precursor and an alkali".
Cheerio,

My hypothesis is that the discourse of sustainability is a 'reflection' after a considerable/realisable 'damage'. Here, looking for historical positions on sustainability as a reflection in various socio-cultural-environmental practices/academia.
Relevant answer
Answer
The 20th century witnessed a paradigm shift in perceiving nature. The idea of environmental sustainability, including sustainable development and growth, is quite new, emerging in the second half of the 20th century. I am not aware of any similar ideas being driving forces of states' decision making prior to that.
The idea of 'sustainability' also requires foresight in the future, comprehensive planning for the future, an area that former (pre-20th century) way of thinking did not cover as it was more coined along the lines of ecological remedies. Additionally, although I do not challenge examples given here, I believe that decision-makers and overall government administrations anywhere in the world were considering sustainability as part of their agenda until the second half of the 20th century. Rise of the organisations such as UNESCO or IUCN after the WW2 can signify such shift, but then again, they were focused on nature protection and preservation, not on sustainability.
I believe that 'sustainability as an afterthought' is linked together to the general realization that anthropogenic influences really change the environmental quality in possibly irreversible way. This was realized, at least on international scene in 1970's when the Stockholm Declaration on the Human Environment was passed as a final document of the UN conference. This conference was called upon as an initiative of a Swedish government, so I suggest you can look for further information about the people behind it, it might prove useful as a starting point in examining the environmental-ideological discourse. Good luck!

what methodology we can use to select the sustainable materials from a set of materials for a particular region .
Relevant answer
Answer
One of the first creteria for choosing materials is the embodied energy, and it is usually co-rrelated to transportation costs (as well as production process), from the place of production of the materials to their final use; hence the use of local materials whenever possible is a sustainable practice. However it is necessary to be aware of the production proces of such materials, are they produced in a sustainable  way? do they gass-off? in this last point, you can find a wide range of materials such as paintings, glues, carpetings etc which are certified and have low or zero emmision of organic volatile compounds. This constitute another criteria for sustainable materials selection.
How will those materials will be disposed after their life cycle? are they reciclable? are the made of recicled materials? usually natural, low processed materials are more sustainable ones. Another recomendation is to look at the CO2 foot print of construction materials.
Given the wide range of perspectives for sustainability, it is understandable to be requested from you to take a stance of provide a definition of sustainable materials, however, in practical terms, you can down size the concept to availability, costs, and CO2 foot print (among others). Keep in mind that construction materials are elements of a whole which is the building and the way that you combine those materials will also have an impact on the potential to recycle them, making them more or less sustainable. That is why it is not an easy question.
Hope this helps and/or at least bring some ideas and key words for you to look at it in more depth.
Finally I want to remend you a book named 'Cradle to Cradle. Remaking the Way We Make Things'. It will help you to understand in more depth and have some examples related to the construction industry in the development of the concept

I had these apprehensions too about tall structures and so posted two questions regarding their design life and imposing limit on height to have control on maintenance apart from safety in this platform and unfortunately the questions had not got attention  so far!
The skyscrappers are being built, in my opinion, as prestige symbols by some countries like Dubai to claim possession of tallest structure and apparently getting revenues too from public, although it is not known whether  the maintenance is taken care purely from income generated from the Tower itself, as digital health monitoring of such skyscrappers is a compulsion for designed loads, while safety methods are not known due to fire and severe seismic intensities beyond design compulsions.
I happened to raise  query to a designer of Burj Khalifa in a conference regarding safety measures adapted to rescue the occupants from top floors in case of a fire, and I was told that they have to come down the stairs all the way!!
Wonder why safety chute systems cant be adapted in stages if we have to build skyscrappers, thereby high cost considerations  will certainly discourage developers over certain critical height of structures and compulsion of such safety measures act as a natural dampener on proposals of very tall structures!
The psychological factors of occupants of top floors also need to be assessed in case of general turbulences of these volatile structures and what guarantees the designer/developer are giving for their life time safety and whether such guarantees can be accecpted by any fraternity?

Dear Majid,
I think that one of the main issues is the continuity of the waterfront public promenade, its urban quality and its connection with the neighbouring programmes of commercial and residential urbanism as well as with public transportation. In such contexts, the work of urbanists, planners and architects has to integrate the micro-dimension of daily uses and trajectories as well as the more macro-dimension of the connection with the rest of the city. It is in my opinion this ability to play on both scales that allows (among other factors like the negociation with private developers of the extent and nature of public spaces) a project to acquire a specific value in terms of urbanity.

Can anyone say if they are better than the normal one story buildings because they take up less area?
Relevant answer
Answer
I think “high-rise buildings are subject to the effects of too much sun and too much wind on their all-glass skins. And all-glass skins are, despite many improvements to the technology, inherently inefficient. Glass is simply not very good at keeping excessive heat out, or desirable heat in. High-rises, according to BC Hydro (the province of British Columbia’s main electric utility) data, use almost twice as much energy per square metre as mid-rise structures.”
Moreover, high-rise buildings are less adaptable than mid-rise structures, and therefore are inherently less sustainable. Furthermore, , high-rise buildings are built largely of steel and concrete and are less sustainable than low rise and mid-rise buildings built largely of wood; steel and concrete produce a lot of GHG. Wood traps it. Concrete is 10 times more GHG-intensive than wood.

Hello Charlene
Land preservation and reclamation is currently the most usual technique against sea level rise. As you mentioned, Hong Kong and Japan are countries that the small size of their island states creates spatial needs to using reclamation techniques. Maldives exactly do the same about the sea level rise problem.
In my opinion reclamation technique includes large protection works of high cost and dubious results( they are sinking every year, as you said). So I think reclamation would not be an appropriate approach against sea level rise.

In some current Urban Forest  Strategies, the urban heat island effect is being a challenge and issue to the forest. Is it possible to improve it by landscape design of the forest?
Relevant answer
Answer
Hi Jing: To quantify the impacts, we use the following methods:
  • preference for landscapes with varying levels of green infrastructure
  • human reactions beyond preference to these same landscapes (e.g., stress reactions measured by self-reports, physiological tools like the ProComp Infinity 5, and hormonal measures for cortisol.
  • measures of attention (this grows from Kaplan's Attention Restoration Theory).
Hope this helps.

Embodied energy and building geometry that would create appropriate urban environment.
Relevant answer
Answer
The surface area to volume ratio (SA/V) or more precisely the form factor (SA/TFA) ratio of a building will strongly influence the payback time of any embodied energy in a building. There is a strong correlation between compact building forms and space heating and cooling energy requirements. Thus the economics will tend to favour more compact energy efficient forms, lower embodied carbon materials, and higher U-values. The optimum trade off between these factors will always be climate and building use specific however.

Energy Performance Analysis.
Relevant answer
Answer
The answers before do not seem to address the question, which is on how to do it, and how to promote it. There is some effort in the EU to try to improve the methodologies and the way energy efficiency is financed and promoted. Without proper information, there are no investors for this technology. Knowing the long term benefits is not enough, as customers very often do not want to invest fro longer term returns, or the returns are not 'owned' (e.g. tenants of buildings do not benefit from investing, owners do not pay the bills of tenants). New financing methods, aggregating projects to reduce the cost of the investment, and the creation of specialised funds to take the upfront costs are necessary. There is also a need to review in countries the regulatory framework, as energy efficiency in buildings is sometimes hampered by legal barriers, some of them rather illogical and unnecessary. I attach an overview document on some issues. I also add an example of an innovative approach by a consortium of companies and institutes for retrofitting public buildings and there is some information on how to calculate the benefits. The document is in fact to raise awareness and promote it.

In a thickly populated space where a piece of land is an exorbitant, but the landscape is pretty vital. What aspects are to be taken into consideration in order to design landscape in such areas and what would be the compromising aspects?
Relevant answer
Answer
In addition, the biography (heritage, layers of history) of that landscape as it exists would also be important to understand! It can also link the spatial planning to the landscape. Overall an integrated approach to spatial planning, one which includes the (historic) landscape and its natural and cultural values is important I think.

Are universities doing a disservice to their architecture students by focusing on design vs the Master Builder Architect focus? I have heard from many architecture professors that many schools are focusing on design more without much focus on students' comprehension of construction.
Relevant answer
Answer
To me it is totally truth. I had same experience and I've seen the same in many different schools of architecture in Latin America and Europe. To me is really unbelievable how design is treated independent from construction, considering that architecture, to be such, it has to be built. However in training architectural workshops (common format to teach architecture) you see design standing mostly by itself, without deep comprehension of how it has to be build up. I call that "paper architecture". I have to say that many professors love such things, they believe is a kind of "art". Unfortunately most of the time is no more than a nice drawing. Actually after finishing Ms in Architecture, I did not know but nothing about construction. I learned by doing when I built my own house. It has been so far the only work I've done as architect in my life anyway, because I was since always interested in cities. And here in this field I've seen another fact which still surprises me: architects advocating being in charge of cities. I've seen many colleagues doing urban planning without any understanding of urban process, and facing this complex discipline only as a "design" in a large scale. This is totally wrong and I think is playing against the prestige of the profesion. In my case everything I've done as urban planner I have learned in postgraduates studies, where you have to study a lot of things you can hardly learn in schools of architecture. Nowadays you see more and more that cities are becoming a matter of science. At the same time you see how architects are loosing their historical role within urban issues. Schools of architecture should take seriously this trend and reformulate their curriculums towards the future.

My interest is to do research on the means of using mud as a construction material more efficiently.
Relevant answer
Answer
In addition to the helpful response above, I would point out that adobe blocks are made with mud that has a high clay content as well as straw which is mixed in to make the block hold together better. The addition of siding such as vinyl siding on the outside of the adobe bricks will help protect the bricks from weathering. Lighter-weight materials such as tar shingles or plant-based thatch would ordinarily be used for the roof.

Dear Tong Kien: When the question is to improve the industrial recycling process, in my point of view, the best action to replace the qualitative visual procedure is to always give priority to a selective demolition. In RCD plants that I know, the only usual system (viable economically) is the separation of RCD components by sieving. When the identification of incompatible materials is necessary (ex: cement/gypsum), there are a lot of chemicals methods that could be employed. But, the technical and economical viability of any industrial recycling process is very dependent of a selective demolition otherwise we are in the utopia domain that is not a “beach for engineers”.

It is possible to intensify the use of soil triggering a new metabolism of the contemporary city?
Relevant answer
Answer
Camile:
In fact, the drivers of a cultural revolution are three: social sustainability, environmental sustainability and economic sustainability.
I believe that the evolution of any city is occurs as a function of the complex system of interactions established between the urban fabric and the economic, social and cultural fabric that fills and the models. The increasing complexity of these interactions, accelerated from the massive introduction of global transformations is that triggered the new metabolism of the contemporary city.
Today, a city to live needs to adopt a new philosophy of planning and management to ensure its sustainable development. Creating urban conditions, social, economic, cultural and environmental quality to live with in the cities of tomorrow, is thus one of the greatest challenges that we face.
The alternative is a model of sustainable development. A creative process and seeks a balance between all areas and only way to the development of living standards and conditions of nature, and for social justice, based on equity and economic and social sustainability. Just from a management process of this kind, can take decisions that meet the interests of today's citizens, without compromising those of future generations.
