Questions related to Building Technology
How can an energy independent home be built?
How can a zero-energy (energy-neutral) house be built?
How can a zero-emission and energy- and climate-neutral house be built?
What combination of energy efficient building technologies and renewable energy sources should be used to build a fully energy independent home?
What are the key priors for sustainable, environmentally friendly construction?
Various solutions are being used in the construction industry to reduce energy consumption and CO2 emissions into the atmosphere. New building materials are being used, as well as insulation materials for facades to reduce heat loss. Various renewable and emission-free energy sources are used (windmills, photovoltaic panels, others). Thermal (in winter) and/or cooling (during hot weather) energy-generating devices based on heat pumps, air conditioners, etc. are used.
What are currently known to be the most convenient, sustainable, energy-efficient and cost-effective combinations of applied energy-efficient building technologies and various, especially renewable/zero-emission energy sources in fully energy-independent houses?

What is your opinion on this subject?
I invite you all to discuss,
Thank you very much,
What can you say about building disassembly? For you, in you own opinion, is this method of construction in the present time effective and will it be develop through time?
I am an Architectural Engineering graduate student with a background in studying Building physics, Building materials, Building Services, and Building Technologies in sum. Remote sensing is not currently one of my strengths but I am shooting for an interdisciplinary topic to try to link the architectural engineering and remote sensing and widen the boundaries of building engineering.
Research in green building and smart building technologies is increasingly diversified and the limits between these practices are less and less defined. In this context I would like you to offer us your opinion. Thanks for your time and attention.
I used a frame structure to represent a continuous shell plate and this frame structure was calibrated with a physical model in order to have the same rigidity as the real one. However I was trying to identify how representative would if a change the thick of the frame elements to represent a shell plate.
Thank you in advance.
I'm looking for further information on occupant-centric retrofitting scenarios of non-domestic existing buildings.
Technical colleges are the institutions where craftsmen are trained to the craft level and awarded NABTEB certificate. The aim of technical college is to produce graduates with competent skills which could be put into practice to enable them become self reliant. In technical colleges, technical teachers give training on various disciplines such as electronics works, building technology, wood work technology, metal work technology, to mention a few.
Medical Equipment and tools are the machines, tools, equipment, testing instruments used for diagnosis of patient in the hospital
I am working on the resuspension of a fluorescent tagged oligonucelotide. I came across few protocols carrying out the process with either Tris-HCl or TE Buffer. The only difference in composition is the presence of EDTA. Would using either these two make a difference?
How to install over 1.8m colorbond wall?
I would like to instal colorbond to cover our site. However, according to wind speed, it is not available to build over 1.8m height. we pland to have a 2.4m colorbond but to do that, we need some kind of support or material which won't have demage even if wind is strong.
1. is there any calculation or formula that i need to use to calculate colobond maximum height?
2. what other material i can use to make 2.4m height?
The studies I have found are not very conclusive. A study of highway projects found that DBB projects took longer to deliver than Design-Build projects, although cost did not differ significantly. (Shrestha, P., O’Connor, J., and Gibson, G., Jr. (2012). "Performance Comparison of Large Design-Build and Design-Bid-Build Highway Projects." J. Constr. Eng. Manage., 10.1061/(ASCE)CO.1943-7862.0000390, 1-13.) Another study found that DBB either performed better than DB in meeting cost estimates, or performed about the same, depending upon the statistical method used; both were comparable at meeting project timelines (although DB is recognized to be faster). (Minchin, R., Jr., Li, X., Issa, R., and Vargas, G. (2013). "Comparison of Cost and Time Performance of Design-Build and Design-Bid-Build Delivery Systems in Florida." J. Constr. Eng. Manage., 10.1061/(ASCE)CO.1943-7862.0000746, 04013007.) And yet Design-Build is continually put forward by officials as a solution to excessive project costs. Are there any data to back this up?
Buildings commonly use a factor of safety of 2.0 for each structural member. The value for buildings is relatively low because the loads are well understood and most structures are redundant. Pressure vessels use 3.5 to 4.0, automobiles use 3.0..
Is there a good experimental way to protect the sandstone walls of the salts and the moisture in the historic buildings?? Please explain or share some ideas and documents.
I want to study the free oscillations of a 7-storey structure. Apply a displacement to external nodes of the tree by running "initial x disp" but nothing happens. I would like to deform the structure and let her go back to the equilibrium position but nothing happens. Can you tell me where I'm wrong? Maybe I should not use the initial command?
I am doing a research on parametric simulation of modular design of prefabricated components in buildings. I am looking for any standard or guideline on how to calibrate and standardize the size and specifications of modules for prefabricated components such as walls, floors and roofs. What I have found so far are some commercial catalogues that have no decent scientific values.
I would appreciate if the experts and researchers could introduce me any relevant sources of information.
I am just starting a research about building-related urban agriculture, and in particular farming practices taking place against/on/within the building envelope (rooftop and facades). Is there any literature about architectural and spatial integration of the farming rooms into building or, even better, about buildings' architectural requirements for a proper integration ?
Thank you in advance!
I have Young’s modulus of grout and its area,Young’s modulus of grouted sand and its area and Young’s modulus of steel casing and its area.
I am going to scale my 7 ground motion for rehabilitation of structure with base isolation. ASCE 7-10 (for new structure) is really explicit in defining period range (0.5Td-1.25Tm) for scaling ground motion to reach design spectra , but unfortunately ASCE 41-06 is very ambiguous about this range.in section 22.214.171.124 about nonlinear dynamic procedure , it referenced to section 3.3.4 , and there , it referenced to section 126.96.36.199 (where T for fix base structure is considered) .
in none of above section , there isn't any mention about modifying period range for base isolation structure.
can anyone help me.
i must mention that i should use ASCE 41-06 and i couldn't use ASCE41-13 or FEMA1050 or FEMA P-751.
the corresponding sections from ASCE 41-06 is presented in apendix
thanks for all , either responders or not.
What do you think if we propose a residential building envelope made of water which is non-toxic, fire resistant, recyclable, and low-cost with high specific heat? I am currently working on a proposal which water is the main structural element of my envelope prototype but I would like to know your feedback on this matter and any resources that might help.
After visiting Europe I noticed a major difference in Europe and America's construction methods, specifically in the residential area. It seemed majority of the homes in Europe were concrete masonry framed, unlike in America whereas most residential homes use wood framing. I would appreciate any input on why the construction is different.
As per IS 1893, Storey drift shall not exceed 0.004 times storey height. If it is exceeded, then how to minimize it for multi storied building.
Generally 5-10% cement (by weight of soil) is added to rammed. Is rammed earth sustainable with this level of cement use?
I found two building technologies for helping the sea level rising problem:
1. Seawater Greenhouse
2. Seawater desalination plants
and both of them have been implemented in different countries.
I would like to know is there any other new building technologies which has been implemented or is implementing at the moment that can help to combat with the sea level rising issues.
There are some future construction plans for dealing with the sea level rising issues such as Shimizu Corporation's (Japanese construction firm)'s latest project: Deep Sea Future City Concept- OCEAN SPIRAL.
U.S. students from University of Pennsylvania have come up with an idea to install waterproof membranes protecting the lower stories of Manhattan's buildings to protect against rising sea levels.
Airport noise nuisance is a negative impact on long term health problem for residents especially when it occurring near urban areas. Like many other noise nuisance, it may be ignored generally in practice. I am currently looking for reliable materials to understand how government and designer interventions work to establish optimal policy targets for this issue.
I'm looking into how agricultural architectural systems (vertical landscaping and farming) in highly polluted dense urban environments can reduce greenhouse gases within cities. Within this topic I will be looking at the use and growth of algae within facades to capture greenhouse gasses, the impact of vertical landscaping on air quality, and the potential for vegetated pockets within high rise structures to further filter surrounding air within dense urban environments.
If there are any suggestions as to how I could potentially undertake this topic or publications that you believe might be resourceful, it would be greatly appreciated.
The IMS system was developed by IMS Institute in the last century. In Cuba there are many building built with that system and we need information about test making of that system.
I am trying to asses and evaluate the flexibility of houses but I couldn't find a comprehensive method for it.
