BSD-005: Green Building and Sustainability — Building Science Information

BSD-005: Green Building and Sustainability — Building Science Information | Green Building Design - Architecture & Engineering | Scoop.it
The construction and operation of buildings consumes over a third of the world’s energy consumption, and 40% of all the mined resources.

 

"In more practical terms, this means that a sustainable building cannot, in construction, operation, or disposal:

 

-consume materials unless they can be easily and harmlessly extracted, used, and returned to nature,

-consume non-renewable energy,

-destroy natural habitat, bio-diversity, or bio-mass, or

-release pollutants of a type or quantity that cannot be harmlessly broken down by natural systems.

 

These are very difficult criteria to meet, and in fact require all aspects of human activity to be changed to meet them. For example, until steel is recycled in a non-polluting manner using renewable energy sources, no steel of any type (including nails or screws) can be included in a truly sustainable building. Clearly we are very far from producing even a single truly sustainable building in the industrialized world. However, to move toward these goals is both possible and practical."

Sustainability of the Building Envelope | Whole Building Design Guide | Green Building Design - Architecture & Engineering | Scoop.it

 

"For the design, construction and operation of a facility, there is an especially important interface between the indoor and outdoor environments, that of the building envelope. The building envelope is comprised of the outer elements of a building—foundations, walls, roof, windows, doors and floors. The prime functions of the building envelope are to provide shelter, security, solar and thermal control, moisture control, indoor air quality control, access to daylight, and views to outside, fire resistance, acoustics, cost effectiveness and aesthetics."

"Our climate is very cold and moist, for this reason the indoor grey water garden is designed to move water though it quickly rather than to act as a holding cell. The garden is isolated on the west side of the house, along with a bathroom, rather than across the front of the house. This will make it easy to control the humidity levels of that part of the house, whilst allowing the rest of the house to be opened up with a 2 level high ceiling and loft area. The second floor will sit about 8 feet behind the first on a secondary rock shelf that was carved out 9' 6" higher than the bottom platform."

Solar geoengineering may be feasible and affordable [But is it a Good Idea? please comment]

Solar geoengineering may be feasible and affordable [But is it a Good Idea? please comment] | Green Building Design - Architecture & Engineering | Scoop.it

A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.

Put into context, the cost of reducing carbon dioxide emissions is currently estimated to be between 0.2 and 2.5 per cent of GDP in the year 2030, which is equivalent to roughly USD $200 to $2000 billion.

Solar radiation management (SRM) looks to induce the effects similar to those observed after volcanic eruptions; however, the authors state that it is not a preferred strategy and that such a claim could only be made after the thorough investigation of the implications, risks and costs associated with these issues.

How Energy Shapes the Economy

How Energy Shapes the Economy | Green Building Design - Architecture & Engineering | Scoop.it

"In the beginning, the Master Economist created the Economy.  He created businesses large and small, consumers, governments with their regulation, and financial institutions of all types. And the Master Economist declared that the economy should grow. And it did grow, but only for a while. Then it stalled. Then He declared that stimulus of various types should fix it, and it did, for a while. Then He declared that if humans would just wait for a while, it would fix itself, but it wouldn’t."

BSD-013: Rain Control in Buildings — Building Science Information

BSD-013: Rain Control in Buildings — Building Science Information | Green Building Design - Architecture & Engineering | Scoop.it


Moisture is one of the most important agents leading to building enclosure deterioration.



"2. Drainage/Storage/Exclusion

Siting, building shape, and surface rainwater control rarely provide complete rain control in rainy climates (although deep, wrap around porches may eliminate the need for rain control under them). Hence, some strategy to deal with the rainwater that penetrates the surface of the wall must be employed. There are three fundamental rain control strategies available to the designer [11]. In order of historical priority, they are:

Storage (storage or mass walls),Exclusion (perfect barrier walls), andDrainage (drained and screened walls)."

Update on PlayPumps Technology

Update on PlayPumps Technology | Green Building Design - Architecture & Engineering | Scoop.it

Water For People helps people in developing countries improve their quality of life by supporting the development of locally sustainable drinking water resources, sanitation facilities and hygiene education programs.

"A year of Play Pumps in the fieldBy the time of Water For People’s roll-out in 2010, concerns about Play Pumps had been documented across the development sector in Africa. Water For People welcomed the chance to address these challenges with innovations in functionality and safety, and in approaches to management and maintenance. All of these have been pursued in good faith over the past year.

 

Following are the highlights of that effort:

A Play Pump cannot provide water for an entire community....

....

The Play Pump storage tank was not user-friendly."

Geo-Engineering Regulation House of Commons

House of commons-UK  Report on Geo-engineering Chemtrails & Weather Modification...

 

"Geoengineering describes activities specifically and deliberately designed to effect a changein the global climate with the aim of minimising or reversing anthropogenic (that is humancaused) climate change."

"There are three reasons why, we believe, regulation is needed. First, in the future somegeoengineering techniques may allow a single country unilaterally to affect the climate. "

Architecture and the Lost Art of Drawing

Architecture and the Lost Art of Drawing | Green Building Design - Architecture & Engineering | Scoop.it
The computer is encroaching on the most powerful tool in architecture: drawing.

 

"The computer, of course. With its tremendous ability to organize and present data, the computer is transforming every aspect of how architects work, from sketching their first impressions of an idea to creating complex construction documents for contractors."

 

"Today architects typically use computer-aided design software with names like AutoCAD and Revit, a tool for “building information modeling.” Buildings are no longer just designed visually and spatially; they are “computed” via interconnected databases. "
