Energy consumed by materials like brick, tile, steel, glass accounts for 50% of the global energy and 50% water resources, 40% raw materials, 80% agricultural land loss producing 50% of air pollution, 42% greenhouse gases, 50% water pollution, 48% solid waste, 50% the CFC compounds "[2].
It is the optimization of glass greenhouse, buoyancy ventilation, solar water heating, skylights, lighting and other technology.
Green residential design provides a healthy and comfortable environment for human beings and saves resources like energy, land, water and materials).

GLP project was sponsored by local government, and its project team included of related departments and professional elites, showed a high level of internal support, coordination and cooperation.
This project can protect effectively water safety and restores water environment.
These areas were analyzed to identify its many components from water sensitivity zones and sensitive biological areas.
These protection strategies in first phase of work included: -Protecting natural water resources and conserve potable water; -Integrating natural resources such as mountain, water, farmland, wood, etc.; -Maximizing diversion of waste from village; -Conservation, restoration and enhancement of ecological habitat to reflect the local natural heritage and enhance biodiversity.

Experiments have been performed to determine the value of the arc breaking length of electrodes when welding under water.
Paraffin is applied for the purpose of electric and water proof reasons.
The process of bead forming under the water.
Welding arc is ignited under water and burns to a natural breakup.
The welding operator should be a high-quality professional. 3 The best elasticity of the welding arc for underwater "wet" welding is recorded for EPS-AN1 electrodes; UW-EZ-2 electrodes by BrocoUnderwater have good elasticity, and LKI-1P have the worst one (because of the high content of fluorides).

Then, the temperature of the alloy liquid cooled to the given pouring temperature, and the alloy liquid was poured into the water-cooled serpentine channel.
After that, the collective mold with slurry was rapidly placed in a water pool within 2~3 seconds to retain the slurry microstructure at high temperature as far as possible.
The water-cooled copper serpentine pouring channel had three curves along the inner channel.
The area A and the perimeter P of every primary silicon grain on a photo were automatically measured by a professional image analysis software.
When A390 alloy liquid is poured into the water-cooled copper serpentine pouring channel, the superheated liquid will flow down along the inner wall of the channel.

It is speculated that antimony could be a natural contaminant with arsenic in some drinking waters.
The prepared samples were placed on a water bath constant-temperature oscillator at 200 rpm at 25 ℃.

Drug Center Co., Bangkok, Thailand) was used as surfactant for water phase.
The water phase was prepared by adding the water soluble ingredients and heated in the water bath to 75ºC.
The water phase was added into oil phase and mixed using a homogenizer for 5 min at 6000 rpm.
pH value and rheological behavior determination. pH value of creams was measured using a pH meter (Professional Meter PP-15 Sartorius, Goettingen, Germany).

When mixing mortar with new and innovation material, property specification which classifies mortar by performance (compressive strength, water retention, and air content) is preferable [8].
The cement-to-fine aggregate ratio was 1:3 (by weight), and cement for construction professionals CEM II/B-L 32.5 R was used.
Sandy clay was dried naturally under the sunlight for one to two days to ensure there is no any effect on water- cement ratio during mix design.
According to BS [18], the mixing proportion of the cement and fine sand for mortar is 1:3, while water content was determined based on workability test.
All specimens were cured under the water until the testing age, which is 7, 14 and 28 days.

The research aims to provide valuable insights for engineers, architects, and construction professionals interested in sustainable materials, offering a comprehensive understanding of the challenges and advantages associated with recycled concrete in high-temperature environments.
This strategy not only reduces the demand for natural resources, such as gravel and sand extraction, but also minimizes the amount of construction and demolition waste that ends up in landfills, thus contributing to the reduction of soil and water pollution [16].
When the aggregates are extracted from the quarries, environmental problems are caused, such as geological erosion, water and air pollution, vibration, noise and modification of the landscape or environment.
The plasticizing admixture was used to reduce the amount of water in the mix.
This method consists of subjecting the recycled aggregate to hydrochloric acid for 24 hours to then separate the adhered mortar by washing with water.

The investigation items cover 11 classes including water supply, drainage, power supply, house quality, outdoor environment, transportation, air supply and planning.
The investigation showed us that 40% of the villages had no tap water supply, 75% drilled wells near cesspool or lavatory for water, 40% of that outgoing is difficult in rainy days;60% had no public places for gathering, 70% animals’ hovel mixed with people’s houses, 80% had no library, and 90% of that garbage was abandoned optionally.
No condensation Fig 2 Moisture sorption isotherm of raw soil material Raw soil is a kind of porous material and its resistance to water vapor permeation is small so moisture can diffuse from the stressful side to another side easily.
So as an architect we should make good use of our professional knowledge to direct the design and regeneration of new adobe buildings and improve their indoor environment.
