A window is an opening designed or created in the wall or any surface exposed to external environment to admit daylight, facilitate cross ventilation and contribute to thermal comfort conditions. This paper deals exclusively about drawing adequate daylight to internal spaces from available day light outside. It is analysed and found that the appropriate proportions of sizes, proper location to achieve uniform spread of daylight and penetration levels. The spread of day light intensity related contours have been analysed on horizontal working plane at 0.75 m from the finished floor level in a room size of 6.0 m*4.0 m through a building code method and simulation and it was found that the size and location of windows are appropriate enough to illuminate the daylight with proper spread and distribution in Vijayawada region of Andhra Pradesh in India. It was also assessed that window of the same size can be split in to two windows and placing at side by side walls/vertical planes was more effective in spread/distribution of day light on working plane. The day lighting considerations in this region are essential for saving the energy and sustainability.

Protection of historical buildings is an important international task. Historical buildings, in addition to aging wear, are subjected to periodic and continuous dynamic effects from earthquakes and passing by road and rail transport and from effects of exhaust gases. Most historical objects are constructively made of local materials: adobe, brick and stone blocks, they have mixed structural schemes and do not possess the necessary seismic resistance. The authors of this article propose the technology of dynamic and geophysical testing of structures for assessing the category of technical condition and seismic stability. This article gives examples of the application of this technology to assess the state of historical objects.

Due to the fact that a building resistance against explosion waves depends on a range of factors, including the shape and form of the building, number of opens and building materials used in construction as direct factors, distance and number of barriers between building and the location of the explosion as indirect factors. And because external cover of the building as the most important line of defense to protect against external threats, with taken into account that explosion waves can damage the building through the pores in the external cover or destroying the outer shell of the building. It is important to design resistant building facades in front of explosion consequences. The main goal of this paper is to assess the responsiveness of modern architectural facade to the passive defense requirements to be observed a way that if an explosion occurred outside the building and on the surface of the earth, the waves of pressure cause the lowest damage available to the exterior surfaces of buildings. In the studied model we note the following weaknesses: the inability to take advantage of the green element in the site, the misuse of some glass decorative elements in the balconies, the excessive opening in the facade in general and the use of the large opening without dividing in the stair space. Entrances are gone deep inside the facade where the advanced entrances are recommended to maintain the possibility of exit in the event of ruin. In the end, more dynamic shape may be better.

Reducing negative impact on building and the natural environment is the main objective of sustainable design that promotes the environmental quality and the quality of building, which is mainly related to the envelope design of the building. Hence, the main research problem is determining the building envelope shape effect, whether curved or tilted, so as to be more effective in the location of solar cells on its surface and measure the efficiency of each; therefore, the study model could be divided into the design of the building envelope (independent variable) and solar absorption efficiency (variable dependent) where the basic criterion will be environmental suitability and sustainability. Methodology of the study will be based on the theoretical study, the collection of information and descriptive analytical method, in addition to the practical approach and the use of simulation software programs to reach the most important conclusions and recommendations.

This paper uses the objectives and policies inherent in the New Zealand Coastal Policy Statement 2010 as a template for benchmarking the adaptation strategies contained in the Unitary Plan for Auckland City, New Zealand’s largest coastal municipal centre. The research analyses the stakeholder feedback from the public submission section devoted to coastal hazards, and assesses through selected criteria and a rating system, developed in conjunction with literature studies and stakeholder contribution, the degree to which the plan aligns with the policies of adaptation required by this Coastal Policy Statement. A case study tests the effectiveness of the adaptation requirements. Results indicate an appropriate degree of compliance with the relevant adaptation criteria, but that, in order to minimise future disruption, more attention should be given to the long-term planned withdrawal of housing from hazardous coastal situations.

This paper intends to study the possibility of producing fiber recycled self-compacting concrete (FRSCC) using demolitions concrete as a coarse aggregate. Polypropylene fibers (P.P.F) were used in recycled self-compacting concrete (RSCC) with different percentages of coarse recycled concrete aggregate. Nine concrete mixtures were set up to accomplish the objective proposed at this paper. Polypropylene fibers fraction changed from 0% to 0.15% by the volume of concrete and the ratio replacement of recycled coarse aggregate with natural aggregate was 25%, 50%, 75%, and 100%. The fresh properties of (FRSCC) and (RSCC) were assessed utilizing V-funnel, L-box and slump flow tests. Flexural strength, compression strength, and tensile strength tests were performed with a specific end goal to examine mechanical properties. The results indicate that the optimum volume fraction of polypropylene fibers was (0.1%) for the mixes contained recycled coarse aggregate (75%), for optimum content of (P.P.F), the compression strength, flexural strength, and splitting tensile strength; improved by (34%), (14%), and (8.1%), respectively with consideration to control mix. Also the flexural strength and the tensile strength for the mixes were improved with increasing the fibers ratio compared with control mix

The Himalayan region is, one of the most seismically vulnerable and tectonically active zones in the world. Sikkim is a state in North-East India, situated on the Himalayan arc. Sikkim is dotted with numerous Buddhist monasteries dating back to the 17th century. These historical monastery structures are a part of the rich cultural heritage of the state, being structures of social, cultural and religious significance to the community. The old monasteries are typically load bearing structures where stone masonry and timber are used extensively as columns, beams, floors, roofs and also in staircases. The monasteries follow some spatial characteristics such as regular geometrical shapes in plan with an assembly hall and front verandah, and are usually one or two storeys high with diminishing upper storeys topped by light weight sloped roofs. The M6.9 earthquake on September 18, 2011, in Sikkim has clearly demonstrated the vulnerability of the historical monastery structures. The evaluation of the earthquake vulnerability of monasteries is a necessary first step for their protection in future earthquakes. This paper analyzes the performance of one of the non-engineered monastery structure made with load bearing stone masonry - the century old hilltop Hee Gyathang Monastery located in the North District about 30 kms from Mangan. Structural analysis by demand capacity method of this monastery proves that the monastery is unsafe after the 2011 M 6.9 Sikkim Earthquake.
