Abstract: Energy consumption is an important factor of com-mutational power these days. Large scale energy consumption results in bad
system performance and high cost. To access frequently used data, we place it in Cache. Cache provides us opportunity to access that data in
a small time. Cache memory helps in retrieving data in minimum time improving the system performance and reducing power consumption.
Due to limited size of Cache, replacement algorithms used to make space for new data. There are many existing cache replacement
algorithms for example LRU, LFU, MRU, FIFO etc. Existing algorithms consume a lot of energy while replacing cold blocks of data.
Replacement algorithms are usually designed to reduce miss rate and increase hit rate. These algorithms replace cold blocks (not going to use
in future) and due to large number of cold blocks, they consume lot of energy. This paper proposes an energy and computation efficient cache
replacement algorithm that put only hot blocks in action instead of removing cold blocks. This paper also discusses different replacement
algorithms proposed in different papers and compare these algorithms on basis of different parameters mainly energy consumption. In our
experiments we have found LRU and FIFO as best replacement algorithms for Increased hit rates and Energy efficiency respectively.

Abstract: Recently, air quality in residential spaces has been major concern. In particular, the indoor air quality of residential facility
before occupancy, which is related to the interior material, is a serious problem. existing research has mainly focused on pollution control
after construction, but this research has derived I key performance index I about increasing air quality and priority of management with a
controlling schedule. That is the objectives of research. The results show the relative priority of the four major items in wall‐based apartment
buildings and in column‐based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows
more efforts to improve IAQ are needed in material factories and engineering/design companies.
