The ice rink floor is the largest heat exchanger in an ice rink. The important part of the floor consists of concrete, and the thermophysical properties of this concrete have strong influence on the energy usage of the ice rink. The thermal conductivity of concrete can be increased by using iron ore as ballast. In this study, the Transient Plane Source (TPS) method showed an increase up to 58.2...

from 60 decade  sustainability issues  and sustainable developing  have opened a way in scientific meetings associated with  environment and urbanization and architecture. sustainability goals are improving of environment situation , less pollution  and at least interference on  land and interaction of  natural and artificial environment , that most of these cases attracted attention in archite...

Fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in Kenya. The heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in Kenya. As part of innovation efforts, several energy-conserving technologies have been developed. A unique cook stove named M...

The exponential growth in users of computer over the years has impacted environment drastically. A primary concern of this paper is to study the transformation of computer state from grey to green. Green IT is basically referred to Green computing . this study shows how the emerging green technology reduces the negative impact of computing on the environment. The goal of green computing is simp...

Energy wasted in buildings is a major fraction of total energy wasted in today’s cities. Most people are not aware of inefficiencies and energy wasted in their homes. Making people aware about energy wasted in their homes and inefficiencies in their energy consumption behaviors could contribute to large energy savings at the city scale. Many energy-saving programs, run by the governments, non-p...

Energy is a very important resource for the development of residential and industrial sectors, it should be used with high efficiency, low environmental impact, at lowest possible cost [...]

Buildings are among the largest consumers of energy. Part of the energy is wasted due to the habits of users and equipment conditions. A solution to this problem is efficient energy usage. To this end, an energy audit can be conducted to assess the energy efficiency. This study aims to analyze the energy usage of a primary school and identify the potential energy reductions and cost savings. A ...

Energy resources saving policy in municipal housing economy (MHE) is a priority in the national economy of Russia. It is aimed at reduction of costs for housing stock maintenance and operation and for optimization of housing and municipal services payment system. Suggested in the article is the organizational and economical mechanism of energy resources saving management in MHE, including funct...
