Since the effectiveness of the above strategies is related to the thermal mass of the building, the selection of the construction type is crucial. Considering that each type of construction has advantages and disadvantages in terms of energy efficiency, it is difficult to indicate which type of construction is likely to be more effective. Nevertheless, energy efficiency may be achievable when the advantages of both types of construction are exploited.
It is well known that, almost half of the delivered energy is being used by buildings (Bellew, 2000). Energy is consumed in buildings for space and water heating, lighting, ventilation, air conditioning systems and general electrical services (Nicholls, 2002). In order to meet the above description, which is necessary both for survival and adequate levels of comfort it is important to consider the type of construction that consumes energy efficiently. In addition to this, the aim of this paper is to assess the methods used in each type of construction - lightweight or heavyweight- in order to provide efficient energy performance in conjunction with comfort in buildings.
Energy efficient buildings are characterised by maximum utilization of natural means that result in minimised energy demand for heating, ventilation, cooling and lighting (Goulding & Lewis, 1994). According to this, methods such as natural ventilation, passive cooling, day lighting and effective use of external (solar) and internal heat gains are the main natural means that define energy efficient buildings. It is also important mentioning that, energy efficiency is specified by the effective use of natural means on the fabric of the building. As such, natural means present different performance when reacting with different fabrics. Nonetheless, energy efficiency of buildings is achievable when a well-managed combination of
Space and water heating, cooling, ventilation and lighting are the main energy consumers in buildings. Having in mind that buildings have a significant impact towards the environment, the need to assess…
In fact, building plans are closely related to the ethics and values of the environment – social and natural – of the area in which these plans are developed. In the last decades, the above relationship – between buildings and their environment – has become closer; reference is made particularly to the natural environment of buildings – even if their effects can be also expanded on the surrounding community (Dunster et al., 2008).
A major part (nearly one-third) of the total energy production is consumed by the building sector in most of the countries, electricity makes major portion of this total production. The peak demands of electricity in various countries including Japan, US, UK and China are being determined by the consumption of electricity in commercial buildings.
Likewise international market is the part of nation's market that represents the systems of trading securities of entities located outside the nation. Hence international marketing are the marketing activities intended to facilitate the exchange or transfer of goods between nations.
The aim of the paper is to discuss the problems which have emerged in connection with housing and energy efficiency in the light of the current energy issues existing in all states. The technology of housing is changing, and the role of energy efficiency and sustainability in housing is essential for all spheres of human life.
There has been a strong shift of focus on global warming since Al Gore's campaign and documentary came into the public limelight. However, it must be recognized that while much of the hope for reducing global warming comes with the use of alternate energies, what the world should, in fact, be focusing on is a simpler strategy: actually using less energy.
The number is expected to exceed 10 million deaths by 2020, with approximately 70% of these deaths occurring in developing countries (CDC, 2007).
Dietrich et al (2007) performed a cross-sectional study-SAPALDIA (Swiss
This paper will focus on shelters that protect people from explosions, bullets and harmful chemicals. It will discuss the physical properties of such shelters, the mechanics of their protective properties and material types, focusing largely on Kevlar. The paper will also
Since few decades, a huge number of countries have shown their concern regarding the issue of energy conservation that now poses threats and risks to human lives adversely. It is anticipation that the proposed study will be a major contribution to the academic world, and will be very valuable for future researchers in the same field.
es will be researched and then analysis done so as to address the question of why energy efficient housing is becoming more and more important, to offer insight into what triggers residential development within the United Kingdom and eventually emphasize and support the and
Thus as long as the sun shines, the wind will always blow. And as long as the wind blows, people will always harness its power to use in their lives (Burton, 2011, 28).
In ancient times sailors used the wind to explore the world by capturing the wind using sails. Farmers
