In this paper, a purposely designed code for the performance analysis of the Water Loop Heat Pump (WLHP) systems is presented. Hourly, daily and seasonal energy system consumptions, operating economic costs and environmental impact assessments are dealt with. For the scope of comparison, the...

Conducting energy-efficient designs on building window can be a solution to relieving the pressure caused by growing building energy consumption. In this paper, a series of simulation studies were carried out to evaluate the performance of several popular energy-efficient window designs in...

The more the design of buildings becomes bioclimatically conscious, the more the behaviour of these buildings tends to become skin dominated. Double elements, much like the different layers of the skin of animals or human beings, can serve more than one purpose at the same time, such as shading,...

Energy efficiency potentials slumbering in the envelopes of existing and newly constructed buildings are significant and still largely untapped. Increasing concerns of policy-makers about non-sustainable energy use and its implications especially on climate change currently spur a growing...

While space conditioning load contributes largely in grid critical peak, shifting a part or full to the off-peak period could have significant economic effects on both energy supply and demand sides. This shifting technique is accomplished by storing energy during off-peak periods to be utilized...

Among solar passive systems integrated in buildings, sunspaces or solar greenhouses represent a very interesting solution. A sunspace is a closed, southbound volume, constituted by transparent surfaces, adjacent to a building, which reduces winter energy demand thanks to the use of solar gains....

The thermal performance of building envelopes is the determinant factor of building energy consumption, and especially envelope retrofitting is an effective way of reducing energy consumptions in existing building. For different climates, there may exist different optimal retrofitting schemes....

This paper provides a review of the energy saving policies and technologies on double glazing windows, central heating and air conditioning in office buildings. After which results of a face to face survey of 685 companies’ managers are presented, which give insights into the facts that have...

A significant portion of the total primary energy is consumed by today's buildings in developed countries. In many of these buildings, the energy consumption can be significantly reduced by adopting energy efficiency strategies. Due to environmental concerns and the high cost of energy in recent...

Due to its high thermal performance, ground source heat pump systems (GSHPs) have been introduced as an alternative to reduce energy consumption of heating and cooling systems. The thermal performance of GSHPs strongly depends on ground temperature and energy demand for heating and cooling...
