This work presents the results of the thermal and environmental performance of a new residential building, as a function of the heating system used, designed to Viseu, a moderate climate zone in Portugal. A case study has been conducted on a conventional residential building, modeled according to Portuguese Thermal Building Regulation (that is complying with EN ISO 13790 and EN 15603) and Life ...

At present, China is going through a rapid rate of mass urbanisation, and this poses a number of challenges for the building sector. On one hand, under new directives from the government, new buildings will have stricter energy requirements and existing buildings will also need to lower their rate of energy consumption, on another hand, the lifetime of buildings are now intended to last longer,...

More than 44% of building energy consumption in the USA is used for space heating and cooling, and this accounts for 20% of national CO2emissions. This prompts the need to identify among the 130 million households in the USA those with the greatest energy-saving potential and the associated costs of the path to reach that goal. Whereas current solutions address this problem by analysing each bu...

the purpose of this research is to found the impact of built area and occupant number on winter gas consumption in the residential building sector of iran, shiraz.sothe annually and monthly gas consumption data through 19 houses were analyzed to achieve the heating energy consumption and operation month.the average operation months of gas heating consumption were from first of november up to en...

A refurbishment project at the University of Northumbria in Newcastle upon Tyne, United Kingdom, provided the opportunity to install one of the largest building-integrated photovoltaic systems in Northern Europe. Photovoltaic panels have been incorporated into w Integrated into conventional rain-screen overcladding w Installed using normal building industry practices w High system reliability H...

Existing building energy simulation tools have a purported tendency to over-predict heating use and, in some cases, to under-predict cooling use, an outcome often attributed to inappropriate assumptions about thermostat management. As a result, a systematic review was conducted for the purposes of determining typical heating and cooling set points for single-family houses in North America. The ...

The ability to sense and predict occupancy – i.e. to establish when the residents are and will be in a building – represents a basic requirement for the energy-efficient operation of many building automation systems. In residential households, in particular, the absence of all residents allows a heating controller to automatically lower the temperature of the home, thereby saving energy that wo...

The use of solar collectors with coloured absorbers for water heating is an area of particular interest when considering their integration with buildings. By matching the absorber colour with that of the roof or façade of the building, it is possible to achieve an architecturally and visually pleasing result. Despite the potential for the use of coloured absorbers very little work has been unde...

Significant progress has been made on maximising passive solar heat gains to building spaces in winter. Control of the space heating in these applications is complicated due to the lagging influence of the useful solar heat gain coupled with the wide range of construction materials and heating system choices. Additionally, and in common with most building control applications, there is a need t...
