The trend to reduce energy losses through enclosures (walls and windows) is an increasingly important part of improving the energy efficiency of a building. Adequate window design and orientation can reduce the heating and cooling requirements of a building.
The need for higher productivity to match the growing competition has forced employers to look for better Indoor Work Environments. Since most of the buildings are being air conditioned, the Heating Ventilating and Air Conditioning (HVAC) systems account for nearly 40% of total building energy consumption. To reduce this energy consumption Thermal energy storage systems (TES) were developed. The Latent heat thermal energy storage (LHTES) systems using water/ice are commonly used for peak shifts in electrical demand.
There are about 16 millions building in Turkey. The total energy consumption of these buildings is approximately 3.48x105 GJ. The energy consumption of the office buildings having HVAC systems can be stated as 150 kWh/m2.year.Turkey is in the warm climate band and the day time outside air temperature in summer (May ~ September) is about 30C. Parallel to the increasing comfort demands, energy consumption also increases. These factors make the necessity for increasing energy efficiency of buildings apparent.
This paper describes the production of the Customer Advising Tool (CAT), a piece of software to help assess the potential for reducing the cooling demand of Office buildings, as required by Article 9 of the EPBD. It is a practical tool aimed at use by building owners, inspectors and auditors as part of the Inspection and Audit process. The tool was developed by the authors as part of the IEE AUDITAC project.
The printers emit the chemical compound when its temperature rises during normal operations. And it primarily influenced the chemical concentrations such as formaldehyde and VOCs (Volatile Organic Compounds) in a living space. The measurements on the various types of prints from different manufacturers such as laser jet type, inkjet type were performed in emission test chambers of 1m3 and 5m3 with ventilation rate of 1.0 ACH(air change rate) supplying low-polluting clean air.
In mid-2002 the Friedberg architects’ bureau Bremmer, Lorenz, Frielinghaus, which had been successful in the architecture competition, was commissioned to plan the new construction of the main branch of the Hagen Sparkasse (savings bank). The Sparkasse ha
In the world of design and engineering, gaps of knowledge between these disciplines are recognized. The learning capacity of the building industry – as well as in other industries – is becoming a main issue, also within Architect-organizations. To link th
A workshop was held in the fall of 2006 for the purpose of developing courses related to “Energy Efficient Integrated Sustainable Design for the Built Environment” for university, college, and vocational schools. The objectives of this workshop were to de
Ventilated façades have become an increasingly employed feature in the design of low energy buildings over recent years in that they offer the attractive features of a conventional glass façade but without the thermal disadvantages. These façades consist
Not long ago the ASHRAE Technical Committee on Load Calculation, TC 4.1, had a “bake off’ of sorts between different peak air-conditioning load calculation schemes and programs. One of the outcomes of this exercise was the realization that practitioners a
