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
Regulatory devices for the energy efficiency of buildings currently in use, including the new EU “Directive on the Energy Performance of Buildings” [1] and especially the methods currently proposed in the various member states to determine and judge the e
Already 20 years ago, Gro Harlem Brundlandt stated «I believe the time has come for higher expectations, […] for an increased political will to address our common future» ([1], p. 13). Indeed reading the newspapers one could get the notion that finally po
To accurately estimate the natural wind driven ventilation potential of a specific low rise building in a densely shielded or built-up area under local wind conditions, it is necessary to have site wind frequency data, pressure coefficient data, details about the windward and leeward openings of the building and the data related to building design. This paper summarises the appropriate data and discusses how to obtain these in order to estimate the natural cross ventilation potential of such a low-rise building.
Recently in Korea, plywood has been widely used as a floor material for Korean floor heatingsystems (Ondol) instead of the conventional oiled floor paper. Volatile organic compounds(hereafter VOCs) are easily emitted from the plywood and adhesives that constitute the floorinto the indoor environment due to the warm temperature of the floor. In this study, emissioncharacteristics of VOCs from adhesive and paints within an Ondol floor are assessed using theSmall Chamber Method in residences with plywood floors.
