Das Thema soll in einen Grenzbereich der Materialwirtschaft führen, der durch die tagespolitischen Ereignisse immer größere Bedeutung für die Unternehmung gewinnt. Naturgemäß ist in einer marktorientierten Gesellschaft das verkaufs­ fähige Produkt da~ Objekt aller Anstrengungen und Leistungen. Produktion und Verkauf stehen im Blickpunkt, andere Bereiche werden als notwendig be­ trachtet, während das Gebiet der Entsorgung innerhalb der Unternehmung zu­ nächst ohne besondere Beachtung bleibt.

But predicting the net GHG emissions due to this light bulb switch is not straightforward for all Canadian provinces. In the province of Ontario, electricity generation is provided by a variety of sources, some of which generate GHGs, such as coal and natural gas, and some of which do not, such as hydro or nuclear. In this case the situation is much more complex and the impact of a switch from ILBs to CFLBs on GHG emissions depends on what electricity generation sources are turned off, or throttled down, with the energy savings that are achieved.

T1 = Type 1 epithelial cell, MØ = macrophage, E = endothelial cell, PM = particulate matter (Figure from (Kocbach 2008)) Ambient particles comprise a large variety of different components, such as allergens, metals, organic compounds and microbial components. This review will focus on two groups of components commonly associated with PM, polycyclic aromatic hydrocarbons (PAH) and metals. An important question is whether particles from different sources or different components of particles trigger the release of the same signalling molecules, or whether qualitative and quantitative response differences exist.

Thus, by again defining the building envelope as the system boundary, a crude estimate of the annual energy (in kWh) required to cool a household during warm days (C) involves adding the annual heat energy gains by interior lighting (CL) with annual air conditioning energy requirements (CAC), such that: = (7) + The annual energy requirements of an air conditioner are dependent on cooling degreedays, outdoor design temperatures, and energy efficiency ratings. Natural Resources Canada (2004b) uses the following formula to estimate space cooling energy requirements (in kWh): = ( ¡ ¢ ) ¢ (8) where Q = basic air conditioning cooling capacity (Btu/h); CDD = cooling degree-days (K·day); Td = air conditioning design temperature (°C); and EER = air conditioning energy efficiency rating.
