The development of ventilation strategies for moisture problems, reduction of the heating and cooling demands, the guarantee of hygrothermal and hygienic comfort in building constructions as well as the performance and durability of building components are questions which are related to the strong interactions between climate conditions, building use and the building envelope. These questions can be answered with the help of efficient building simulation tools before building construction or retrofit.

Non-intrusive load monitoring (NILM) is a method to estimate the energy and power use of individual electrical devices in buildings. It generally relies on aggregate power metering (at the whole-building or branch circuit level) and special signal processing techniques to disaggregate the total power consumption data into loads from individual appliances, thus avoiding the time and expense of placing power meters on each device. Over the last 30 years, a variety of NILM techniques have been developed, which differ in the types of data collected, the sampling frequency, the types of metering hardware required, and the signal processing algorithms employed.

The Copenhagen Accord (2009) recognizes that 'the increase in global temperature should be below 2 degrees Celsius' (compared to pre-industrial levels, '2° target'). In recent years, energy economics have derived welfare-optimal investment streams into low-emission energy mixes and associated costs. According to our analyses, auxiliary targets that are in line with the 2° target could be achieved at relatively low costs if energy investments were triggered rather swiftly.

The available pool of IPv4 addresses - less than 7% - will run out soon. The solution is IPv6. While this seemingly endless number of addresses will help support next-generation, IP-based networks and services, many companies have been slow to adopt IPv6 because of cost, and the need for bridging technology to make IPv4 and IPv6 systems compatible.
