In November 2006 a “CO2 emission and energy saving potential through correct pipe insulation of space heating and domestic hot water distribution systems in the new and existing buildings.” paper [3], sponsored by Armacell - worldwide producer of flexible

The Project of Ponte da Pedra came out of an Ideas Competition, which is, by the beginning, a good indicatorof the high quality of the housing architecture of Ponte da Pedra.

In order to simplify the procedure for evaluating winter building energy performances, most of existing standard and rules make reference to the building energy balance under steady state conditions.

The aim of the specific paper is the analysis of the efficiencyof power lines as a communication media for Building Energy Management Systems. The reason behindthis scope is the ability of power lines to be installedin existing buildings without extra wiring.Building Energy Management Systems (BEMS) constitutea part of automation systems. BEMS implement control the indoor environmental parameters while minimizingenergy consumption.

Building AdVent is a new collaborative project funded by the EU through its Intelligent Energy – Europe (IEE) programme. The aim is to help spread good practice in ventilation design through a series of case studies and supportive teaching materials. This

The climate in southern Brazil is characterised by mild winters and hot-humid summers which requires the design to be adaptable to the often conflicting summer and winter requirements. In the residential sector, air conditioning consumption is still low, but it has been growing significantly along with an increase in peoples purchasing power, which emphasizes the importance of encouraging a change in construction practices (MME, 2001).

Library buildings offer special conditions to favor the adoption of low energy strategies. In addition, their potentialhigh degree of interaction with the youth and a specific educational role makes of libraries one of the best typologies of public buildings to spread good practiceson how to manage energy, indoor environment and sustainability. This study focuses on the energy efficiencyof libraries in the West and Tejo Valley Region, Portugal, in the context of the elaboration of its new regionalplan (PROT) [1].

One of the current challenges in the urban climate researcharea mentions the standardization of procedures for data collection and analysis (OKE, 2005); this involvesnomenclatures and methods, so that the transmissionof the developed technology can be better understoodand applied in diverse realities.

This paper looks at the design and construction in 2006/2007 of a ‘green’ office building in Wellington, New Zealand. Wellington lies at 42 degrees South of the equator, in a region known as the ‘Roaring Forties’ due to the constant winds, making it an ideal situation for wind farms. While the temperature range in the city is moderate, the strong wind has severe climatic effects.

This paper describes ongoing energy benchmarks studies of double-skin façade buildings. A comparison between energy performance of these actual buildings and European office buildings benchmarks is discussed. Some preliminary results are presented.
