Ecology in Architecture Design (EAD) is a project with the main aim of developing a blended (face to face lecturesplus online activities) learning course about how to integrate ecology in the architectural design, both at the level of a single building and of territory. EAD started in July 2004 as a project founded by the Swiss University Conference within the Swiss Virtual Campus(SVC), the national program studying the introductionof information and communication technologies in universities and universities of applied sciences.

Every time with major frequency grows the necessity of energy efficient buildings, adapted to their environment, which consume and contaminate as least as possible.In this study it has been analyzed and evaluated the thermal conditioning of two blocks of flats, a renovation one and a new one, taking advantage of the bioclimatic technologies and using renewable sources of energy.

The building sector is at present responsible for more than 40 % of the EU energy consumption. There are technologies under development, which could substantiallyimprove (up to 30 %) the energy performance of buildings, reducing the conventional energy demand in new and existing buildings and substantially contributingto reduce energy intensity, through combined measures of rational use of energy and integrationof renewable energy technologies.

When an energy balance is calculated in accordance with DIN V 18599, an integrative approach is taken, i.e. the building carcass and the utilization of the buildings technical installationsand equipment are evaluated together,taking the interaction of these factors into consideration.In order to provide a clearer structure, the DIN V 18599 series of preliminarystandards is divided into several parts, each having a particular focus. The DIN V 18599 series of preliminary standards providesa method of calculating the overall energy balance of buildings.

This research aims at developing new standardized typologiesof semitransparent double skin facades formed by an external semitransparent PV laminate, a wide air gap and a rear glass (Figure 1). There are actually many buildings in Europe which incorporate such activefacades, but all them have been designed as user defined projects and very few of them accurately evaluatethe feasibility of using the heat produced by the air channel.

This study compares various optimization criteria for a solar domestic hot water system (SDHWS). First of all, we present the various parameters used to evaluate a SDHWS. We consider the energetic, exergetic, environmentaland financial analysis. Various optimization criteria of a standard solar hot water system are then proposed. The optimized solutions are compared with a standard hot water system.

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.
