This study presents some results from a monitoring project with night ventilation and earthto- air heat exchanger. Both techniques refer to air-based low-energy cooling. As these technologies are limited to specific boundary conditions (e.g. moderate summer climate, low temperatures during night, or low ground temperatures, respectively), water-based low energy cooling may be preferred in many projects. A comparison of the night-ventilated building with a ground-cooled building shows major differences in both concepts.

Recently, the role of the architecture which is corresponding to climate change and saving energy has been important. This study drew factors about design principle, technology performance on passive house, focusing on apartment and multi-family house cases in Europe. The dwelling type of Korea and climate, however, are different from the European styles, and therefore it is necessary to develop energy efficient design, technology and details that is applicable to Korea's apartment.

The issue of evaluating possible strategies for improving the building stock's energy and environmental performance is crucial. This applies to all buildings including residential and non-residential. In particular, hotels represent a group of both economic importance and public interest. Within the frame of a field study, and in a bottom-up approach, data related to the energy and environmental performance of Hellenic hotels were gathered, along with information related to occupancy levels, indoor environmental quality matters and management procedures.

The reduction of carbon dioxide emission due to energy consumption in the household sector is an urgent task, worldwide. As a measure to respond to the task, a new regulation has just been enforced since April 2009, in Japan. This regulation evaluates the energy performance of detached houses by estimating the primary energy consumption for different uses, namely, heating, cooling, ventilation, domestic hot water and lighting.
The European Commission has mandated CEN to produce a set of standards to support MemberStates for the national implementation of the EPBD. This paper focuses on one of these standards,EN ISO 13790, "Energy performance of buildings - Calculation of energy use for space heating andcooling". It describes the history of this standard which started with a simplified calculation of the energyuse for heating of residential buildings only.
The International Organization for standardization (ISO), Technical Committee 163 "ThermalPerformance and Energy Use in the Built Environment" (ISO/TC 163) has produced and will producesets of standards by reference to which performance requirements can be expressed at various levels,from materials to complete buildings. A coherent set of new work items concerning the energyperformance of buildings has been launched in April 2007 which are briefly presented in this paper.
The International Organization for standardization (ISO), Technical Committee 163 "ThermalPerformance and Energy Use in the Built Environment" (ISO/TC 163) is dealing with development oftools that can be used to design and construct or retrofit energy efficient buildings and installations. Theoverall aim for this is to reduce our dependency of non-renewable resources and to reduce theemission of harmful substances to the air. Methods are needed for the evaluation of the energyperformance of complete buildings and parts of buildings or building installations.
Methods are needed for the evaluation of the energy performance of complete buildings and parts ofbuildings or building installations. In order to arrive at energy efficient buildings, materials and productsthat effectively contribute to the thermal performance of the building and its installations must be used.For that standards dealing with the design and evaluation of materials, components and systems playan important role.
The application of system identification techniques to the energy performance assessment of buildings and building components requires a high level of knowledgeof physical and mathematical processes. This factor,combined with the quality of the data, the descriptionof the monitoring procedure and test environment, together with the experience of the user of the analysis software itself, can produce varying results from differentusers when applying different models and software packages.
Nowadays energy performance is an increasing concern to sustainable urban planning because of itsimplications in energy consumption patterns. Interactions between urban form and urban microclimatehas been broadly studied from large scale such as the city as a whole through heat island studies.However urban planning needs to be addressed at local scale as well.The purpose of the work is to study experimentally thermal conditions on outdoor spaces within theurban fabric at neighbourhood scale in Santiago city, Chile.
