Direct Ground Cooling: Influence of Ground Properties on the Ground Heat Exchanger Size | 2006 | English
The purpose of this paper is to introduce Energy Smart Tool, a new web-based building energyperformance benchmarking system developed recently by Energy Sustainability Unit of NationalUniversity of Singapore.
In this paper, a model for predicting whole building heat and moisture transfer was presented. Both heat and moisture transfer in the building envelope and indoor air were simultaneously considered; their interactions were modeled.
The state of the Implementation of the European Energy Performance of Buildings Directive (EPBD) in Austria | 2006 | English
The process of implementation of the EPBD in Austria is now carried out for several years.
Study on Performance Evaluation of Mechanical Ventilation Systems for Occupied Houses | 2006 | English
In the first phase of the current project, the ventilation rates of occupied houses in the northern region of Japan were investigated from 2001 to 2005.
Detailed mathematical models of VAV equipment and subsystems have been developed and used tocompose larger DCV systems with a large degree of detail.
Sustainable architecture design for tropical climates requires the use of natural ventilation besideseveral strategies, as appropriated materials, site location, faade orientation, solar shading, etc.
Sustainable Energy Management Based on the European Energy Performance Building Directive (EPBD) | 2006 | English
The EPBD prescribes an energy performance certificate for buildings.
This study aims at investigating the actual conditions of indoor environment in schools in order toobtain fundamental information for proper ventilation design of buildings.
The absolute necessity of air renewal to maintain indoor air quality and thermal comfort in buildingsfaces the major issue of energy consumption reduction and optimisation in building sector.
Natural ventilation driven by the combined forces of wind and buoyancy has been studiedexperimentally for a building flanked by others forming urban canyons.
Important oversizing factors are observed for room air-conditioners leading to important energy wastes and costly summer peak demands for utilities.
Results of Monitoring a Naturally Ventilated and Passively Cooled Office Building in Frankfurt A.M., Germany | 2006 | English
In this article the concept of a new energy-efficient office building and results of a 3-year monitoringare described.
Analytic models and static approaches as the case of Fanger, Deval, Sherman, Gagge, and Stolwijkmodels cannot completely predict indoor thermal comfort.
Ventilation is essential for health and comfort of building occupants. It is particularly required to diluteand/or remove pollutants emitted by occupants metabolism.
Prediction and Control of Temperature in Air-Conditioned Indoor Spaces Using Proper Orthogonal Decomposition | 2006 | English
A method for controlling the temperature of the occupancy zone in a room equipped with a fan coil ispresented. The heterogeneity of the air velocity field and the temperature distribution is considered.
This work lies within the concept of positive energy buildings.
Impact of Pump Control on Indoor Climate and Energy Efficiency of Hydronic Networks | 2006 | English
The use of variable speed pump allows to save energy. Therefore, the impact of these technologieson the heating system and thermal comfort in buildings is rarely highlighted.
The use of electricity in buildings constitutes around 16% of Singapore’s energy demand. To incorporate energy efficiency measures is one of the key mission to ensure that the economy is sustainable.
Measuring Air Change Rates using the PFT Technique in Residential Buildings in Northern Portugal | 2006 | English
Portugal has technical recommendations and standards regarding ventilation rates in naturalventilation systems.
