Adoption of daylight as an energy efficiency strategy is especially relevant for a climate like Malaysia, as the country experiences long sunshine hours throughoutthe year. An important aspect of effective daylight strategy is the performance of the window in permitting daylight entry. This paper presents a study conducted to account daylight availability in an office interior undervarious fenestration options; namely window-wall-ratio (WWR), glass types and application of external shading devices of varying depth.

The objective of this work is to demonstrate through a case study of a Shopping Centre in Portugal how daylighting and Passive Solar Strategies can be efficient in this kind of buildings, always characterized by large transparent areas and, in consequence, with enormous heat gains that cause overheating problems, especially in summer. Different strategies will be showed applied to a real case. The Shopping Centre in analysis has considered, since the first phase of the design process, natural ventilation, daylighting and others efficient strategies.

This project presents the performance of air washer chilled water coil system for a yarn industry .The basicprinciples including (1) effectiveness, (2) saturation efficiency and energy consumption for the systems are evaluated.. In addition these spray system prevents the contaminants produced in yarn industries entering into the system. This paper also presents the results of direct evaporative cooling processes, energy efficiency ratio and cooling efficiency for the air washer chilled water coil system.

Microclimate condition in an environment is influenced by the local environment condition. Urban morphology,especially building, pavement and greenery are the main factors. The ambient temperature in a built area located nearby a large park can be reduced with the average of 1.3oC as compared with no park built environment.In other studies also show that area of urban elements (building, greenery and pavement) determines the temperature of a built environment.In the other study, it is found that urban heat island exists in National University of Singapore (NUS).

The objective of this work is to find the optimum window-to-wall area ratio that minimizes the energy cost for cooling, heating and daylighting. Both heating and cooling load are affected by the U-value and the solar heat gain coefficient (SHGC) of the glass whereas the amount of daylighting is affected by the coefficient of visual transmittance of the glass. For this purpose a genetic algorithm is used which is an optimum search technique based on the concepts of natural selection and survival of the fittest.

The solar cooling plant in the Rethymno village Hotel supplies cooling energy to the dinning room as well as it supplies hot water to its central Domestic Hot Water (DHW) network. The solar cooling system is based on an absorption type machine, LiBr/H2O, able to be generated at the level of 80oC, since it is of single effect. The favorable environmental impact of the installation is highly important since the oil displacement by the solar energy yields to high CO2 emissions reduction.

The heating system of the bioclimatic building of CRES comprises the entire heating plant including a solar assistedheat pump, the Solar Air Collectors (SAC) as well as the heat distribution system (comprising a fan coil unit network).

This paper looked into the possibilities of adaptive reusethrough the environmental retrofit of an existing warehouse. The project was built on the intent of convertingan abandoned building into an exhibition hall, within the tropical island climate of Subic Bay, Philippines.Analyses of the existing warehouse were undertaken;from this initial study, three main strategies were identified shading, the use of thermal mass, and ventilation.These three aspects formed the core of the research,and were further investigated through the use of computer simulations.

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.
