“…A basic assumption was done on the internal heat gains (including the solar thermal gains) of the building and account approximately 50 % of the envelope of the building (Suehrcke et al 2008;Yacouby et al 2011;Lam and Li 1999). Therefore the losses, in total, Q tot , are given from:…”

In this paper cold and thermal storage options via wind energy surplus are examined aiming to enable higher wind integration. A case study in Greece with an installed wind farm (WF) was investigated reviewing the possibilities for higher renewables integration using thermostatically controlled loads (TCLs), analysing thermal and cold storage possibilities according to the needs of the local municipalities. The basic aim is to describe the idea of an aggregated system with a number of residential freezers, in order the wind power to be stored in the residential cold stores aiming at maximizing the benefit to the grid, utility or cold store owner avoiding at the same time wind curtailment. In addition, for thermal storage, by calculating thermal losses of the building, ventilation losses and adding up internal thermal gains of the building the space heating needs can be calculated.

In this paper wind energy to thermal and cold storage scenarios were examined to enable high wind integration through converting renewable electricity excess into thermal or cooling energy, saving part of the energy used in an area and eliminating the need to possibly build a new coal fired plant. Case studies in Crete Island (not interconnected to the power grid of Greek mainland) with onshore wind power installed were investigated. The aim of this work was to review the options for greater integration of renewables into the grid and the main idea was to analyze the wind to thermal and to cold storage according to the needs of two small municipalities.

“…This technique is widely recognized and clearly observed in the hot regions, but its application is poor in the tropics. Based on a study in Malaysia conducted by Yacouby, Khamidi, Nuruddin, Farhan and Razali (2011), the results indicated that the majority roof tiles colours are dark as Red 38%, Brown 25.9%, White 9.5%, Beige and Blue 7.8% Black 4.9% and Grey 2.9%. In Malaysia, Allen et al (2008) showed that concrete roof tiles are the most commonly used roofing materials, as it represents 85% followed by clay tiles and metal deck with 10% and 5% respectively.…”

Pitched roof design represents the common system for the most tropical houses in Malaysia. Different angles and colours of this roof deliver various impacts on the indoor environment. This study focuses on estimating the amount of heat gain and roof surface temperature obtained from different roofing aspects. The paper hypothesizes that colour technique could change pitched roof design more than roof angles and materials. The research was based on simulation analysis applied on an actual room size with different roof angles (0°, 30°, 45° and 60°) in the Malaysian environment. As a result, the findings of different roofing systems affirm the hypothesis and show the significant of roof colour compare to area, angles and materials. This study contributes efficiently to the knowledge of the roofing design in the tropics. In addition, it will shed light on the economic sector and sustainability for optimum roofing concept particularly for low cost housing components in Malaysia.
