Illuminance Level

In recent years, Malaysia has experienced climate change that leads to the higher consumption of energy dueto the increasing outdoor temperature that affects indoor discomfort conditions. Paints were found to be the insulationmaterial that is increasingly important because of their benefits in terms of thermal comfort and energy savings. Therefore,the aim of this study is to determine the effect of different types of paint to the residential building. Two types of paints wereapplied on indoor walls of identical room and their performance was compared. The equipment used to measure theperformance includes data logger and thermocouple for temperature performance and lux meter for illuminationperformance. The experiments consider the impacts of paints on interior surface temperature, wall orientation, indoor airtemperature and the illuminance level. The result shows that the air temperature of the room was brought down considerablyat about 1.9°C by implementing the reflecting paint on the indoor walls. The most significant effect is on the surfacetemperature with the highest temperature reduction of about 2.8°C which occurs at west wall after the application ofreflective paint that makes it as the best location to use reflective paint. For illumination, the results show that reflective paintgives significant effect compare to energy saving paint with the highest illuminance level of 392 lux. With the application ofreflective paint, the indoor temperature is improved and thus minimized the energy usage. Reflective paint has also presentedthe ability to reduce the indoor temperature, the effective wall orientation when applying it and improves the illuminancelevel of indoor building.

Linear Manner

This work addresses the effect of using thermochromic paints in residential buildings. Two different thermochromic paint types were considered: One that changes properties through a step transition at a certain temperature, and another that changes properties in a gradual/linear manner throughout a temperature range. The studied building was a two-floor villa, virtually simulated through a digital model with and without thermal insulation, and considering thermochromic paints applied both on external walls and on the roof. The performance assessment was done through the energy use for heating and cooling (in conditioned mode), as well as in terms of the indoor temperature (in free-floating mode). Three different cities/climates were considered: Porto, Madrid, and Abu Dhabi. Results showed that energy savings up to 50.6% could be reached if the building is operated in conditioned mode. Conversely, when operated in free-floating mode, optimally selected thermochromic paints enable reductions up to 11.0 °C, during summertime, and an increase up to 2.7 °C, during wintertime. These results point out the great benefits of using optimally selected thermochromic paints for obtaining thermal comfort, and also the need to further develop stable and cost-effective thermochromic pigments for outdoor applications, as well as to test physical models in a real environment.

Parametric Studies

This work addresses the effect of the total solar reflectance (TSR) value of paints applied in residential buildings upon their thermal performance. A semi-detached residential building was modeled in the ESP-r software, and taken as the basis for parametric studies which assessed the effects of variations in (i) the TSR values; (ii) the thermal characteristics of the building envelope; (iii) the location/climate; and: (iv) the way how the indoor temperature is controlled. The parametric studies were used to find optimal TSR values for each combination of Location + Building envelope characteristics (mainly the existence of thermal insulation). It was concluded that paints having a carefully chosen TSR value lead to better indoor thermal temperatures if the buildings have no mechanical heating or cooling, or to energy savings of up to 32% if they do.

Clothing has a direct influence on the thermal comfort of an occupant and so, indirectly on the energy use of a building. Literary sources point out a lack of data about clothing behaviour in residential buildings. In order to assess the clothing behaviour two kinds of surveys are created: logbook surveys and online questionnaires. Both surveys are executed between March 11 and April 5, 2019. The mean clothing insulation worn during the investigation period is 0.58 clo. This clo-value differs from the clothing insulation values provided by Fanger, which are 1.0 clo for winter months and 0.5 clo for summer months. The influence of the indoor temperature, outdoor temperature, weather history memory, gender and age on the clothing behaviour is analysed. All variables have a small significant influence on the clo-value. It was found that occupants tend to wear the same clothes when they are at home. So, each participant clothes him/herself to be comfortable in their clothes and in the temperature of their own room. People who are used to live in lower indoor temperatures will, and are used to, wear more clothing insulation to be thermally comfortable than people living in warmer indoor temperatures. An adjustment in clothing behaviour can make a big impact on the energy use of residential buildings. A decrease in indoor temperature of 1°C can lead to heating energy savings of 10%. To remain thermally comfortable, the occupant must only wear an extra insulation value of 0.17 clo, which corresponds with a shirt. The question remains if occupants will effectively use the opportunity of changing clothes to lower their energy use.

The consumption of electrical and thermal energies by appliances in the residential building sector is growing fast and lots of methods are being followed to beat the energy demand in this sector. Among the various approaches, performance enhancement of refrigeration systems has been recognized as one of the important areas for investigation. Due to the increase in the use of small-scale applications and their effect on global energy requirements, specific research has to be focused on small-scale systems with water-cooled condensers to reduce energy usage in residential buildings. In this study, the evaporative condenser of a refrigeration system was connected to the prevailing water distribution with a submerged motor. The proposed system was analysed for energy savings, performance enhancement, and environmental benefits.

Since buildings are one of the major contributors to global warming, efforts should be intensified to make them more energy-efficient, particularly existing buildings. This research intends to analyze the energy savings from a suggested retrofitting program using energy simulation for typical existing residential buildings. For the assessment of the energy retrofitting program using computer simulation, the most commonly utilized residential building types were selected. The energy consumption of those selected residential buildings was assessed, and a baseline for evaluating energy retrofitting was established. Three levels of retrofitting programs were implemented. These levels were ordered by cost, with the first level being the least costly and the third level is the most expensive. The simulation models were created for two different types of buildings in three different climatic zones in Palestine. The findings suggest that water heating, space heating, space cooling, and electric lighting are the highest energy consumers in ordinary houses. Level one measures resulted in a 19–24 percent decrease in energy consumption due to reduced heating and cooling loads. The use of a combination of levels one and two resulted in a decrease of energy consumption for heating, cooling, and lighting by 50–57%. The use of the three levels resulted in a decrease of 71–80% in total energy usage for heating, cooling, lighting, water heating, and air conditioning.
