Thermal comfort

About 60% of the building optimization studies used the single objective approach, e.g. only one objective function is optimized at each optimization run (energy demand or operational cost, or thermal comfort and so on). The single most common objective was energy use, used in 60% of cases, followed by cost objectives (construction, operational, life-cycle, total). Energy and cost objective functions were present together in nearly the same amount…

to 30C throughout the year. (Weather Zone, 2014) During these extremes in the weather thermal comfort is the condition of mind to which the body finds the temperature satisfactory, should be achieved. The temperature of a household can be changed through the uses of air-conditioning, heaters and fans which can cause energy prices to skyrocket. Through the use of insulation households can achieve thermal comfort with little or no use of electronic heating/cooling. Insulation can help the people…

pressures. In the process, fresh air is introduced and ventilated air is removed from an occupied space. The primary aim is to preserve the qualities of air. (Amit Gupta, 2006). It may also be used to lower the temperature inside an occupied area for thermal comfort. Basic Concept of Natural Ventilation Source: Google According to Eugenijakin et al. (2009), in Indoor Air Quality (IAQ), natural ventilation helps to eliminate odour, dust, excess humidity, smoke, heat and airborne bacteria. For…

BTEC Subsidiary Diploma in Construction & the Built Environment Unit 4 – Construction Science and Materials Assignment 1 Human Comfort within Buildings Report Student: Peter McCaughey Teacher: Mrs Keyes Scenario A property developer is converting an old railway station into retail and office accommodation.

desire to keep drones away from their property. AUDS was originally developed by three leading technological companies in the UK, as it requires multiple complex radar, directional inhibitors, and thermal camera systems for it to detect…

buildings in Europe are DSF based buildings. In the 20th century, the technologies are growing rapidly and because of computers and other technical equipment in the offices, the internal heat gain has increased. In this case, it is important to preserve comfort and reduce cooling costs (Elisabeth Gratia, Andrè De Herde, 2007). That is where DSF comes in and plays an important role not only aesthetically, but also decreases the risk of overheating indoors and provides…

2. Content 2.1 Different types of Passive house Construction The images below show some of the various different wall constructions that are often used to build a Passive house. Figure 2.1: different types of wall construction used to build passive houses which should give the desired U-value of 0.15W/m2K or less Some of these options would be more structurally sound compared to others. Some of the above options may be used that can often make a passive build cheaper than a conventional…

Although attic-discontinuous roof structure is relatively effective in weather controlling, thermal mass with external insulation is more efficient in avoiding heat loss during winter and preventing excessive heating during summer. After several trials, adding both roof and ceiling insulation to R4.0 is the way to achieve the best energy performance…
