A STUDY OF FAÇADE THERMAL PERFORMANCE FOR NON-AIR CONDITIONED RESIDENTIAL BUILDING
… by TAS simulations, the impact of solid wall U-value on fagade surface temperature, indoor mean radiation and indoor thermal comfort was studied. It is found that although the U-value of the wall can affect the wall internal surface temperature, it is not the only dominated factor affecting the …

An Analysis of the Impact of Reinforcement on Response Variability on Multiple Behavioural Dimensions
… of each dimension, as measured by the U-value, was higher for the VAR group than for the YOKE group. In Experiment 2, three groups of adult participants received reinforcement when they varied on two of the three dimensions of the rectangles drawn. Results showed that reinforcing …

Passive solar energy : modifications of existing masonry walls to improve thermal performance.
Existing brick walls usually have a high U value, one method of improvement is by insulation, but if the wall faces approximately south, it is possible that greater benefits could be obtained by improving the wall's performance as a solar collector. Three solid 225 mm walls were constructed: one …

Evaluation of the potential impact of electrochromic windows on the energy performance of commercial buildings
… performance (solar and visible transmittance, U-value, and solar heat gain coefficient). A critical evaluation of existing control strategies is performed using DOE-2.1E to study the effect of several driving variables for switching on the cooling load of an existing large commercial building. …

An alternative optimization model and robust experimental design for the Assignment Scheduling Capability for the Unmanned Aerial Vehicles (ASC-U) simulation
… in this thesis can successfully maximize ASC-U value without the use of a heuristic; smaller optimization intervals do not guarantee higher total value when the heuristics are included; to maximize total value, Early Return should be set to FALSE and Secondary Areas should be set to TRUE; an …

Biologically inspired transparent material as an energy system
… levels set by a singleprescriptive static, the U value. This is energetically weak, a dynamic IR absorberstrategy is needed, since performance requires change by the hour, season, andweather conditions to sync with a warming earth atmosphere. A transparent dynamicIR absorber , will be modulated by …

Investigation of solid polymeric hollow fiber heat exchange devices for use in thermally-driven desalination processes
… transfer coefficient based on the inside area) values attained in the hot brine-cold water system for PEEK and PP-based modules were 1914 W/m^2-K and 2076 W/m^2-K respectively. The maximum U value attained in the two-phase heat exchange system was 1700 W/m^2-K. Overall, the PP-based module HEPP2 …

Heat conduction in two and three dimensions : computer modelling of building physics applications
… radiation in cavities, how to obtain a proper U-value for a foundation with floor heating, etc. The robust method of explicit finite differences is used. This method closely follows the physical equations. The mathematical equations for two- and three-dimensional heat conduction and the numerical …

The role of aesthetics in energy-retrofit strategies: the case of solid wall houses in the UK
… potential energy savings arising from the U-values ofwalls in solid wall properties has led to under- or over-estimation of SWIperformance. The second gap is the need for innovative solutions to unlockthe demand for slow progressed SWI in the UK. In home improvement, theaesthetic factor is …
