TL;DR: In this article, the origin and the historic development of energy certification schemes in buildings along with the definition and scope of a building energy certificate and critical aspects of its implementation are discussed.

TL;DR: In this article, a survey of occupant control of the indoor environment in Danish dwellings was carried out by sending out invitations to addresses obtained from a Danish register along with information on dwelling characteristics, and the results of the statistical analyses form a basis for a definition of standard behaviour patterns which can be used to make calculation of energy consumption of buildings more accurate.

TL;DR: In this paper, a combined cooling, heating, and power (CCHP) system operated following the electric load (FEL) and the thermal load (FTL) strategies are evaluated and optimized based on: primary energy consumption (PEC), operation cost, and carbon dioxide emissions (CDE).

TL;DR: In this paper, a parametric analysis was performed in progressive steps, by running the models of a virtual Test Cell and of a sample building, to calculate the associated achievable energy savings, and it was found that thermal inertia effects are enhanced if it is coupled with other energy saving measures and an efficient building use.

TL;DR: In this paper, a simulation software (EnergyPlus and TRNSYS 16) is employed to enable facade design studies considering building materials, window sizes and orientations and the simulation software is used for the investigation of the feasibility of zero energy houses with renewable electricity, solar hot water system and energy efficient heating systems under Cardiff weather conditions.

TL;DR: In this paper, the indoor environmental quality (IEQ) in residential buildings is examined from the prospect of an occupant's acceptance in four aspects: thermal comfort, indoor air quality, noise level and illumination level.

TL;DR: In this article, the effects of vertical greenery systems on the temperature and energy consumption of buildings were simulated and a thermal calculation of the envelope thermal transfer value (ETTV) to obtain their effects on the thermal performance of building envelope is performed.

TL;DR: In this article, an experimental comparative study is described, using cubical test cells with and without PCM composite, concerning the air and wall temperatures, and the results are compared with a numerical modeling and show that hysteresis must be considered to predict correctly the heat transfer.

TL;DR: A stochastic bottom-up model based on domestic occupancy patterns and data on daylight availability is presented and it is concluded that for both individual households and aggregate demand, all relevant features of measured demand are realistically reproduced.

TL;DR: In this article, the effectiveness of night ventilation technique for residential buildings in hot-humid climate of Malaysia is investigated based on a survey on usage patterns of windows and air-conditioners in typical Malaysian residential areas.

TL;DR: In this paper, a full simulation model was developed for absorption cooling systems, combined with a stratified storage tank, steady-state or dynamic collector model and hourly resolved building loads.

TL;DR: In this paper, the authors estimated the effect of shade trees on the summertime electricity use of 460 single-family homes in Sacramento, California, and found that trees planted on the west and south sides of a house reduce electricity use, whereas trees placed on the north side of the house increase electricity use.

TL;DR: In this article, a typical office building in Thailand was analyzed using the life cycle energy analysis (LCEA) method to illustrate the argument that the embodied energy of buildings is a non-negligible fraction of the LCE balance.

TL;DR: In this paper, a detailed model of domestic lighting use is presented, where the operation of individual bulbs is represented within the model and is used to construct high-resolution lighting electricity demand profiles for individual dwellings.

TL;DR: In this article, the authors evaluated the energy performance of double skin facade applied to a typical office building under the climatic condition in Hong Kong and found that a double-skin facade system with single clear glazing as the inner pane and double reflective glazes as the outer pane can provide an annual saving of around 26% in building cooling energy, as compared to a conventional single skin facade with single absorptive glazing.

TL;DR: Exergy analysis of renewable energy-based climatisation systems may be considered an emerging field, where different and often contrasting approaches are followed as mentioned in this paper, where a comprehensive and critical view on the most recent studies on this topic is presented.

TL;DR: In this paper, a transient and implicit model based on computational fluid dynamics is developed to predict the thermal performance and heating capacity of earth-air-pipe heat exchanger systems, which is validated against experimental investigations on an experimental set-up in Ajmer (Western India).

TL;DR: In this paper, the authors evaluate the heat transfer coefficients between the radiant ceiling and room in typical conditions of occupancy of an office or residential building, using experimental tests in an environmental chamber.

TL;DR: In this article, the authors proposed an approach to optimise the exergy flows in buildings and related supply structures, similar to other thermodynamic systems such as power stations, to identify the potential of increasing efficiency in energy utilisation.

TL;DR: In this paper, an insulated concrete wall system was used on exterior walls of a zero-energy house, and its thermal functions were investigated using actual data in comparison to a conventional wood frame system.

TL;DR: In this article, the authors present a study on energy performance of Singapore's hotel buildings and investigate relationships between electricity consumption and number of occupied rooms in individual hotels; the weak correlations found indicate it is necessary to improve energy management when occupancy rate is low.

TL;DR: In this paper, the authors presented a methodology to evaluate the size and cost of PV power system components and the mitigation of CO2 emission, carbon credit and energy payback time.
