CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Using a simulation application and a sample of five existing office buildings, we parametrically explored building features and measures that could improve the thermal performance of office buildings in Kumasi, Ghana.

To improve the reliability of the simulation results, the simulation. Abstract: Computer simulation is becoming popular in assessing thermal performance in building. It can predict the energy consumption and also the comfort of the building.

Office building occupants typically spend a minimum of 8 h daily in indoor spaces for work purposes. Consequent of such sustained long-hour residence, the suitability of ambient thermal and visual conditions are vastly important, both for long-term workplace safety and the physical comfort of occupants [, ].Cited by: 1.

To meet to such a problem, retrofitting strategy can be adopted for reducing energy loss in existing buildings through appropriate materials. For this study, the thermal behavior and envelop performance of an office building was investigated by means of infrared thermography.

A Practical Guide to Building Thermal Modelling. The development of thermal models is now an integral part of the design process, in particular to demonstrate compliance with the Building Regulations. In addition, project teams are increasingly being asked to commit to future energy use. analyzing the building from two perspectives simultaneously, it is aimed to find out if there is an observable correlation between comfort and energy aspects of the simulation.

In order to observe the change in the thermal comfort, the case building is. A preliminary dynamic thermal simulation is performed on a developed model of the PDEC high-rise office building.

The office building has a heavy thermal mass of lbm/ft 2 ( kg/m 2) and the time-of-use rate has an 8-h on-peak period (Morgan and Krarti, ). Figure Annual energy cost savings due to precooling relative to conventional controls as a function of R e.

To quantify their degree of influence, an existing tall office building was selected as a typical high-rise design for each of the climates and the energy use prior and after refurbishment was compared through computer simulations with DesignBuilder.

Existing buildings now represent the greatest opportunity to improve building energy performance. Building energy simulation is becoming increasingly important, because the simulation results can assist the decision makers to reach the solution quickly for improving building energy efficiency and reducing environmental effects.

Retrofitting existing office buildings offers significant opportunities the building envelope to resist thermal energy flow. The overall thermal transfer value (OTTV) is an index for comparing the information from the technical staff of the building.

Energy and Buildings is an international journal publishing articles with explicit links to energy use in buildings. The aim is to present new research results, and new proven practice aimed at reducing the energy needs of a building and improving indoor environment quality.

Energy is one of the most important catalysts in wealth generation, economic growth, and social development in all countries.

Buildings have a significant share in total energy consumed globally; therefore, they have a profound impact upon the environment. Energy is used in every stage of building life cycle (these stages are choice of locality, architectural design, structural Cited by: 5.

The energy used in non-domestic buildings accounts for 18 % of the energy use in the UK. Within the non-domestic building stock, 11 % of office buildings have a very high influence on the energy use. Thus, the retrofit of office buildings has a significant potential for energy efficiency and greenhouse gas emissions reduction within the non-domestic building stock.
