Energy Audit Seminar Report
The energy audit process starts with forming an appropriate energy audit team (EAT) that clearly specifies the audit scope. It is crucial for the team to look at the available resources to frame the time and budget for the audit and together all necessary building information before starting the audit. EA can be conducted at 3 different levels depending on the time, budget constraints, the building complexity, and client requirements.
In hot conditions, the EA process showed that the building was clearly improperly managed. In this study, the level 1 audit identified many opportunities to save energy; 6.5% of the annual building energy consumption is expected to be saved. In the level 2 assessment, 49.3% of the building energy consumption can be saved .Ultimately, 52% of the total energy can be saved if all the recommendations by the EAT are implemented.
In cold conditions, the majority of nursery and elementary schools of a particular region were audited in order to investigate their energy efficiency and indoor air quality. Despite the existence of various standards concerning the construction and operation of school buildings, the survey conducted here shows that almost all of the examined buildings are inefficient and fail to provide the recommended thermal and air-quality environment. Perhaps the most important conclusion arising from this study is that the large number of reported problems indicates that there is a lack of interest concerning energy efficiency and air quality problems in school buildings since no action has been taken for years in order to improve the situation. Possible measures include low-cost ones like the installation of lighting shelves for better solar and daylight control, the improvement of window air-tightness, and better lighting control. The installation of separate heat consumption meters and controls in many nursery schools would obviously provide economic benefits. The proper sitting of thermostats in all buildings could also provide significant energy conservation and contribute to a better internal thermal environment. Thermal insulation of the building envelopes and replacement of windows with insulated ones, equipped with double glazing are mandatory measures that lead to conformity with the existing legislation. The feasibility of other measures like thermal zoning, air handling and passive energy techniques should be investigated separately for each building, in order to provide the local authorities with the actions needed to improve the current situation, both in terms of energy efficiency and improving the indoor environment.
