Building Audit

BuildingAudit_01

The need to minimize its carbon footprint and enhance energy efficiency is of paramount importance to any successful organization. On that account, energy audits now play a pivotal role in which the energy use of the building will be inspected and evaluated prior to decision-making in the area of energy management, since you cannot manage what you do not measure. A comprehensive energy audit ensures that all energy streams and usages are quantified.

Preliminary Energy Audit

A basic preliminary energy audit involves an evaluation of utility data, site visits and field inspections of the building and its systems, to recommend simple energy conservation measures with calculations on expected annual energy savings. The system audit is an elaborate analysis on the performance of major energy system such as chiller plant room system and hot water system. Instruments are set up after the necessary site preparations, to acquire data for evaluation.

Detailed Audit

The detailed audit is the most complex energy audit type in comparison. It assesses all of the energy intensive systems in a building, and identifies opportunities for improvement in the building, such as retrofits and optimization works. All of our chiller plant audits follow international standards (ASHRAE Guidelines 14, 22 and AHRI Standard 550/590) where applicable. We carry out an error analysis before the start of each audit, to ensure that the plant efficiency is kept within 5% of its true value.

Measurement and Verification

In order to quantify savings from retrofits and optimization works, we carry out Measurement and Verification, which measures performance of the equipment, before and after the implementation works. Using this data, our engineers can carry out further fine-tuning of the equipment operations, to maximise the energy savings for clients.
