Green Building Audit

The building energy audit seeks to analyze the energy consumptions produced by a building with the aim of proposing measures to reduce them, as well as the related emissions and the economic cost of the energy used.

Green building and sustainable building both refer to the design and construction of buildings that have a minimal impact on the environment and using processes that are environmentally responsible, resource-efficient throughout a building’s life-cycle from siting to design, construction, operation, maintenance, renovation, and deconstruction. A green building: Makes efficient use of land, materials, energy, and water. Generates minimal or no waste. Provides a healthy indoor environment for its occupants.

• Commit to energy savings
• Assess current energy performance
• Prepare for a Green Building Audit
• Conduct an audit
• Quantify savings Potential
• Create an action plan & implement improvements
• Sustain & Continuously monitoring improvements
• Verify savings


Phases to carry out Green Building Audit:

1. Analyse the constructive and use characteristics of the building, in order to determine the real demand.
2. Determine the performance of the HVAC systems installed, in order to estimate the consumptions which satisfy the real demand of the building.
3. Evaluate the possibility of reducing the real demand of the building.
4. Evaluate possible measures to reduce the consumption of the system.
5. Evaluate and propose a list of measures prioritized according to the previous analysis, calculating the joint effect and its profitability, both in terms of reduction of the energy (primary and final) consumption and in economic terms.

It will be necessary to use a proper combination of the data obtained in situ with building performance models.
• Have enough precision to reproduce the monthly consumption.
• Have enough precision to evaluate the interest of the saving measures proposed.
• Be able to evaluate the influence of the variables not measured in the consumption.
