Existing Building Commissioning
The majority of existing buildings have not undergone any type of commissioning or quality assurance process. Over time building performance degrades due to operational and occupancy changes. Most buildings are performing well below their potential, use more energy than necessary and cost more to operate than they should. Existing building commissioning involves investigating, analyzing, and optimizing the performance of building systems through operational and maintenance improvement measures and ensuring their continued performance. The process assists in making the building systems perform interactively to meet the owner’s current facility requirements.
Energy Audits (Levels I, II and III)
Why get an audit? Most existing buildings don’t perform as well as they could. The cost of energy to heat, cool, and light buildings is skyrocketing. An Energy Audit by HEA is the most cost-effective way to define exactly how your energy is being used, where it is used effectively or wasted, and the full range of opportunities you have to take action to reduce your costs. HEA surveys and documents your building’s energy usage through a precise, hands-on, and systematic process. We prepare a detailed Energy Profile of your heating, cooling, lighting and water usage systems, and all other equipment that significantly affects your energy consumption. A wide variety of factors, from past usage and maintenance practices to weather data, can be incorporated to provide you with a clear and complete picture, along with descriptive narratives to ensure that all the data is easy to understand. HEA follows the ASHRAE – Procedures for Commercial Building Energy Audits guideline for performing energy audits.
