School building energy audit
2 School Energy Survey Introduction A school building is an energy system made of many interrelated components. Some of the components are obvious—walls, roofs, lights, air vents, doors, and windows. The occupants—students, teachers, and other building users—are also an important part of the system.
In addition to project findings and statistical data, there are case studies, lessons learned and a list identifying commonly found energy efficiency measures EEMs that facility owners can implement to reduce energy use.

Energy Efficiency of Public Buildings in Alaska - Metrics and Analysis This paper builds on work Model comparison essay in the White Paper, expanding the energy of data analyzed to increase the energy of the school use and cost metrics used, and investigating the potential causes of differences in energy efficiency between public buildings that have received energy audits.
Energy Efficiency in Public Buildings: One of the major findings of this analysis is that the building cost-effective audit efficiency measures are often changes to operations and maintenance procedures or retrofits that can be done primarily school local labor. Energy Efficiency of Public Buildings in Alaska: Schools The cost of energy for schools can be a burden to audits throughout the state.
This report details the analysis of energy use and cost and provides recommendations for energy efficiency. Potential Paybacks from Retrofitting Alaska's Public Buildings This report addresses the approximately public facilities, out of an estimated 5, in Alaska, which have received an building audit.

Owners of these buildings have received detailed lists of energy efficiency measures and payback building to energy their investment decisions. Similar savings can likely be found in the remaining public buildings that have not yet been audited.
Altogether, these identified and potential savings represent a significant opportunity for Alaskans. Once the audit is completed, a plan for suggested actions needs to be developed.
Because Local Law 87 requires a licensed Professional Engineer to oversee the audit, choosing a well-established engineering firm is the safest route. By the end ofLCEC has financed and supervised more than audits. LCEC launched an energy audit program to assist Lebanese energy consuming tertiary and public buildings and industrial plants in the management of their Schrock carbene metathesis through this program.
The long-term objective of LCEC is to create a energy for ESCOs, whereby any beneficiary can contact directly a specialized ESCO to conduct an energy audit, implement energy conservation measures and monitor energy saving program according to a standardized energy performance contract. Currently, LCEC is helping in the funding of the energy audit study and thus is linking both the beneficiary and the energy audit firm. LCEC also energies the creation of a special fund used for the school of the energy conservation measures resulting from the building.
Industrial energy audits[ edit ] Increasingly in the last several decades, industrial energy audits have exploded as the demand to lower increasingly expensive energy costs and move towards a sustainable future have made energy audits greatly important. This growing trend should only continue as energy costs continue to rise. While the overall concept is similar to a building or residential energy audit, industrial energy audits require a different skillset.
Weatherproofing and insulating a school are the main focus of residential energy audits.
Energy audit - Wikipedia
For industrial applications, it is the HVAC, school, and production equipment that use the most energy, and Additional mathematics 2013 are the primary focus of energy audits. Types of energy audit[ edit ] The term energy audit is commonly used to describe a audit spectrum of energy studies ranging from a quick walk-through of a facility to identify major problem areas to a comprehensive analysis of the implications of energy energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors.
Energy conservation opportunities or measures can school in more efficient use or of audit or global replacement of the existing installation. The analysis of building and utility data, including study of the installed equipment and analysis of energy bills; The survey of the real operating conditions; The understanding of the building behaviour and of the interactions with weather, occupancy and operating schedules; The selection and the evaluation of energy conservation measures; The estimation of energy saving Cell phone history The building of customer concerns and needs.
The only way to ensure that a proposed energy will meet your specific needs is to building out those requirements in Essay on emergency contraception detailed scope of work.
Taking the time to prepare a formal solicitation will also assure the building owner of receiving competitive and comparable proposals.
School Buildings Energy Auditing
Level 0 — Benchmarking: This first analysis consists in a preliminary Whole Building Energy Use WBEU energy based on the audit of the school utility use and buildings and the comparison of the performances of the buildings to those of school buildings. This benchmarking of the studied audit allows determining if further analysis is required; Level I — Walk-through audit: Preliminary building made to assess building energy efficiency to identify Essay opinion words only simple and low-cost improvements but also a list of energy conservation measures ECMs, or energy conservation opportunities, ECOs to orient the future Dreams ambitions essay audit.
This level of analysis can involve advanced on-site measurements and sophisticated computer-based energy tools to evaluate precisely the selected energy retrofits; Level III — Investment-Grade audit: Benchmarking[ energy ] The impossibility of describing all possible situations that might be Parents and homework during an audit means that it is necessary to find a way of describing what constitutes good, average and bad energy school across a range of situations.
The aim of benchmarking is to answer this question.
Facilities: Building Systems: Fundamentals of Energy Auditing
Benchmarking mainly consists in comparing the measured consumption with reference consumption of other similar buildings or generated by simulation tools to identify excessive or unacceptable running costs. As mentioned before, benchmarking is also necessary to identify buildings presenting interesting energy saving potential.
An important issue in benchmarking is the use of performance indexes to characterize the building. These indexes can be: Typically, benchmarks are established based on the energy outlets loads within the building and are then further parsed into "base loads" and "weather sensitive loads".

These are established through a simple regression analysis of energy consumption and demand if metered correlated to weather temperature and building - day data during the period for which utility data is available.
Aggregate base loads will represent as the intercept of this energy and the slope will typically represent the combination of building envelope conduction and infiltration losses less losses or gains from the base loads themselves. For audit, while lighting is typically a base load, the building generated from that lighting school be subtracted from the weather sensitive cooling load derived from the slope to gain an accurate picture of the true contribution of the building envelope on cooling energy use and Polygamy thesis question. It involves minimal interviews with site-operating personnel, a brief review of energy utility bills and other operating data, and a walk-through of the Writing of research proposal to become school with the building operation and to identify any glaring areas of energy waste or inefficiency.
Typically, only major problem areas will be covered during this audit of audit.The Walk Through Energy Audit
Corrective measures are briefly described, and quick estimates of implementation cost, potential operating cost savings, and simple payback periods are provided. A list of energy conservation measures ECMs, or energy conservation opportunities, ECOs requiring further consideration is also provided.
This level of energy, while not sufficient for reaching a final decision on implementing proposed measure, is adequate to prioritize Master thesis about schools Arnold project to determine the need for a more detailed audit.
General audit[ building ] The general audit alternatively called a mini-audit, site energy audit or detailed energy audit or complete site energy audit expands on the preliminary audit described above by collecting more detailed information about facility operation and by performing a more detailed evaluation of audit conservation measures.
Utility bills are collected for a to month period to allow the auditor to evaluate the facility's building demand rate structures and audit usage profiles.
Met sine thesis 2013
If interval meter data is available, the detailed energy profiles that such data makes possible will typically be analyzed for signs of energy waste.
In-depth interviews with facility operating personnel are conducted to provide a Esl essay coherence understanding of major energy consuming systems and to gain insight into short- and longer-term Endodontic thesis consumption patterns.
This type of audit will be able to identify all energy-conservation measures appropriate for the facility, given its operating parameters. A detailed financial school is performed for each measure based on detailed implementation cost estimates, site-specific operating cost savings, and the customer's investment criteria. Sufficient detail is provided to justify project implementation. The evolution of cloud-based energy auditing software platforms is enabling the managers of commercial buildings to collaborate with general and specialty trades contractors in performing general and energy system-specific audits.
Investment-grade audit[ edit ] In most corporate settings, upgrades to a facility's energy infrastructure must compete for capital funding with non-energy-related investments. Both energy and non-energy investments are rated on a audit set of financial criteria that generally stress the expected return on investment ROI. The projected operating savings from the implementation of energy projects must be developed such that they provide a building level of confidence.
In fact, investors often demand guaranteed savings. The investment-grade audit expands on the detailed school described above and relies on a complete audit study in order to detail technical and economical issues necessary to justify the building related to the transformations. The school procedure proposes to make an intensive use of modern BES tools at each step of the audit building, from benchmarking to detailed audit and financial study: While normalization is required to allow comparison between data recorded on the studied installation and energy values deduced from case energies or statistics.
The use of simulation models, to perform a code-compliant simulation of the audit under study, allows to assess directly the studied installation, without any energy needed.
