David Eldridge of Grumman / Butkus Associates present the ASHRAE Building Energy Quotient Labeling Program at the 2012 Chicago Energy Modeling Conference.
Benchmarking provides high-level comparisons of whole-building energy use but cannot identify where energy is used or determine cost-effectiveness of upgrades. Retroactive energy modeling uses submetering and hourly data to calibrate an energy model that can answer these questions. By identifying lighting was used 5 extra hours daily, submetering showed controls could save more than lamp upgrades alone in just a few months. Preparing for measurement and verification involves obtaining operational data, connecting submeters to monitor real-time use, and educating occupants on energy impacts to identify hidden problems and most cost-effective upgrades.

Energy Modeling of Dedicated Outdoor Air System, DOAS, for a Small Commercial...energytrustor
This document discusses a pilot project to evaluate the energy savings potential of replacing packaged rooftop units with dedicated outdoor air systems and heat recovery ventilation for small commercial buildings. Energy modeling of prototype office, restaurant, retail, and school buildings in different climate zones showed that the replacement strategy could reduce whole-building energy use by 30-40%. The first four pilot project sites - an office in Portland, an office in Corvallis, an office in Libby, Montana, and a restaurant in Corvallis - are highlighted. Lessons learned so far aim to reconcile predicted energy savings from modeling with actual in-service performance.
The North Texas IBPSA Chapter hosted an October meetup to discuss the new changes to the standard and how it impacts the energy modeling process.
The 2016 update of ASHRAE Standard 90.1 Energy Standard for Buildings is a major revision, containing more than 125 changes from the 2013 version. Together, Standards 90.1-2007, 90.1-2010, 90.1-2013 and 90.1-2016 produce almost 40% energy savings from the 2004 version. This slide deck is not comprehensive, but an overview of the Appendix G methodology.
This document discusses closing the performance gap between predicted and actual building energy performance. It begins with an overview of what the performance gap is and some of the key contributing factors. It then discusses current practices around TM54 guidelines and soft landings frameworks. The document also provides examples of how using actual operational data in building energy models, rather than standard profiles, can help improve prediction accuracy for lighting, equipment, and HVAC loads and energy use. Finally, it briefly mentions some future directions, such as decision making tools for urban planning and smart, model-based building control.

Principles of Energy conservation and auditssuserca5764
Energy audits are a systematic approach to measure and conserve energy usage. They identify all energy streams in a facility, quantify energy consumption, and indicate areas for improvement. Conducting energy audits helps comply with energy regulations and assess present energy usage patterns to optimize consumption levels. Different types of audits exist, from preliminary audits focusing on major equipment to detailed audits involving comprehensive analysis and engineering solutions. Lighting typically accounts for a large portion of commercial building energy usage, so audits examine lighting systems and opportunities to upgrade with more efficient technologies.

A printed circuit board (PCB) is a fundamental component in modern electronics that serves as a platform for assembling and connecting electronic components. It provides a solid foundation for the interconnection of various electronic elements, including integrated circuits (ICs), resistors, capacitors, and other passive and active components.
The construction of a PCB typically involves a thin board made of non-conductive material, often fiberglass reinforced with epoxy resin or other laminates. The surface of the board is coated with a layer of copper, which serves as the conductive material for the electrical pathways.
PCB design involves a meticulous layout of conductive traces, which form the pathways for electrical signals to flow between components. These traces are usually etched onto the copper layer through a process of chemical etching or mechanical milling. The layout of the traces is determined by the circuit schematic, aiming to minimize signal interference, optimize signal integrity, and ensure efficient electrical connectivity.
In addition to the conductive traces, a PCB features various other elements. These include pads and vias. Pads are small areas of exposed copper where electronic components are soldered onto the board. Vias are holes drilled through the board that connect different layers of the PCB, facilitating the routing of traces between them.
PCBs can have multiple layers, ranging from single-sided boards with components mounted on one side, to double-sided and multi-layer boards, which have components mounted on both sides and multiple layers of conductive traces sandwiched between insulating layers.
The manufacturing process for PCBs involves several steps, including design and layout, fabrication of the board itself, application of the copper layer, etching or milling of the traces, drilling of holes for components and vias, and finally, assembly of components onto the board through soldering or other methods.
PCBs are essential in a wide range of electronic devices, from simple consumer electronics like calculators and remote controls to complex systems like computers, smartphones, and medical equipment. Their compact design, reliability, and scalability make them indispensable in the world of modern electronics, enabling the creation of increasingly sophisticated and efficient electronic devices.

Solar Cooling Methods and Applications provides an overview of solar cooling systems and how to apply them. It describes two methods: photovoltaic (PV) panels that generate electricity to power a vapor compression chiller, and solar thermal panels that heat a fluid to power an absorption chiller. The document emphasizes that solar technologies have higher payback when the availability of the renewable resource matches the load, and that systems should be sized to maximize utilization of expensive components. It aims to help engineers understand when and how to apply solar cooling appropriately.
The document discusses life safety dampers, including codes, standards, and installation requirements. It covers seminars on codes and standards testing, damper fundamentals and installation, and air control integration. Fire dampers, smoke dampers, and combination dampers are described. Relevant codes, standards, and organizations like NFPA and UL are identified. Building code damper location requirements for occupancy separations, shafts, stairwells, and other areas are outlined.
This document discusses control dampers and their integration into building management systems for energy conservation. It covers damper basics, leakage, design for energy efficiency, and fire/smoke damper actuators. Control dampers regulate air flow through ducts and openings. Properly specifying low leakage dampers and modulating actuators can improve energy efficiency. International building codes require low leakage dampers and economizers.

Building Energy Labeling: What's the Point? A building energy labeling program provides information on the potential and actual energy use of buildings.Beyond the benefit received by individual building owners and managers, the increased availability of building data will be a valuable research tool for the building community.Building owners and operators can see how their building compares to peer buildings to establish a measure of their potential for energy performance improvement. Building owners can use the information provided to differentiate their building from others to secure potential buyers or tenants. Potential buyers or tenants can gain insight into the value and potential long-term cost of a building. Operations and maintenance staff can use the results to inform their decisions on maintenance activities and influence building owners and managers to pursue equipment upgrades and demonstrate the return on investment for energy efficiency projects.
You can’t change what you can’t measure.Informed decisions by purchasers and renters of property.Differentiation between peer group of high-performing buildings.
Current Efforts Related to Labeling• Significant efforts in the international community - European Union, Singapore, Canada and others• U.S. efforts include various rating systems:• EPA ENERGY STAR – Energy rating with baseline IEQ criteria• USGBC LEED – Sustainability rating• GBI Green Globes – Sustainability rating• BOMA 360 – Energy is one of six O&M-focused criteria• State programs– California, New York, DC, Massachusettes• ASHRAE is working with ENERGY STAR, DOE Energy Efficient Building Hub in U.S. and CIBSE internationally

The Coleman A. Young Municipal Center is a government office building in Downtown Detroit. The international style, high-rise building was constructed in 1951 and completed in 1954. It is 20 floors high, with one basement floor, for a total of 21. The building is used as a library, a court-house, a county government facility and as a city hall, replacing the now-demolished Detroit City Hall. McCormack:Built in the mid 1970s, the 21-story building is located directly across from Massachusetts State House and houses many state executive branches and state agencies. The building was designed as an open floor office building with minimal enclosed offices and a dedicated main frame information technology system. In addition, it was designed to provide comfort through a municipal steam fed mechanical system. Throughout the years, the building has experienced many changes, including change in the mechanical system, the floor spaces where individual offices and the main frame has been replaced by servers, desktop PCs and printers. City Hall Annex is a 4 story office building encompassing approximately 32,000 square feet. It is a LEED Gold rated building that was gutted and renovated about 6 years ago. The building has a ground source heat pump/forced air system, with no conventional backup. There is also a 26.5 kW solar PV system on the roof. City Hall Annex is located at 344 Broadway in Cambridge, MA.
