Essential to the development of a low carbon economy will be the advancement of building product and process to reduce the capital and whole lifecycle cost of low, zero and net-positive energy buildings to allow these structures to be realized at a greater rate. On the whole, the built environment is responsible for one of the largest fractions of global energy consumption and thus anthropomorphic climate change, a result of the greenhouse gas emissions from power generation. When one also considers the energy required to design, fabricate, transport and construct the materials necessary to bring new building stock online, keeping pace with the rapid trend towards urbanization, the importance of the built environment in the energy sustainability equation is clearly evident. Yet, while technologically feasible, the realization of carbon neutral buildings is encumbered by the perception of increased annualized costs for operation and a greater upfront investment. This paper will review the design case of the Masdar International Headquarters, the flagship building of the net-zero carbon emission Masdar city currently being developed within the Abu Dhabi Emirates. Specifically, how an integrated approach enabled by computer simulation early within the design process allowed for improvements in economy and efficiency, setting a model for future high performance buildings. The five-story, 89,040-square-meter office building will incorporate eleven sculpted glass environmental towers to promote natural ventilation and introduce daylight to the interior of the building. These towers will also serve as the structural support for one of the world's largest building integrated photovoltaic arrays, sized to supply 103% of the building's total annual energy requirements while protecting the building and roof garden from intense heat and solar gains. Moreover, by integration into a separate structural trellis system, clean energy can potentially be generated to offset construction requirements while dually shading workers below during the heat of the day. This, along with other key sustainability design strategies such as a solar powered central district cooling system, thermoactive foundation piling, underfloor air distribution, desiccant dehumidification, a nanotechnology enabled building envelope and smart grid enabled facilities management infrastructure will allow the Masdar Headquarters to reach carbon neutrality within a decade, allowing for the remaining century of its operation to serve as a platform for clean energy generation. © 2010 by ASME.

The U.S. Green Building Council (USGBC) will be launching the latest edition of the Leadership in Energy and Environmental Design (LEED) rating system (LEED 2012) across all certification types. LEED 2012 used commissioning prerequisites and credits as well as Measurement and Verification credits to place more of an emphasis on building performance and verifying actual metered data. A new prerequisite is that at a minimum, energy consumption must be tracked at one-month intervals or in accordance with utility billing intervals. Enhance commissioning intent remains the same as in LEED 2009, which includes verification of documents created as a part of fundamental commissioning as well as completing contractor submittal reviews. Advanced energy metering outlines the installation of advanced energy metering for all whole-building energy sources and major end uses that represent 10% or more of the total annual building consumption.

Data center design has always been associated with words like availability, reliability, and precision cooling. Although availability and reliability remain critical, energy efficiency, flexibility, scalability, speed to market, and cost effectiveness are driving modern data center design. The Digital Chicago Datacampus took advantage of efficiency improvements made possible by improved server equipment thermal tolerances, which open up the opportunity to condition a data center space without mechanical cooling for significant portions of the year in a wide range of climates. The campus also integrates the efficiency improvements with the concepts of modularity, repeatability, and speed to market. The result is a final product that was not only reliable and energy efficient, but also relatively simple to build, operate, maintain, and expand. Copyright 2014 ASHRAE.

Several steps that are followed to create an energy-efficient design for a Chicago's Rush University Medical Center (RUMC) are presented. The first step in creating an energy-efficient design is to perform a thorough analysis of the hospital's goals and functions and the next step is to research all applicable national and local codes and standards. ASHRAE standard 170 will be the first national standard to specifically deal with hospital ventilation and infection control. Environmental System Design Incorporation (ESD) performed a building analysis that examined energy usage at Rush's existing hospital and determined that energy was being used at a rate of 5.5-W/sq ft in the 30-year-old facility. The ESD design team went to the Philips factory to test 20-W LED and verify their lumen output prior to specifying them at Rush. The T8 and T5 lamps have different specifications but the light output per unit length is almost identical due to lamp behavior in different ambient temperatures.


Building systems data can be used to manage equipment operations and determine how to run the building more efficiently. Owners of a multitenant building may install meters in each leased space to determine how much energy is being consumed per tenant. Metering energy use will provide the information operators need to make informed decisions and provides essential information to the commissioning agent when recommissioning or retro-commissioning a building. Green rating systems, such as the U.S. Green Building Council's LEED program, recognize the essential role of meters as a feedback mechanism for the operation and maintenance of a building, and they award points for carrying out a proper measurement and verification (M&V) plan, which may include realtime energy metering. The most common standard used for M&V is the International Performance Measurement and Verification Protocol (IPMVP), available from the Efficiency Valuation Organization.

Experts suggest that significant benefits can be realized from properly designed rainwater harvesting systems. They suggest that such alternative water source systems (AWSS) need to be designed and sized by design professionals possessing either a Certified in Plumbing Design CPD) certification from the American Society of Plumbing Engineers (ASPE) or a Professional Engineer (PE) license. The roof is a critical component of the rainwater harvesting system and will define some of the other system components, such as filtration. Recommended roofing materials to achieve these objectives include standing seam metal, ethylene propylene diene monomer (EDPM), and slate or tile. The rainfall rate used for designing roof drainage systems is also related to the average frequency of occurrence and the time that it takes runoff to reach the collection device from the most remote portion of the contributing roof area.


Booster pumps elevate water pressure and flow in plumbing systems and help in meeting the water requirements of larger facilities. Packaged booster pump systems help large facilities meet the unique pressure and flow demands required of their plumbing fixtures, specialized plumbing equipment, irrigation systems, and HVAC equipment. The booster pump moves booster pump moves building's water source to the plumbing distribution system by increasing the water pressure. A booster pump is required by code when the water pressure from the local water source is unable to meet the required flow pressures at the fixtures. It is expected that booster pumps will become more common in residential buildings and to increase in size due to increased pressure requirements. It is also expected that critical and institutional facilities will require commissioning on all booster pump installations.


Benchmarking, an energy performance comparison, can boost energy efficiency and lower building operating costs. Benchmarking involves measuring and rating a building by comparing it to a standard. Some owners and managers collect energy data for their entire portfolio of buildings, calculate the energy use intensity (EUI), which is energy consumed per square foot, and then choose a baseline as the year with the highest consumption. One of the most widely used energy benchmarking systems in the United States is Energy Star Portfolio Manager, a free Web-based tool maintained by the U.S. Environmental Protection Agency (EPA). Users input basic building parameters, such as space type, square footage, hours of operation, number of occupants, and number of personal computers (PCs), as well as 12 months of total energy data. The National Institute of Building Sciences is establishing a High-Performance Building Data Collection Initiative to determine a methodology for collecting and disseminating energy and building attribute data.
