The practice of project close-out finalizes all project activities completed across all phases of the project to formally close the project and transfer the completed or cancelled project as appropriate. The purpose of project closeout is to assess the project, ensure completion, and derive any lessons learned and best practices to be applied to future projects.
Air duct leakage is the leakage of air from the air distribution system ductwork. The leakage can occur at joints, seams, and penetrations. Research shows that air duct leakage can be represented as a function of duct surface area, leakage class, and static pressure.
The kitchen hood captures smoke, grease, and other particles, mixed with air, above the kitchen appliance. An exhaust fan pulls the air from the hood through an exhaust duct. An exhaust fan pulls the air from the hood through an exhaust duct. The amount of air exhausted must be replaced by air brought into the building from a make-up air unit, or through the air conditioning or heating system.
The main benefit of Building Commissioning is cost savings. In addition to offering a financial return on investment, Commissioning (Cx) also results in reduced energy costs, fewer change orders, fewer contractor claims and call backs, a reduction in project delays, improved scheduling and better communication among the project team.
Reference to the U.S. Energy Information Administration resources; Healthcare facilities in the United States account for 4.8% of the total area in the commercial sector which is 6.5% in Europe. They are responsible for 10.3% of total energy consumption in this sector.
U.S. Department of Energy-funded study concluded that commissioning is indeed cost-effective for both new and existing buildings over a range of facility types and sizes, not only in terms of energy savings but also in non-energy benefits.
In order for your building's environmental systems to function according to plan, it is extremely important to make use of a TAB specialist. A certified TAB service will ensure that your system is installed properly and operating within the allowable parameters for best efficiency and performance. This guide will walk you through the ins and outs of TAB and why it is so crucial for your business.
Changes in building occupation patterns, and the ambitious plans for green recovery stated in governments recent announcements, are prompting organisations to stage plans for refurbishment of their buildings. Although not at the forefront for refurbishment-related decision taking, a well-maintained and safe pipework system is a key component of success in achieving a building’s refurbishment targets.
As part of its Healthy Economy strategy, USGBC has seven LEED pilot credits to help building teams provide healthy spaces, and to assist with re-entry. The pilot credits outline sustainable best practices that align with public health and industry guidelines related to cleaning and disinfecting, workplace re-occupancy, HVAC and plumbing operations.
Whether it’s happening in a small town an hour north of New York City or in a major metropolis in the south of Brazil, project teams achieving LEED Zero Water certification are building to the same ambitious goal: reducing their use of this increasingly scarce environmental resource to net zero.
Building commissioning costs are being shaped by the evolution of its practices and the problems encountered while commissioning is being performed. If we want to sustain the existence of commissioning and its future potential to grow and flourish, we must allow its costs to stabilize and prevent the costs from rising to unnecessary levels due to abuses, negligence and waste.
Small changes can mean big savings without sacrificing comfort. Keeping cool during a hot summer is essential, but energy costs can ramp up when the air conditioner is in high demand. A new study from the University of Georgia suggests there is a painless way to reduce energy costs: Turn up the thermostat. Even a degree or two makes a difference.
A recertification (recertification) shows how the building performs in operation in the areas: Energy, Water, Waste, Transport and Indoor Environment. The certification is renewed at least every three years and can be used to improve the building. Unlike LEED certification of new and remodeling projects, which is largely based on design documents, the recertification is based on how the building actually performs.
Washington, DC — The U.S. Department of Energy (DOE) on Wednesday announced a proposal that would allow new clothes washers and dryers that waste unlimited amounts of energy and water, raising home utility bills and carbon emissions.
Global warming and climate change are rising issues during the last couple of decades. With residential and commercial buildings being the largest energy consumers, sources are being depleted at a much faster pace in the recent decades. Recent statistics shows that 14% of humans are active participant to protect the environment with an additional 48% sympathetic but not active.
With the realization of industrial revolutions, the melting of glaciers in the world and the increase in global warming, human beings have to take some precautions. The process started with the Montreal Protocol in the 1980s, the Kyoto Protocol in the 2000s and then the Paris Agreement began to take measures for global warming with the participation of countries all over the world.
Stagnant or standing water in a plumbing system can increase the risk for growth and spread of Legionella and other biofilm-associated bacteria. When water is stagnant, hot water temperatures can decrease to the Legionella growth range (25–42°C).
Operations and maintenance (O&M) plan a plan that specifies major system operating parameters and limits, maintenance procedures and schedules, and documentation methods necessary to demonstrate proper operation and maintenance of an approved emissions control device or system.
Nowadays, a very large majority lives in closed environments. This closed environment is sometimes a closed volume such as a building and a structure, while it is sometimes located in closed spaces where logistics such as vehicles are provided.
As response to the coronavirus (COVID-19 or SARS-CoV-2) pandemic, REHVA experts drafted a guidance document on how to operate and use building services in areas with a coronavirus outbreak to prevent the spread of COVID-19 depending on HVAC or plumbing systems related factors.
Commissioning title is included in the Energy and Atmosphere title in the LEED Certification. In fact, although it has direct or indirect effects on credits in many titles, it shows its effect directly in two credits in the LEED Rating System.
