The article offers information on technology, bolt/nut combinations, and other related factors for heating and ventilation piping and duct systems to ensure a building's safety highlighting modular mechanical seals. Modular mechanical seals can reportedly be used to permanently seal and protect pipes passing through concrete walls and other barriers. It notes that heating and ventilation engineers must review pipe and duct penetrations to identify which seal is the most suitable for a project.

The article provides tips for heating, ventilation, air conditioning, refrigeration design engineers in boiler replacement. Design engineers should give consideration for the completion of a hydraulic model analysis of the hot water distribution under all operating conditions. They should also check with the boiler equipment manufacturer when designing a primary-variable flow relative to minimum flow. Replacement of a boiler needs timing, as well as a temporary boiler.

The article offers tips for heat and ventilation engineers on how to replace a 20,000-cubic feet meters supply air system serving an office building. Engineers must have a Test and Balance firm document heating and ventilation existing conditions of the building. They must optimize the central air system's energy consumption as it pertains to the type of supply air system.

The article presents the author's comments on how engineers need to point out pitfalls in systems and apply their best assessment for building owners. The author suggests that based on their morals and ethics, professionals should make such a reputation that they can be counted on to assist in problem solving and/or raising awareness to a potential injustice without compromise. The author says that an engineer must look first for a reasonable solution to the problem.

The article presents information on the basics of heating and ventilation (HVAC) design and construction in a building. The Building Program (BP) document is created for desinging and creating the HVAC systems. Using the suggested Basis of Design (BofD) template, the HVAC engineer take the program information and then craft a BofD.

The article presents the author's views on various issues and trends related to the heating and ventilation (HVAC) industry in the U.S. These issues include testing, adjusting, and balancing (TAB) companies' failure to recognize the importance of HVAC systems, the possibility that hospital acquired infection will continue to be a problem, and the increase in the number of women in the building industry. He also provides information on a website that offers cooking instructions for engineers.

The author reflects on the importance of computer programs for the efficient calculation and technical design of heating, ventilation, and air-conditioning (HVAC) equipment. He cites the benefits of smart HVAC software, which helps engineers commission and design integrated program into another application associated with the HVAC application. Furthermore, the author encourages engineers to look beyond what computer programs can do to maximize that had been created on a specific job.

The article discusses the development of the BAS design for the commercial building heating, ventilation and air conditioning industry in the U.S. It states that BAS design is the responsibility of the design engineer and assigned to the temperature controls contractor. Experts believe that the scheme is also important in the construction industry systems integrator function as it reduces generic product specifications and allows designs to the actual product capabilities.

The article suggests that a testing, adjusting and balancing (TAB) firm be contracted as a third-party professional for the establishment of a buildings environmental engineering system. The duties of the TAB engineer would include: a design review of possible air and water balancing issues and concerns; the writing of a TAB specification; the production of TAB system flow diagrams; and the signing of field coordination drawings during the construction phase.

The article reports that National Institute of Standards and Technology (NIST) analysis of a recent EPA survey of 100 representative United States public and commercial buildings found that actual post-construction ventilation conditions are often different than expected based on the building design. The NIST researchers said such findings highlight the importance of early testing of a ventilation system's ability to achieve design intent. They noted instances where building engineers could not find ventilation system plans or found the ventilation system equipment itself inaccessible and urged building designers and operators to remedy the situations.
