There are several types of pumps used in fluid transfer, but the most common used in today’s HVAC systems is the centrifugal pump. Types of centrifugal pumps include volute or axial flow pumps. The volute takes water from the impeller and discharges the water perpendicular to the shaft. A centrifugal pump with a diffuser casing (axial flow pump) discharges the water parallel to the pump shaft.
Centrifugal pumps are available in many types including circulator, single- and multi-stage end-suction, single- and multi-stage split-case, and vertical in-line pumps.
Circulating pumps are typically used in low pressure, low-capacity systems. The size of this system is typically under 150 gpm and not rated for more than 125 psig operating pressure. This type of pump is typically mounted directly in and supported by the piping system and is available with the motor in either the vertical or horizontal position. See Figure 1 for a standard circulating pump.
End-suction pumps are single-suction and can either be close- or flexible-coupled. A close-coupled pump has the impeller directly mounted to the motor shaft. A flexible-coupled end-suction pump has the impeller and the motor shaft separated by a flexible coupling. The benefit of using a close-coupled pump is that alignment of the motor shaft to the impeller is fixed. A flexible-coupled pump can become misaligned during maintenance. This can create issues if not properly reassembled by trained personnel. End-suction pumps are designed such that the incoming water enters the pump through the end in a horizontal manner. The water then changes direction and is discharged vertically, perpendicular to the suction. These pumps are typically installed on a solid base on the floor. An end-suction pump is capable of being used in HVAC systems with capacities up to 4000 gpm and 150 ft of head.
The advantage to using a close-coupled pump is that it requires less floor space within a plant room for installation. One of the disadvantages of using a close-coupled pump in an HVAC system is the motor type. The motor is typically specially matched to the type of shaft and the seals for the pump. Flexible coupled pumps typically use standard motors. See Figure 2 for a typical flexible coupled end-suction pump.
Split-case pumps are similar to end-suction pumps in that they are flexible coupled between the motor and the pump. The assembly, including the motor and pump, is rigidly mounted to a common base-plate. Pump suction and discharge are arranged in the horizontal direction and are perpendicular to the shaft.
Split-case pumps are available either in single- or double-suction. To be a single-suction pump, the water enters the impeller from only one side. For double-suction, the fluid enters the impeller from both sides. Using double-suction reduces the risk of hydraulic imbalance. The reduction of hydraulic imbalance is one of the reasons why double-suction split-case pumps are preferred over single-suction.
Split-case also may have multiple impellers for multi-stage operation. Multiple impellers provide increased available head within a single pump.
Split-case pumps are available as horizontal or vertical split-case. For horizontal split-case pumps, the impeller casing is split in the horizontal plane. For vertical split-case pumps, the impeller casing is split in the vertical plane. To have the casing split allows full access to the impeller for maintenance.
Split-case pumps are used mostly in fire protection systems but also have been used in the HVAC industry for large capacity systems. Their capacity range is up to 6500 gpm and 600 ft of head. These pumps are also available with increased operating pressures up to 400 psig. See Figure 3 for a typical horizontal split-case pump.
These pumps typically have a reduced footprint within a plant space and do not require inertia bases. Inertia bases are generally installed to reduce vibration from the rotating parts within the pump. discharge piping are arranged in the horizontal plane. Vertical in-line pumps are available as single- or double-suction.Vertical in-line pumps are close-coupled. The pump and motor are directly mounted on the pump casing. The pump is typically mounted and supported by the piping system in which it is installed. For larger capacity vertical in-line pumps, the pump assembly may be provided with a base for floor mounting. The pump suction and
Vertical in-line pumps have a capacity of up to 25,000 gpm and 300 ft of head. See Figure 4 for a typical vertical in-line pump.

There is a lot of buzz around intelligent buildings these days, but what exactly is an intelligent building? There are many interpretations and definitions.
An intelligent building is defined as a set of dynamically connected smart systems that are made interoperable through accumulating, sharing, analyzing, and acting upon the collective smart building data. When designed properly and effectively, the intelligent building platform will result in a more efficient, secure, and productive asset that has the capacity to continuously improve over its lifetime.
The intelligent building platform becomes a powerful tool, enabling optimal building performance across all metrics-life safety, security, energy efficiency, productivity, operational efficiency, utility consumption, sustainability, and conservation measures and employee and public engagement. The intelligent building design creates a common software platform that aggregates, normalizes, and coordinates the data from and between the disparate smart systems. This platform enables transparent access to real-time building performance data while allowing intuitive visualization of the metrics important to each class of stakeholder through dashboards. The capabilities of the platform are further expanded through the implementation of fault detection, diagnostics, analytics, and advanced reporting applications.
Often, a collection of independent smart systems has been considered “intelligent.” For example, a typical building design may incorporate efficient mechanical equipment with advanced control sequences or a smart lighting system will use LED fixtures, energy-efficient ballasts, and daylight harvesting strategies. While smart systems are an excellent step and important components of a smart building, until they are enabled to share their critical data to effectively impact other systems, they act as islands of information within the facility, limiting the opportunity to positively impact the overall enterprise. However, when enabled to share their specialized data, through an open-source data platform, these smart building systems become collectively intelligent and their effectiveness increases exponentially.
An intelligent building should be fit for purpose and fit for the future. It must meet the requirements and needs of the enterprise’s potentially vast group of stakeholders, addressing the goals and initiatives set forth in the customer’s charter and vision. Simultaneously, the intelligent building needs to be fit for future use, with the flexibility and scalability incorporated into the design to easily and seamlessly expand with, and adapt to, tomorrow’s technologies.
Seven steps to an intelligent building
Because a truly intelligent building necessitates a number of components working in concert, Environmental Systems Design has created a list of seven keys to intelligent building design and implementation. From the predesign phase to the evolving role of the facility manger in tomorrow’s intelligent building, these seven design keys will help any stakeholder plan for and execute the fit for purpose, fit for future principal throughout their intelligent building network.
1. Plan ahead. The intelligent building concept is best planned for in the early stages of design-the earlier, the better. Both timing and an informed, motivated end user are critical to the execution of an intelligent building. Once the infrastructure has been defined, it is typically difficult and costly to makes the necessary changes to achieve the maximum benefits. Knowing the consumption of each piece of field equipment to the most granular level possible is beneficial. An intelligent building will have metering points on all pieces of equipment including, but not limited to, electrical switchgear and distribution, primary water distribution, HVAC systems, vertical transport, and irrigation systems. When the base building systems aren’t designed for intelligence from day one, although not impossible, it is more challenging and costly to redesign and redistribute the mechanical, electrical, plumbing (MEP), fire protection, and information technology infrastructure to properly support and contribute to the intelligent building platform.
2. Identify and understand the wide-ranging stakeholder requirements. Each class of stakeholder will have different requirements in the intelligent building. The desired outcomes will vary depending on the individual, unique expectations, and experiences. Gathering these individual stakeholders to discuss their distinct and specific needs, including coming to consensus and compromising where necessary, will be critical to successful design. Intelligent buildings will need to take the following stakeholders into consideration:
All parties are interested in obtaining granularity in their specific areas so they can analyze the data gathered and optimize building systems according to best practices. Defining metrics helps apply the intelligent data gathered to minimize energy and operational expenditure.

A New York City (NYC) building will meet the challenge of reducing emissions by 90% to 100%. Our engineering team assumed that a new, mid-rise multifamily building may have the highest potential for cost-effective net-zero energy building design for the following reasons: easier adoption of new technologies, lower initial incremental costs, and optimal occupant density per roof area to maximize use of renewable energy.
Using the Dept. of Energy’s eQUEST, a sample building was created that mimics energy use of a typical new NYC multifamily building. The baseline model used simulation guidelines from a state energy program for multifamily buildings, as well as ASHRAE Standard 90.1-2007, California Title 24 ACM Manual, ASHRAE Standard 62.1-2007, and the NYC Building and Mechanical Code. This model served as the reference for assessing progress toward a net-zero energy building design.
The building has 48 apartment units within a 53,000-sq-ft gross floor area, in a rectangular shape, shown in Figure 1, with four floors plus a basement and a common laundry. The model was generated so that one can incrementally change the number of floors as needed.
In the baseline, two likely scenarios are examined: heating by electricity (with packaged terminal heat pump, or PTHP) and heating by fossil fuel (with packaged terminal air-conditioner, or PTAC, and gas-fired boiler) according to ASHRAE Standard 90.1-2007. New York Central Park’s TMY3 bin weather data is used in all the simulation runs.
The approach
Although a 90% reduction in emissions by 2050 looks like an intimidating target, it is possible to overcome the challenge following a “one step at a time” approach. This means breaking the target into smaller, achievable pieces instead of considering it as an insurmountable whole.
When selecting energy-efficiency measures, priority is given to measures that are smaller, passive (fewest moving parts), cheaper (more cost-effective), and innovative.
The passive strategies studied include: highly improved wall and roof insulation, window upgrade with low-e coatings and insulated frames, shading possibilities, and substantial infiltration reduction by eliminating penetrations through building skin and through detailed air-sealing. Diminishing returns are evaluated for these envelope strategies while also taking into account the lowered installed cost for mechanical equipment that results from higher-efficiency envelope measures. In the analysis, we compare compartmentalization versus noncompartmentalization practices, along with mechanical versus natural ventilation, and determine which ventilation solution provides the best controlled intentional fresh air into the apartment spaces.
A high-performance air-source heat pump (variable refrigerant flow, or VRF) is introduced as a heating plus cooling system. One VRF outdoor condensing unit is recommended per apartment to lower transport losses and piping costs and to free up roof space for renewable energy generation. Domestic hot water (DHW) energy efficiency strategies studied include heat recovery from the drain as a preheater and recovering the waste heat from the VRF system by a heat exchanger.
VRF systems offer multiple benefits including:
Lighting strategies include low lighting power density (LPD) design solutions while maintaining acceptable levels of illumination. Where applicable, occupancy sensors and bi-level lighting controls are evaluated.The most efficient available appliances are considered for apartments and common areas.
Solar photovoltaic (PV) arrays can be installed in the freed-up roof space to zero out the remaining electricity use after all other improvements are implemented. Using the eQuest simulation tool, numbers of floors are iteratively varied to determine the economically viable range of floors and also the highest possible number of floors for a building to achieve net-zero energy with today’s technology.
Electrical loads
Appliances and plug-load measures were evaluated first since they are the least recognized for reducing energy and one of the hardest to achieve overall cost-effectiveness. Evaluated products were the lowest energy users among Energy Star labeled products and tabulated as follows:

For years – approximately 15 since LEED certifications were introduced – much of the motivation for going green or adopting sustainability best practices has focused on cost savings from energy, water and other forms of conservation. The cost savings are real and valid and can add significantly to property value that is being appraised for acquisition or financing.
But appraisal, while a science, is also an art. Appraisers see buildings not only as bricks and mortar, glass and steel, but as activity hubs for tenants, visitors and employees. Buildings house people and the people who work, play, learn or reside within are also determinants of a building’s value.
It is not news that tenants prefer green buildings. What company wouldn’t prefer healthier, environmentally-friendly spaces with non-glare LED lighting, natural light, green spaces, recycling, water and other forms of conservation that enhance wellness and productivity? But the big question is: are tenants willing to pay the tariff for renting in a green building?
For a long while, green was rarely a crucial influence in a rental decision, location and cost being the ever-present decision-making factors. The early reality was that green buildings were expensive, time consuming, more difficult to build and often very technical. But times have changed.
Where once aesthetically pleasing green architecture was considered an oxymoron, today architects, engineers and constructors have embraced and become adept at green building.
Where once recycled green products were eco-ugly, cheap and unpleasant, today’s green products have increased in supply (recycled tire mats can be found in every big box store), decreased in cost and become eco-chic (take a look at the Coke, olive oil and pickle jar recycled glass countertops on Pinterest).
Earlier this month, the U.S. Green Building Council (USGBC) released the results of a survey, LEED and the Corporate Built Environment, that queried Fortune 200 companies and showed:
The above may be the case for large corporations, but what of the much more numerous and smaller public, privately-held companies and not for profit tenants? For that answer, another recently released study by DTZ (a full-service global leader in commercial property services) “shows that occupants in green certified buildings tend to be more satisfied than those in conventional buildings.” The study also founded that the greater the number of certifications a building has, the higher the level of tenant satisfaction, especially when green practices lower costs and improve services.
One of the challenges for an appraiser is to incorporate the growing desirability of tenanting in green buildings in tandem with the “soft” value of tenant happiness – elusive variables that can be neither easily understood nor easily measureable. One important stride for appraising green buildings is that the more there are, the greater the number of comparables.
Have we reached a point of a meeting of the minds between property owners and tenants where owners are convinced of the economic benefits of green practices concurrently with tenants who want to generate their own benefits of greater productivity, increased employee wellness and retention?
Certainly we have momentum in the marketplace. Tenant retention and faster absorption may always be determined by location and price. But huge strides in certifications becoming mainstream and better understanding of the many advantages of owning and/or occupying a green building means high-performance buildings are increasingly entering into tenant decisions and may well become the third important deal maker – or breaker – in commercial property leasing decisions.

Suas regras simplificam e incentivam a realização de negócios neste mercado
O mercado imobiliário está passando por um processo de transformação e inovação com as regras introduzidas pela recente Lei 13.097/15.
Entre as principais mudanças estão: a possibilidade de resolução extrajudicial do compromisso de compra e venda em razão do inadimplemento do comprador, sem necessidade de ação judicial; a concentração na matrícula de informações acerca de dívidas relacionadas ao imóvel e; a proteção especial aos adquirentes de unidades autônomas de empreendimentos imobiliários contra dívidas da incorporadora ou loteadora e seus antecessores.
No primeiro aspecto, a Lei, em seu artigo 62, sem correspondência na Medida Provisória n° 656/2014, dispensa a necessidade de ajuizamento de ação judicial para que se possa resolver, por inadimplência do comprador, os compromissos de venda e compra em que conste cláusula resolutiva expressa por inadimplemento. Nesses casos, o vendedor deve notificar o comprador, por meio de cartório de Registro de Títulos e Documentos, acerca das quantias em aberto (principal, correção monetária, juros de mora, eventual multa contratual e honorários advocatícios) para que este, em 15 dias, purgue da mora, sob pena de, não havendo o pagamento, resolver-se de pleno direito o contrato.
A alteração visa dar maior celeridade e reduzir os custos do procedimento de resolução contratual de compra e venda de imóveis, que, até então, segundo o entendimento jurisprudencial, dependia de intervenção judicial. Atendendo a antiga reivindicação das incorporadoras, passa a se permitir que estas, obtendo a resolução do contrato, rapidamente alienem as unidades inadimplentes a terceiros.
Desse modo, a orientação é que conste na promessa de venda e compra cláusula que especifique o procedimento e preveja expressamente a resolução do contrato para o caso de inadimplemento do adquirente.
A segunda mudança relevante encontra-se no artigo 54, referente à concentração na matrícula de informações acerca de dívidas que possam atingir o imóvel. A Lei afirma que os negócios que tenham por fim constituir, transferir ou modificar direitos reais sobre imóveis são eficazes em relação a certa dívida quando, ao tempo do negócio, não havia registro na matrícula fazendo alusão a esta.
O intuito principal é que o adquirente apenas precise averiguar a matrícula do bem quando for comprar um imóvel, dispensando-se que, como atualmente é praxe, requisite as certidões em nome do proprietário e antecessores do foro de seus domicílios e no foro do local do imóvel, para não ser surpreendido futuramente. O objetivo legal é conferir segurança jurídica aos negócios envolvendo imóveis, fomentando o setor. O que não constar da matrícula, em regra, não poderá ameaçar a propriedade do imóvel que está sendo adquirido.
Observando a questão pelo lado do credor do proprietário do bem, a Lei impõe que aquele que quiser ver seu crédito satisfeito por meio da constrição de certo imóvel, ainda que este seja futuramente alienado ou onerado, deve fazer constar na matrícula do bem o seu direito. Isso se aplica ainda que o credor tenha meramente ajuizado uma ação judicial que, ao final de sua tramitação, possa vir a se utilizar do imóvel para satisfação do direito reivindicado. Para que os credores procedam aos registros e às averbações nas matrículas dos imóveis, a Lei confere prazo de dois anos a partir da sua entrada em vigor.
Caso o registro não seja feito, o credor corre o risco de não conseguir se utilizar do imóvel para satisfazer seus direitos creditórios na hipótese do bem ter sido alienado ou onerado, atos que permaneceram eficazes perante o credor.
O dispositivo não se aplica às obrigações de caráter propter rem(relacionadas com a própria coisa, como, por exemplo, contribuições condominiais e dívidas de IPTU), ônus de caráter socioambiental, construtivo, urbanístico, cadastrais ou de licenciamento. Para esses casos, as diligências dos adquirentes para averiguação de eventual dívida ou irregularidade, ainda permanecem necessárias.
Importante frisar que a nova Lei está em consonância com a interpretação do Superior Tribunal de Justiça (STJ). Segundo o órgão responsável pela interpretação última da lei federal, para o reconhecimento da ineficácia do negócio por fraude à execução, é necessário o registro da penhora na matrícula do imóvel ou a comprovação da má-fé do adquirente.
Vale destacar que as dívidas constantes da matrícula não têm o condão de impedir a compra, mas fazem com que o adquirente tenha que se assegurar que o proprietário pode pagá-las, impedindo a tomada do bem no futuro.
O terceiro e último aspecto relevante ao mercado imobiliário é a proteção especial conferida aos adquirentes de unidades autônomas de empreendimentos imobiliários contra dívidas da incorporadora ou loteadora e seus antecessores. Para esses casos, previstos no artigo 55, o regime jurídico é ainda mais protetivo que o analisado anteriormente (do artigo 54), prevendo o dispositivo que negócios jurídicos de alienação e oneração de imóveis em empreendimentos imobiliários, registrados na matrícula, estão blindados contra à decretação de ineficácia e contra à evicção ainda que haja registro da dívida na matrícula do bem.
Observa-se que, no tocante aos bens de empreendimentos imobiliários, é assegurada não só a eficácia, mas também o âmbito da validade ao se inibir a evicção, que “é a perda da coisa em virtude de sentença judicial, que a atribui a outrem por causa jurídica preexistente ao contrato”. Assim, a blindagem atinge até mesmo riscos decorrentes, por exemplo, de restrições convencionais à livre utilização do imóvel, da fraude contra credores ou de nulidades anteriores na cadeia dominial.
Ainda mais importante é que tal proteção aos adquirentes não comporta exceção, ou seja, é conferida ainda que haja registro de dívidas na matrícula mãe do empreendimento antes do registro da incorporação/loteamento.
Diante do exposto, verifica-se que a Lei nº 13.097/2015 veio para simplificar e incentivar a realização dos negócios imobiliários, tanto no sentido de facilitar a resolução de contratos com parcelas atrasadas, quanto para conferir alta proteção e segurança aos adquirentes de imóveis.
