Building Management Systems (BMB) keeps health facility’s HVAC components in check

In this health facility in Allentown, PA hundreds of mechanical components are connected by a modular control network that now serves the 36,000-sq-ft, two-story building. 

The building relies on a system involving a geothermal component, chilled beams, and a single-pipe distribution system tied to advanced mixing blocks.

Penn Foundation Project

Geothermal systems were installed that harvest energy from the earth. But the real uniqueness of this job is the way Btus are removed from or delivered to enclosed spaces. Different water temperatures are readily available for a variety of terminal units throughout the facility from a single-pipe system because we’re using new, off-the-shelf injection mixing blocks that blend supply and return water temperatures from the main. Injection mixing provides the perfect balance of everything designers, installers, and building owners most want.

A project like this is simplified only when the control system is ideally suited to all of the components that must work in tandem. With a BMS monitoring the overall performance, the design has helped the facility save on both energy and maintenance costs. Read more: http://bit.ly/1l4EQHG

Hydronic Systems Provide Better Energy Efficiency

By Greg Cunniff, Taco’s Applications Engineering Manager

Today’s HVAC industry offers a number of choices when it comes to providing heating and cooling in a large building: the three basic methods to provide comfort and move Btu around a building are by using water, air or refrigerant.

In our next series, we’ll compare these types of comfort systems. We’ll start by examining the energy efficiency issues. ASHRAE building in Atlanta offers an interesting opportunity for systems performance comparison: 

The energy consumption of any HVAC system is comprised of two components: equipment that generates heating or cooling and equipment that distributes it. The energy needed to generate heating and cooling commands the majority of energy consumption in an HVAC system, but the energy required for distribution is significant. It can take 40% of total electrical cooling energy demand to move Btu in an air system, 30% in refrigeration systems and 20% in hydronic systems.

The challenge of comparing the energy efficiency of HVAC systems always has been to take both the distribution and generation components into account while using the same set of test criteria.

Smart Farming with a Smart Hydronic System

By Jeff Pitcarin, Eastern Commercial Regional Manager at Taco, Inc.

To a  chicken farmer Earl Ray Zimmerman of Lancaster County, PA, keeping his 30,000 broilers (chickens for meat) warm at a steady temperature is critical to his profit picture. Sustainability is at the top of his list, too, so Matt Aungst of Total Energy Solutions, LLC teamed up with Taco to create a sustainable, precision hydronic chicken house heating solution. Matt used Taco’s free Hydronic System Solutions® software to design the system.

The advanced hydronic biofuel heating system conditions two 500-f. chicken houses. Each building contains up to 30,000 birds.

The new heating system resulted in significant cost reduction, production increases for the farmer, reduction of water-source pollution, as well as health and living condition improvement for the animals.

Better Buildings, Better Working Environments

Better Buildings = Better Working Environment

What does it take to create a better working environment? Designing greener buildings for the benefit of the people who work in them means providing better space organization, bringing ample fresh air, getting natural light into the building.

In the Taco Innovation & Development Center, our major focus of renovations to the existing Taco building was creating a more open, collaborative work environment for all departments. In this new video, the project’s architect Steve Decatur and interior designer Kate Ducat of Baker Design Group addressed the building’s core design objectives and energy-efficient lighting technology: http://bit.ly/TwTM8n

Building Retrofit for Energy Efficiency and Better Comfort

When the owners of Tanque Verde Apartments in Tucson decided to upgrade mechanical systems, they made it clear that they wanted a dramatic shift from old to new. Until recently, the 15 acre, 428-unit complex has met the heating and cooling needs of the tenants, but with little regard for the amount of energy consumed in the process.

When the apartments were built 30 years ago, energy efficiency wasn’t exactly the main focus. After all, the price for gas and electricity was a fraction of today’s rate.

At Tanque Verde, an enormous district system heated and cooled all the apartments. Last year, the hydronic system began leaking underground. Tenants complained about lack of controllability while repair bills accumulated. Making matters worse, the equipment was outdated, bandaged and in desperate need of replacement.

Keeping it all In-House 

When it comes to overhauling colossal mechanical systems, the Scotia Group Management LLC was quick to embrace the idea of a retrofit. Their mechanical contractor Oracle Control Systems, Inc. (OCSI) designed and installed all new hydronic heating and cooling equipment, solar-thermal DHW system, modular building automation controls, and large photovoltaic arrays to bring Tanque Verde out of the mechanical Stone Age.

“We’ve re-piped several properties in the summer without displacing tenants” Mo Forrey, owner of Oracle Control Systems, Inc. (OCSI).

OCSI crews tore out and replaced boilers, chillers, and underground hydronic lines. The two original mechanical buildings were kept; the smaller on the north side of the complex, and the larger on the south. Since none of the tenants could be displaced, OCSI installed parallel piping throughout the property while keeping the existing system on-line. Temporary chillers, boilers and piping were employed to maintain service.

On the north side of the complex, a similar approach was used. The mechanical building had a large atmospheric boiler and three vertical water heaters for DHW, all of which were removed. Now the building houses two, 1,000 MBH gas boilers and one large chiller. Hydronic demands for the smaller system are 140 GPM on the heating side, and 280 GPM for cooling. Each mechanical building is outfitted with a Taco iWorx boiler control module (BLMC). Each module can monitor and control up to four boilers, as long as the boilers are serving a common load.

Why Green is Good for People, Part 2

Why Green is Good for People? 

By Lynne Phipps, Taco Contributing Editor

Lynne Phipps, LEED AP

As discussed in Part 1, designing green buildings for the benefit of the people who live and work in them means bringing ample fresh air and natural light into the building and avoiding the use of materials that off-gas substances that are detrimental to human health and well being.

In addition, green indoor environments are both physically and psychologically comfortable for people.

Such design may include:
• The use of smart switches and thermostats for lighting and temperature control.
• Comfortable forms of heat such as radiant heat.
• The use of color, texture, and plants as interior design elements.

The use of technologies such as smart switches, which control lighting based on natural light levels as well as the presence of people in a space, is energy efficient and maximizes the use of natural light. Both factors make the environment more comfortable and healthier for human beings.

Smart thermostats provide similar benefits by regulating temperatures based on the availability of the sun’s thermal energy for heating. Both of these technologies are wonderful advancements. Any time the designer can reliably regulate the indoor environment to improve physical or psychological comfort, the individuals in that environment feel more supported and, as a result, happiness and productivity increase.

The use of color and texture, whether as paint, wall coverings and floor coverings, or as art work, also increases comfort and happiness indoors. In the work environment, this translates to decreased absenteeism and job turnover. It has been reported that second only to salary, the work environment is the most important factor in an individual’s decision to take a given job or stay with a company.

When designing a green building, the use of color is a craft. The designer must juggle the use of color with the ability of that color to reflect rather than absorb the natural light entering the space. Color also brings life to spaces and offers opportunities to add or reinforce a sense of identity, should the designer choose.

Likewise, plants can have a significant positive effect on the indoor environment. Studies have shown that one plant per person significantly increases CO2 in an indoor environment, decreasing absenteeism and reducing stress at work.

All of these elements — natural light, effective temperature control, color, the use of plants – contribute to the successful greening of buildings, whether new construction or retrofits.

Lynne Phipps is an interior architect and green building advocate with a holistic, integrated approach to the built environment.
