Building Enclosure Commissioning (BECx)

Posted by Nick Chiarelli on Aug 16, 2018 3:25:00 PM

Why Building Enclosure Commissioning (BECx) is crucial

Ensuring that a building’s enclosure is adequately designed and installed is a major factor in how well the building will ultimately perform. A building’s performance can be measured in a number of ways, but the safety and comfort of the end user should always be number one.

All building owners need to evaluate whether their new building should implement the BECx process. Why?...

Collaboration in Revit MEP/Architecture

Posted by ENGVT on Aug 8, 2018 11:01:42 AM

Revit MEP / Architecture Solves Collaboration Issues

As buildings become more advanced to meet energy and water use goals, such as those outlined in the LEED and Architecture 2030 Challenge platforms, the design of MEP systems must be able to react to changes in the overall building design throughout the design process. This will ensure that the MEP systems are properly sized and take into account the inevitable load variations throughout the building.

Understanding the importance of real-time coordination between MEP engineers, architects and construction managers means taking advantage of software tools that exist on the market today. Luckily Revit has been designed with collaboration in mind, by including powerful and efficient tools that make communication between disciplines understandable and easy.

Improving Commercial HVAC Efficiency

Posted by Nick Chiarelli on Aug 7, 2018 8:36:37 AM

5 Systems to Consider for Improved Commercial HVAC Efficiency

As a building owner, one of the greatest expenses is the cost of heating and cooling a building. While it can be easy to simply accept this as a necessity, it should be known that there are ways to improve commercial HVAC efficiency and reduce the cost of utilities, leaving money to be spent elsewhere in the building.

The upfront cost of a system upgrade can often be offset by the dollars saved using less electricity, gas, oil, propane, or other energy source. This payback period can be evaluated during the initial conceptual phases of the project by most mechanical engineering firms through energy modelling computer software. This allows you to evaluate the feasibility of possible upgrades before jumping into any commitments.

Bringing Value Back to Consulting Engineering

Posted by Jerry Chabot on Aug 6, 2018 2:16:00 PM

A Hard Look AT Consulting Engineering CYA Notes And 3 Tips To Avoid Them

I recently discussed the lack of perceived value in the architectural and engineering consulting business (AE) in a previous blog post. The problem statement was: Why are fees and services declining relative to other players in the construction space?

I previously mentioned that our industry’s pivot away from a primary focus on quality deliverables to a primary focus on managing liability has negatively impacted both our culture and our value to our customers and end users.

A "Race to the Bottom" in Consulting Engineering?

Posted by Jerry Chabot on Jul 9, 2018 1:36:41 PM

Returning Value to the Consulting Engineering Profession

I was recently sent this article from the Architectural Record by one of my consultant friends with whom I often commiserate about the struggles of being a design professional in today’s market. The article discusses the “race to the bottom” in the past ten years or so by the professional consulting industry (just replace the word “architect” in the article with “consulting engineer” and all the themes still apply).

PSC vs ECM Motors In Commercial HVAC Systems

Posted by Pete Gagnon on May 16, 2018 11:08:00 AM

ECM Motors = Energy savings and added functionality

ECM motors are providing a variety of benefits to commercial HVAC systems over traditional PSC motors. These motors are used in pumps, fans, and increasingly in compressors and other motor applications. An ECM pump or fan motor is electrically commutated, which means it uses a DC circuit controlled by an internal microprocessor to vary the speed and torque of the motor to match changing system requirements. 

PSC motors, or permanent split capacitor, use non-polarized capacitors and brushes to deliver electricity to the rotating parts. These brushes are known to wear out over time. ECM motors do not use brushes, thereby reducing maintenance and extending service life.

Museum Air Quality and HVAC Design Part 5: Equipment Location

Posted by Nick Chiarelli on Apr 9, 2018 11:49:07 AM

4 Benefits of Properly Located HVAC EquipmenT

The potential hazards and maintenance efforts associated with poorly located HVAC equipment can be a perpetual battle for facility managers and building maintenance staff.

If HVAC equipment is difficult to access, it is less likely to be properly maintained. Inadequate maintenance leads to component failure, which can be catastrophic in a museum setting.

Intro To HVAC Economizer Systems

Every building owner wants a lower energy bill. With museum applications in particular, implementing energy saving measures or selecting HVAC economizer systems first requires a full understanding of the system’s capabilities and potential effects in order to avoid negative impacts to the building, its occupants, and its artifacts.

Museum Air Quality and HVAC Design Part 3: Condensation Prevention

Posted by Nick Chiarelli on Apr 9, 2018 11:48:25 AM

HVAC Equipment and Tricks For Condensation Prevention

HVAC design for museums in cold weather climates often requires an attention to detail that's typically not necessary when humidification is not a factor.

Because cold, dry, outdoor air must be heated and humidified prior to discharging into the gallery space, and because exterior windows and mullions have the potential to get colder than the space dew point, special care needs to be taken to ensure that condensation does not form on these elements.
