Building Envelope Testing

What Is Building Envelope Testing?

Building Envelope Testing is a way to quantify, good or bad, the amount of air infiltration or leakage a new or existing building has. A blower door is used to induce a positive or negative pressure on a building so that air leaks can be more easily identified and measured. These measurements are used to determine the level of tightness a building has achieved.

Why Building Envelope Testing?Blower Door

Building Envelope Testing, Blower Door Testing, and Envelope Commissioning are all terms used to describe this process. High efficiency HVAC Systems are becoming the “norm” when designing a constructing a new building. To take full advantage of these systems, they need to be installed into a well-constructed, “tight” building. The building envelope is typically described as having three main components:

  1. The Air Barrier
  2. The Vapor Barrier
  3. The Conduction Barrier (insulation)

All three of these components play in critical role in constructing a tight building. For years, buildings have been designed with adequate conduction barriers. However, even today many design and construction techniques lack the critical air and vapor barriers. This “weak link” in the building envelope chain means equipment runs longer, occupants are less comfortable, and buildings are much more vulnerable during extreme weather conditions.

Building Envelope Testing offers a way for building scientists to identify, document, and quantify the level of tightness a building has achieved. A tight building envelop has a direct effect on lowering energy costs, providing better comfort for occupants, minimizing runtime on HVAC equipment, and limiting many other issues associated with a leaky building. We believe the blower door has become one of the most powerful tools when it comes to validating construction quality. Simply put, blower door testing is the best way to ensure your new or existing building can reach is intended potential.

Thermal Imaging

What Is Thermal Imaging?

Infrared Thermal Imagers transform heat emitted from an object’s surface into useful visual data. Thermal Imaging is the art of decoding these images and providing meaningful insight into the data gathered.

Why Thermal Imaging?

Thermal ImagingThose who understand their potential have used Thermal Imagers for decades. Recent increases in energy costs and an overall shift towards higher efficiencies have placed thermal imagers back into the building science discussion. However, there is nothing new about their potential. In the hands of an experienced thermographer, these imagers become a powerful tool in areas such as equipment preventative maintenance, diagnostics and troubleshooting, roof leaks, building envelope testing, and much more.

We often use the thermal imager in conjunction with the blower door to help easily and quickly identify air and thermal breaks in new and existing building(s). At the same time, we’ve had success diagnosing everything from water leaks to misaligned pumps, motors, and impellers.

A thermal imager should not be used as rigid, definitive proof of a situation or scenario. Rather, a qualified thermographer should use the imager to help point the construction team in the right direction, at the right location, quickly and easily.

Building Commissioning

What Is Building Commissioning?

Commissioning is the process of identifying and documenting your needs for your building, and then providing the process, tools, and solutions to meet those needs.

Why Building Commissioning?Commissioning

Commissioning is a quality-control process that ensures buildings are planned, designed, constructed and operated according to your requirements. Simply put, commissioning is the most effective way for your building to reach is maximum potential.

Commissioning is quickly becoming commonplace in the construction and energy industries. Why expose yourself to the unnecessary risk of undertaking a project without having a third party advocate for you? In terms of payback; we have countless examples of commissioning paying for itself by identifying issues with design/installation that would have otherwise gone unnoticed. Once the one year warranty period is over; you’ve just inherited every issue that was not identified during the project. Commissioning is your best weapon against this.

The commissioning process is outlined in several phases. The first—and most important—step in the commissioning process is finding out exactly what your goals are so that we can utilize our services to meet those goals. Talk to us about your needs; conversations are free—change orders aren’t.

Maintenance Consultation

What Is Maintenance Consultation?

Identifying current preventative maintenance procedures, then consulting on corrections and/or improvements during the process. Typically related to improving energy efficiencies, maintenance consultation provides overall cost-reduction to building operators and owners.

Why Maintenance Consultation?

Maintenance ConsultationZH Commissioning realizes that even after successful project completion, building owners and operators are tasked with providing long-term preventative maintenance solutions. Typically, that solution comes via one of two ways; in-house maintenance staff or a preventative maintenance (PM) contract.

ZH Commissioning is excited to provide a new solution for preventative maintenance challenges: PM Consultation Services. While each service will vary depending on your exact needs, we have found great success by offering our industry leading Systems Manuals and Training Services for maintenance staff.

This preventative maintenance model combats the all-too-often reality that happens as buildings age; their performance decreases as their age increases. Our experience tells us this is a direct result of maintenance personnel not understanding the intent of the building systems, sequence of operations, and system benchmarks. ZH Commissioning PM Consultation Services are designed to provide documentation, training, and knowledge for your buildings’ maintenance staff.

What does this provide for you? On past projects, our clients report higher comfort levels for the building occupants, lower maintenance costs, and lower energy bills. These are direct results from arming maintenance staff with the proper knowledge of the systems and their intent.

ZH Commissioning offers continued support for your building’s maintenance and energy challenges. It happens often that clients will keep ZH Commissioning involved with their buildings by allowing us to track monthly energy usage and performing quarterly maintenance audits. These measures help to ensure the consistent performance of your building.

Energy Solutions

What Does “Energy Solutions” Mean?

For ZH Commissioning, Energy Solutions is defined as a common sense approach to reducing the utility costs for your building(s). By identifying past and current energy use data, comparing that to like buildings, and developing a goal to reduce costs, we develop the energy solution that is right for you.

Why Manage Energy?Energy Solutions

As energy prices continue to climb (with or without rate hikes), the costs to heat, cool, and light your building also increase. A good Energy Solution will help to lower those costs while also reducing equipment stress and run-times.

Lowering your energy costs is good business, and when done right, can be great business. Our solutions will be tailored to you and your facility, will make common as well as business sense, and be sustainable for years to come.

We aren’t here to sell you new equipment; we focus on making the systems you have work to the best of their ability.
