Building Science

Building science consists of overall knowledge of the building envelope, HVAC air flow, thermal & air barriers, air leakage, duct systems, carbon monoxide, carbon dioxide, pressures, water intrusion, ventilation, air pressures, flue drafts, foundations, post & beam & electrical systems. On a larger scale we provide data logging to collect data on electrical, temperatures, amps, watts and loads. Many experts guess or place an average on temperatures, humidity, loads, amps, watts and run time. We do not guess! We can place dozen's of loggers on electrical, mechanical, HVAC, lighting to record operational use. Example: Large warehouse freezers, are they performing efficiently?  Office HVAC systems? Gas fired equipment? Lighting? Once data has been gathered and reports are developed we can then determine the best solution to lower your overall utility usage. Data rooms or clean rooms need to be controlled for temperatures and humidity. This revolves around HVAC and mechanical. Most of the time these rooms remain vacate with no personal. How do you know 24/7 what the environment is?    

Oregon Inspections

CZ Services provides quality professional home & business inspections. Looking to purchase or lease a home or business, let us conduct our detailed inspection for you. We stay competitive and we do offer more! 

Through the years we have spent a great deal of time in class rooms to sharpen our skills. This also has earned us additional certifications to better serve our clients. Our inspections revolves around years of experience in residential & commercial structures. We have spent more than 35 years installing electrical, HVAC, duct systems, lighting, insulation, air sealing, crawl spaces, ventilation. For the past ten years we have spent time improving structures for energy usage. This time also refers to testing and as a proctor training businesses. We are the only licensed & certified general contractor in Oregon to provide inspections & energy assessments.  

Energy Management

CZ has a passion for reducing energy usage & inspections to protect your investment. Our focus has always been devoted in researching the latest technology to pass on to our clients. CZ is a Sustainable & Environmental Business leader serving our clients. For nearly a decade we have implemented the installation of LED lighting for commercial businesses. Serving hundreds of clients with a reduction on average of 33% savings on energy usage. 


CZ provides a wide range of services to Oregon Residents & businesses. With over 35 years experience and many certifications relating to building science, health & safety. Our focus has always been to analyze buildings for energy usage, reduce energy usage, health & safety and environmental issues. A data logger is a electronic device that is attached to electrical motor, HVAC system, gas line, water line to measure how long a electrical motor is on, watts, amps, voltage, or how much energy is being used. A data logger can also be mounted in a room or duct system to measure temperatures, air flow etc. Data loggers are an accurate way to measure and record data.  

Data Logging involves inspecting structures from the exterior to the interior. From the roof to the foundation to mechanical, electrical, plumbing and structural. Data collecting also involves testing and recording operational HVAC systems, electrical devices, temperatures, moisture, gas & oil fired equipment, equipment condition, etc. We install electronics to monitor and record energy usage and accurately measure usage. If you need to know exactly how much energy a electrical piece of equipment is using, we can answer that question. Watts, Amps & load. For one day or one month we can monitor electrical equipment from 5 amps to 200 amps. Then provide a spread sheet report. With inspections or energy audits data collecting is the first step.Example: Large warehouse freezers, are they performing efficiently?  Office HVAC systems? Gas fired equipment? Lighting? Once data has been gathered and reports are developed we can then determine the best solution to lower your overall utility usage. Data rooms or clean rooms need to be controlled for temperatures and humidity. This revolves around HVAC and mechanical. Most of the time these rooms remain vacate with no personal. How do you know 24/7 what the environment is? 

Inspections visual oversight of the building envelope & components. We visually inspect the exterior and interior structure, roof, walls, plumbing, electrical, windows, floors, walls, drainage, doors, HVAC, water run off, foundation, insulation, etc. Our inspection includes testing plumbing, HVAC, pumps, motors, lighting, etc. Our inspection may include additional services involving testing and measuring the air flow in the duct system, flue draft testing of gas fired equipment, thermal imaging scans for air leakage and over heated electrical, building pressure testing, etc. We provide the standard "SOP" inspection and perhaps include an energy assessment that provides efficiency or non efficient of the building envelope. Many local governments are requiring energy assessments on homes being sold. However these assessments do not include health & safety for some reason.  

HVAC Duct Systems: The duct system is the heart of heating and cooling. Depending on the size of the air handler and the duct system will determine the efficiency and comfort zone of the building envelope. We find in many cases the duct system was either not balance correctly or the duct system was undersized. All air handlers display the cfm  from the data plate on the system. We take measurements to confirm air flow cfm at the system plenum and at each register. Then compare our readings with manufacture data sheet.

In addition to inspections and data collecting we conduct a valuable service very few people know about. CAZ- combustion appliance zone. With gas or oil fired equipment it is very important to test the efficiency of equipment and also test the flue draft CO and spillage. This applies to both residential and commercial equipment. This also leads us to another important service.

Building pressures. Pressures greatly effect the operation of gas / oil fired equipment. Pressures also involves fresh air exchanges in volume of air. All buildings must have fresh air exchanging. This is also a major factor in chemical storage and air that contains dirt, dust and germs. The cleaner air the better!

Air Quality: With new technology we are able to test structures for radon, CO & CO2. Utilizing scientific meters and devices we can evaluate air quality and receive data the same day. More & more people are becoming more concerned about the air they breath at work and home.  

Radon Testing: Radon testing in Oregon should be done on every home and business. Oregon has very high levels of radon within its region. I should know, our house had very high levels and did cause lung cancer. We provide the latest technology in radon testing. A 48 hour test using electronic equipment will provide you with a printed report & accurate results. 

Medical Facility Pressure Testing: I believe all medical facilities "mainly" hospitals rely on negative pressures indoors. Because of air born partials "germs" are widely present. People go to medical care facilities either for injury's or sickness. Why you are sitting in a waiting room you could be breathing everyone's germs. In operating rooms the last thing they need is contamination. So annually facilities should be inspected. We have been conducting pressure testing for many years. We can test room by room or the whole structure.

Commercial LED Lighting: For nearly a decade we have helped commercial business owners reduce energy usage. The most common way has been with LED lighting upgrades. Hundreds of businesses has benefited and reduce energy usage by 30% or more with lighting upgrades.
