New Refrigerant Regulations Impact HVAC Systems
Rising energy costs and a movement toward sustainability are driving changes in the commercial HVAC market. As design engineers, building owners and mechanical contractors focus on increasing comfort and maintaining air quality while reducing overall energy consumption, the technology and components of HVAC systems are constantly being reevaluated.
Two heating and cooling methods often compared in terms of energy consumption and system performance are hydronic systems and variable refrigerant flow (VRF) systems.
Hydronic systems provide water-based heating and cooling through pipes, ductwork and other components such as pumps, drives, controls, heat exchangers and valves. VRF systems use refrigerant as the primary heating/cooling medium, comprised of a main compressor unit connected through refrigerant lines to multiple indoor cassette units that can be individually controlled.
Updated refrigerant safety guidelines

IAPMO Holds Technical Committee Meetings for Development of the 2018 USPSHTC and USEHC
The International Association of Plumbing and Mechanical Officials (IAPMO) this month concluded Technical Committee meetings toward the ANSI-accredited consensus development of the 2018 editions of the Uniform Solar Energy and Hydronics Code® (USEHC) and Uniform Swimming Pool, Spa and Hot Tub Code® (USPSHTC). The USPSHTC meeting was held via teleconference and the USEHC meeting was held at IAPMO's World Headquarters West building in Ontario, Calif.
The technical committees, consisting of a broad coalition of industry experts — installers, inspection officials, contractors, engineers, and manufacturers — considered public comments to amend the USEHC and USPSHTC in advance of the release of the 2018 editions. Their actions to accept, modify, or reject these comments will be electronically balloted to the technical committees for formal voting between Nov. 15 and Dec. 4. The results of these votes will be published in the Report on Comments to be published for review in March 2018.

At the Request of Industry, U.S. Senate Committee Supports WaterSense
The U.S. Senate, at the urging of the plumbing industry and its partners, via language in a Department of the Interior appropriations bill for the fiscal year ending Sept. 30, 2018, expresses strong support for the continued operation and complete funding of the U.S. Environmental Protection Agency's (EPA) WaterSense consumer product labeling program.
"The Committee rejects the proposed elimination of the WaterSense program, and provides not less than the fiscal year 2017 level," per the bill, introduced recently by the Appropriations Committee.
HeatSmart Mass Installers Request for Proposals
The Massachusetts Clean Energy Center (MassCEC) and the Department of Energy Resources (DOER) are seeking proposals from installers of clean heating and cooling technologies who are interested in participating in the HeatSmart Mass pilot with expertise in some or all of the following residential technologies: air-source heat pumps, ground-source heat pumps, central biomass heating, and solar hot water.
HeatSmart Mass is a community-based outreach and education program that will encourage clean heating and cooling technologies. The pilot aims to help drive down the installation cost and increase deployment of residential and small-scale commercial clean heating and cooling installations through a group purchasing model.
GSA, DOE Issue RFI for Innovative Building Technologies to Improve Federal and Commercial Building Performance
The U.S. General Services Administration (GSA) and U.S. Department of Energy (DOE) issued a joint Request for Information (RFI) for next-generation building technologies that have the potential to improve the operational efficiency of federal and commercial buildings, and provide a solid return on investment.
The RFI invites technology manufacturers and industry to submit information on technologies that are nearly ready for commercial use, or in the early stages of commercial application, for evaluation through GSA Proving Ground (GPG) program and DOE's High Impact Technology Innovation Catalyst (HIT Catalyst). Selected technologies will be matched with federally owned buildings and/or commercial buildings, for third-party measurement and verification. Project results are intended to help validate the technical and operational characteristics of the technology and its potential for future deployment.
Have You Watched the BEST Tutorial?
The Building Efficiency System Tool™ (BEST) was created to better inform prospective builders, consulting engineers, and design-build professionals about their selection options for HVAC systems during the early design process, and to make it free, fast, and easy to understand. To learn more, watch the overview.
The BEST uses the Building Energy Efficiency Ratio (BEER), which takes certified AHRI data, manufacturers' published performance data at multiple performance points, as-applied correction factors, performance curves for components, pipe and duct required in a typical system, and combines them to bridge the gap between certified equipment efficiencies and real-world building system efficiencies. To learn how to put this powerful tool to use for your business, start by watching the tutorial.
NABCEP Adds Solar Heating System Inspector and PV System Inspector Certifications to its Industry-Leading Programs
The North American Board of Certified Energy Practitioners (NABCEP) announced the addition of Solar Heating System Inspector (SHSI) and Photovoltaic System Inspector (PVSI) Certifications to its industry-leading programs. Unlike many of NABCEP's other certifications, there are no specific pre-requisites for taking a NABCEP PV or Solar Heating System Inspector Exam, and the test can be taken online from anywhere that has a stable internet connection.
Inspectors play a critical role in ensuring quality renewable energy installations. These new credentials are meant to provide a mechanism for inspection professionals to demonstrate their knowledge of PV and Solar Heating systems.
NABCEP PV and Solar Heating System Inspector certifications are intended for individuals performing system inspections for Authorities Having Jurisdiction (AHJ's), utilities, incentive programs, investors, and others involved in quality assurance and code compliance of PV and Solar Heating system installations.
