Reducing Energy Consumption with High-Temperature Heating and Ventilation

The Construction Specifier, May 2016, by Marc Braun.
http://www.constructionspecifier.com/reducing-energy-consumption-with-high-temperature-heating-and-ventilation/

"The Department of Energy published a study, “Field Demonstration of High-efficiency Gas Heaters,” where it discussed how high-temperature heating and ventilation (HTHV) direct gas-fired heaters dramatically reduce energy consumption when replacing unit heaters in warehouses and other high-bay buildings. These direct-fired technologies—often referred to as ‘make-up air heaters’—have been widely adopted as high-efficiency ventilation units. The surprising thing is specialized versions of these products can accomplish high-efficiency space-heating when ventilation is not required, such as during unoccupied times."

"High-performance lighting designs aim to satisfy occupants while they slash energy use."

Replacing a Steam Boiler

"When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly. A hydronic system uses sensible heat while a steam system uses both sensible and latent heat. Sensible heat can be measured with a thermometer while latent heat causes a change of state and cannot be measured accurately with a thermometer. The following are some of the steps I take when designing a replacement steam system."

What Matters When Purchasing a Small Wind Turbine?

Solar Today, Spring 2016, by Mick Sagrillo.
http://solartoday.org/2016/05/what-matters-when-purchasing-a-small-wind-turbine/

"What makes a manufacturer worth considering? With the plethora of small wind web sites out there, it’s might seem daunting to try to ferret out the wheat from the chaff, who is a legitimate small wind manufacturer and who is a huckster. Actually, it is simpler than it appears. Remember the discussion about turbine certification? (ST Winter 2015/2016) This is your screen. Any manufacturer not listed with a certified turbine should not be considered, period. No matter what they promise or how much they plead. Do you want to be someone’s beta test site or do you want a working wind system for decades?"

Energy Efficiency in Commercial Tenant Spaces - A Feasibility Study

U.S. Department of Energy, Apr. 2016.
http://energy.gov/eere/buildings/downloads/energy-efficiency-separate-tenant-spaces-feasibility-study

"While commercial building owners generally have control over building systems and operations, tenants play a critical role in achieving lasting reductions in energy intensity. In recognition of this collaborative role, the Department of Energy has studied the feasibility of improving energy efficiency in tenant spaces. This study finds significant potential to improve energy efficiency during the design and construction of tenant spaces and describes several possible steps to encourage owners and tenants to improve the efficiency of those spaces."

ASHRAE Research Outlines Measures to Reach Toward Net Zero Energy

Engineered Systems, Apr. 26, 2016.
http://www.esmagazine.com/articles/97706-ashrae-research-outlines-measures-to-reach-toward-net-zero-energy

"Thirty specific energy savings measures across all building types and climate zones resulted in cutting energy use by nearly half, according to results of newly approved research funded by ASHRAE."

ASHRAE Revises Commissioning Certification to Meet DOE Guidelines

Engineered Systems, May 3, 2016.
http://www.esmagazine.com/articles/97724-ashrae-revises-commissioning-certification-to-meet-doe-guidelines

"Due to take effect Sept. 15, 2016, ASHRAE’s commissioning certification program will validate competency against the Better Buildings Workforce Guidelines scheme requirements for the Building Commissioning Professional set forth by the National Institute of Building Sciences (NIBS) Commercial Workforce Credentialing Council (CWCC). The goal is to achieve U.S. Department of Energy (DOE) recognition by the summer of 2017 of services provided by these certificants. The ASHRAE certification will be known as the Building Commissioning Professional (BCxP)."

A Comprehensive Look at the Intelligent Building

Consulting-Specifying Engineer, Apr. 2016, by Steve Brown, Kurt Karnatz, and Rob Knight.
https://www.csemag.com/single-article/a-comprehensive-look-at-the-intelligent-building/66f3fdc8eabebe681dbabd1dff01d68f.html

"Technology is changing what’s possible for buildings. With the advent of smart building technology, heating, cooling, electrical, lighting, fire/life safety, and other systems need monitoring and intercommunication for optimized efficiency and operation."

Smart Buildings Demand A Smarter Approach To O&M

Engineered Systems, Apr. 2016, by Robert S. Novak.
http://www.esmagazine.com/articles/97666-smart-buildings-demand-a-smarter-appoach-to-om

"In the beginning, the goal is to enable the operations and maintenance staff to work with the system to give it the best chance to perform as designed. Later, the vision is a culture of continuous improvement that can withstand changes in technology and personnel. In between? Plenty of opportunity for thoughtful operations and standardized routines."

Energy Department Invests $14 Million to Increase Energy Efficiency of Nation’s Homes and Buildings

U.S. Department of Energy, May 9, 2016.
http://energy.gov/eere/articles/energy-department-invests-14-million-increase-energy-efficiency-nation-s-homes-and

"As part of the Administration’s effort to cut energy waste in the nation’s buildings and double energy productivity by 2030, the Energy Department today announced $14 million to dramatically increase the efficiency of our nation’s homes and buildings. These projects will cut energy costs for thousands of American families and businesses, while leading to greater demand for new building products and technologies, many of which can be produced in the U.S."  Funding distributed through the DOE Commercial Buildings Integration Program (6 projects), and the DOE Building America Program (8 projects).
