"Submetering products and services sales are expected to double by the end of the decade. Commercial tenants seeking to boost efficiency turn to submetering as a way to understand baseline energy use, and to provide verifiable data."

Controls: 8 Ways Integration Helps Green Buildings

Building Operating Management, June 2014, by Jim Sinopoli.
http://www.facilitiesnet.com/buildingautomation/article/System-Integration-Can-Help-Meet-Green-Energy-Efficiency-Goals--15014

"Building owners seeking a green building certification or energy rating for a new building or a renovation generally push the idea of system integration to the background. To some extent this is understandable. They're probably familiar with integration involving the fire alarm, smoke control, elevators, and access control — essentially life safety integration. But they may not be aware of the functional benefits of integrating other systems and the opportunities to analyze an integrated database of system data points."

Designing Masonry Buildings to the 2012 Energy Code

The Construction Specifier, June 2014, by Steven Fechino.

"Change is coming to the building industry, driven by a need for far more efficient energy use in the built environment. Masonry has many qualities that make it an ideal building material for energy-efficient construction, including its thermal mass, sustainability, high level of availability, and design flexibility. A combination of new building materials, a better understanding of building dynamics, and improved design software is making it possible for designers to create masonry buildings that meet the new energy codes; skilled masons will be key to making these energy-efficient buildings a reality."

Being Radiant: Planning In-Slab Hydronic Heating and Cooling

The Construction Specifier, June 2014, by Ryan Westlund.

"Radiant systems are ideally suited to a broad range of commercial applications and achieve best results when combined with other energy-efficient solutions in tight building structures. While radiant heating-only systems have a long history in conditioning both commercial and residential structures, radiant cooling is fairly new to North America. Early adopters of these systems were located primarily in arid regions. Mainstream acceptance required the development of more advanced controls, coupled with compelling evidence of reduced energy consumption for the built environment."

Designing for Comfort & IAQ: Air Distribution per ASHRAE 55 and 62.1

The Construction Specifier, June 2014, by Jim Aswegan and David Pich.
http://www.constructionspecifier.com/masterformat/designing-for-comfort-iaq-air-distribution-per-ashrae-55-and-62-1/

"The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) 55-2013, Thermal Environmental Conditions for Human Occupancy, and ASHRAE 62.1-2013, Ventilation for Acceptable Indoor Air Quality, provide designers with the guidance to optimize health and comfort in building spaces. Many codes, along with the U.S. Green Building Council’s (USGBC’s) Leadership in Energy and Environmental Design (LEED) 2009 program, require compliance with these ASHRAE Standards."

ESCOs Offer Energy Efficiency Without Inflated Upfront Costs

"Energy Services Companies help buildings affordably trim energy usage."

Heat Pumps Designed to Save Energy

Air Conditioning, Heating, Refrigeration News, May 26, 2014, by Joanna R. Turpin.
http://www.achrnews.com/articles/126690-heat-pumps-designed-to-save-energy

"The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well, thanks to the growing demand from building owners and managers, who are looking for ways to save energy."

How to Design & Control Waterside Economizers

ASHRAE Journal, Jun 2014, by Steven T. Taylor.

"ASHRAE/IES Standard 90.1 requires either airside economizers or waterside economizers for most cooling system applications. Air economizers are more common and almost always more energy efficient. But there are some applications where water economizers are preferred."

Hydronic Heat Recovery in Health Care

ASHRAE Journal, Jun 2014, by Jeremy McClanathan.

"Swedish Issaquah, a 350,000 ft2 (32 500 m2) hospital located in Issaquah, Wash., uses a hydronic heat recovery system to achieve a 50% energy savings compared to an average hospital in the Pacific Northwest."
