"Most North Americans live in auto-dependent suburbs requiring high-carbon lifestyles. While cities and the walkable, bikable, compact, low-carbon living they facilitate are seeing a welcome resurgence in popularity, postwar suburbs, in particular, are facing unprecedented challenges. These challenges include increases in poverty, aging populations, more frequent flooding, and the cost of transportation, energy, and infrastructure maintenance, as well as declines in affordability, the number of jobs, social capital, public health, and environmental quality."

"Cold temperatures and disruptive precipitation create problems every year. When it comes to heating spaces, the challenge tends to be how to do
it effectively and efficiently. ...Variable refrigerant flow (VRF) makes the most of the square footage and budget while offering energy-efficient and reliable technology providing superior occupant comfort. It achieves success by dividing a building’s interior into zones, each of which can be operated separately."

"Whole home retrofits aim to address the biggest residential energy issues. Their number has grown in recent years along with contractor and program experience in delivering successful retrofits. However the demand for these programs and their participation rates have not grown as much, and many of them fail to capture the full range of available savings. This report explores the challenges faced by home retrofit programs and describes the best strategies for improving project-level realization rates."

"As LED illumination technology improves in efficiency, reliability, and quality, building owners become interested in cost-effective ways to apply LED lighting in their facilities. In many cases, retrofitting existing fluorescent or incandescent luminaires will be an attractive alternative to wholesale fixture replacement. This article explores the effects of some of the applicable codes on LED retrofit projects."

ASHRAE Journal, Aug. 2016, by Dylan Connelly and Laura Fedoruk. (Article Summary only.)
"DPR Construction’s retrofitted San Francisco headquarters building achieved approximately 20% net positive energy its first year of operation using efficient systems including HVAC, electrical and PV. And, in late 2015, it was certified as a net zero energy building. The office building demonstrates the capabilities of integrated, innovative, and replicable design. And, it proves that sustainable buildings can reduce energy use and improve indoor environmental conditions, while being cost effective. It has become a hub for learning and collaborating on many sustainably minded design projects."

"Window replacement isn’t cheap, but neither are existing windows that are out of date and inefficient. The opportunity to upgrade comes around infrequently – possibly as part of a broader energy conservation plan funded by one financial package – so owners must maximize their return."

"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."

"Replacing boilers for health care facilities provide many benefits to central utility plant operation; the newer boilers are more energy efficient, more sustainable, and more fuel-efficient than older boilers."
