- e-News #97: Zero Net Energy Case Studies
as a particular way to meet the goals of the 2008 California Energy Efficiency Strategic Plan. This EDR eNews features highlights from six early ZNE nonresidential projects that are described in greater detail in a full length monograph written by Edward Dean ...
- e-News #96: Commissioning for Code Compliance
design, construction, and operation. The goal of commissioning is to ensure that the design and construction of building systems meets the owner’s needs, and that building equipment is functioning optimally during occupancy. The California Commissioning Collaborative defines commissioning as ...
- e-News #95: Building Dashboards – Monitor, Measure, Manage
have been around for years, starting as humble building automation systems and developing through the years into more robust energy management control systems providing whole-building energy use information. The addition of visualization features – more commonly called dashboards – to EIS is growing in popularity because, much like an automobile’s dashboard, a great deal of information is conveyed quickly and easily. Just as drivers can see how fast a car is traveling, check how much gas remains in the tank, or see an engine light when driving, building staff have the ability to review and evaluate building operations in real time.
- e-News #94: Lighting Performance Advances
Through the past 20 years, new lighting technologies have been a major driver of increasing energy efficiency in buildings. Lighting specifiers and consumers have embraced CFLs, LEDs, and other highly efficient lighting options. How can even more efficiency savings be mined from the lighting end use?
- e-News #93: Improving Title 24 Compliance - CBECC-Com
is the open-source energy modeling program that allows architects, engineers, and energy consultants to demonstrate compliance with California’s Building Energy Efficiency Standards (Title 24, Standards) that go into effect on July 1, 2014.
The first certified version of the software was released in September 2013, with ongoing development and new features added...
- e-News #92: Evolution of LEED v4
The U.S. Green Building Council has unveiled the latest version of its Leadership in Energy and Environmental Design (LEED®) Rating System.
LEED v4 sets the bar higher for manufacturers of building materials, encouraging them to reduce environmental impacts and health hazards associated with material ingredients. Rating systems have been adapted for twenty-one additional market sectors that formerly faced barriers to LEED certification, including data centers, warehouses & distribution centers, and hospitality. LEED v4 introduces several new concepts, including IDP, BUG, LCA, EPD, and HPD. If these acronyms are not in your LEED lexicon...
- e-News #91: Title 24 2013 Update
to improve the energy performance of new and existing buildings. In addition to increased stringency, the Standards have increased in scope to include requirements for covered processes -- data centers, laboratories, kitchen exhaust systems, parking garages -- and they have increased in extent to include commissioning requirements and
additional acceptance test requirements for systems and components. A few of the many key changes to the 2013 Standards follow.
- e-News #90: Fuel Cells
. A fuel cell is a device that converts the chemical energy from a fuel – most commonly hydrogen – into electricity through a chemical reaction with oxygen or another oxidizing agent. Although many might think of fuel cells as batteries, they are not. Fuel cells require a constant source of fuel and oxygen to operate, and they can produce electricity for as long as fuel and oxygen are provided.
- e-News #89: Shining Some Light on Photovoltaics
of all building components. They make a visual statement of environmental consciousness and can substantially offset a building's use of finite resources, all while saving money on monthly utility bills. You may have seen PV systems appearing on roofs in your neighborhood or heard about how much PV prices have dropped. Is it time to consider PV for your own home or business? What's happening with solar technology and is now the right time to invest in PV?
- e-News #88: Outdoor Lighting
for safety, security, productivity, and enjoyment. Guidelines and technologies available today can help meet these lighting needs while providing good quality lighting that minimizes light pollution, conserves energy, and enhances community ambience, including the effect on wildlife and our view of the starry night sky.
- e-News #87: Benchmarking
for an organization or process, usually with the goal of motivating its improvement. Benchmarking requires the use of a common metric to allow comparison between entities, or else to a minimum standard or best-practice goal. Building energy performance is typically measured in equivalent units of consumption, over a consistent period of time, for a given unit of area
- e-News #86: Zero Net Energy Buildings
all new residential construction to be zero net energy by 2020 and all new commercial construction to be zero net energy by 2030. In order to achieve this and other goals, we must understand how to define and quantify ZNE, approach ZNE by project type, and move forward with ZNE.
- e-News #85: Radiant Heating and Cooling
are more energy efficient compared to traditional forced air systems for several reasons. But let's start at the building occupant since their comfort is one of the main reasons we have the built environment.
- e-News #84: Building Information Modeling
a 3D data-rich model of all architectural, structural, mechanical
and electrical systems in the building. The model is not only used
to design the building and document it for construction, it's also
used as the primary tool to create and coordinate design
- e-News #83: Supermarket Refrigeration
have the second highest energy consumption of major building types in California, with electricity representing over 80% of this, and with energy-intensive refrigeration consuming the greatest fraction of electricity.
