Mercedes-Benz Net Zero Office Concept

Net Zero Buildings = the Future of the Commercial Market

The future of the green building market rests on net zero buildings. These projects promise innovative new design – like that seen in this net zero building proposal for a Mercedes-Benz office building in Armenia – integrate a number of advanced “green” materials to maximize efficiency with renewable energy sources that generate as much energy as the project uses on an annual basis. In other words, it uses zero energy, “net”. Senior Vice President of Turner Group and President/CEO of…

Amazon Heats Building With Data Center Waste Heat

Old tech- in the form of hydronic heating– meets new in nearby data centers, creating ‘green heating’ in Amazon’s latest new buildings in Seattle, WA. The offices and work areas of the new Amazon buildings will be heated by utilizing the waste heat of a nearby data center, and Amazon’s not stopping there. Heat from the data center in the basement of the Westin Building across the street from Amazon’s proposed bio domes will be used to heat water, that will…

What is LEED? – Energy and Atmosphere

This is the fifth post in a series on the LEED green building rating system. The first post provided an Introduction to LEED, the second looked at the Sustainable Sites credit category, the third at the Location and Transportation credits, and the fourth at Water Efficiency. Energy and Atmosphere Improving energy efficiency is one of the easiest ways to save money and improve the sustainability of a building. Therefore almost a third of the points available in LEED are found in…

white roof savings

White Roof Saves $2.40/Sq. Ft. Over “Dark” Roof

In a first-of-its kind study published in the Energy and Buildings Journal earlier this year, a group of researchers compared the energy costs of buildings with white roofs against both trendy “green” roofs and conventional “black” roofs. The most shocking part of the study? White roofs saved- on average!- $2.40 per square foot over conventional roofs, and even out-performed green roofs, handily. “Owners concerned with global warming should choose white roofs,” says the study, “which are three times more effective…

Norway “Plus House” Makes More Energy Than it Uses

The Research Center on Zero Emissions Buildings (ZEB) in Trondheim, Norway has a new facility to showcase its work. Designed by architectural firm Snohetta, the ZEB Pilot House takes the “plus house” design theme further than any other existing building, producing twice the energy it consumes. The angle of the roof was carefully calculated to capture the maximum amount of solar energy year round. Instead of relying on fans and electric sensors for ventilation, the home’s architects relied on natural breezes.…

Lowe’s Smart Home Survey – Results

A new smart home study released by Lowe’s found that while Rosie the Robot is the futuristic feature consumers would want most from “The Jetsons,” more than 70 percent of smart phone users in America just wish they could control something in their home from their mobile device without getting out of bed. Lowe’s 2014 Smart Home Survey examined Americans’ attitudes and experiences with home automation, with a particular look at the most important features and top reasons for owning smart home products.…

Passive House in Qatar

Does Passive House Design Work In Extreme Heat?

A home in Barwar City, Qatar is set to be the guinea pig to answer whether Passive House design will work in the desert. Passive House (or Passivhaus in German) design relies on the mass of a building and super insulation to naturally heat and cool a building, limiting the need for heat and air conditioning. It has proven successful in cold climates, but has not yet been tested at the other extreme. The experiment involves two similar sized houses…

PEER certification evaluates power system performance

GBCI to Administer PEER Program for Power System Performance

The Green Building Certification Institute (GBCI) announced today that it will administer certification for the Performance Excellence in Electricity Renewal™ (PEER) program. PEER is the nation’s first comprehensive, consumer-centric, data-driven system for evaluating power system performance and is modeled after the U.S. Green Building Council’s LEED program for buildings. “The PEER program provides a much more complete picture of the efficiency, quality, safety, resilience and reliability of energy generation, transmission and distribution systems than is currently available. It provides actionable…
