Proposals for Green Building Standard to Keep Water from ‘Going Down the Drain’ - Sustainable Plant

Proposed measures to improve water efficiency of high-performance, non-low-rise residential buildings include limitations on full-flush volume for toilets and use of municipal reclaimed water for irrigation.

 

"Measures to improve water efficiency, including limitations on full-flush volume for toilets and use of municipal reclaimed water for irrigation, are being proposed for ANSI/ASHRAE/USGBC/IES Standard 189.1-2011, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings. ..."

 

"The addendum would limit the full-flush volume for all toilets to 1.28 gal per flush and limit kitchen faucet capacity to 1.8 gpm ..."

 

"Proposed addendum v also would set limits on the use of municipal reclaimed water for irrigation. Municipal reclaimed water is highly treated, usually to drinking water standards, and often in short supply. Furthermore, the growing use of municipal reclaimed water for groundwater recharge of potable water supplies increases its value. ..."

 

'“It is unreasonable to allow the unfettered use of reclaimed water, considered a precious resource, as a means to save energy when there are more viable alternatives,” Pape said. “Therefore, the use of municipal reclaimed water would be prohibited for roof-cooling applications and for permanent irrigation of vegetated roofs using either in-ground or above-ground irrigation systems. There are many other alternative water sources that can be used for this puprpose, including graywater, condensate recovery, rainwater and cooling tower discharge.”'

Living Walls Transform Green InteriorsDesignBuild Source Canada

Living Walls Transform Green InteriorsDesignBuild Source Canada | Green Building Design - Architecture & Engineering | Scoop.it
The incorporation of interior greenery has grown to the point where it now even takes up indoor wall spaces.

 

"A new trend sees ‘bio-walls’ offering bring new life into conventional spaces. According to former University of Guelph researcher Dr. Alan Darlington, the incorporation of these green walls are drastically increasingly Indoor Environmental Quality (IEQ) passively, without energy reliance."

 

“We’re getting rid of 60 to 70 per cent of the pollutants in the air after a single pass through the filtration system,” he said. “It means less fresh outdoor air has to be brought in to maintain air quality and that significantly reduces the energy required to heat or cool that air. It’s a really beautiful technology.”

GSA Report on Green Building Ratings Systems Expected Soon, As Use of LEED in Federal Buildings Doubles | Meg Waltner's Blog | Switchboard, from NRDC

The number of LEED-certified federal building projects is projected to more than double this year: 821 projects received certification in the first 8 months of 2012 alone, up from 544 projects total in 2011, as reported in the Federal Times...

 

"This increase in LEED certified federal buildings comes in the midst of a full-fledged attack against the use of LEED from the timber and chemical industries, who have been lobbying against the use of the LEED rating system in federal buildings (see this letter to GSA as an example)."

Bus Depot, Warehouse Raise Green Building Bar

Bus Depot, Warehouse Raise Green Building Bar | Green Building Design - Architecture & Engineering | Scoop.it
Two industrial projects in Queensland and New South Wales have raised the bar in green building and construction for warehouses and industrial facilities throughout Australia.

 

"... the bus depot has been recognised for a number of initiatives, including light-filled offices, breakout areas and workshops, ‘excellent’ passive design and natural ventilation which makes the most of Queensland’s climate.

 

[also]... on-site water collection, re-use and management strategy that treats storm water through a biofiltration system which then provides most of the depot’s non-potable water demand."

TULSA, Okla.: Tulsa’s Guthrie Green ‘Central Park’ by SWA Group Catalyzes Urban Regeneration in Growing Oklahoma Town | Business Wire | Rock Hill Herald Online | Green Building Design - Architecture & Engineering | Scoop.it

Former truck facility reborn as 2.7-acre park and music concourse with innovative geotherm energy to heat/cool adjacent arts buildings

 

"Early in the design, the team conceived of installing a ground-source heat pump system under the park. Consisting of 120 wells drilled to 500 feet depth, the "geo-exchange" system generates 600 tons (7.2 million BTUs/hour) of heating/cooling distributed via underground pipes to serve 120,000 square feet of nearby non-profit users as well as Guthrie Green’s cafe pavilion and bathrooms. Photovoltaic panels on the pavilion roof supply power for the heat pump system. The system enables 60% reduction in energy demand, with investment payback in five to seven years. The concept won the project a $2.5 million ARRA Stimulus Grant and other state/local funding."

Geothermal Energy Advocates Hope Systems Get a Second Look

Geothermal Energy Advocates Hope Systems Get a Second Look | Green Building Design - Architecture & Engineering | Scoop.it
Digging geothermal wells can be expensive and difficult, and the systems have been slow to catch on in New York City, but the benefits may eventually outweigh the costs.

 

"Advocates for geothermal energy say that the path of destruction cut by Hurricane Sandy, which unearthed fuel tanks, ravaged cooling towers and battered air-conditioners, has already persuaded some building owners to switch to geothermal systems that use underground pipes to harness the earth’s energy for heating and cooling buildings. "

 

"Installing a geothermal system can significantly reduce a building’s carbon footprint, and over the last decade, the number of geothermal heat pump systems in the city has grown steadily. More geothermal systems are installed in New York, New Jersey and Pennsylvania than anywhere else in the United States. "

Energy efficiency is at the heart of changes that will be incorporated into structures of the future

By Scott Simpson, Vancouver Sun October 27, 2012

 

"Retrofits are crucial.


One of Hood's main assignments is overseeing the redevelopment of existing buildings. More often than not, that means uncovering, through energy audits, glaring examples of waste - air leaks, inadequate insulation, inefficient heating and ventilation systems.

 

"We are involved in residential projects where we can achieve 80-per-cent reduction in energy use .... These are tried and true technologies around good building enclosures and high-performance mechanical systems such as heat pump technology."

 

"On the commercial side, a lot of the audits we do for energy we're seeing 30-to 50-per-cent reduction in energy use in ways that are cost-effective. The payback is five to eight years."

Economics of energy efficiency: Beyond ROI

Economics of energy efficiency: Beyond ROI | Green Building Design - Architecture & Engineering | Scoop.it

Engineers and building owners often focus on payback periods and return on investment as economic decision-making thresholds for energy efficiency investments.

Back in the day, HVAC systems were designed to be stout, longevity was the main focus, and concepts such as operating costs and efficiencies were virtually non-existent. The driving force was purely “How much will it cost and will it last?” Interest rates and return on investments were left to the bankers and stockbrokers.


"A more sophisticated approach is present worth analysis, which establishes a present time value of all future cash flow by discounting the costs. A typical time frame used for this procedure is 20 years. ..."

 

"Data considered as input includes the future costs of energy, future maintenance costs, replacement costs, life of the product, and future interest rates. There are some pitfalls: prediction of future energy cost is a guessing game, just like predicting stock prices. Two factors, weather and people, are not 100% predictable. Planned maintenance cost can be somewhat consistent, but one catastrophic failure will ruin the budget. In the end, the analysis produces a lifecycle value in today’s dollars. This is then compared to similar investment analyses to select the most reasonable investment. The process can be intense and the projected outcome is always subject to scrutiny."
