"Potable Water distributed within a building should be colorless, tasteless, odorless, and aesthetically acceptable to the occupants. It should contain no pathogenic organisms, biological forms, or concentrations of chemicals or metals which may be harmful to human health. In addition, the water should not be corrosive to or leave deposits on the distribution system through which it passes or may be retained."
Corrosive Water can electrochemically destroy the potable water system of a building. Heated, high hardness water can produce heavy scale deposits in a system and significantly reduce its carrying capacity. Corrosion also adversely affects taste, color, and aesthetic appeal of water and can increase the concentration of toxic metals. Only when the problem of corrosion in potable water systems of buildings has been properly identified and the factors affecting its occurrence carefully analyzed is it possible to select the most advantageous method for correcting the problem."

Canada is in the envious situation of having one-fifth of the world's fresh water supply. Canadian water usage per capita is the second highest in the world at approximately 326 litres per day.
"The Guide to Greening Government Operations was signed by all federal Ministers, committing federal government departments to lower the environmental impacts of their operations, policies and programs. The Commissioner of the Environment and Sustainable Development will audit the departmental performance."
"6.7 The Federal Buildings Initiative
The Federal Building Initiative (FBI) is a comprehensive program created by Natural Resources Canada to provide federal facility managers with an opportunity to realize the benefits of improved energy efficiency. The program also assists in the incorporation of water saving initiatives when considered in conjunction with energy refits."
"6.8 Reducing Water Use
Changes in staffing arrangements often require renovations to existing buildings, or sometimes even the construction of a new facility. Most renovations and new construction projects can provide opportunities to reduce water consumption."
Consultant's report finds savings of individual meters in buildings can trigger energy savings ranging from 27 to 34 per cent.
"As for how Navigant came to such conclusions, it relied on data from Natural Resources Canada, Statistics Canada’s 2007 Census data, and hundreds of samples of monthly electricity consumption data from customers of EnerCare that had already switched from bulk billing to sub-metered billing."
Addressing our nation’s existing and future building inventory presents one of the greatest opportunities in the United States for reducing energy consumption and greenhouse gas emissions, according to Ingersoll Rand Chairman and Chief Executive...
“Making our current and future building infrastructure more intelligent and efficient provides the most immediate and tangible return on investment for business and government,” Lamach said in his remarks to the group. “Doing so allows businesses to manage the rising costs of energy. It gives them more capital to invest in growth, innovate and create new jobs.”
Recommissioning is a holistic, systematic process applied to existing buildings to identify and implement operational and maintenance improvements, and to ensure continued performance over time. ... Recommissioning optimizes how equipment and systems operate as well as how systems function together. .... Recommissioning is not a substitute for major repair work; in fact, repairing major problems must be done prior to recommissioning."
"Impact on Owners and Operators
A direct impact of recommissioning for building owners and operators is the reduction of energy and demand costs due to improved building operation. A 1996 U.S. study of the cost effectiveness of recommissioning 44 existing buildings revealed attractive paybacks, even when the estimates were based solely on energy cost savings. Recommissioning proved to have modest project costs of between $10,000 and $80,000, resulting in whole-building energy savings of between 5 and 15 percent."

"Even if you don’t believe or care about the ozone hole and skin cancer, this loophole is going to cost people more money when they’re being promised savings."
"This whole dry-ship R-22 unit game has been a dirty little secret of the EPA and the HVAC industry with plenty of folks in the industry and government willing to justify jumping through the loophole."
The construction and operation of buildings consumes over a third of the world’s energy consumption, and 40% of all the mined resources.
"In more practical terms, this means that a sustainable building cannot, in construction, operation, or disposal:
-consume materials unless they can be easily and harmlessly extracted, used, and returned to nature,
-consume non-renewable energy,
-destroy natural habitat, bio-diversity, or bio-mass, or
-release pollutants of a type or quantity that cannot be harmlessly broken down by natural systems.
These are very difficult criteria to meet, and in fact require all aspects of human activity to be changed to meet them. For example, until steel is recycled in a non-polluting manner using renewable energy sources, no steel of any type (including nails or screws) can be included in a truly sustainable building. Clearly we are very far from producing even a single truly sustainable building in the industrialized world. However, to move toward these goals is both possible and practical."
"For the design, construction and operation of a facility, there is an especially important interface between the indoor and outdoor environments, that of the building envelope. The building envelope is comprised of the outer elements of a building—foundations, walls, roof, windows, doors and floors. The prime functions of the building envelope are to provide shelter, security, solar and thermal control, moisture control, indoor air quality control, access to daylight, and views to outside, fire resistance, acoustics, cost effectiveness and aesthetics."

"Our climate is very cold and moist, for this reason the indoor grey water garden is designed to move water though it quickly rather than to act as a holding cell. The garden is isolated on the west side of the house, along with a bathroom, rather than across the front of the house. This will make it easy to control the humidity levels of that part of the house, whilst allowing the rest of the house to be opened up with a 2 level high ceiling and loft area. The second floor will sit about 8 feet behind the first on a secondary rock shelf that was carved out 9' 6" higher than the bottom platform."
A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.
Put into context, the cost of reducing carbon dioxide emissions is currently estimated to be between 0.2 and 2.5 per cent of GDP in the year 2030, which is equivalent to roughly USD $200 to $2000 billion.
Solar radiation management (SRM) looks to induce the effects similar to those observed after volcanic eruptions; however, the authors state that it is not a preferred strategy and that such a claim could only be made after the thorough investigation of the implications, risks and costs associated with these issues.
"In the beginning, the Master Economist created the Economy. He created businesses large and small, consumers, governments with their regulation, and financial institutions of all types. And the Master Economist declared that the economy should grow. And it did grow, but only for a while. Then it stalled. Then He declared that stimulus of various types should fix it, and it did, for a while. Then He declared that if humans would just wait for a while, it would fix itself, but it wouldn’t."
I would like to offer a few thoughts about Dan’s recent post where he states;
“The economic formulas assume that people want their children and grandchildren to be as well off as they are, no better and no worse. But people actually want the future to be better than the present, and they’re willing to make sacrifices for this to happen. The economists need to wake up to that fact.”

"Studies have proven that outdoor air ventilation creates a healthful work environment. However, as these intake rates increase, so does the size, cost, and operating expense of the heating, ventilation, and air conditioning (HVAC) system. ..."
"During the ventilation process, large amounts of energy are wasted as HVAC systems replace indoor air with fresh outdoor air multiple times per day. ..."
"To address this challenge, one option for fms is a site recovered energy technology such as energy recovery ventilation (ERV). Site recovered energy is any energy recovered on-site and reused to reduce the demand for more energy...."
"Optimizing a building’s energy consumption requires an approach that allows devices and systems to function together in an efficient and cost-effective way to meet occupant requirements and expectations. This approach is called “commissioning” for new buildings and “recommissioning” for existing buildings. When it is applied in a permanent manner to an existing building, it is called “ongoing commissioning”."

Envitrum has developed a product that's more environmentally friendly than masonry.
"Marchelli and Renuka Prabhaker, 37, a fellow graduate student, think they’ve come up with a way to recycle more glass, regardless of color or contaminants. Their nascent Seattle-based company Envitrum (Latin for “out of glass”) has developed a manufacturing process that converts crushed 100 percent post-consumer glass into a material called VitroBricks. The process isn’t that different from the way traditional masonry bricks are made, except that the heat needed to fire the form-pressed glass is about 60 percent less than for masonry, although Prabhaker notes that the heating schedule for VitroBricks could have as many as 10 temperature phases."
Moisture is one of the most important agents leading to building enclosure deterioration.
Siting, building shape, and surface rainwater control rarely provide complete rain control in rainy climates (although deep, wrap around porches may eliminate the need for rain control under them). Hence, some strategy to deal with the rainwater that penetrates the surface of the wall must be employed. There are three fundamental rain control strategies available to the designer . In order of historical priority, they are:
Storage (storage or mass walls),Exclusion (perfect barrier walls), andDrainage (drained and screened walls)."
Water For People helps people in developing countries improve their quality of life by supporting the development of locally sustainable drinking water resources, sanitation facilities and hygiene education programs.
"A year of Play Pumps in the fieldBy the time of Water For People’s roll-out in 2010, concerns about Play Pumps had been documented across the development sector in Africa. Water For People welcomed the chance to address these challenges with innovations in functionality and safety, and in approaches to management and maintenance. All of these have been pursued in good faith over the past year.
Following are the highlights of that effort:
A Play Pump cannot provide water for an entire community....
The Play Pump storage tank was not user-friendly."
