Efficiency

Efficiency is a comparison of the amount of energy used compared to the amount of output produced. In the built environment, this means using the least amount of energy (electricity, natural gas, etc.) to operate a facility appropriately. Steps that can help a building run efficiently include: ensuring there are no air leaks, using sensors or timers to ensure the building isn’t operating when vacant, and using energy-efficient equipment.

  • Water Efficiency

    Buildings are significant users of the Earth’s potable water supply.  The goal of a responsible building operator should be to encourage a smarter use of water, both inside and outside the facility.  Indoor water use reduction is typically achieved through efficient plumbing fixtures, fittings, appliances and process equipment used to heat and cool the building; outdoor water use reduction efforts should focus on water-wise landscaping.

  • Water Consumption

    Between 1950 and 2000, the U.S. population nearly doubled. However, in that same period, public demand for water more than tripled. Americans now use an average of 100 gallons of water each day—enough to fill 1,600 drinking glasses. Source: EPA WaterSense, Why Water Efficiency?

  • Improved IEQ Benefits

    Improvements in indoor environments are estimated to save $17-48 billion in total health gains and $20-160 billion in worker performance. Source: Fisk, W. (2000) Health and productivity gains from better indoor environments and their relationship with building energy efficiency. Annual Review of Energy and the Environment: 25, 537-66.

  • Sustainable Building Operations and Maintenance Services

    Follow these sustainable strategies as your space renovations are complete and the building and interiors are operated in an environmentally sustainable manner. Operations staff should endeavor to establish best practices in energy efficiency, resource conservation, ecologically sensitive products, and other sustainable practices, and implement them.

  • Energy & Atmosphere

    Buildings and facilities rely on the operation of mechanical systems and electrical systems to maintain a comfortable indoor environmental quality for occupants. Building operations consume approximately 39% of the energy and 74% of the electricity produced annually in the United States, according to the U.S. Department of Energy. Greenhouse gases are generated and released throughout the life cycle of producing and consuming fossil fuel energy. These greenhouse gases directly contribute to air pollution and climate change. Therefore, atmospheric problems can be reduced by increasing the efficiency with which energy is used‚ optimizing the use of natural energy resources‚ and understanding the effects of energy technologies on the atmosphere.

  • Building Systems Upgrades

    The following are Sustainable Strategies to consider as your space undergoes a building system upgrade to improve energy, water use and occupant comfort. Refer to the Share Section for a representative project Case Study to discover key practices, benefits, results and checklists.

  • Under 10,000 SF Interiors Gut Rehab Project

    Following are Sustainable Strategies to consider as the space has or will undergo a major tenant gut rehab for projects under 10,000 SF. Note to use a current version of LEED for Commercial Interiors for tenant improvement projects over 10,000 SF. Refer to the Share Section for a represented project Case Study to discover key practices, benefits, results and checklists.

  • Spatial Equity

    Organizations today are less hierarchical and work is more team based, more mobile, and more cross functional. A key to spatial equity is that space layout and workstation standards are based on new ways of working and specific work tasks and business needs rather than organizational hierarchy.

  • Materials, Furniture, and Furnishings Replacement

    Daily wear and tear means that materials, furniture and furnishings require periodic replacement.

  • Plants / Planters

    Interior plants contribute to an aesthetically pleasing environment. There are several different types of indoor plants, all which vary according to the ease of growth and maintenance, resistance to pests, and efficiency at cleaning the air we breath. Foliage plants are great for indoor work environments because they dont flower and thus do not introduce allergens into the air. http://greenplantsforgreenbuildings.org

  • Lamp Types

    There are many different types of light bulbs / lamps used at commercial buildings including fluorescent, compact fluorescent, and Light Emitting Diode (LED). Incandescent lighting is becoming obsolete. Lamp selection should be driven by efficiency, lamp life, color quality of the light and its intended use. - Fluorescent lights do not give off as much heat, can be highly efficient and have a long useful life. However, they contain mercury and typically are not dimmable unless using a dimmable ballast. - CFLs can produce a warm light, are highly efficient and have a long useful life. However, CFLs contain small amounts of mercury and are also sensitive to frequent on/off cycling and as such their rated lifetimes may be reduced if switched on/off regularly. Not all CFLs are dimmable. - LED lamps do not contain mercury, are highly efficient, turn on quickly, are dimmable, and have a long useful life. LEDs are currently more costly and have a light quality that is typically whiter than incandescent.
