LEED Certification Cost and Benefits Cheryl Birks
Mark Sanders GOAL: TO ANALYSE THE OPTION TO BUILD SUSTAINABLE BUILDINGS AND REDUCE THE STRUCTURE'S IMPACT ON THE ENVIRONMENT. Sustainability is defined as the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs. USGBC: Traditional buildings consume
72% of all electricity
39% of all the energy
produce 38% of CO2 emissions
use 40% of raw materials
produce 30% of waste
and consume 10% of potable water
AS A WORLD CLASS INSTITUTION, WSU HAS AN OBLIGATION TO PROVIDE ITS STUDENTS AND FACULTY WITH STATE OF THE ART BUILDINGS THAT PROMOTE SUSTAINABILITY TO THIS COMMUNITY AND OTHER INSTITUTIONS AROUND THE WORLD. THERE ARE MANY CATAGORIES THAT CAN HELP YOU ACHEIVE LEED CERTIFICATION POINTS, HOWEVER SOME ARE NOT AS APPLICABLE TO THE PULLMAN AND WSU CAMPUS AREA.
WSU pays $250,000 per year in stormwater taxes for the city to clean the pollutants out of the water. Instead of paying those taxes there are many things that WSU can implement for new construction projects to reduce the pollutants that could end up in our rivers. One option is to install pervious pavement on all roads and sidewalks. Pervious pavement allows water to flow through concrete and for stormwater to be stored in the concrete sidewalks and roads rather than run into receiving waters. Pervious concrete also has a unique ability to store heavy metals and fine grained particles. Although pervious concrete costs approximately 15% more than traditional concrete, the savings from stormwater taxes would pay for the extra cost over time. WATER EFFICIENCY Easily attainable fresh water is very quickly becoming a precious natural resource, and 5 of the possible LEED points are directly related to water efficiency. Pullman receives its potable water from groundwater contained in the Grande Ronde aquifer located hundreds of feet beneath the Palouse. Water levels have declined 1-2 feet per year. Due to the water being deep underground, it is not recharged from precipitation and therefore is a non-renewable water source. To achieve the points for water efficiency you must reduce the water usage of the building. In most properties this reduction can be achieved by implementing water-efficient landscaping designs. Property's water demand can be lowered by reducing the amount of high water demand plants. By installing plants native to the area you can still have a natural green looking environment without the high water costs. However, sometimes landscape design strategies alone are not able to reach a projects optimum water efficiency. Many innovative ideas can result in even the most arid environments becoming green and water efficient. One point can be obtained from reducing the wastewater and potable water demand. Buildings have been incorporating ultra-high efficiency toilets as well as waterless urinals to reduce the wastewater demand. It is even possible to reroute rain-water for the use in sewage systems. LEED recognizes developers use of high efficiency plumbing fixtures as well as performing on site treatment of the sewage. The combination of these items can reduce the amount of water used for sewage to a bare minimum. Another LEED point can be obtained from lowering the water usage of a building, this can be achieved by reducing the water use from water closets, urinals, lavatory faucets, showers, and kitchen or break room sinks. Luckily, WSU has already begun to implement some very crucial water reduction techniques. WSU pumped almost 479 million gallons of water to serve the Pullman campus. This total is most closely related to the amount of water used back in 1961. The graph to the right shows how WSU has been reducing its water usage over the years. EDUCATION AND AWARENESS SURVEY: Rate your knowledge of LEED requirements. How many LEED certified buildings do we have here at WSU? Do you believe that LEED certification can save money in the long run through operation costs? How strongly do you believe that state and federal buildings should be environmentally friendly? The survey showed that the average WSU student knows very little about LEED certification. Our goal is to start informing the WSU community what building infrastructure properties would change to achieve a LEED certificated status. Also, the public needs to know about the economic and environmental benefits that LEED certification can bring. The survey showed that people generally believe that creating environmentally friendly buildings is important. Thirty-two percent of the people who took the survey “strongly agreed” that federal and state buildings should be required to be LEED certified and another fifty-four percent “agreed” to this statement. The overwhelmingly positive response to this question shows that our generation really does care about the environment around them. INDOOR AIR QUALITY WSU should strive to design buildings that enable high productivity of the occupants. Studies by the USGBC indicate that the indoor environmental quality greatly impacts the productivity and learning capabilities of teachers and students. Adhesives and paints used in the constructions of rooms often contain VOCs which are known pollutants and can cause irritations to building occupants Occupants of buildings with high indoor environmental quality are healthier and happier. the health, happiness and productivity of both professors and students should be the biggest priority for Washington State University. As a learning and research institution, Costs LEED schools provide not only a better education environment but also save the school money in the long run while also being affordable to construct. It is possible to create environmentally friendly buildings without spending more money on construction costs. LEED buildings may not differ in costs at the beginning but they end up saving you approximately 8-9% in operation costs per year. LEED buildings use technology such as sensors to turn off lights when no one is in the room, and energy efficient appliances to lower the energy usage of the building. On average LEED buildings reduce their energy needs by 24% to 50% significantly lowering the electric costs encountered in the operation of the building. LEED buildings reduce on average 40% of their previous water use. LEED buildings reduce their solid waste consumption by 70% by providing recycling containers to recycle things such as paper, plastic and glass. WSU has two LEED certified buildings on campus. The Compton Union Building By implementing the use of dual flush toilets and water urinals the CUB is able to save 1,500,000 gallons of water a year.
This is a reduction of more than 30% of water use indoors compared to the old CUB
Uses light sensors to turn off lights when no one is in rooms such as bathrooms and the ballrooms
SILVER CERTIFICATION Olympia Avenue Residence Hall GOLD CERTIFICATION By only paying an extra $1,500 a year WSU is able to ensure that Olympia housing is run off of 35% of green energy
Both buildings were able to be constructed under their budget. The research has shown that the application of LEED design in future Washington State University construction will provide positive implications for both the University community as well as the Palouse as a whole. These features and others will reduce the impact on surface and aquifer waters which in turn will increase the life of the community; increase the health and productivity of students and staff members which will increase the success of students once they graduate; and produce awareness in the community about the importance of sustainable living. This research has also shown that these effects can be generated without spending more on initial capital costs and these implementations will save money on operating costs into the future.
