Low Impact Development Land planning and engineering design approach Conservation and use of on-site natural features to protect water quality Consists of a series of small-scale hydrologic controls to replicate pre-development conditions Infiltration, filtering, storing, and detaining runoff close to where the rain falls and designed to mimic pre-development conditions Go over Syllabus Please read your syllabus on Class participation, classroom conduct, etc. Pay attention please to the Fragrance Policy – I for one am chemically sensitive Field Trips – try to schedule a few for extra credit – see Guild event handout, ask if students have other suggestions, site tours

Impacts on Hydrology from Development, Before & After Water hydrology BEFORE development Water hydrology AFTER development CAO Philosophy – too much in green building to remember everything If I can’t recall the name of a product or a project, I will research it for you and get you an answer If I don’t expect myself to remember everything, I shouldn’t expect that of you, so Final Exam will be open book, That means questions will be harder – OK?

Site Hydrology Understanding how water moves across a site before design Groundwater Recharge Where is the stormwater naturally infiltrating into the ground to recharge aquifers or groundwater? Topography How, and where, does stormwater move across the terrain? Where is is draining, where is it accumulating? My husband always uses this quote. Please respect other’s work, including my own. If you quote another provide the citation. Source: UW College of Engineering gsapubs.org

Green Landscaping Design – Site Protection in the Built Green Checklist Avoid Soil Compaction (2-4) Soil compaction harms plants and encourages run-off Preserve Existing Native Vegetation (2-5) Native vegetation is adapted to our climate conditions, retaining native species helps with erosion, sediment, and dust control Retain 30% of Trees on Site (2-6) Trees moderate temperature and help to control the urban heat island effect, they also add value Retain or Add Deciduous Trees Southside (2-7) Properly placed trees reduce heating and cooling costs If Building Near Critical Areas, Preserve and Protect Beyond Code (2-9) Set Aside Percentage of Building Site to be Left Undisturbed (2-10)

Green Landscaping Design – Water Conservation in the Built Green Checklist Amend Disturbed Soil with Compost (2-15) Compost aid is water retention of the underlying soil, thus less water is required to nourish the plants Mulch Landscape Beds (2-36) Mulch helps to minimize weeds Limit Use of Turf Grass (2-37 – 2-38) Turf grass required watering and maintenance Landscape with Appropriate Plants (2-39) Correctly selected plants help to reduce watering requirements - right plant, right place Sub-Surface or Drip System Irrigation (2-41) Sub-surface or drip irrigation systems use significantly less water compared to “pop-up” above-ground systems No Irrigation after One-Year (2-42) NW Bloom The energy crisis spawned the green building movement in the 1970’s November 15, 2009 An oil rig in Taft, California. – article talks about how the credit crisis will be over long before the energy crisis

Green Products for Site & Water Outdoor Water Conservation Indoor Water Conservation Simple rain barrel roof-top collection for irrigation Faucet aerator Low-flow showerhead Rainwater Collection Major cistern to collect rain water for multiple possible uses - irrigation, toilet-flushing, or laundry, as is allowed in the City of Seattle Reduce Reuse Recycle – that’s how we all got started in the late ’80’s Several major categories of material efficiency are used in green building Material Use refers to how materials, projects, and products are designed – the emphasis here is on waste prevention Material Reuse – another way of waste prevention – reuse a material in it’s existing state before recycling or disposal Who can describe what deconstruction is? Where can you find deconstruction services? Recycling – taking waste material that can not be reused to a facility for transformation into another product – sometimes the same product, often time not. Green Products Dual-flush toilet - 0.08 gallon flush for liquid waste, uses ½ the water Composting toilet – some models don’t use any water

Innovative Strategies for Better Water Efficiency and Use Built-In Composting instead of putting food scraps down the drain with a garbage disposal, helps to eliminate unwanted materials that ultimately travel to and pollute Puget Sound Easy DIY Greywater Recycling System: Sloan Aqus Greywater Recycling - uses waste water from the sink as the water source for flushing toilets, thereby eliminating the use of drinking water as the initial source.

Built Green® - Site & Water Sections Site Protection Water Protection Environmental Design Concepts Example: Build on an Infill Lot Example: Install Rainwater Collection One of the complexities around green building is terminology. No one really agrees on the terminology NAHB, a leading building association says it’s defined this way. There are many in our own communities, and even in this room would would say this definition falls way short of the mark and only goes after the low hanging fruit Speaking of terminology What’s Green Building versus Sustainable Building? Are they the same, interchangeable? NAHB would say yes, I say no… Example: Position Garage 15

Site Protection in the Built Green Checklist Protect Site’s Natural Features Protect Natural Processes On-Site Impervious Surfaces Eliminate Water Pollutants Pervious Concrete Demonstration Although there is no standard definition, generally we all agree on the elements of green or sustainable building. Preserve Existing Native Vegetation – Big Wood at 92nd Street, Mukilteo, WA Pervious Concrete at Stratford Place, Sultan WA

Water Protection in the Built Green Checklist Drip Irrigation at Snoqualmie Gourmet Ice Cream, Maltby, WA Install High Performance Low-Flush Toilets Although there is no standard definition, generally we all agree on the elements of green or sustainable building. Install Whole House Water Filter System

Environmental Design Concepts in the Built Green Checklist Provide Accessory Dwelling Unit Provide a Front Porch So what’s green? It all is, as long as you understand the distinctions. Because the difference is in the details. Any “Green Home” can have elements from the 5 sustainability categories – Energy Efficiency, Indoor Air Quality, Water Efficiency, Resource Efficiency, or Site Management – but which ones and how many. That’s where you have to do your homework and you need to understand the difference in the details. Not all HVAC systems are created equal. Was the forced air system sealed? With what? Was it cleaned before operation? Does that “low-VOC” paint contain toxic pigments? Does the natural ventilation work? Was it designed properly? So you are collecting rainwater – off an asphalt shingle or metal roof? So the particle board used for the cabinets has no added urea formaldehyde, but but do they have cheap wall-to-wall carpet? This class is going to teach you how to identify green building and how to distinguish among the shades of green. Build North Area of Lot First June Conway.com

Next Class Energy Performance NW Energy Star Homes Green Products Energy Upgrades Energy Efficiency in Built Green No standard definitions exist, part of the problem having green building go mainstream I like to talk about the shades of green – because any time someone incorporates a green building product, feature, technique or strategy into a project, it’s better than it was before. So we talk in terms of light green and deep green. I like to consider different levels of green Green Building lite – some energy features, some water, generally no major green materials Sustainable Building – more comprehensive approach Healthy Homes – feature emphasis on indoor air quality, can include major green materials To help differentiate among green building types, levels, etc. Green Building certification programs level the playing flied How many are familiar with these programs? What do you know about how these programs work with the MLS?
