So what is exactly sustainable design, is it solar pv, vegetated roofs, No VOC’s – how can you describe it to your client in a way that makes sense and makes them want to give you more money for delivering a better product.
Energy star is the most widely known and accepted green system on the market. People understand that logo means that the product will not use as much energy and will save them money.
This is a product specific rating system that is rapidly growing. It looks at materials from their chemical compositions and has a very high standard of measure.
Focused on air quality and off gasing of materials.
Introduction of presenter
The most basic understanding is what climate you are building within and what that means for the building. We have heating and cooling days and very humid days. We need our buildings to be air tight and vapor permeable. In another climate – let’s say in Florida, they don’t have many heating days, so the building envelope will be constructed differently. There are not mandatory decisions that need to be made in every situation, you have to look at the factors for the particular building and site you are working with.
Don’t’ over build. Use space efficiently – this only saves money for the client.
How you orient the building may lead to pv in the future or simply passive design that reduces energy use.
How should you insulate the building. There is not one correct answer. It depends on the project, location, and budget. ICF is the tightest envelope, but it takes more square footage, spray foam has a chemical in it that is not right for everyone.
Giving the power of control to an individual for that individuals area has been shown in many studies to reduce cost for the operation of the facility. Being able to turn your light off or turn your thermostat up / down or only use a reading light will reduce energy demand.
Lighting technologies are progressing. LED lights don’t have the same light splay as we are used to, fluorescent lights have mercury. There needs to be consideration of all the factors of each product selected. Perhaps some of each type of light is the correct decision along with some daylighting.
Testing the air systems is also important, knowing where the leaks are and sealing ducts to prevent leaks lead to cost savings a certifications in the end
Introduction of presenter
Rapidly renewable materials are sometime used as the solution that leads to problems. You have to be careful with every decision made through the process.
Regional materials are always a good choice as you don’t have to pay for shipping.
Concrete can have a high percentage of recycled content if you ask for fly ash, but what does that do to the structural integrity of the material, what about using american steel, or crushing recycled content for base
Why do we frame everything at 16” centers? Would 24” centers work just as well. Can we use materials better? Thinking holistically could reduce the amount of materials in a project saving the client money.

Water heater options vs a standard water heater.
Introduction of presenter
Do you want to build a building on the best piece of the property or do you want to preserve the “view” to enhance the project and place the building on the less desirable location aesthetically. If you clear cut the lot, how will that impact the trees around the lot, what will happen downstream when the trees are not there to suck up the rainfall. Will you get negative publicity because of smoke or air pollution problems.
Introduction of presenter
FSC – why only one certification, it offers third party verification and stricter rules through out the chair of custody. This one is hard to implement if cost is the basis for decisions.
No VOC materials and understanding those materials is very important. Is there a radon problem in your area? Does the client react to chemicals? Will there be animals inside the structure?
Proper outdoor ventilation is critical when you build a tight structure. It is mandatory in commercial structures that you consider it, why not in homes?
Making sure the end user understands how to run the facility. How do you clean a bamboo floor, can you scrub a no voc pain wall, how do you program the thermostat?

Green Design = Quality Design and Quality Construction
What is the first step to going green?•Evaluate where you are now and where you want togo with your effort. •Do you want to save money / energy? •Do you want to reduce your carbon footprint? •Do you want to preserve resources for the future?•Technical evaluation of the house, system thinking(process and products) •Low hanging fruit•Professional integration – architects, interiordesigners, engineers, builders, trades •Do you need more expertise? •Do you want to go towards a deeper green?
How do you define green?•Carbon Footprint Calculators •How many people in the family? •Size of the House •Is it energy efficient? •Do you use energy efficient lighting? •Energy Star? •Hot Water Use? •Travel or stay home •Do you eat meat? •Do you eat organic food? •Do you recycle•www.nature.org (The NatureConservancy)•So my carbon footprint is 83 belowthe national average of 110 now what?

What is GreenBuilding?as green construction also known or sustainable building, is the practice of creating structures and using processes that are environmentally responsible and resource- efficient throughout a buildings life-cycle: from siting to design, construction, operation, maintenance, renovation, and deconstruction. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. http://en.wikipedia.org/wiki/Green_buildin g
LEEDigation•Is it Different Than•Ordinary Litigation?
Law Ark Building Blog― The bad news is that attorneys, especially those already practicing in construction law, will soon realize that aside from green design and construction’s sometimes specialized and occasionally ill-defined vernacular, there’s no real novelty in the types of claims that might arise. No new frontiers of jurisprudence need be explored–a leaky green roof is still a leaky roof–whether it also requires regular mowing and landscape maintenance changes little from a legal perspective. http://www.lawarkbuilding.com/?p=104
Best Practices Construction Blog― Cole may be right that there is no novelty to the traditional types of claims (contract, tort, statutory, etc.) that may arise in green construction disputes. However, the novelty in the green building industry is the new set of standards that will inevitably become part of the legal dispute. In other words, while ―a leaky green roof is still a leaky roof‖ … there will be new risks to be allocated, different types of damages lost, additional players involved, varied proof required and, yes, perhaps a novel cause of action alleged because that leaky green roof system failed. http://bit.ly/diszmS
Still... Unmet Expectations • Energy Performance: Is the building’s energy systems performing as expected (or promised)? • Rating: Did the building achieve the planned LEED rating or other certification? • Long-Term Sustainability: What is the project’s impact on the environment, and is this as expected?
Shaw Development v. SouthernBuilders • Problem: Contract required building to meet Silver Certification. It didn’t. • Whose Fault?: Developer sued builder, but there was no clear allocation in contract of who was responsible for certification • Damages: $700k+ in lost tax credits • Result: Unknown - Settled.
Washington DC v. WashingtonNationals • Problem: Expectations for ―Green‖ LED Scoreboard wasn’t met. Owner claimed project wasn’t substantially complete and withheld funds. • Damages: Not too clear in settlement materials released, but $3.5 Million was withheld based in large part on the scoreboard dispute. • Result: Unknown - Settled.
Show Me The Money! • Tax Credits: Missing a certificate level can effect tax credit eligibility • Energy Efficiency: If property is not as energy efficient as promised, damages can include increased energy costs
Unique Damage Situations • Missing Certification: If a property expects to have Gold certification, but only gets Silver, and this doesn’t have any tax credit implications...what are the damages? • Goodwill: How will courts calculate loss of good will if green construction misses expectations.
Unique Liability Situations • LEED Responsibility Allocation: Responsibility for LEED points is distributed between architect, owner and contractor. If energy efficiency is not as expected, how do you assign liability? • Energy Efficiency: Energy efficiency of a building relies on factors: (i) climate; (ii) property placement; (iii) property use; (iv) etc. How do you clearly blame a party for inefficiencies.
Preparing for theRisk • Control Expectations • Limit Exposure By Contract • Be Careful, and Keep It Simple
Control Expectations ― ...Expect the unexpected. Always sounds like good advice. Except, of course, if you are expecting the unexpected, then well then it really isnt really unexpected anymore. Is it? And that leaves you vulnerable to the truly unexpected. Because, youre not expecting it.
Control Expectations • Clear terms identifying scope of work • Clear terms in Subcontracts • Very specific specifications, making them as independent from specific certifications as possible • Get team together ahead of time (BIM, Charette)
Shaw Developmentv. Southern BuildersContract required ―Silver LEED Certification,‖ but lackedclear specifications.Two lessons:- Builder’s obligation to achieve certification and build tospecs must be aligned;- Certification is not a guarantee, and architects /builders should be weary of promising a certification.
Limit Risk in Contract • Avoid warranties of long term energy performance • Set performance expectations at time building complete, not some time in future • Clearly allocate responsibilities between owner, builder and architect • Get LEED AP to consult
Things That Affect A Building’sEnergy Performance A building’s energy performance can be a very complex matter, affected by things out of the builder / architect’s control: - Climate - Use and Users of Building - Third Party Interference
Allocate ResponsibilityThe LEED Program allocates responsibility for pointsbetween the Owner, Builder and Architect.It is an error to not allocate responsibility for greenbuilding design and construction when contracting.
Non-ContractualActions • Check and Double Check Subcontractors’ and Consultants’ Credentials • Be Careful with Advertising. Keep it Simple and Don’t Greenwash. • Require Communication in Contract • Consider Green Building Insurance
What is Green Washing? Greenwashing (green whitewash) is the practice of companies disingenuously spinning their products and policies as environmentally friendly, such as by presenting cost cuts as reductions in use of resources. It is a deceptive use of green PR or green marketing. The term green sheen has similarly been used to describe organizations that attempt to show that they are adopting practices beneficial to the environment http://en.wikipedia.org/wiki/Greenwash
Novel InsuranceProducts • Green Washing Insurance • Green Certification Insurance • Heightened Risk caused by certain green building practices like Vegetative Roofing, Alternative Energy Generational Systems, etc.
