Energy efficiency is a must. Our energy vision for a new city hall is way above the most efficient building stock: run it as one-fourth to one-third of current energy load. One-fourth of the energy could be produced on site – solar, electric. Envision a building where the power could go out and no one notices for a few hours. How to eliminate waste in use of building? Not convinced of photo-voltaics in this climate. There is a wall of them in Lillis but not integral to the sustainability of the building. Solar panels have payback in a year, expensive to make but good payback. We have them locally. Learn from the Lillis experience. Be careful that what you are proposing works. Work with the climate and with what is free. We need to think about behavioral adaptation. One thing people were expecting in the new Federal Courthouse was air conditioning and not all areas have it. Cooling – having a vegetative roof; it greatly helps. Can you capture the daylighting after it has penetrated the building? The Federal Courthouse allows for every part of interior space to receive natural light. Find out if there is any passive solar energy as a result and if their energy consumption is reduced. Could you emulate it and make use of it? How to get rid of heat, not add to it, is key. How can we use heat instead of throwing it away? Use waste heat from computers. Roof extending well beyond the walls is a good concept to reduce glare, heat. Deconstruction is an important part of sustainable practice. It’s expected that deconstruction of the existing City Hall could achieve 95-98% waste diversion. Don’t let deconstruction flow out into the right of way, which is hard for alter-abled access. Learn from the take down of the existing City Hall what might make the take down of next one easier. How can we take apart a building without use of fossil fuels (heavy equipment)? Use reduce, reuse, and recycle as a guiding principle for design process. Ask do you really need to have an element that will later need to be recycled? Fully acknowledge the urban context. An underused and unkempt open space is worse than having great architecture. Don’t create something suburban. Show the community what density and urban buildings can really be. We really need to look at density. Love the idea of a temporary open space that can be built in later if needed (for future expansion). Create a truly urban building. While you say there are inefficiencies having services spread out, it makes the city more livable because workers support other services. Don’t want building to be isolated.
