While governments have a role in shaping and improving the built environment through zoning, development bylaws and other means, developers also play a large role. They choose where to build, the types of homes or buildings that get built, and many of the details that make up a home, neighbourhood and community.
The better developers and builders know how to both built better and sell better. What I mean by 'selling better' is that they can explain the merits of their project, why they have gone above and beyond the typical minimums, and how they will offer you an improved quality of life.
They can take the less fascinating construction details we normally aren't interested in, and provide homeowners with valuable insight into the inner workings of their home. This helps the future homeowner understand why one house’s fan, flooring, and air filter leads to improved indoor air quality, which in turn can improve human health, or how more insulation and improved windows can lead to lower energy costs.
One example of a progressive developer isParkLane Homesbased in Vancouver, BC. ParkLane is going above and beyond municipal requirements while developing a 15,000 home development along the Fraser River over the next decade.
The community is called theRiver District, and it is being built on former industrial lands that have been unused or underused for many years. Right now it is the single largest residential community development project in Vancouver and it demonstrates what a well planned project can be.
When someone talks about the desirability of a community, they often think of their home or neighbourhood on a beautiful sunny day. People are increasingly considering not just how a home or community performs on a great day, but also how it will perform when times get tough. How will it handle excessive rain or powerful storms? River District is being designed to be a great neighbourhood even during the most challenging times.
While the city requires developers to look at the water levels expected during a once in 200 year storm, ParkLane went much further and had a study completed looking at what the projected sea levels would be in 100 years if climate change continues unchecked.
Due to the results of that study, the site will be raised up 4.8 meters to accommodate that potential future scenario and improve security for new homeowners. ParkLane is also reconstructing and rehabilitating the foreshore to build fish and bird habitat. This will also help to improve the water quality in the Fraser River, while at the same time making the area more enjoyable for residents.
The community will also be designed with rain gardens built into the street network to improve the water quality returning to the Fraser River from the site. Throughout the site, green space is being built to offer habitat for songbirds that live near the water.
The waterfront will all be publicly accessible with walking and biking trails, along great access to an existing a public pier.
The resulting development will be able to handle a once in 200 year storm, based on the expected sea levels in the year 2100. The developer has greatly surpassed requirements, helping to create a more resilient community while giving their clients much more durable homes.
In addition to a safer base elevation for the community, all buildings and homes in the development that have mechanical rooms located in underground parking garages will have them well-protected in watertight rooms with watertight doors.
在超级飓风桑迪(Super Storm Sandy)袭击纽约期间，许多建筑虽然没有受到太大破坏，但由于地下室被淹，供暖系统不再工作，仍然无法居住。在河区采取的额外耐用措施提供了安全，以防止由于风暴而导致的机械系统故障。
ParkLane is also the first developer in the city to build and operate its own district heating system. A high efficiency natural gas plant will heat the community during construction, and while future options for district energy are considered (district energy refers to energy generation systems dedicated to an individual community).

区域能源系统的最大优势之一是，整个混合使用社区被连接起来，以平衡商业和住宅建筑之间的能源负荷。由于商业建筑通常在白天消耗更多的电力，而住宅使用往往在晚上增加，这导致系统可以运行更接近理想的输出，因此能源产生和分配更有效。
The community already has an off-street bike path and pedestrian network, with great expansion plans for the future. In their presentation center you can use an interactive display to see all the ways you will be able to get around the neighbourhood by foot or bike.
There is also a working rail line which could be an asset in the future. Pedestrian and bike routes through the community will eventually connect the school, community center, day care, grocery store and coffee shops when the community is complete. Residents and visitors will be able to walk, ride, or stroll to meet their daily needs.
So while even to the casual observer it is clear that world is changing rapidly, there is much we can do to reduce climate change and adapt to what does occur. While wearing rubber boots might not be the best adaptation strategy, they are now being sold in tourist shops in Venice where many squares regularly flood now.
Other strategies such as building and repairing shorelines to protect some costal developments, relocating others, and in the case of new development, avoiding flood prone areas or building with climate change and storms in mind.
So when you are looking for a new place to live, ask the developer or builder a lot of questions. Find out what they are doing to make the home or development healthier and safer, a better investment for your family, and more sustainable for the community. There are many great developers out there.
