Site Stewardship: Building Without Damaging What Is Already There

When people hear the words green building, they often think first about solar panels, insulation or energy-efficient heating.

Those things matter, but a sustainable building begins before the walls go up. It begins with the land beneath it, the water moving across it and the neighbourhood surrounding it.

The LEED Canada for Homes framework provides a useful way to examine these relationships. LEED—Leadership in Energy and Environmental Design—looks beyond one feature or technology. It asks how decisions about location, land, water, energy, materials, indoor air quality and occupant education work together over the life of a building.

A home can be efficient after it is completed while still causing unnecessary damage during construction. Soil may be compacted, vegetation removed, sediment washed into storm drains and neighbouring properties affected by dust, mud or altered drainage.

That is why one of the earliest subjects within LEED’s Sustainable Sites category is LEED Site Stewardship.

Looking at the Whole Building

The LEED Canada for Homes framework organizes sustainable building decisions into eight broad categories:

• Innovation and Design Process
• Location and Linkages
• Sustainable Sites
• Water Efficiency
• Energy and Atmosphere
• Materials and Resources
• Indoor Environmental Quality
• Awareness and Education

These categories contain more focused prerequisites and credits, but the larger message is straightforward: a building is not a collection of separate parts.

Its location influences transportation. Its orientation affects sunlight, heating and cooling. Its landscaping influences water use and stormwater runoff. Its building envelope affects the size of its mechanical systems. Its materials affect durability, waste and indoor air quality.

Change one part and we may affect several others.

Better Decisions Begin Before Construction

One of LEED’s most important principles is the integrative process.

Instead of designing a building first and trying to make it sustainable afterward, the owner, architect, engineers, builders and other participants establish the project’s goals early.

Before major design decisions become difficult or expensive to change, the team considers how the site, building orientation, drainage, energy, water, materials, indoor environment and long-term operation will affect one another.

A decision in one area may create benefits elsewhere.

Preserving existing vegetation can reduce erosion, absorb rainfall and lower summer temperatures. Building orientation can improve natural light while reducing heating or cooling demand. Better insulation, windows and airtightness may allow the building to use a smaller heating system.

In that sense, sustainable design begins before the detailed drawings—not with a particular product, but with better questions.

What Is Site Stewardship?

Site Stewardship begins with a basic question:

How can we build on this land without unnecessarily damaging the natural and community systems already working there?

In practical terms, responsible site management can include:

• protecting existing trees and vegetation;
• limiting where construction equipment travels;
• avoiding unnecessary soil compaction;
• preserving or properly storing topsoil;
• keeping excavated soil and sediment on the site;
• protecting storm drains and nearby waterways;
• controlling mud, dust and runoff;
• restoring disturbed areas promptly.

None of these practices is particularly glamorous. Most will never be noticed once construction is complete.

Yet they can determine whether the finished property absorbs rainfall, supports healthy vegetation and fits responsibly into the surrounding neighbourhood.

Soil Is Part of Our Infrastructure

Healthy soil performs work.

It absorbs rainfall, supports plants, stores carbon and helps regulate how water moves across a property. Once soil is heavily compacted by machinery, its ability to absorb water may be substantially reduced.

Rainfall that once soaked into the ground can begin flowing across the surface. That may produce standing water, carry soil onto streets or create drainage problems for neighbouring properties.

Adding a thin layer of topsoil after construction does not necessarily restore the soil structure that was lost.

When we think of infrastructure, we tend to picture pipes, roads and treatment facilities. But healthy soil, vegetation and natural drainage also provide services to a community. Protecting those services can reduce the demands placed on constructed infrastructure.

Erosion Does Not Respect Property Lines

Loose soil does not necessarily remain on the construction site.

Rain and melting snow can carry sediment onto streets, into catch basins and through stormwater systems. Depending on where that water travels, sediment may eventually reach wetlands, creeks or rivers.

Preventing erosion at the site is generally simpler than cleaning sediment from public infrastructure or repairing damage later.

Site Stewardship therefore connects a private construction decision to public drainage systems, water quality and municipal maintenance.

Existing Vegetation Has Value

Mature trees, shrubs and established ground cover already perform several useful functions.

They hold soil in place, intercept rainfall, provide shade, moderate summer temperatures and create habitat. Their roots also help maintain soil structure and water infiltration.

Removing vegetation may sometimes be necessary, but clearing an entire site simply because it is convenient can create avoidable costs. New landscaping then has to replace some of the functions that the original vegetation was already providing.

The most sustainable landscaping may be the landscaping we did not unnecessarily remove.

Construction Happens Within a Community

A building site may be privately owned, but its effects extend beyond its boundaries.

Dust can affect nearby homes. Mud can be carried onto public streets. Changes in grading can redirect water. The loss of vegetation can change the appearance, temperature and drainage of an area.

Site Stewardship recognizes that construction does not take place on an isolated drawing. It occurs beside neighbours, roads, utilities and natural systems.

Good site practices are therefore not only environmental measures. They are also acts of community consideration.

Does LEED Have to Cost More?

LEED is sometimes dismissed as being much more expensive than conventional construction.

That assumption often combines two different things: the cost of pursuing formal certification and the cost of building more responsibly.

Certification involves documentation, professional coordination, verification and associated fees. Some high-performance features may also increase initial construction costs.

But many LEED principles concern decisions rather than expensive additions—protecting soil, reducing unnecessary disturbance, orienting a building properly, coordinating systems and avoiding waste.

The integrative process can also reveal savings. When decisions are made early, one improvement may reduce the need for something elsewhere. It is generally less expensive to design systems to work together from the beginning than to correct problems or attach “green features” after the building has already been designed.

The 50-Year Question

Construction decisions should not be judged only by what they cost on opening day.

They should also be judged by what the building will consume, maintain, repair and replace over its useful life.

Consider a project pursuing a target of using 35% less energy or water than its conventional baseline. That percentage is not a guaranteed result of LEED certification; it is an example of the kind of measurable performance target a project may pursue.

The important point is that the benefit does not occur only once.

Lower energy and water consumption can produce savings this year, next year and for decades afterward. Over a 50-year service life, those recurring savings can outweigh a relatively modest increase in initial construction cost.

The calculation should include more than the owner’s utility bills:

• First cost: designing and constructing the building.
• Operating cost: energy, water and routine maintenance.
• Renewal cost: repairing and replacing systems and materials.
• Community cost: infrastructure capacity, runoff, waste and environmental effects.
• Life-cycle cost: the combined consequences over the building’s useful life.

Lower water demand can reduce pressure on municipal treatment and distribution systems. Lower energy use can reduce peak demand and exposure to rising costs. Durable materials and well-integrated systems can reduce maintenance, premature replacement and waste.

One better building may produce modest community benefits. An entire generation of better buildings can influence future infrastructure needs.

Certification Is Not the Only Value

A project does not have to pursue formal LEED certification for these principles to be useful.

LEED provides homeowners, builders, architects, planners and municipalities with a structured set of questions. Certification adds independent documentation and verification, but the underlying practices can still improve ordinary homes, public buildings and municipal development standards.

We can use the framework to ask better questions even when no plaque will be placed on the finished building.

Site Stewardship may appear to be a small construction-site concern. In reality, it connects private development with public drainage, water quality, neighbourhood comfort, urban vegetation and future maintenance costs.

The first question in sustainable building is therefore not simply:

What are we going to build?

It is also:

How can we build it while protecting the land and community systems already supporting us?

In future articles, we will continue exploring the LEED framework and how its principles can help us make better long-term decisions about our homes, public buildings and community development.
