conserveAt Clark, we acknowledge that the challenge of climate change requires an immediate and thoughtful response from all of us. We are inspired by firms that are striving to meet sustainability goals. According to the USGBC, the construction industry accounts for 40% of worldwide energy usage, with building emissions growing and not shrinking. We are committed to reduce this trend, and CONSERVE™ is one of our firm’s seven core “branded services” that we leverage on every project.


Achieving environmental and sustainability goals begins in the early planning of our projects. Our Pre-Construction Team will join with and challenge our design & construction partners through a collaborative team approach, and set aggressive, but achievable, sustainable goals. Clark’s in-house team of diverse planners and experienced estimators gather and manage a prioritized collection of design ideas for the project, and then examine those items for their intrinsic value to the project, its stakeholders, and the environment.

The Clark Construction Budget Tracker and Planner allows us to seamlessly organize and clearly communicate the impact of any design element solution through all phases of design. The value of each proposed concept is developed through the implementation of:

  • Principles of Sustainable Construction
  • Value Analysis & Value Management Strategies
  • Life Cycle Cost Analysis of Systems and Materials

Some recent examples of Cost/Climate Value Analysis completed in previous project planning phases include:

  • Thermal Energy Storage Systems
  • Solar Power
  • Low Carbon Concrete Alternatives
  • Ground Source Heating/Cooling Equipment
  • Rainwater Harvesting
  • On-site Renewable Energy Generation
  • Outdoor Classroom & Natural Learning Space

Listening, educating, and challenging the team to offset the negative impact of traditional construction practices through exploration and assessment, will inevitably empower the team to innovate and make climate-positive decisions in every phase of construction.
Our processes enable us to forecast total cost of ownership (TCO) and return on investment (ROI), as well as bringing into focus the total investment per pupil (TIPP) and total investment per staff member (TISM). Ultimately, this ensures that the team is upholding our commitments to the community by responsibly allocating our investments to what we value most, your staff, visitors, patients, or students.


As dictated by our CONSERVE™ branded service, our jobsites will adhere to the following guidelines:

Waste Recycling

We have adopted stringent standards for waste recycling and minimization on all projects and we require new projects recycle a minimum of 75 percent of construction waste. Most projects exceed that goal, and in some cases, more than 95 percent recycling will occur. These efforts include a combination of creative strategies including recycling of raw materials produced in demolition, minimizing waste by asking suppliers to eliminate packing and shipping materials, and reusing building components.

Energy Conservation Measures

The major energy consumption areas during construction will be electrical energy, especially lighting, and temporary heating, as needed. The following five conservation measures will be considered:

  • Putting the construction electrical service on a timer to shut down after hours, with the ability to illuminate based on motion detection. This approach reduces energy consumption and enhances security, because anyone trespassing the site at night would be flagged from the motion detection.
  • Implement the use of high efficiency light bulbs  for temporary lighting.
  • Install a vestibule at the major trade entrance, and strip curtains at loading areas to reduce heat loss in the winter while doors remain open at times.
  • Install insulated plywood and insulated tarps for temporary protection of any area.
  • Expedite installation of insulated Low-E windows and facade/enclosure materials prior to the winter construction heating season.

Methods of Construction Waste Minimization

  • Provide separated dumpsters for the major recycled materials (metals, wallboard, cardboard, masonry) and designate a laborer to sort this trash into the appropriate containers.
  • Purchase materials specifying minimal packaging and require truckers to haul off major packaging materials at time of delivery. Also minimize truck idle time on site.

Reduce Job Site Chemicals

  • Maximize implementation of LEED guidelines to specify low-VOC materials.
  • Require pre-submittal MSDS sheets for any chemicals before they are brought to the site, with a statement of intent. This will prevent contractors from bringing random chemicals on site without proper notice or management, and will discourage use of chemicals that are not required for the installation process.
  • Implement a pre-fabrication program to assemble building components to the fullest extent off-site. This moves the use of many adhesive and finish chemicals to a controlled, ventilated shop environment, where they can be managed more effectively.
