“Green” buildings use sustainable design principles to improve the health and comfort of the buildings occupants while reducing the negative environmental impact of the building. If planned properly, green buildings may not be more expensive to build than non-green buildings, and will have lowered operating costs as a result of efficient use of energy and resources. The goal of sustainable design efforts is to produce zero energy buildings which produce as much energy as they consume through energy efficient design and the use of renewable energy technologies. As part of your collaborative team, Hawkins Design Group Inc. will work with you to achieve:

Humans have used solar energy throughout history. We dried clothes, tanned hides, preserved meat and fruit, and purified water using solar power. Today we use solar energy to create energy necessary to power our modern and increasingly energy hungry world. The entire population of the earth consumes about 15 terawatts of power at any one time, using the available land we can easily support this with any combination of renewable sources such as wind and solar. Photovoltaic cells creates electricity directly from sunlight, that is essentially free and very reliable. The sun never sends a bill ! Therefor solar P.V. fixes the cost of energy, whereas the price for utility generated power is constantly increasing.

Many governments have plotted a course to take us off todays dependence on environmentally and financially unsustainable carbon and nuclear fuels. The world-wide government incentives, legal and monetary, has rapidly fueled the adoption of solar power plants; in the last 20 years the average growth of installed solar has gained over 40% per year, in the last few years it was closer to 100% per year. Any upfront investment in solar power plants is heavily outweighed by the tax benefits, accelerated depreciation, and potential marketing benefits.

Solar Photovoltaic power plants have the lowest possible O&M of all power plants, warranties on components is measured in decades. A well designed Photovoltaic system will last 25 to 30 years with no techicians, tools, road or grid. Financially these systems can provide very respectable returns on investment, providing a constant positive cash flow from the start, additionally producing revenue or savings that can far exceed the initial purchase price over the life of the power plant.

Energy costs and energy consumption are rising worldwide with expectations that this trend will continue into the foreseeable future. Identifying and maximizing energy saving solutions early in the planning process can save building owners and occupants hundreds of thousands of dollars over the life of the building.

Our sustainable design engineering teams will work with architects, building planners and owners to recommend mechanical systems, lighting design, electrical and plumbing infrastructures that will work together to optimize a building’s energy and utility efficiency

The “tools” to create lower energy costs have never been greater. With this rapidly changing technology, it’s crucial that “green” teams stay abreast of current developments of not only the technologies but their impact on the health and comfort of the building’s occupants.

Energy costs represent the highest payout of operational expenses. Therefore, much of the available national and international R&D funds are used to develop new systems for energy savings. Technologies such as photovoltaic panels are rapidly decreasing costs and payback periods. Other devices which may not be as well-known are:

  • Interior Lighting Systems
  • Heating, Cooling and Ventilation Systems
  • Highly Efficient Daylight harvesting and Controls
  • Energy cost reduction involves all systems within a building; heating/cooling, ventilation, lighting, windows and day lighting, plumbing and water use, and electrical consumption.

    According to the U.S. Department of Energy, commercial buildings consume 18% of total energy consumption and office buildings are the largest user within this segment. As the price of oil, gas, and other natural resources climbs, the costs of maintaining a less efficient building rise. Current expectations that these costs will continue to rise in the future, make energy cost savings a vital part of up fitting or new construction.

    Technology in this area is rapidly changing. As new more efficient systems become available, and costs come down on existing systems, installing state of the art energy efficient systems are good business investments. Just a few of the new systems and products available to reduce energy consumption are:

  • Lighting Controls
  • Variable air HVAC systems
  • Energy efficient lighting
  • Day lighting
  • Use of some or all of these systems can reduce energy costs. To further incentivize more energy efficient buildings, the Federal Government has initiated tax code changes allow for a tax deduction of up to $1.80 a square foot of building area for the installation of systems that reduce the total energy and power costs by 50% or more when compared to a reference building. The building systems eligible to secure the tax deduction include:

  • Interior lighting systems
  • Heating, cooling ventilation and hot water systems
  • Building envelope systems
  • The crucial element of sustainable design is good planning. Hawkins Design Group Inc. has experienced professionals who are familiar with all types of facilities, and understand the different design approaches required for successful sustainable projects. Because we stay current on all options available in sustainable design, our team of professionals add value to the projects by recommending design options in our areas of expertise to increase savings in construction and operational costs.

    Clint Rapier, P.E. | Vice President of Operations

    Clint Rapier began his engineering experience at HDG and has been with the Company for over a decade, serving in nearly every position prior to being named the VP of Operations. His earliest electrical design work began with residential work for a large local home builder, and has since worked up through both tenant improvements and shell building designs, to large scale industrial and production projects and most recently started the solar photovoltaic’s design division along with his duties of managing the overall firm as a business.

    Randy Dunton | Photovoltaic Power Systems Designer

    Randy Dunton began his career as a certified industrial electrician in 1980 and transitioned to computer engineering R&D to join the computer revolution. As a computer engineer Randy developed electronic circuits, software, and integrated circuits for the computer and consumer electronics industry, creating numerous patents along the way. In 2009 Randy transitioned to his newfound passion of solar power plant design, solar PV safety system R&D, and PV installer training. Through local community colleges Randy, used his self-developed curriculum, instilled the art of properly developing and installing safe and long lasting PV power plants in the rapidly growing PV installer workforce. Randy now designs commercial PV power plants for Hawkins Design Group; with the goal to help the world transition to a cleaner, more economic and more peaceful power source for our common future.
