Sustainable construction

Project Description

How We Built A Geothermal Heating System? Geothermal systems are one of the best ways to efficiently heat or cool a building with a renewable source. It uses the naturally cool temperatures below ground to cool water in pipes and then runs it through chilled water coils, just like a chilled water system. The project met the LEED standards for sustainable construction by providing these features, which aren’t included in normal electrical utility bills. 1) Understanding Building Climate: While it’s important to make sure your HVAC is functioning properly, it’s also important to keep in mind your building’s climate. If you live in a dry climate, for example, you will need different equipment than if you live in a wet climate. The more knowledge you have of your building’s environment, then, the better equipped you are to create an air conditioning or heating system that will function most efficiently. 2) Designing A Geothermal Heat Pump System: If you are considering using geothermal for your heating and cooling needs, it is important to remember that there are many options for harnessing ground-source heat. Two of these options—geothermal heat pumps and direct-exchange systems—are discussed below. Both can be used in any climate, but because of their higher initial cost, they are more commonly used in regions with moderate climates. Also consider whether you will need backup space heating or air conditioning during extended periods of cold or hot weather. Always consult a professional HVAC contractor to evaluate your individual site conditions before deciding on a particular system. 3) Planning For The Installation Of A Geo-Exchange Heat Pump: Before you begin any large project, it’s important to take your time and plan for every contingency. If you want to install a geothermal heat pump in your home, start by planning ahead so that every step runs smoothly. 4) Installing Pipe Run Underneath Your Property: Installing a geothermal system may involve digging a trench underneath your property, running pipe through it, and connecting it to a heat pump at your building. One great thing about geothermal systems is that you don’t have to dig deep trenches—usually no more than 12 inches below ground—and they can be hidden from view quite well. In fact, much of the pipe work in a geothermal system can run along an existing wall or floor joist where pipes are already concealed from view. 5) Installing Chillers And Condensers For Cooler Water: Installing a chiller and condenser will allow you to harness cool water below ground and run it through your air conditioning system, giving you up to 30% more cooling power. With a geothermal heating and cooling system, your air conditioner runs at peak efficiency with little waste of energy or money spent on gas-fired equipment. These systems use only renewable power from underground that's naturally replenished each year by evaporation from reservoirs – so there’s no pollution or environmental damage. The savings you’ll enjoy on your utility bills every month will make it one of the best investments you can make in your building. 6) Preparing For Heat Recovery Units: Heat recovery units (HRUs) use a heat exchanger to transfer heat from exhaust air to fresh air. They’re usually powered by electricity, but may be powered by solar or geothermal energy in some systems. Solar or geothermal-powered HRUs reduce electrical consumption and reduce operation and maintenance costs for buildings without requiring expensive equipment. Overall, they’re a great way to improve comfort and save money on heating and cooling bills while reducing your building’s environmental impact at the same time. At their core, HRUs provide excellent building performance; however, if you’re considering installing an HRU system, it’s important to keep these considerations in mind: 1) placement of unit; 2) type of unit; 3) equipment requirements; 4) ductwork requirements; 5) costs associated with installation. Each will vary according to project specifics.
