1. All About Location
While building an energy-efficient home, location, shape, and construction materials are prime considerations that will significantly influence the heating and cooling requirements. The maximum use of passive solar energy gain in winters and reduction of the heat gain during summers is the ideal scenario. It is achieved by optimizing the location, orientation, and landscaping of the home.
Home orientation determines how much sun your house will be getting. This has a direct impact on your home’s temperature.
Design the home to take advantage of different sun angles. The midday sun is at a low angle in winter and a high angle in summer. Based on this, position your home to reduce heating and cooling expenses. Homes situated on the south side of the street-facing north get a lot of sunlight at the back of the house. Homes on the north side get shade during the summer afternoons in their backyards. Similarly, if you’re living in a colder climate, you’d want to choose your windows’ location to be able to absorb maximum sunlight. South-facing homes capture sunlight in the winter while blocking it during summer.
Such strategies can make a huge difference, and you’d be able to enjoy summers without your house being overheated. For instance, if the building is constructed in a way that is not exposed to the sun, walls are insulated, or the glass is shaded, then the solar gain is minimized. The cooling requirement will ultimately decrease, which would help you in conserving energy. But the tradeoff is a lower solar gain in the winters; however, if you live in an area that experiences short winters, then this is ideal for you.
2. Landscaping & Shade
Landscaping using elements of shade can help prevent your house from absorbing excess heat, in fact, they help reduce the temperature by up to 6 degrees. You can utilize trees with canopies such as Yellow Buckeye and London Planetree to provide shade to your home. For blocking summer heat and letting the sunlight in during the winter, go for deciduous trees. They are perfect for both seasons as they bloom in spring/summers and lose their leaves in winter. To provide continuous shade and to provide protection from strong winds, go for dense trees and shrubs.
Planting location is also crucial. Planting trees on the east, south, and west sides will keep your house cool during periods of extreme heat. East Trees cast shadows on your home in the morning sun. South Trees cast shadows on your house in the mid-morning and early afternoon. Trees planted on the west cast shadows to block the afternoon sun when the temperature is extreme, making them the most impactful in reducing your energy bills.
3. Ventilation Systems
A well-designed ventilation system for an energy-efficient house doesn’t only provide comfort but also helps in energy saving by preventing the overuse of electrical appliances used for heating and cooling purposes. Moreover, home ventilation also filters out contaminated air. The simplest form of ventilation systems are windows and mechanical systems with fans used to keep the interior pleasant. Your home design should ensure healthy and natural ventilation.
The ventilation system is an integral part of your energy-efficient house design because it moves air and moisture across the building envelope’s barrier, and sometimes it also moves heat. A well-thought-out ventilation system can significantly minimize your overall energy usage and help make your home more energy-efficient.
4. Energy-Efficient HVAC Systems
The U.S. Department of Energy estimates that heating and cooling accounts for 48% of energy use in an average U.S. home. This research shows that HVAC systems are among the largest energy consumers. Installing an efficient HVAC system will save you energy – reducing electricity bills.
Energy saving is one of the concerns of the users, and the Department of Energy shows that heat pumps can reduce electricity used for heating by 50% as compared to furnaces, baseboard heaters, etc. Opt for the most energy-efficient cooling unit for your home. Verify energy efficiency ratios and look out for SEER ratings and smart functionalities that can help increase your savings.
5. Energy Saving Devices
With the progress and advancement in technology, the selection of relevant smart devices can help you in saving and optimizing your home energy. Such devices use minimum energy to function as compared to regular appliances, thus further reducing your electricity bills. An energy-efficient home needs to be smart to give a good return on investment and save money in the longer run.
You can utilize smart AC controllers, smart thermostats, smart bulbs, smart blinds, kitchen appliances, etc., to equip your smart home. Taking the example of smart AC controllers, they function by regulating your air conditioner usage according to your usage habits throughout the day helping you save 25% on your cooling and heating bills. They can also be coupled with other smart home climate control appliances connected with Alexa or Google Home for further benefits.
6. Lighting Fixtures
Every building/home uses an interior and exterior lighting system, which might consume a lot of energy depending on the type of lighting fixtures or bulbs used. According to research by the U.S Energy Information Administration, light accounts for 14% of the electrical budget for an average home in the United States. Thus, it is advised to use fluorescent bulbs and LEDs because they generate less heat and more light, ultimately helping you save energy. LEDs provide good returns on investment and can fit in most of the light fittings.
Apart from LEDs and bulbs, the building’s windows can be designed so that natural light can reduce the need for artificial light during the day. Moreover, aluminum-clad wood can be used for window frames since these windows provide better insulation making your home energy efficient.
7. Building Envelope
You protect your smartphone from scratches by using a glass protector or an external cover, right? Similarly, a building envelope serves as a protector or covering for a house. The outer structure of the building is called the building envelope, and it is one of the necessary energy systems. It works as a shield between the inside and outside environment, protecting the house from the air, moisture, and generally harsh weather conditions.
Considering the type of insulation used, the building envelope maintains the interior temperature at any level that you desire. It can keep your home warm during winters and cool during summers. It is essential to consider an energy-efficient home design.
Body envelope includes insulation which can be very beneficial for energy saving. It lowers the load on the house’s heating and cooling system and makes your home more energy-efficient. It maintains the desired temperature at home and absorbs moisture, and saves your walls from being damaged.
8. Design for Water Conservation
An increasing number of energy-efficient houses are incorporating water-saving systems. For instance, homeowners are going for greywater recycling systems. Greywater is the waste water from showers, sinks, laundry tubs, and washing machines. You can have a diversion system installed that carries the greywater from your washing machine to your bathroom or your garden.
This system can decrease your water usage by about 50%, helping reduce your water bills.
Moreover, you can also save water during the shower and washing dishes by incorporating new technology in your house. New low-flow water fixtures in the kitchen and showers reduce the amount of water coming out of them but distribute it more evenly.
9. Roofing Materials
The roofing material is another important consideration when building an energy-efficient home. The material used for the roof of your house can absorb less heat by deflecting the sunlight, thus maintaining a constant temperature of your home. The choice of roofing materials makes a difference in overall energy efficiency. The materials used to build the roof help you with energy conservation, decrease air pollution and greenhouse gas emissions, and keep your home cool without air conditioning.
Initially, the selection of a roof could be expensive, but in the long run, it pays back and reduces your bill by regulating the temperature of your home during summers.
10. Go Solar
According to the latest U.S. residential solar market report, the residential solar market in the U.S reached a record high in the third quarter of 2019 with 712 megawatts of solar panels installed. Solar Panels can help build energy-efficient homes. If your area is exposed to the sun throughout the year, then solar panels will surely reduce your electricity bills. These panels don’t require extensive maintenance, so it’s a one-time investment that saves you from a lot of hassle and makes you self-sufficient.
Solar panels are an environmentally friendly option since solar energy is converted into electrical energy, reducing harmful greenhouse gases that contribute to global warming.
