The new construction provides architects, contractors and building owners with the opportunity to design and construct an energy efficient building and even a pure zero energy project.
Pure zero energy building consumes less or equal to the energy generated on site by renewable resources. The steps to build a modern energy efficient infrastructure begin with choosing a site and implementing a detailed, comprehensive design plan.
Efficient Design of Building:
Implementing access to the entire building system until new construction is an effective way to achieve an energy efficient building. The whole building’s approach treats the building as an energy system with separate, but dependent parts. Each component affects the performance of the entire system. This design should make efficient use of water and electricity and other natural resources and energy sources. Select the smallest building for the desired application to minimize waste and commodities. The purpose of a sustainable design is to reduce the lack of important resources such as land, water, energy and raw materials. The durable design of facilities and infrastructure also prevents the destruction of the ecosystem.
Wall Insulation of Building:
An efficient building requires a stable layer of insulation around the building envelope. Continuous insulation increases the effective R-value of the structure, eliminates condensation, and creates a comfortable space for the building’s occupants. Since it is strongly sealed, energy-efficient, wood-framed buildings are at risk of moisture accumulation in the wall cavities, so the exterior of the building must be wrapped in water-repellent and breathable material. Moisture in the walls of a building is serious as moisture can lead to wood rot (due to fungi) and costly repairs. Humidity can also cause mold development, which is unhealthy for those living on the structure. It is important that the envelope of the wood-framed building controls the entry, collection and removal of moisture.
Ventilation in an Energy-Efficient Building
Roper ventilation is essential for an energy-efficient home because air sealing techniques can trap pollutants (such as formaldehyde, volatile organic compounds and radons). Ventilation also helps to control moisture, which can lead to mold growth and structural damage. An energy efficient building should include an energy recovery ventilation system.
The energy recovery ventilation system provides controlled ventilation and minimizes energy loss by transferring the conditioned air to the latest incoming air. Install local exhaust fans to create space ventilation above the kitchen limits and in bathrooms.
Spot ventilation improves the effectiveness of natural and entire home ventilation by eliminating indoor air pollution and humidity. Natural ventilation is the least expensive and most energy-efficient way of cooling buildings, while spot ventilation, ceiling fans and together work. For large homes and buildings, fans of entire buildings are a worthwhile investment.
Heating and Cooling Systems of an Energy Efficient Building
The biggest energy costs in homes and commercial buildings are cooling, heating and heating of water. Energy efficient measures must be incorporated into a building’s heating and cooling system to create an energy efficient structure. Select a high energy efficient heating, ventilation and air conditioning system. Replace the air filter of the HVAC system recommended by the equipment manufacturer.
Dirty filters reduce air flow and make the system work harder to keep the building warm or cool. Also, a clean filter prevents dust and dirt from getting into the system.
Dust and dirt in the HVAC can lead to costly maintenance and failure of the initial system. To save energy the building seals the drains that move from the HVAC system to the air. Attaching seals to crawlies, crawlspaces, non-heated braces or garage drains is especially important.
Seal drain seals and connections with sealant (mastic) or metal backing tape, then wrap the drains into the insulation. The insulation will maintain drains in the cold and warm in the winter.
