What is Green Building?
You might be thinking that green building means planting different types of plants in and around residential and commercial spaces. But green building is a building by which the negative impacts got lessen down due to design, construction and usage. You can see positive impacts on the surrounding climate. Green building safeguards natural resources and makes our life better. Green buildings are constructed by the use of reused and recycled of all building materials so that green building can be made efficient and environment friendly. Mostly renewable energy is used in the green building.
Purpose of Green Buildings
- Protecting health
- Improving employees productivity
- Conservation of energy, water and natural resources
- Reduction in CO2 emissions
- Reduction of pollution and global warming
- Use of non-toxic and sustainable materials
- The building is suitable for all conditions
What are the different types of green building technology?
1. Net-zero concepts
Net-zero concepts mean a building which generates energy from renewable energy sources. This technology produces surplus energy based on the energy requirement. Hence, they are called ‘Energy Plus Buildings’.On the other hand, those buildings which generate less energy than required, it is called ‘ Near Zero Energy Building’.Especially these buildings every year zero energy loss and do not create any type of Co2 emissions
2. HVAC (Heating, Ventilation and Air Conditioning)
Almost every building’s 50% of energy is used on HVAC. In this context, the HVAC system is very effective. With the help of the HVAC system, one can control on cool, warm and dehumidifying air in your home and offices to take care of your comfort. The HVAC system consists of water-cooled chillers which control the temperature inside the building. The purpose of the HVAC system is to ensure minimum electricity usage for the building’s energy requirement maintaining required comfort levels of occupants.
3. Low emitting materials
Low emitting materials means the materials by which there would not be any harm to the chemical reaction, air quality, productivity and environment. All the materials in low emitting materials are non-toxic and sustainable. Generally, low emitting materials are used in many areas in a building like interior paints & coating, flooring, composite woods, ceilings, walls, thermal insulations etc.
4. Solar power
It’s not possible to mention green building without solar power. There are 2 types of solar power viz. Active solar power and passive solar power.
- Active solar power- It converts radiations from the sun into electricity to utilize household appliances. This technology involves a lot of initial costs but it helps to provide fewer utility bills for a long time and reduce greenhouse gases into the environment.
- Passive solar power -It depends on the proper placement of windows which absorbs heat and convert it into energy.
5. Green insulation
Green insulation is mainly made from Cellulose which results from newspaper recycling. It is necessary to insulate a building. Insulating materials are of various sizes like wool insulation, slag and slabs, natural fibre insulation,porotherm bricks, perlite insulation, cementitious foam insulation etc.
6. Water conservation
Water conservation is the green building’s basic principle. The building is constructed and designed in a way that occupants require as much less water as possible in a day to day life. Rainwater harvesting plays the main role in water conservation so that rainwater can be collected and you can use that water for direct use or stored in groundwater. You can even make it suitable for drinking purpose after proper treatment and filtration. The water is also reused and recycled to fulfil basic water needs.
Top Certifications for Green Building
Green building initiatives helps to appreciate the property value significantly. There are various certifications in the U.S and around the world to showcase your company’s goal on sustainability to prospective investors and tenants. The right option will rely on what the certification’s aim is and what limitations you’re dealing with.
Top 3 green building certifications are as follows :
LEED probably has the widest international recognition. It could therefore deliver the best financial return on investment. LEED also includes a detailed solution if you are involved in the greenest possible braking of the building. It is an expensive one though.
The highest class benchmark program and green building certification scheme administered by the U.S. is LEED (Leadership in Energy and Environmental Design). Council of Green Building (USGBC).LEED focuses its efforts on enhancing performance in five main environmental and human health areas: energy conservation, quality of the indoor climate, sustainable selection of materials, sustainable site creation and reduction of water usage. Building projects are needed to meet certain prerequisites in order to obtain LEED certification and gain LEED points from any of the four registered,
- 40-49 credits for normal LEED-certified buildings
- 50-59 credit for silver LEED-certified buildings
- 60-79 credit for Gold LEED-certified buildings
- 80 plus credits for Platinum-certified LEED buildings
2. Energy Star
Energy Star is the energy efficiency icon sponsored by the government, offering clear, reliable and impartial information on which consumers and businesses rely to make well-informed choices. The instruments and tools help corporations to find cost-effective approaches to controlling their buildings and plants’ energy usage, allowing the private sector to conserve energy, raise profits, and improve their competitiveness.
Benefits of Energy Star ratings :
- Direct Savings: Going through the process to become energy star certified ensures that you measure, monitor and improve energy usage, resulting in achieving and maintaining energy savings (dollars and kWh)
- Higher occupancy: Tenant comfort and occupancy rates are higher in energy star labeled buildings
- Higher asset valuations: Reliably persistent energy savings result in higher margins, which translate to higher asset valuations.
BREEAM signify ‘Building Research Establishment Environmental Assessment Method’. It was invented by BRE, a building research organisation funded mainly by the UK government. This organization aims to provide the construction industry with applicable research and knowledge on what kind of approaches will better help the conservation of the environment and sustainable growth.
In the following places, BREEAM evaluates the efficiency of buildings:
- Management: Overall management strategy, management of the commissioning site and procedural problems.
- Energy use: Problems related to operational energy and carbon dioxide( CO2).
- Health and well-being: It is influenced by indoor and external problems.
- Pollution: air and water pollution issues.
- Transport: transport-related CO2 and location-related factors.
- Land use: greenfield and brownfield sites.
- Ecology: Maintenance of ecological value and site development.
- Materials: Environmental effects of construction materials, including impacts on the life cycle.
- Water: Consumption and water efficiency.
Financial benefits of green building
If these benefits are directly or indirectly related to green building, green buildings have a range of financial benefits.
1. Upfront costs
The upfront costs of building green are significantly higher when compared to building normal. The explanation for this may be the misconceptions of green building costs; the propensity to neglect historical data when green materials are more costly; or additional expensive finishes that are not explicitly related to green costs. The cost premium may be the same for green buildings and, in some cases, even lower than for traditional buildings.
2. Lack of Knowledge
There is a general lack of knowledge of green buildings. This has an adverse effect on green building construction in general. Many experts are licensed and perform courses with green building councils, which ensures that it will only be a matter of time before they gain the requisite expertise.
3. Green materials become cheaper
The cost of green materials used in construction is becoming cheaper.
4. Long Term savings
Green buildings can contribute to long-term savings and that a realistic comparison of costs between building green and building normal can only be obtained over the lifecycle of the building.
5. Operational cost
Energy and water conservation concepts are synonymous with green buildings and the cost of these things is a significant contributor to the operating cost of a building. Efficiency in these areas is a green building’s financial advantage.
6. Return on investment
The strategies used in green buildings and the lower operating costs pertaining to green buildings will inevitably result in a higher ROI when compared to that of a normal building. The significant savings in operating costs results in an increased net income which increases the building’s appraised value.
Green buildings are an important issue internationally and, as a result, buildings that comply with green building requirements receive a lot of free advertising and media attention, which eventually ensures that green building-related businesses will ultimately benefit from it in the long run.
Production is often the differentiator when it comes to the profitability of a company. Green buildings have an environment free from harmful toxins and chemicals that have a beneficial effect on the productivity of the worker. Green buildings have a healthier workspace that contributes to decreased absenteeism, contributing to improved productivity.
Tenants of commercial buildings ultimately provide the income for property letting businesses. The financial advantages associated with green buildings indirectly favor tenants, as lower maintenance costs would have a beneficial effect on owners’ rental rates. The lower rental rates paid would foster loyalty to tenants.
10. Liability and risk
In the future, green buildings would not only restrict sharp rises in utility rates but also reduce the burden on the natural resources of the planet.
