HVAC for Green Buildings

Green is the idea for life in today’s world and so is comfortable indoor temperature setting to enjoy a better living.

Anything from incorporating excellent practices that result in environment protection, water conservation, energy efficiency, usage of recycled products and renewable energy, is termed “green”, and the list is endless.

Maintaining healthy indoor environment, maximum energy-efficiency, and thoughtful use of
natural resources (water, solar energy) are the core focus for any HVAC system and also represent the biggest challenge also.

In recent times concept of “Green Building” has also emerged and witnessed due importance in India too. A “Green Building” is one that is environmentally responsible, profitable and a healthy place to live and work.

Green Buildings ensure that waste is minimized at every stage during the construction and operation of the building, resulting in low costs.

Investment in the country’s infrastructure projects and Heating, Ventilation and air conditioning (HVAC) industry are directly related. Hence, growth in infra will always impact the HVAC industry positively.

Now with increasing development in retail, hospital, warehouses and other commercial spaces are increasing the potential of HVAC segment.

An HVAC designer plays an important role in the functionality of a green building. The HVAC system for green building shall be designed to reduce energy consumption while maintaining the interior conditions at a comfortable level to keep occupants health and productivity.

The designer should ensure the HVAC system design NOT only meet the standard on energy front but beat the standard codes like Energy Conservation Building Codes (ECBC), India & American Society of  Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) standards to achieve higher level of green building LEED (Leadership in Energy and Environmental Design) rating.

HVAC design follows other fundamental building steps that can collectively reduce the size of the heating and cooling system by 30-50%. Keeping in mind the requirement, proper analysis needs to be done before installing an HVAC system.

HVAC is a system designed as part of the building and works best when it takes local climate and building designs into account. In a green-built home, heating and cooling equipment can be smaller, less costly, and less complicated. Designing proper HVAC system is not to merely produce a heat loss/gain estimate and select high efficiency equipment.

It is only one step in achieving an efficient HVAC system. Equipment sizing, system design and installation will all determine the overall efficiency and performance of an HVAC system, further how well the system is maintained will determine its efficiency. HVAC system includes, chiller, cooling tower, chilled water pump, condenser water pump and air handling unit.

The total performance of a building depends on a balance of mechanical systems, occupants and external environment. All these parts of the building affect the flow of heat, air, and moisture into and out of the building.

Every sub-system should be designed with these concepts in mind to minimize the flows of heat, air, and moisture through the building envelope.

India is fast adopting the concept of green building and more and more residential and commercials are exploring every possibility of adopting the green concept. The overall installed capacity of the HVAC plant for a building will become greatly influenced by the Energy Conservation Measure (ECM) adopted for the building.

Recent developments and future of HVAC Industry due to Green Building Construction stays in chiller selection, ancillary HVAC equipment selection, outdoor air delivery system, supply air system control, indoor air quality monitoring, and energy conservation measure Strategies in HVAC System.

Efficient, properly designed and sized HVAC equipment increases comfort and reduces energy costs. It also reduces green house gas emissions. Considering the entire building design when designing HVAC systems allows easier installation and maintenance, reduces resistance to airflow, and increases efficiency.

Energy conservation, indoor air quality, and comfort are among the core green building issues encompassed by HVAC design.

Today’s world needs environment-friendly, energy conserving solutions and products. With increased global warming and environmental degradation, people around the world recognise that businesses must act responsibly and offer green products to customers.
Symphony enables people across the world to capitalise on eco–friendly, energy-saving air cooling technologies as a serious alternative to large energy consuming, non-eco friendly, ozone depleting, inefficient air-conditioners which cause global warming.

Symphony Ltd is a leading Indian company providing air cooling solutions for residential and industrial segment offering advanced, energy efficient cooling and humidification solutions. Having established a leadership position in the home air cooler segment, the company is all set to provide air cooling and humidification solution for industrial and commercial units.

Further acquisition of IMPCO, an American company with a plant in Mexico in 2008 has helped Symphony venture into the industrial & commercial air cooling market in India.
Symphony’s heavy duty industrial air coolers are manufactured in Impco’s state-of-the-art plant. These industrial air coolers provide cost-efficient environment-friendly cooling solutions for industrial and commercial applications.

Symphony is the only company to offer machine-made, engineered, modular units with cooling capacity ranging from 3,000 to 60, 000CFM. These units are made from automotive steel with PLASTISOL coating and POLYBOND powder-based coating that prevent corrosion and ensure durability.

Symphony’s industrial air coolers are designed to provide superior performance in warm workplace settings. It is ideal for factories, offices, schools, malls, assembly halls, warehouses, metro stations, among others. These coolers improve working conditions, leading to increased worker morale, productivity, attendance and performance.

Although there are several local players in this category, Symphony’s products are considered superior on account of their engineering, performance, energy efficiency and lower operating cost.

Symphony’s products have been endorsed by a number of corporate giants, namely General Electric (Illinois, USA), Wal-Mart Stores (Nevada, USA), Lear Corporation (USA), Jamarat Complex (Saudi Arabia) and more than 100 supermarkets in Mexico.

Symphony has executed industrial air cooling projects for the stores of retail majors like Wal-Mart, Sears & Home Depot in the Americas. In India, Symphony has done air cooling projects for industrial units of Maruti, Nestle, Hero Group, Asahi Glass, amongst many others.

The company has also done air cooling projects for religious institutions like Baba Ramdev, ISCKON and the Swaminarayan sect. Infact one of the world’s largest air cooling project was done for the Mecca Madina project, which was executed by Impco.

For the year ending, June 2013 Symphony Ltd earned a net profit of Rs. 60 crore on turnover of Rs 391 crore. Earnings per share (EPS) of the company for the year ended June 2013 was Rs17.18 per share and book value at Rs 63 per share.
