Bayer AG n Z e B S a n d I n d I a’ S F u t u r e B u I L d I n g g r O w t h The EcoCommercial Building is one of only a few net zero energy buildings in India. While initial project costs were significantly higher than typical commercial construction costs, the investment is providing reduced operating expenses for the long term. consumption of HVAC, lighting and other related areas were compared with the monthly baseline consumption figures provided through energy modeling (see 2011 Actual Energy Use Vs. Calibrated Baseline). Metered systems include the main incoming power supply, chillers, internal lighting, external lighting, air-handling units, the water supply system, the sewage treatment plant and the solar PV system. The commissioning team did not identify any aspects of the project that needed improvement. This project’s innovative design and its high performance that meets design goals demonstrate the effectiveness of integrated project delivery. Solar PV The project’s 57 kW crystalline silicon grid-connected solar system is expected to generate 88.9 MWh/year. It produced 72 MWh during 2011 due to mutual shading of the panels in a few 52 Buildings account for 33% of the total electricity consumption in India. An estimated 70% of the building stock required for 2030 has not yet been built. This formidable growth in the construction industry and the resulting energy demand is predicted to increase dependence on imported fuel, contribute to higher greenhouse gas emissions, and strain the country’s fossil fuel dependent infrastructure. While implementing minimum energy performance standards for buildings will contribute toward checking the increasing energy demand, net zero energy goals are needed for energy security. The U.S. Agency for International Development (USAID) launched a five-year program in July 2012 in partnership with India’s Ministry of Power and the Ministry of New and Renewable Energy that aims to accelerate India’s transition to a high performing, low emissions and energy secure economy. In the building sector, the program involves promoting energy efficiency and net zero energy goals. Activities include technical resource development, capacity building, demonstration projects, Energy Conservation Building Code (ECBC) implementation support and updating the ECBC 2007 with provision for NZEB components.

The excess energy is fed into the existing adjacent building within the campus. park. The site is supported by wellconnected public transportation. Bayer also provides buses to transport employees to various parts of Delhi and its satellite cities. Other Sustainable Features Site Selection. The EcoCommercial Building is a part of Bayer’s factory campus located in an industrial Water. Rainwater harvesting pits 3 m (10 ft) in diameter and 5 m (16 ft) deep are located in all four LeSSOnS Learned Integrated Project Delivery. This method was a key to developing this building. All of the stakeholders were included in the design process from the beginning. The basic intent of the EcoCommercial Building’s design is to reduce the energy demand through implementing highly efficient energy conservation measures. This reduced energy demand enabled the owner to make an early decision to implement a photovoltaic system and pursue net zero energy status. Higher Initial Costs, Lower Operating Costs. The cost of the building is relatively high compared to typical commercial building in this region. The material and the technology used such us as photovoltaic cells for power generation, chiller plant and chilled beams, sewage treatment plant, rainwater harvesting system, additional insulation, energy-efficient windows, cladding materials and LEED-certified office furniture increased the project cost significantly. This initial HigH Performing Buildings fa l l 2 0 1 3 investment has considerably decreased the operating cost of this building. Integrating Services Without Hampering Design. An exposed ceiling is designed to showcase the chilled beams, a new concept for providing air conditioning in India. Making the exposed ceiling aesthetically pleasing and fully functional presented a challenge. Each service element, including chilled water pipes, conduit, light fittings, chilled beams, speakers, smoke detectors, motion sensors, etc., was meticulously coordinated by the designer, project manager, and electrical and HVAC vendors to achieve the desired result. Grand Opening Activities May Explain Higher Energy Use. The building’s first year EUI of 22.73 kBtu/ft2·yr is slightly higher than the modeled EUI of 19.1 kBtu/ft2·yr. The model did not account for the grand opening presentations and tours, which may explain the higher than expected EUI.
