Early stage analysis reduces energy use of proposed building by 60 percent
Integrated Environmental Solutions’ (IES) award winning performance analysis software suite, the Virtual Environment, played an important role in the sustainable development of Central Karakorum National Park (CKNP) in Pakistan. Energy technology firm E++ and ILA Studio architects used IES’ VE-Pro software to determine the climactic and environmental impacts on the proposed design of a 5,000 sq. ft. park headquarters.
Using VE-Pro modules MacroFlo, ApacheSim, ApacheHVAC and ApacheCalc, E++ and ILA Studio performed early stage analysis to determine the building’s energy consumption, performance and occupant comfort. The initial simulation showed the building to be of poor performance with regards to heating, primary energy consumption and summer comfort. Analyzing the design early on, the team was able to evaluate a series of improvements that ultimately resulted in a 60 percent decrease in primary energy heating consumption.
“This project highlights the advantages of integrating IES VE with design at the earliest stage possible,” said Alberto Altavilla, Head of Building at E++. “Performance analysis throughout the design process allowed us to evaluate and make appropriate design choices to ensure that this building is as energy efficient as possible.”
The advantages of design simulations are key to sustainable design. E++ and ILA Studio expected the opposite in terms of orientation when the team ran a summer simulation. As it turned out, the optimum orientation of the building was contrary to the main wind direction. The design proposal also incorporated several energy improvements to the building, including a Passive Double Skin Facade that would preheat air in the heating mode and remove unwanted heat gain during the summer, increasing cross ventilation capacity.
“We are excited to be a part of the sustainable development of Central Karakorum National Park in Pakistan,” said Dr. Don McLean, founder and CEO of IES. “Our early stage analysis tools have helped E++ and ILA Studio make critical improvements that will significantly reduce energy costs and greenhouse gas emissions.”
