success

– Ernestas Beržanskis, Intelligent BIM Solutions

• 13:45 Why we should do Building Performance Analysis, what is a benefits?

– Michelle Farrell, IES Ltd

• 14:30 Building performance analysis system IES VE main features overview

– Karolis Januševičius, Intelligent BIM Solutions

• 15:30 Discussion: how to promote green and energy efficient design solutions in Latvia, foreign experience

A key of success is right process (what, when & how)

What should we do to improve buildings performance?

When should we care about building performance analysis?

Comfort level and Energy saving

• Latvia’s Energy Development Guidelines 2007-2016 aim to reduce the average heat consumption in buildings by at least 11 percent over the period and to improve energy efficiency in heat production installations.

• How to do it, how to find most efficient solutions to optimize building performance (comfort level and cost and energy savings)

Issues in building operation• Not enough comfort level

– Building users not very happy and require improvements (new heating, ventilation, etc.)

– If not, there are more modern buildings, technologies

• High operation costs– When we are planning building operation costs

– Operation cost vs construction cost

• Commercial buildings competition– Price is not enough to compete, new requirements

Building Costs

When its right time to make decisions on operation? Why we always surprised?
