Ladybug is a free and open source environmental plugin for Grasshopper to help designers create an environmentally-conscious architectural design. The initial step in the design process should be the weather data analysis; a thorough understanding of the weather data will, more likely, lead designers to high-performance design decisions.

TRNSYS - a component based transient simulation package.

ENERWIN PRO© is a Windows-based hourly energy simulation model for evaluating whole-building energy performance and peak loads. The program features an interactive graphical interface for input and output and a built-in weather database for 4777 cities.. The simulation model uses algorithms that permit hour-by-hour energy calculations in minimal time and displays results in graphic form or in Microsoft Excel© if chosen. Full availability information at http://www.enerwin.com.

Tool for evaluation: energy efficiency ( electricity, wáter, fuel oil, etc...), CO2, H2O, Savings, abatement curves in Buildings of Institutions (Health Care, University, Army Forces, School, Government, etc.)

Insight 360 empowers architects and integrated teams with centralized access to performance data and advanced analysis engines. Through robust integration with Revit and FormIt 360 and direct access to guidance and recommendations from trusted simulation engines and industry benchmarks, architects can approach the design process with understanding of the elements that lead to better building performance outcomes throughout the building lifecycle.

SEMERGY® is a Web-based building optimization system that supports the planning of energy-efficient construction and refurbishment projects. It allows users to specify the properties of their buildings including size, type and geometry, identifies potential refurbishment options, evaluates the different options, etc. and suggests the optimal renovation solution with respect to energy savings, cost saving potential, and sustainability of building products.

Measurabl is sustainability reporting software built to help you collect, report, and act upon non-financial data. You can effortlessly collect utility, waste and travel data, create and e-File financial-grade reports on demand, and analyze sustainability KPIs to make improvements.

Lesosai allows the calculation of environmental impacts of the energy consumption, taking into account the energy used in the building, but also the building's construction materials (Life Cycle Impacts Analysis / Environmental Assessment). To calculate the heat transfer coefficient (U-value) we have integrated the software USai, which allows the creation of constructions and materials while controlling condensation. It also allows you to synchronize the database with those of the many materials producers who participate in the materialsdb.org project. To simulate buildings anywhere in the world, Lesosai includes the meteorological data generator, Meteonorm®. Lesosai include many official meteorological data. Lesosai can also calculate required heating power, following EN 12831 by zone or by room. The hourly calculations following EN ISO 13790 are validated with the help of tests following EN 15265. Lesosai offers the possibility of calculating the thermal inertia of the building by introducing layers of walls (calculation possible under the standard SIA180 and EN ISO 13786).
