The Passive House Planning Package (PHPP)

Passive House buildings and energy efficient projects which are carefully planned using the PHPP have proven successful. Whether new builds or retrofits, building projects that achieve the Passive House Standards meet the level of comfort and the extremely low energy demand being strived for. The PHPP is continually being validated and extended on the basis of measured values and new research findings.
In the context of accompanying scientific research in several objects, measured results were compared with the calculated results. In the process, a high correlation could be demonstrated between the demand calculated using the PHPP and the consumption ascertained through scientific monitoring projects.

An ideal instrument for realising NZEBs
The possibility of planning and assessing efficient projects in a reliable way makes the PHPP an ideal planning tool for the implementation of NZEBs (Nearly Zero-Energy Buildings) or other buildings which are also optimised for low energy consumption. Proven successful over many years, PHPP is also useful for the calculation of NZEB’s which are now being strived for in Europe and worldwide. This is the case in spite of the different national expressions this definition may take, with reference to the detailed characteristics of the projects.

Energy- and cost-efficient, façade-integrated daylight and led illumination based on micro-optical components

Energy efficiency, life cycle balances and indoor comfort shall be improved by employing micro-structured optical components for daylighting and electrical lighting. There are two compatible micro-optical structures under development that can be combined with one another, namely

• Light-redirecting structures, which are applied to both sides of transparent substrate layers and are being optimized for redirecting glare-free daylight deeply into the building interior;
• Light-emitting structures at the surface of transparent substrates, which emit laterally injected LED light specifically on one side only. The element remains transparent when viewed from above (plan view).

The optical structures will be integrated into the building envelope in different ways:

• When integrated into vertical facades, these structures allow the sunlight directly incident from a wide range of solar altitudes to be redirected into spaces located deep inside the building interior, namely without sun tracking.
• When integrated into rooflights, they allow for improved lighting of low-lying areas in high, narrow spaces (e.g. atria or light wells).
• As the artificial-light emitting structure is integrated in windows and rooflights, future building envelopes will also be able to supply artificial lighting, besides providing virtually unlimited natural lighting. In some cases, conventional indoor lighting systems may hence be waived.

This joint project is funded by the Federal Ministry for Economic Affairs and Energy (BMWi) (Project Management Jülich). Project partners are Fraunhofer Institute for Building Physics (IBP), Green Building R&D GmbH, Karl Jungbecker GmbH, durlum GmbH, RIF e.V. Institute for Research and Transfer TU Dortmund, Saint-Gobain Sekurit Deutschland GmbH & Co. KG, Temicon GmbH, Schürmann Spannel AG (SSP) and ai3 / Dr.-Ing. Werner Jager.

Active House Specifications

Active House is a vision of buildings that create healthier and more comfortable lives for their occupants without impacting negatively on the climate – moving us towards a cleaner, healthier and safer world. The Active House vision defines highly ambitious long-term goals for the future building stock. The purpose of the vision is to unite interested parties based on a balanced and holistic approach to building design and performance, and to facilitate cooperation on such activities as building projects, product development, research initiatives and performance targets that can move us further towards the vision. The Active House principles propose a target framework for how to design and renovate buildings that contribute positively to human health and well-being by focusing on the indoor and outdoor environment and the use of renewable energy. An Active House is evaluated on the basis of the interaction between energy consumption, indoor climate conditions and impact on the environment.

In the Task 56 we are using the Active House Specification Radar in the following projects; Lykkebo School, Grøndalsvænget School, Living in Light Box and Gl. Jernabanevej. In the two first projects (Lykkebo and Grøndalsvænget School) we are evaluating the effect that the ventilation projects have had on the comfort (CO2 and temperature). In the Living in Light Box (a small office building) and Gl. Jernbanevej (multi-storeyed dwelling) we are making a total evaluating where all three categories of the Active House Radar is included; comfort, energy and environment.

Building-Integrated Solar Systems: Overview of Recent and Current Work at Concordia University

The Center for Zero Energy Building Studies (CZEBS) of Concordia University has been a leader in several research Networks and has a significant academic contribution in the past years. Part of this research is held at the unique Solar Simulator and Environmental Chamber of Concordia University. Also Concordia University contributed at the design and the realization of projects towards the Net-zero energy goal such as the EcoTerra house, the BIPV/T system at the John Molson School of Business, the Varennes Library and other. Currently, air-based BIPV/T systems for integration in spandrels or in curtainwall are investigated. In addition, new technologies such as semi-transparent Photovoltaics and Double Skin Facades integrating Photovoltaic panels are tested and characterized at the facilities of Concordia University. Also Concordia University is participating at the Solar Decathlon China 2017 competition representing Canada and is part of several other Net-Zero energy building projects.

Building Integrated Solar Heating by SolarWall

Space heating accounts for over 50% of buildings’ energy needs in northern climates and large surfaces free of snow are necessary to meet this demand. SolarWall® is a solar heating technology that is integrated into the south façade and is being used around the world in 40 countries. It heats air directly for maximum efficiency and it can either blend into the façade or become an architectural feature. Numerous photos of many building types were presented to show the versatility and attractive appearance of building integrated solar air collectors.

DALEC – Day- and Artificial Light with Energy Calculation

Building design significantly affects the energy demand of the building. Especially the façade system determines the solar gain, and as a result the demand for heating, cooling and artificial light. A realistic evalution of the building behavior so far can only be done by a coupled light and thermal simulation – a costly and time-consuming task to undertake by building experts. The newly developed Online-Analysis-Tool DALEC allows architects, building engineers, light planner and building owner to analyse the effects of their early- stage façade concepts in an intuitively accessible way. All relevant complex physical processes are considered with high accuracy while the input efforts and calculation time is minimized. In this way for instance different façade systems can be compared regarding their impact on annual daylighting, artificial lighting demand, heating and cooling demand and user comfort by a well-structured graphical illustration. A future edition will enlarge the functionality to further visual and thermal comfort criteria, will enable evaluation of complex buildings and will further simplify direct design comparisons.
