A Trombe wall is a massive equator-facing wall that is painted a dark color in order to absorb thermal energy from incident sunlight and covered with a glass on the outside with an insulating air-gap between the wall and the glaze. A Trombe wall is a passive solar building design strategy that adopts the concept of indirect-gain, where sunlight first strikes a solar energy collection surface in contact with a thermal mass of air. The sunlight absorbed by the mass is converted to thermal energy (heat) and then transferred into the living space.
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
A solar chimney – often referred to as a thermal chimney – is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.
Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR) or energy recovery ventilation (ERV), is a ventilation system that recovers energy by operating between two air sources at different temperatures. It is used to reduce the heating and cooling demands of buildings.
A louver or louvre is a window blind or shutter with horizontal slats that are angled to admit light and air, but to keep out rain and direct sunshine. The angle of the slats may be adjustable, usually in blinds and windows, or fixed.
Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC, electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption, reduced operating and maintaining costs and increased security.
Building regulations in the United Kingdom are statutory instruments or statutory regulations that seek to ensure that the policies set out in the relevant legislation are carried out. Building regulations approval is required for most building work in the UK. Building regulations that apply across England and Wales are set out in the Building Act 1984 while those that apply across Scotland are set out in the Building (Scotland) Act 2003. The Act in England and Wales permits detailed regulations to be made by the Secretary of State. The regulations made under the Act have been periodically updated, rewritten or consolidated, with the latest and current version being the Building Regulations 2010. The UK Government is responsible for the relevant legislation and administration in England, the Welsh Government is the responsible body in Wales, the Scottish Government is responsible for the issue in Scotland, and the Northern Ireland Executive has responsibility within its jurisdiction. There are very similar Building Regulations in the Republic of Ireland. The Building Regulations 2010 have recently been updated by the Building Safety Act 2022.
Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. This approach works either by preventing heat from entering the interior or by removing heat from the building.

Ground broke on the tower on 8 September 2006 and construction was completed in March 2011. It is intended for office use and is partially occupied by the China National Tobacco Corporation.
Council House 2 (also known as CH2), is an office building located at 240 Little Collins Street in the Melbourne central business district, Australia. It is used by the City of Melbourne council, and in April 2005, became the first purpose-built office building in Australia to achieve a maximum Six Green Star rating, certified by the Green Building Council of Australia. CH2 officially opened in August 2006.
The Lake Ainsworth Recreation Hall is a multi-purpose recreation hall, used for basketball, netball, badminton and other sports, as well as meetings, films and theatrical performances that is located at Lennox Head, in Northern New South Wales, Australia. The building was designed in 2005 by architectural firm Allen Jack+Cottier, replacing an old, worn-out indoor sports facility.
A skylight is a light-permitting structure or window, usually made of transparent or translucent glass, that forms all or part of the roof space of a building for daylighting and ventilation purposes.
The Swanston Academic building is an RMIT building designed by the architecture firm Lyons and is located on Swanston Street in Melbourne across from Peter Corrigan designed building 8 and ARM's Storey Hall. Construction began in September 2010 and was completed in September 2012. The budget for the SAB was $200,000,000. The new building contains 35,000 square metres (380,000 sq ft) of floor space, is 11 storeys high and provides 6 large lecture theatres for students. The colourful building is intended to reflect the cities surroundings in the façade. “The idea is to wear the ‘cloak’ of the city”.
ENERPOS is the first educational net-zero energy building in the tropics and one of the 13 Net ZEBs in the tropics thanks to its bioclimatic design. Its name comes from the French "énergie positive". ENERPOS is located on Réunion Island, a French territory in the Indian Ocean. Building an energy-efficient building in such a climate is particularly challenging, but the energy expectations with regard to ENERPOS have been reached, even largely exceeded. ENERPOS is not only an energy-efficient building but also displays various passive methods to reduce energy consumption while providing a comfortable environment for its users. Classes are hosted for both undergraduate diploma and degree courses as well as for the Department of Construction and Energy at the Graduate Engineering School of Réunion Island.
The David Brower Center is a nonprofit space located in downtown Berkeley, California, containing three floors of office space, a gallery focusing primarily on environmental and social art, conference facilities, a 178-seat theater, and a restaurant, Gather. It was named to honor David Brower, a Berkeley native who was the first executive director of the Sierra Club and a backer of Marion Edey’s founding of the League of Conservation Voters. The center is part of a larger mixed use development that includes the Oxford Plaza. The David Brower Center's mission is to "inspire and nurture current and future generations of leaders, with the goal of making sustainable thinking and practices mainstream."
Passive survivability refers to a building's ability to maintain critical life-support conditions in the event of extended loss of power, heating fuel, or water. This idea proposes that designers should incorporate ways for a building to continue sheltering inhabitants for an extended period of time during and after a disaster situation, whether it be a storm that causes a power outage, a drought which limits water supply, or any other possible event.
In building engineering, a climate-adaptive building shell (CABS) is a facade or roof that interacts with the variability of its environment in a dynamic way. Conventional structures have static building envelopes and therefore cannot act in response to changing weather conditions and occupant requirements. Well-designed CABS have two main functions: they contribute to energy-saving for heating, cooling, ventilation, and lighting, and they induce a positive impact on the indoor environmental quality of buildings.
The David and Lucile Packard Foundation Headquarters is the corporate headquarters of the David and Lucile Packard Foundation, located in Los Altos, California. The Packard Foundation was created in 1964 by David Packard and his wife Lucile Salter Packard, one of the top 100 grant-making foundations in the United States, with the goals of improving the lives of children, enabling the creative pursuit of science, advancing reproductive health, and conserving and restoring the Earth’s natural systems. The David and Lucile Packard Foundation Headquarters is designed by EHDD to be the largest net zero energy building in California, and it has successfully reduced the energy use by 65% over conventional buildings.
IDA IndoorClimate andEnergy is a Building performance simulation (BPS) software. IDA ICE is a simulation application for the multi-zonal and dynamic study of indoor climate phenomena as well as energy use. The implemented models are state of the art, many studies show that simulation results and measured data compare well.
Ventilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption. Ventilative cooling strategies are applied in a wide range of buildings and may even be critical to realize renovated or new high efficient buildings and zero-energy buildings (ZEBs). Ventilation is present in buildings mainly for air quality reasons. It can be used additionally to remove both excess heat gains, as well as increase the velocity of the air and thereby widen the thermal comfort range. Ventilative cooling is assessed by long-term evaluation indices. Ventilative cooling is dependent on the availability of appropriate external conditions and on the thermal physical characteristics of the building.
