Technology Recommendations - Background Info
This section provides an overview of energy efficient solutions and systems which are currently available for retrofitting in buildings and districts under the low energy use criteria.
The Solutions and Systems are classified in five main categories, Envelope, Lighting, Improved Services, Elevators and Renewable Energy (production and storage), leading to 17 sub-categories as listed below:
When considering Low Energy Criteria and selecting the solutions to improve building performance, it is recommended that the following steps or hierarchy are followed:
- Develop the design of the envelopes and interiors using ENVELOPE solutions to minimize the heating and cooling loads of buildings.
- Analyze all of the daylighting opportunities included in LIGHTING category. These have a double benefit: the energy use is reduced and a smaller-size HVAC system is needed.
- Then select the HVAC to ensure systems energy efficiency under the IMPROVED SERVICE category,
- Choose ELEVATORs along with
- The use of RENEWABLE ENERGY sources for production and storage.
Also view the synergies among different interventions areas and at district scale (ASHRAE, GreenGuide 2010).
These Solutions are suitable for different Climates, Building Uses, Building Characteristics and Retrofitting criteria Therefore in order to carry out the search and make the best selection for the technologies, the following information has been inserted for each of the different fields below:
|WHAT: Provides a short description of the technology, system or tool and explains how it works. It identifies the technological readiness or maturity of the solution and identifies the suitability at district/building or component scale application.
WHY: Provides specific advantages and disadvantages relative to equivalent technologies.
WHEN: These fields identify space requirements, weather and operational conditions at which the technology performs best.
WHERE: These fields provide information on the price range of the solution and the potential suitability on cross-cutting issues with other technologies.
Technology Recommendations - Help
When your building was added at an earlier stage, the characteristics of that building were defined. This section allows you to view the technology recommendations specific to that building, based on your building characteristics.
Alternatively, you can view all of the technology recommendations by clicking the “No Building?” checkbox and choosing the technology category from the dropdown menu, then click View. All information can then be downloaded.
